2021 Honda Odyssey: Recalls, Complaints & California Lemon Law

System crackles through the speakers and infotainment system shuts down completely. It may or may not reboot.. Most recently the screen was completely unresponsive, the radio would not turn off manually, and it did not turn off when the car turned off and the door was opened. Occurrence is random. The system may work fine for a few months and then crash multiple times daily and then go back to working normal again for a few months.

The rearview camera that does not display an image which can reduce the driver's rear view, increasing the risk of a crash or injury. I had the vehicle inspected by a third party which believes this could be from insufficient repairs as part of the prior recall NHTSA ID Number: 23V431000 related to this same issue. Honda's recall service center's only solution is that I take the vehicle to a Honda dealership for inspection, at my expense, and that they will reimburse me if they determine it is related to this recall. The issue with the display not working has been going on for several weeks. The display will work temporarily when the battery is reset, the fuse is reset, or when the display itself was removed/replaced by the party I had inspect the unit.

My rear hatch for the trunk was filling up with water every time it rained. Took it in to be looked at and they found the door wasn’t sealed during manufacturing and they sealed it. The water damage was already done and buttons for all things no longer lifts or opens the trunk door. My dash displays “ power tailgate problem” and nothing works to open it. I have to do it manually and I’m afraid it will cause further problems to the door.

Component or System Failed: Idle Stop System – The vehicle completely shuts off and requires a full restart at red lights or when stopped for several minutes. Safety Risk: The vehicle shutting off unexpectedly in traffic poses a serious safety hazard to both occupants and nearby drivers, especially when traveling with young children. I am genuinely fearful for our safety — particularly at red lights, where the risk of being rear-ended is high. There are numerous reports online of this same issue occurring in Honda Odyssey vehicles, indicating a wider safety concern. Reproduction of Issue: I have contacted both Honda and the dealership, and no effective solution has been provided. This vehicle is not safe to operate under these conditions. Inspection: The issue has been inspected by the Honda dealership, but no permanent resolution has been offered. Warning Lamps/Messages: There were no warning lights, messages, or alerts prior to the failure. The vehicle shuts off without any prior indication. Assessment of Cause: The problem appears to stem from a malfunctioning Idle Stop system, potentially related to the electrical or battery system. I understand that Honda has received multiple similar complaints from other Odyssey owners experiencing the same dangerous issue.

The forward collision prevention system engages the brakes when nothing/no one is in front of us. It will also engage the lane departure warning, which also engages the brakes, when construction zones remove the actual lane lines and temporary lines are put down. The car gets confused and brakes the car to a stop in the middle of a highway.

NHTSA #11724497

My van is braking when there are no cars or dangers in front of it. Sometimes there's a metal plate on the ground or speed bump when it brakes. Other times there's nothing in front. The car slams on the brakes and I cannot override it with the gas pedal. This puts my kids and I in danger of being rear-ended. This most commonly happens around 7:30am or 4pm when I'm taking kids to school or dropping off. I'm often in the carpool like or headed to the school when the car slams on the brakes. It's very frightening. The dealer cannot find an issue and cannot replicate the problem.

NHTSA #11689340

I was driving in light snowfall when several alerts notifying me that the radar sensor was not working. This is common in snow fall. Later I cleared off the radar unit cover (The Honda logo on the front of the car). The alerts remained. I took it to the dealer and they dubiously told me it was "damaged by snow". This is impossible. It was light snow. There was no collision or impact. This device should be durable. It has no moving parts. But Honda wants me to believe that it simply stopped working from driving in a light snow. They want $1300 to replace. How do I know the next one won't conk out after the first snowfall? These units should have a lifetime warranty with only exceptions for collisions or impact damage. If the unit is damaged by snowfall, it's clearly too fragile and should not be on the market. It's a HUGE safety concern that the vehicle's advertised safety systems can be toppled like a house of cards from one light snowfall.

NHTSA #11637656

Both door latches have failed, the first was at 3 years and the second at 5 years. When this happens the door cannot close all the way. This should be a recall as it’s a safety issue and also very costly to repair.

NHTSA #11727640

The power tailgate on my 2021 Honda Odyssey suddenly failed. A “power tailgate problem” warning appeared, and the tailgate became completely inoperable. It would not latch manually or automatically, even when applying force. The latch would spring back open, and no mechanical sound came from the door. Because the tailgate would not latch, the interior lights stayed on, and the vehicle continued to display “tailgate open” warnings. I could not secure the tailgate for driving, which created a safety hazard since the door could not be properly closed during travel. A few days later, both sliding doors also stopped functioning, and none of the powered doors (tailgate or sliding doors) would operate from the interior switches, exterior buttons, or key fob. The Honda service center inspected the vehicle and reported that the tailgate control module was corroded and had clear evidence of water damage. They stated that they would not replace the module until the vehicle was evaluated by a body shop because a water leak was likely present and would continue damaging components. The body shop later confirmed that water intrusion was entering through the upper left rear pillar, caused by a leak in the roof seam area. Water traveled into the rear side panel and damaged the tailgate control module and related electrical systems. Their findings were documented and also confirmed by my insurance inspector. Prior to the failure, there were no symptoms. The only warning occurred at the moment the system failed (“power tailgate problem”). The issue occurred without any impact, accident, or misuse. The defects caused multiple powered doors to become inoperable, which is a significant safety risk for both passengers and the driver. Based on publicly available information, this appears to be a recurring problem in 2018–2021 Honda Odyssey vehicles involving water leaks near the rear pillar leading to electrical control module failures.

Allegedly reported: 1 injury (as reported to NHTSA). NHTSA #11629558

Rear passenger side shock absorber snapped on a family road trip. Vehicle began to fishtail with every bump in the road leading to excursions very close to lane markings at times. Inspection by dealer not only confirmed the damage but also found older damage involving the right front control arm which also had to be replaced. Owner had noticed a rattle in the steering column before original new car warranty expired. Original dealer could not locate the source years ago. Problem completely vanished after the current control arm repair. Owner is concerned that had rear passenger side shock absorber and front swing arm completely failed at the same time that vehicle would have departed.the road surface at speed. Vehicle has 64,000 miles on it, relatively low, light mileage for a vehicle of this age. A Google search reveals many other owner of this same make and model year have experienced the same problems.

Approximately May 2023, while pulling away from stop light, heard loud pop (like gunshot inside vehicle) and vehicle shuddered/jolted. It feels almost like someone hit vehicle with sledgehammer. I looked underneath but no issues found. No bump in road was hit at the time. December 24th 2024, while moving at less then 5 mph, heard another loud pop and shudder/jolt. Someone sitting in the back thought that something fell on the vehicle. This time noticed that left rear tire was into wheel well with vehicle unloaded. After pulling wheel, found left rear coil spring broken in 2 places. Believe broke first in 23 and again in 24. At time, we were 1200 miles from home and needed to delay trip so Honda in Killeen TX could repair. Dealer service advisor stated they had never seen anything like that except from crash. June 19th 2025. On highway doing 70-75 mph when heard another loud pop and shudder. No pot hole or any significant bump hit. Stopped, pulled wheel, and found right rear spring broken. Honda dealership in Marysville OH unable to find new spring either through OEM or aftermarket. We have also been unable to find aftermarket or junkyards. Being told that there is a nationwide backorder and no eta for when replacment parts are going to start being available. So being forced to continue driving a vehicle that is unsafe. First this does not seem normal for springs just to randomly break. Second for a critical suspension component on a relatively new vehicle, why is manufacturer unable to proved parts. We are now 2 months into it being broken and can't even order replacment parts yet because Honda is not allowing orders to be placed.

NHTSA #11682656

I purchased a 2021 Honda Odyssey with 55,000 miles on it. At 57,000 miles with normal driving conditions, I heard a metal on metal noise on rear passenger side. Upon taking it to the mechanic, both rear springs were rusted & broken - essentially giving my van no rear suspension and making it very dangerous to drive. I had to find a new vehicle for my kids for a month and a half as there is no aftermarket part. Honda would not find the part for me and wanted me to work through the dealership, but I did not have the time as this is family vehicle that I need each day. I had an independent mechanic find a pair of springs from a junkyard & he confirmed that in his 40 years of servicing exclusively Hondas, he's never seen springs fail like this at this mileage. He expected a faulty part. I drove this vehicle multiple times thinking that it was safe & only something loose in the car. At any moment, the suspension could have failed & caused a serious accident. I do have the springs & have attached photos. Component has not been inspected by anyone other than myself & mechanic. No prior warnings or messages noting a problem.

While stopped at a stop light at an intersection in our 2021 Hond Odyssey, the idle auto off feature kicked in, and then as we let off the brake and went to hit the gas to move forward the car shut off completely. The car had to be restarted by applying the brake and pressing the start/stop ignition button. This is not the first time this has happened with this vehicle. This also happened a series of times in 2023 and Honda performed a series of software updates, replaced the battery, and replaced a sensor on the battery. However, now two years later the idle auto off issue occured again.

NHTSA #11681925

In stop and go highway traffic. Engine cut off when at a stop during "Ecoboost." Had to turn off car and restart. Was able to restart with no problem. Full tank of gas. Fresh oil. No error messages before and after

NHTSA #11653192

My Honda Odyssey is experiencing an issue where it intermittently fails to restart automatically after coming to a stop and engaging the idle stop feature. Despite following Honda's recommendations, which included applying Service Bulletin 23-008 (updating the PGM-FI Idle Stop Software) and replacing the battery, the problem persists. I've also had the vehicle inspected at two different dealerships, with no resolution. I discovered Service Bulletin 23-009 on your website, which directly addresses this exact issue and extends the warranty for the Ridgeline, Pilot, and Passport models. Given that my Odyssey shares the same engine, it's concerning that it's not included in this bulletin. I believe it's unfair that I'm being forced to pay dealership fees to diagnose and fix a safety issue that Honda has already acknowledged and addressed for other vehicles with the same engine. I urge you to reconsider the exclusion of the Odyssey from Service Bulletin 23-009 and provide a solution that doesn't burden owners with unnecessary costs.

NHTSA #11615252

2021 Odyssey EXL shuts off completely in traffic stop and go conditions. Happened three times in a 2 week period. Twice in city roads at traffic stop light and once in highway when the cars are in stop / go mode due to heavy traffic. Engine switches off completely and puts itself in "P" mode, all light comes on as if in accessory mode, radio switches off, all doors unlocked. To get going, the driver had to press brake pedal and start the car again (via Engine Start /Stop button). This issue started in the car at 43K miles. Never had any issue with mine before that. But it is scary especially the engine switch off in highway and traffic stop light.

NHTSA #11670208

This happened twice to us. While stopped at the red light the car suddenly shuts off and won’t start. We had to press and hold the start button for 5 seconds for the van to start. It appears that on both times the car just stalled.

What component or system failed or malfunctioned, and is it available for inspection upon request? The Auto Start/Stop function only works intermittently on our 2021 Honda Odyssey. Occasionally, when the Auto Start/Stop function does shut off the engine when the vehicle is at a complete stop, the engine fails to restart on its own. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? This malfunction occurs intermittently and without warning when the vehicle is at a complete stop in traffic. The vehicle cannot be driven under its own power in this condition, often leaving it disabled in a traffic lane with other vehicles stuck behind and/or passing by at normal travel speeds. As such, it endangers both the occupants of my vehicle and the other vehicles in the vicinity. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. My local Honda dealership acknowledged the problem and completed a PGM-FI software update. However, this update did not correct the issue, and Honda refuses to take financial responsibility for the repairs necessary to correct the problem. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The following timeline details my interactions with my local Honda dealership regarding this issue: 4/13/23 - The dealership inspected the vehicle and claimed the Auto Start/Stop system was "operating as designed"; 9/6/24 - The dealership completed a PGM-FI update as directed by a Honda product update campaign; 2/12/26 - The dealership inspected the vehicle, suggested battery replacement (which tested good on 3/3/26), and if still not corrected, advised replacement of the starter at my expense. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The problem has occurred without notice since purchase on 3/11/21.

After 4 attempts by the dealership to correct the issue, The windshield inside view mirror malfunctions when adjusted. The mirror dislocated and falls off and cannot be adjusted per driver viewing needs. There is a defective assembly and it inhibits driver view causing hazardous conditions that could cause accidents.

NHTSA #11556582

The interior rear view mirror falls off. Dealership is not fixing the problem after 4 visits. This creates a safety issue because the driver cannot view traffic that is behind the vehicle while driving in traffic

NHTSA #11555207

Completed a safety recall on Odyssey for a driver side mirror replacement and the mirror Honda provided and installed creates distorted images. It is nearly impossible to focus on traffic and safely change lanes. While driving in Chicago this weekend the mirror made it nearly impossible to merge with traffic or safely observe traffic entering on left side entrance ramps. Honda replaces the mirror a second time and the second mirror is also defective.

The contact owns a 2021 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 23V174000 (Visibility), and the vehicle was taken to the dealer, where the recall repair was completed; however, while driving from the dealer, the contact noticed that the replacement side-view mirrors displayed a distorted image. The vehicle was taken back to the dealer, who replaced the side-view mirrors; however, the failure recurred. The vehicle was taken back to the dealer a third time, and the side-view mirrors were replaced; however, the failure persisted. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 23,000.

NHTSA #11541871

I received a recall and call from the Honda dealership about a left and right side mirror recall, and they needed to be replaced. They were replaced with distorted blurry concave mirrors. Honda dealership was aware of this issue yet still installed them. After going back and getting them installed again, the mirror is still distorted. There has been no remedy or follow up.

NHTSA #11532898

The drivers side side-view mirror was vibrating for serval days making it impossible to see correctly and was very distracting. While waiting for a new one to come in, I was driving on the highway it came off and smashed into the door. It was still hanging by the wire and smashing into the door over and over till I could get it to the dealer. The dealer said they've have multiple customers with this same problem. When it happened I was very lucky no one was near me on the highway because I was so startled by the crash that I was swerving. Then I had to drive to the dealer without a working sideview mirror. Additionally, the entire door had to be repainted and the window replaced because they were damaged by the mirror.

NHTSA #11426112

Stopped at a stoplight, the engine will just die. It won't start again by pressing the gas peddle. It will require a few moments to try to restart it. It is very stressful and dangerous when people are waiting behind you. This is not safe. It won't happen every time but the few and far between are not good. We have replaced the battery and it sounds like other people have had this problem but no recall has been made to fix it.

NHTSA #11744223

When attempting to restart from the autostop function (i.e. the fuel economy function), the vehicle fails to restart successfully. This has happened on multiple occasions. It is not a battery problem and I have had the battery tested and even replaced (by Honda) and the problem has continued. The vehicle will stutter, stall or even completely shut down. This has happened when I have been at intersections and on busier roads or even in traffic on the highway. Its very concerning to me and seems extremely unsafe. No warning signs come in this scenario until the vehicle shuts down and the regular dash light engages indicating the engine is inoperable. I have today's date below but this has been happening consistently the last several months.

NHTSA #11686132

Vehicle shuts off completely when stopping at a light or sign. It does restart but you don't know it until you need to go. It is a safety concern!

After driving for 2 hrs in single digit temperatures I entered the on ramp to interstate freeway. I lost power, couldn’t accelerate further and the Check engine light was flashing. I pulled over on the 4 lane interstate, turned off my car and restarted. CEL went away. This is the 2nd time in 2 Winters this has occurred during cold weather. Both on exit/entrance ramps when trying to accelerate after turning with traffic behind me. This can only be reproduced in specific situations and diagnostics are not stored. Honda has a service bulletin on this issue 24-085. I feel it should be covered on all vehicles, regardless of warranty status due to the safety risk.

Leaking from the roof and tail gate caused the electronic control modules in the sliding door and rear gate to fail.

NHTSA #11730667

The contact owns a 2021 Honda Odyssey. The contact stated that while driving at various speeds, the "Passenger’s Sliding Door Failure" message was displayed on the instrument panel. The contact also stated that the rear passenger’s side sliding door failed to fully open upon entering or exiting the vehicle. The vehicle was taken to two dealers, Honda of Fort Myers (3550 Colonial Blvd, Fort Myers, FL 33966) and Coconut Point Honda (22240 S Tamiami Trail, Estero, FL 33928) and the contact was provided a diagnostic test fee to determine the cause of the failure, but the contact declined. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The vehicle was not repaired. The failure mileage was approximately 19,000.

the trunk door stopped working due to a leak from the rear left window seal causing the computer to become waterlogged the mechanic that fixed it said its a common issue with the Honda odyssey and should be recalled by Honda, I am therefore requesting the nhtsa to investigate this matter further so Honda should reimburse for the cost of the repair this issue can be a safety hazard in the event of a emergency egress from the trunk as it's not possible to open from the exterior and there was no prior warnings lamps or messages

NHTSA #11711166

The error message “Power Tailgate Problem” appeared on the dash. Following the error message, the power tailgate stopped working. It would not open or close with the remote, the button on the dash, or the button on the tailgate itself. I discovered water had been leaking in the tailgate and the trunk area of my vehicle as well as the back seat that was folded down in storage had gotten soaked. I took my van to the service center and they told me it was the seal above the door and that the leak had ruined the power module controlling the door. They repaired the issues. That was in April 2025. The same thing happened last week (January 2026). After looking into the error message and the tailgate problem, I’m finding that the door may open or close at any time on its own. The water in the electrical module may also start a fire. I have two small children and this van is our primary vehicle. I’ve reached out to the dealership from which I purchased the van, I reached out to a local Honda dealer and I contacted Honda customer service and no one is willing to fix this issue. I will be required to pay out of pocket again. I’m requesting a recall on this defect in design.

Drive side rear power door stopped working. Upon using handl to opperate as usual the door stopped only a few inches open. A gentle shove got it open and opperational. The next day it did the same thing this time refuding to eithe ropen completely or re-latch. My children were in the car with me on the way to school and the door could not be opened to let them out or closed to safely proceed on our route. We began diagnositcs and found that the door continued to be problematic; opening just enough to be unlatched but nor going further, opening only half way and locking in place, or openeing completely then refusing to close... the door being in manual mode or power mode makes no differnece. after complelty disasembling the door/panel to check calbles and motor, checking fuses etc we put it all back to gether and suddenly it worked fin for about a dozen tries. HOWEVER the passanger side rear door (perviously untouched) suddenly developed the same problem. Now both doors will not function in either power or manual mode and I am waiting on the dealership to look into possible computer issues.

The VSA modulator has repeatedly failed. When it fails, all of the safety systems report errors - air bags, ABS brakes, high beams, traction control, blind spot detection, parking sensors, etc. Additionally, the power sliding passenger doors and tailgate will not open, even manually. I have taken it into Honda dealerships on 3 separate occasions. On 6/14/21 (vehicle mileage 7,453) they cleared the error codes and reset the system and reported it was fixed. On 2/26/2022 (vehicle mileage 21,077) it happened again and they reported the VSA modulator as defective and replaced it under warranty. On 7/29/2022 (vehicle mileage 26,916) it happened again. This time the dealership disconnected and reconnected the VSA modulator and it decided it was fixed. At the time of the issue I was driving the van at approximately 30 mph on flat streets through my town. I've expressed my concerns that this defect renders the vehicle extremely unsafe. Over the past two weeks I've contacted Honda Corporate repeatedly requesting further repairs or assurances that this error would not occur again and have been passed around to case managers' voice mailboxes and have been unable to speak to anyone about my concerns. While no injury or crash has occurred yet, I am concerned that this if this occurs again, myself or my family could be hurt.

NHTSA #11477648

After a slight rain, the error of Radar Obstructed is being displayed. Can’t get this error removed or fixed. After searching more I found out that: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, i.e., the placement of the radar behind the large, thick plastic H emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a RECALL that permanently addresses the problem.

NHTSA #11611850

I am writing to urgently bring to your attention a critical issue plaguing the driver assist systems in Honda Odyssey 2018+ vehicles. Despite meticulous maintenance and adherence to manufacturer guidelines, I have encountered a persistent and alarming problem that appears to affect numerous other vehicle owners, as evidenced by online forums and discussions. The issue initially arose during a rainstorm, where I received a warning message stating, "Some Driver Assist Systems Cannot Operate: Radar Obstructed." Despite the weather clearing and thorough cleaning of both the sensors and the windshield camera, the warning persisted. Subsequently, a series of related problems emerged, including: Illumination of the BRAKE SYSTEM LIGHT Malfunctioning adaptive cruise control Faulty collision mitigation system Inoperative road departure mitigation system These errors not only pose a significant safety risk to myself and others on the road but also indicate a systemic issue with the vehicle's safety systems. As my vehicle is just past the three-year mark and out of warranty, I am apprehensive about incurring substantial costs for dealership repairs, especially considering the widespread nature of these complaints among Honda Odyssey owners. Extensive research reveals that I am not alone in experiencing these issues. Multiple reports and discussions online highlight similar complaints from other Honda Odyssey 2018+ owners, particularly following exposure to adverse weather conditions. Therefore, I implore the National Highway Traffic Safety Administration to conduct a thorough investigation into this matter. It is crucial to identify the underlying cause of these recurring issues and hold the manufacturer accountable for any design flaws or defects contributing to the malfunction of critical safety systems. Furthermore, I urge NHTSA to prioritize public safety and take immediate action to ensure affected vehicles are promptly recalled or repaired to prevent further incident

NHTSA #11582551

1. While I was driving on the freeway, my radio turned off and my car put itself into NEUTRAL! I was able to safely pull over and put it back in drive. Note: This incident happened after 2 months of weird electrical things happening to the car, such as the radio turning on after the car had been turned off, car not starting, sliding doors losing power when they are halfway closed, coming to a stop and putting the car in park then the car completely loses all power/interior lights, the car turning off while stopped at a light and more... 2. Had there been more traffic I would have been in major danger. I could have easily been rear-ended or hit someone in the process of trying to get off of the freeway. It could have caused a multiple car collision. Grateful my children were not in the car at the time of the incident. 3. The car has been inspected by Spreen Honda multiple times and by an independent Honda mechanic. Spreen Honda has not been able to reproduce the problem. They won't do anything besides hook it up to the computer, and since there are no codes present "there is nothing they can do". The independent mechanic said they'd never seen anything like this. When I reported the incident to Honda America, they recommended I should continue taking the car to the dealership, which makes no sense as the dealership does not actually attempt to diagnose the problem if there is no code. 4. The manufacturer has not inspected the vehicle. When I reported this to Honda America they encouraged me to continue working with the dealership service department only. They don't take information from 3rd party service providers. This is completely unacceptable. 5. Right before the car shifted to neutral, the radio turned off and the dash lit up orange.

NHTSA #11604614

1. Incident: I was driving and stopped at a red light, took my foot off of the brake and the car completely died, leaving me stranded at the intersection. The car started back up after 4 minutes. Note: This incident happened after 2 months of weird electrical things happening to the car, such as the radio turning on after the car had been turned off, car not starting, sliding doors losing power when they are halfway closed, coming to a stop and putting the car in park then the car completely loses all power/interior lights, and more... 2. My safety was put at risk by having a non-functioning car in the middle of the road. Someone could have rear-ended me. Also, it was over 100 degrees outside which added to the panic I was feeling. 3. The car has been inspected by Spreen Honda multiple times and by an independent Honda mechanic. Spreen Honda has not been able to reproduce the problem. They won't do anything besides hook it up to the computer, and since there are no codes present "there is nothing they can do". The independent mechanic said they'd never seen anything like this. 4. The manufacturer has not inspected the vehicle. When I reported this to Honda America they encouraged me to continue working with the dealer. This is completely unacceptable. 5. Right before the power went out the dash lit up with every warning lamp for maybe 5 seconds.

While driving the car suddenly lost power and display warning indicated that you should steer to a safe location and turn off the vehicle. Turned the vehicle on to put it into neutral (would not go into neutral unless the engine was running) to get it on the wrecker. Smoke started coming from the engine compartment. Called Honda dealership to ask how to put the vehicle in neutral without turning on the engine and was told there was no bypass. Vehicle was taken into dealership for repairs and was told the air conditioning compressor and compressor clutch had failed. Drive belt was also damaged due to failure. Compressor, clutch, condenser, and drive belt all require replacement.

NHTSA #11544921

ON REACHING THE EXIT OF A TUNNEL CAR WASH, THE VAN WOULD NOT SHIFT FROM NEUTRAL TO DRIVE. THE INSTRUMENT CLUSTER DISPLAYED A MESSAGE THAT, IN ORDER TO SHIFT INTO DRIVE, I HAD TO DEPRESS THE BRAKE PEDAL. THIS HAS HAPPENED TWICE, AND THAT'S CLEARLY A DANGEROUS THING TO DO IN A TUNNEL CAR WASH. I CAN'T REPLICATE THE ISSUE IF I PUT THE VAN INTO NEUTRAL AND COAST DOWN OUR STREET (ABOUT 1200 FEET).

HI, A driver of a 2021 Honda odyssey EX-L struck and ran over my 6 yr old child, driver was unable to see the child sitting on the driveway ground from his view, If this Honda odyssey EX-L would have Parking Sensors this accident would be avoided. I urge you to request Honda to install this feature in all Honda Odyssey models as this feature can save lives. Thanks

Allegedly reported: 1 injury (as reported to NHTSA). NHTSA #11537437

I was driving on I-270 highway in active HOV lane and had to stop because of traffic. The car stopped the engine as it usually does by "Auto Idle Stop" system but failed to start it back when I needed to continue driving. I noticed that the battery light blinked on the dashboard when it tried to re-start the engine. As a result I was in active HOV lane with quickly approaching traffic from behind. We all (me, my wife and 2 kids) were scared. I called 911 immediately for help. This all could end up with a crash and injuries. While calling 911 I was trying to restart the car by pressing the button to turn the car off and on. About 3 attempts failed when a few minutes later the engine started and we continued the drive. This was the worst nightmare to stuck on a highway. Luckily nothing happened but it definitely could. This is a major concern for me.

I hear a popping/crackling noise from the speakers then I get complete network loss for my backup camera, my dvd player, my clock, maps etc.System does a report after 5+ minutes. Message displayed before everything goes black is Network Connection Lost and MOST Net Off. This issue is ongoing and seems to happen now every day sometimes multiple times in a driving session. It just started about 2 weeks ago. There is an active recall for this exact issue for 2021 Honda Odysseys but my VIN does not seem to be included.

NHTSA #11689851

Can has been making a popping noise that can be felt in the steering wheel for 2 years. Honda has told me nothing was wrong after taking it in 4 times. Now my car keeps stalling at lights, sometimes it takes a while to get it to restart, and they can not figure out why. They keep saying the battery is fine and diagnostics finds nothing.

NHTSA #11683344

Vehicle applied brakes for no reason. Lost ability to see reverse camera during backing up. Half of the instrument cluster went dim to become barely visible. Radio screen freezes randomly. Engine cuts out or shudders intermittently.

2021 Odyssey EXL the Electric parking brake 'issue' warning comes on while driving and collision mitigation warning / lane assist switches off and flashes in console; when this happens the car continues to run but the dashboard warning lights comes up for Parking brake / Collision Warning and or Lane assist. It gets cleared after I turn on/off the car couple of times and drive for approximately 5 miles. Those features had to be turned on manually, once the car is in parked mode, again. The issue started in the car at around 48K miles. Never had any issue with it before that.

NHTSA #11670202

It started that all the sensor in our car started to go off. We were told we had a bad battery, even thought we had replaced it new just last year. Once we had the battery checked and alternator. The sensors started to act up again, out tail gate started to malfunction. Wouldn’t automatically close. A few weeks ago driving down the road the tail gate opened and the anti theft system started going off while the car was running and still going. Come to find out there is a water leak in the rear that has gotten into the rear fuse box and has cause substantial corrosion. The latch to the tail gate is broken. Honda is telling us our extended warranty doesn’t cover any of this, even though it is common knowledge, that the water leak is a known problem from 2018-2021. We just found out a few days ago.

The contact owns a 2021 Honda Odyssey. While the contact’s wife was driving approximately 70 MPH, the vehicle began to lose automotive power with several unknown warning lights illuminated. The vehicle was driven to the shoulder of the roadway before stalling. The vehicle was unable to be restarted and was later towed to the local dealer. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 72,000.

NHTSA #11629582

The contact owns a 2021 Honda Odyssey. The contact stated that on one occasion while the vehicle was parked, the rear hatch failed to open. Additionally, the contact stated that while driving at approximately 35 MPH, the rear hatch opened inadvertently. The contact pulled over to the side of the road where the door was closed but failed to securely latch. The vehicle was taken to a dealer where it was diagnosed and determined that condensation had leaked into to the driver’s side of the gate and damaged the rear gate control unit. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 46,500.

A few weeks ago, the car I was driving steered itself dangerously close to a pedestrian in the breakdown lane. I was driving my wife’s car which I drive infrequently. This model has a lane-keeping function which steers you back into your lane if you veer. I was rounding a bend in the right lane on a highway as a man appeared on the edge of my lane, changing a tire, partially in the roadway. I was pointed away from him so I let the car coast out of his way but the car literally turned the wheel and fought me as I tried to veer left out of the man’s way. It all happened in less than a one or two seconds. Had I used the turn signal the system would have temporarily disabled itself. I shared this story on Facebook with my friends and several friends reported nearly identical issues with lane keeping driving them towards a hazard.

After having the Honda Dealership perform an oil change and software update 23-008 (updating the Auto Idle Stop Software) last week, my engine stalled while at a busy intersection (PA turnpike/70 junction) during a road trip. At the long stop light the auto idle function engaged and the engine turned off. When the stop light turned green and I lifted my foot off the brake and pressed the gas the engine shut down and automatically went into Park. I had to press the start/stop button to fully turn off then turn back on the car to get the engine to restart. This is with a giant semitruck honking right behind me. The auto idle feature does not work. It sounds terrible every time the engine restarts after it has been engaged. There really should be an option to allow users to permanently disable it, and not have to remember to turn it off every time they start the car--terrible user experience.

NHTSA #11621957

After the PGM-FI update was put into our car, the engine cuts out entirely while at stop lights and will not wake back up. The Honda dealership is saying that there is nothing they can do.

The third row seat latching mechanism will not lock the seat into place on the floor. We had a child who was sitting in the seat and the seat flipped backward. It is the left side seat in the third row. It appears the mechanism inside the seat that secures to the floorboard is missing or broke.

A recall has been issued on my vehicle since February. It is now almost May and when I call Honda about the recall they tell me that they do not have the solution as of yet.

Recall for driver side view mirror completed. However the replacement mirror is distorted and causes blurred, wavy, double images. This replacement mirror needs to be addressed as soon as possible since proper representation of objects is distorted and poses a high safety concern. This issue has been reported in several forums as well.

NHTSA #11569641

Rear view mirror on the windshield has a factory defect. It falls off and causes hazardous conditions. I backed into a parked and unoccupied vehicle. It was dark, the warning beeper did not sound until I hit the vehicle. The dealership has attempted to fix the issue 3 times, the item is ordered to fix the mirror. I have reported this issue to the NHSTA twice. This is my second update after the initial report. The sales manager, Bobby, (cell#336-740-4273), says that he is aware that other Honda vehicles have had this problem with the mirror.

NHTSA #11556927

Once the cruise control is set, it consistently drops below the set speed and surges back up or over the set speed. Set on 62, it drops to 59 or 60, then surges back up to 62 or 63. This happens on perfectly flat roads with no traffic in front or beside the car. The dealership tried to tell me that the camera for the adaptive cruise might be seeing things in its peripheral vision area, but there is nothing there, the shoulder of the road is wide and free of obstacles. I've owned many other brands of vehicle, and never had this trouble with the cruise control on any of them. This is also a safety issue because sometimes it just randomly slows down or speeds up when there are cars behind you or beside you.

NHTSA #11540905

I have a 2021 modely Honda Odyssey Elite (purchased in November 2020). This car has 14,000 miles on it as of July 29, 2022. When accelerating from a complete stop or accelerating after slowing down, upon depressing the accelerator pedal the car simply refuses to accelerate for a second or two and simply coasts due to momentum and then after a while accelerates hard causing a sudden jerky take off. This might not seem like a big issue on its face, but that delay has almost caused me to get hit by the oncoming traffic especially when making a right turn or when changing lanes. I have 3 small kids (one of them a baby, and a five year old) and this is a precarious situation to be in. Also, this happens intermittent in all weather conditions (be it cold or warm or hot doesn't matter) and we don't know when this will happen and cannot replicate consistently on demand. Just happens maybe every few days but is more consistently happening. There are several similar complaints from Odyssey owners, NHTSA, you are our only recourse to this as I feel this is a model wide problem which needs to be addressed by Honda from the factory with a recall. Thank You!

NHTSA #11476449

Honda Odyssey 2021 has major safety issues – the van starts engine on itself, shuts the engine on itself, tail lights are on when the engine is running, the knob for the lights on the turn signal handle was in OFF position when the van was observed starting, running and shutting engine on itself – for no reason. In all occasions key fobs were untouched. Once Honda Odyssey was observed with the engine starting and shutting on itself when both of the key fobs were in 10 miles distance from the vehicle. Brought twice to the dealer, cannot fix it. Contacted Honda on 2/17/22 informed about the problem. Called Honda on 2/21/22 to check on the case, was told that will assign a manager to review this safety concern, but it may take two weeks, possibly two month or maybe more, depending how busy they are. 8 days have passed, no response yet from Honda. I am concerned that it may shut the engine on its own while driving.

Back up sensors stopped working 4 months after purchasing a brand new vehicle. Also the side sensor just randomly lights up when there’s nothing around or the Brake light pops up

NHTSA #11518007

While driving in highway construction zones the car's lane departure system attempted to steer the car along lane markings set before the construction zone was established. In several instances this caused my car to steer, contrary to my steering input, towards Jersey barriers and dangerously close to a collision. The car's collision warning and automatic braking systems then engaged and applied the brakes regardless of following traffic. After the first instance, luckily in light traffic, I became aware of this issue and aware of how to quickly defeat these safety systems. After several additional instances, some in traffic at highway speed, I determined the lane departure system was more dangerous than helpful and I suspended it by a simple dashboard procedure. I am now able to negotiate construction zones without issue.

HI THE VEHICLE SHOWS SPEED LIMIT OF 70 IN 25 OR 40MPH ZONES. THE VEHICLES SYSTEM KEEPS GOING OFFLINE EMERGENCY BRAKING AND COLLISION. EVERY TIME I TAKE TO HONDA DEALER I AM BEING TOLD TO GO SEE WHERE THE CAR WAS PURCHASED AND THEY CAN'T FIND A ISSUE.
