Acura Mdx 2022: Retiros, Quejas y Ley de Limón de California

I accelerated from a complete stop and heard a loud bang from the transmission at 10 mph. No warning lights came on, but car now only operating in front wheel drive mode instead of AWD. Front wheels will spin under hard accelerating confirming loss of power to rear wheels. Local mechanic confirmed issue by putting vehicle on lift and showing rear drive shaft spins freely. This is a know issues for this vehicle and NHTSA has open investigation into splines connecting transmission to transfer case sheering off under load. Investigation Number 11712885.. This should result in a recall for Acura at no cost to customer.

I was driving down the highway and a passerby notified me that my car was smoking. There were no indicators on the car notifying me of any issue. We pulled over and saw the car was leaking oil heavily. When taken to the dealership, they notified us that there was a leak in the transfer/transmission case and the whole transfer case would need to be replaced. The car is well maintained and had been recently serviced and no issues came up. It's very scary that there were no indicators of issues on the dashboard and my family and I could have been endangered while driving on our family vacation. Acura knows of this transfer case issue and has had to replace many of them in recent MDXs. This is a safety issue that needs to be investigated immediately.

I am submitting this complaint regarding my 2022 Acura MDX Advance, currently with 71,007 miles. After completing the standard transmission fluid service around the 60,000-mile maintenance interval, I began noticing abnormal drivetrain/transmission behavior that was not present before. At times, the vehicle feels as if the transmission is slipping, hesitating, or failing to transfer power smoothly. Acceleration can feel delayed, uneven, or weaker than normal, and on some occasions the vehicle seems to surge or accelerate slightly in a way that does not feel consistent with normal pedal input. This is a safety concern because the vehicle may not respond predictably when accelerating from a stop, merging, passing, or driving at highway speeds. A delay, slip, surge, or loss of expected acceleration could increase the risk of a crash, especially in traffic. The symptoms appear to involve the transmission, drivetrain, torque converter, transfer case, software calibration, or related components, but I am requesting a proper investigation to determine the actual cause. My concern is that this issue could worsen or affect other 2022 Acura MDX vehicles if it reflects a broader defect. I am requesting that NHTSA document this complaint and review whether 2022 Acura MDX models may have a safety-related issue that can cause slipping, hesitation, surging, delayed acceleration, or loss of expected power after normal maintenance. Acura should evaluate whether owners need inspection, repair, software updates, or other corrective action.

Issues with the sunroof frame. I've notice popping from the car roof Acura is aware of this issue they've put out a bulletin but only covering cars that have less than 50k miles and are under 4 years old. After researching I see a lot of people are having similar issues where the screws come lose and the sunroof frame breaks causing some sunroof to shatter.

My power steering has went out while I was driving at least 4 times in the past year. I contacted the dealer each time they say they've never heard of this happening. I took it in they couldn't replicate the issue so no fix although the codes were stored. All the warning lights came on braking, steering, lane departure, lane keeping, parking etc. It happened again today each time by 1 year old was in the car. They say if it happens while the dealership is open bring it. But it's always happened after hours. I was able to stop car each time turn off then back on and its fine. I even replaced the battery last year thinking that would fix the issue and it didn't. I'm not sure what else to do but I don't feel safe driving the car with my baby in it anymore. I deleted the pictures by mistake but I found where a rdx had the same issue I'll attach the codes that came up.

Incident happened on 2-JUN-2025 While driving home from work at around 45-50 mph, all of a sudden, every warning light on the dashboard illuminated, displaying various messages such as “Brake System Failure - See Your Dealer,” “Power Steering Failure - See Your Dealer,” “Road Departure Mitigation System Problem - See Your Dealer,” “Lane Keeping Assist System Problem - See Your Dealer,” and “Collision Mitigation Braking System Problem - See Your Dealer,” among others. The power steering became extremely difficult to turn, almost as if it had locked up, while the brakes were also stiff but seemed to function. The steering wheel completely locked, and I was fortunate enough to maneuver the car to the side of the road by forcing it. After turning the car off and on about three times, everything finally returned to normal on the third attempt. I immediately contacted the Acura dealership to report the issue and scheduled an appointment, feeling apprehensive about driving on the highway, fearing the problem might recur. After dropping off the vehicle, the Acura dealership diagnosed the issue, as a “Power Steering Rack/gearbox malfunction. Luckily it was covered under the extended warranty. Q.1) The components that failed or malfunctioned include the brake system, power steering system, road departure mitigation system, lane keeping assist system, and collision mitigation braking system. These components should be available for inspection upon request at the dealership where I reported the issue. Q.2) My safety and the safety of others were significantly at risk due to the sudden failure of multiple critical systems. The power steering became extremely difficult to operate, and the steering wheel locked up, making it challenging to control the vehicle. This could have resulted in an accident. Q.3) Yes, the problem was confirmed by the Acura dealership after I reported the issue and dropped off the vehicle for inspection. They diagnosed the malfunction.

Asymmetrical wear on the front brakes. The outer pad wears out completely while the inner pad( with the brake wear sensor) shows almost no wear. The dealer (Park Place Acura, Plano Texas) brought this to my attention on November 3, 2025 saying only the front pads needed replacing but did not disclose the asymmetrical wear. I took the vehicle back to the Dealer January 15, 2026 for repair after discovering the asymmetrical pad wear and pointed that out to them. The brakes can completely wear to the backing plate on the outer pad while showing no wear issues with the brake sensor on the inner pad. This condition creates an unpredictable and uneven braking response that constitutes a safety defect, as the brake wear indicator system fails to alert the driver to actual brake wear on the outer pad. The brake wear sensor is designed assuming symmetrical pad wear. When wear is asymmetrical, the sensor fails to trigger a warning, leaving the driver unaware of a dangerous condition. The dealer has finally replaced the pads and rotors, symptoms of the problem but, has not addressed the underlying cause of the problem...the calipers. I have received the vehicle back from the dealer but did not sign a release and the issue remains open. The vehicle currently has approximately 29,400 miles. I have taken this issue to Acura corporate(Honda Motor Company) and they have it under review but keep delaying with no confirmed resolution. I sent a certified letter to American Honda Motor Company, Acura client relations on February 3, 2026 and they signed for it on February 11, 2026 and contacted me by email on March 11,2026. Acura took 28 days to respond to my certified letter and has provided no resolution timeline since.The vehicle was under the original manufacturers warranty at the time of this issue and notification.

Brake system warning light comes on and says reduced braking take to dealer. Auto hold brakes don't always hold. Rear brakes non stop squeal and grab un predictably. I am unsure when and if the brakes will work in the rear. The loud noise from the rear squeal has caused others in traffic to flag me down and warn me something is wrong. The noise is also made it impossible to have my Autistic nephew in the vehicle with me as it triggers episodes and scares him. I have asked the dealer to please repair the rear brakes several times. They refused and instead replaced the front brakes, then admitted it is the rear brakes but refused to repair them. Honda of America also refuses to repair rear brakes. Based upon false statements on the work order the statement from the dealer is the rear brakes on the MDX are supposed to be like this. This vehicle has issues with the warning light while stopped and moving, and the noise and unsafe braking is at all speeding from 1-60 mph. Forward and reverse is malfunctions. I asked Honda America to repair which they won't then I ask them is the official statement these brakes are okay and safe as is and they will not say that either. I have driven similar models of this vehicle and it does not do the same thing, no noise, or warning lights, and the brakes preform safely and consistently. Mine do not. Honda of America does not want to repair the brakes under the warranty. They also incorrectly stated on repair statement that humidity and car washes can make the brakes do this. I have been in northern non humid states during winter and never use a car wash. They just use this as an attempt to not repair the brakes.

I have experienced several incidents where I am driving on open road with no obstructions in front of my vehicle and the collision braking feature suddenly engages. This has led to vehicles behind me almost rear ending my car due to the unexpected, strong, and abrupt nature of the braking on open road.

NHTSA #11678638

On at least 5 occasions my automatic braking system has engaged when there were no obstacles in front of the vehicle. This has happened when driving at higher speeds (approx. 50 mph) on Lake Shore Drive in the city of Chicago as well at speeds below 30 mph along residential streets in my neighborhood. When I mentioned this to the dealership, I was told that perhaps there was interference from metal guardrails during the higher speed triggering of the brakes. The residential area incidents have occurred when there was no cars or pedestrians anywhere on the street. I am worried that I will be rear ended because the braking is occurring unexpectedly with clear roads ahead.

NHTSA #11534952

As I was approaching an intersection the car engaged the brakes without reason and I was unable to drive the car. It forced the car to stop in the middle of a busy intersection. Thankfully no one else was around or behind my car, but this could have resulted in a very bad accident resulting in my being rear ended at high speeds. The car had 4 passengers, including 2 children in car seats. I am open to the car being inspected. I plan to take it to the dealership for this reason.

MDX back sunroof drains cracked causing the car to flood. The water came into the back hatch and also damaged the amp to the speaker system. All of the Carpet had to be pulled out of the car. This car is only four years old. Luckily, I caught it because my whole back hatch was full of water, but this could’ve caused mold and serious health problems. I have found 100’s of reviews on many different online portals stating this is a common problem with a 22 to 25 MDX. I just bought this car a year and a half ago used and I have to now put another $5500 into it. I did buy the extended warranty, but they are saying this is not included in that. From what I’m seeing on Acura MDX group pages this is an extremely common problem that’s costing people a lot of money. There is no way apart should be breaking this easily in a car that’s four years old, especially a luxury car such as the MDX advance.

I am writing to report a severe manufacturing defect and safety hazard on my vehicle. The interior door panel trim has completely delaminated and peeled away from the door structure, creating an exposed, razor-sharp edge right near the door handle/window switches. This is a major safety hazard ("Safety Hazard") that poses a severe laceration risk ("Severe Laceration Risk") to any passenger or child attempting to open the door or touch the door panel. I have clear photo documentation of this sharp metal/plastic piece protruding dangerously out. I would like to request Acura Client Relations to look into this manufacturing defect immediately and provide a resolution/goodwill repair before a severe injury occurs. Please contact me via email to review the photos. Thank you.

My 2022 Acura MDX A-Spec developed an electrical problem where I heard an extremely loud pop come from the stereo system before it stopped working and then the infotainment screen stopped working as well. I took it to the dealer who determined that a water leak in the sunroof drain plug caused the interior of the vehicle to become saturated with water and cause corrosion to electrical bundles. By searching the internet, I found that this was a known manufacturer’s defect with this specific model that had been made known to the dealership and they did nothing about it. Having an electrical problem could have put us at risk had things stopped working at an inopportune time on the highway or caused a malfunction at a critical time while driving. I submitted a request to Acura for an extended warranty of this problem, but that request was denied. They said that there had been an extended warranty for this issue, but that it had expired somewhere between March 2025 (when my normal warranty expired) and October 2025 (when I took it to the dealership for an evaluation of this problem). Acura wouldn’t say when that was, but I was surprised that they were of no help. As I mentioned, this is a known manufacturer’s defect that should have been checked per my normal maintenance visits, but it was ignored until it became an actual problem. They certainly could have been more proactive and it would have saved us a lot of time and expense.

“fuel door stuck,” “no manual override,” “can’t refuel.” As per Acura manual there is way to open a gas/fuel door/cap/lid when actual way of opening through electronically fails due actuators or some other reasons. There is a manual release pull cable behind a removable access panel in the driver’s side of the cargo area trim, near or behind the wheel well lining. manual fuel door release is inside the trunk (cargo area) in case the electronic fuel door release fails.

The car threw several warning lights on the dash. The main indicator was that there was a problem with the air suspension: "Adaptative air suspension problem. Please see your dealer." The left airbag on the suspension then popped, rendering the car undriveable as the compressor would constantly blow air to try to inflate the airbag. The car was repaired at an independent facility at the cost of $2900.00 to replace the suspension airbag and the height sensor, as well as recalibrating ADAS. The car had 66k miles at the time of the incident.

We purchased the vehicle on April 2nd. The front left strut airbag burst while we were driving at 23 miles an hour. Thankfully were weren't going fast when the failure occurred. I would imagine that at highway speeds this could greatly impact your driving ability as the front left of the car dropped down about 6 inches. The dealer currently has the part on backorder but has yet to attempt a repair. Our vehicle has been out of commission for 26 days. We got about 15 warning lights and parked in our driveway as we happened to be near our home when the strut broke. We had the vehicle towed to the nearest Acura dealership.

I was driving my car on the interstate and momentarily stopped due to traffic congestion. My engine idle stop feature was on and engaged as expected for the short stop, but the vehicle then stalled when I attempted to drive. There seemed to be an electrical issue with various lights coming on the dash to indicate a problem. I could not get the car to restart and was stuck in the left lane with cars then going around my stalled vehicle. I called 911 for help after I could not restart the car after 3 attempts. After approximately 5 minutes, I pressed the ignition button again, and this time my car was able to restart and drive normally so that I could exit the highway.

NHTSA #11678636

The engine suddenly shut off when the vehicle was waiting for traffic light and at full stop. The vehicle would not restart after multiple attempts and had to be towed to dealership. Mechanic at the dealership said the "Idle Stop" feature can drain the battery quickly and had to replace a new battery. We consider this a reportable safety hazard and a potential design defect because 1. The "Idle Stop" feature is turned on by default, though it can be manually turned off. 2. The incident occurred in a very abrupt and unpredictable fashion. The vehicle was started normally about 30-40 minutes before the incidents and has been driven normally in a typical city traffic condition till the incidents occurred. During this period, the computer system did not give off any warning related to a total battery failure.

the last 3 times we had very insignificant snow accumulation, my vehicle dashboard lit up with 6 different warnings, some audible. when you look up the info on them it says the car cannot steer, break, will roll on a hill etc. One warning advises to remove all flammables from the car. I was very nervous and almost towed the car but since I was a mile from home I drove it and brought it to the dealer at 0730 next day. they said nothing was wrong. snow or dirt probably got behind sensor. It has happened two more times in the next 10 days. I keep taking off work and nothing is wrong. The issue is when this happens you cannot change the vehicle to snow mode to drive. this is a safety feature as well as the flashing "brake" warning and audible alarm. I have a [XXX] and [XXX] driver and they do not want to operate this vehicle. Both times it happened again, I took it to the car wash and cleaned every visible camera and sensor to no avail. I am taking it back to the dealer again this Friday but if nothing is wrong with any of these systems then there is something wrong with the cameras because how can someone operate AWD and snow mode when there are these false warnings and how do you know if they aren't false. I don't want to assume each time it's not but 3 times in 10 days and missing work, etc. Plus I am very nervous driving it like this. I reported it to Acura- they said there were no recalls. would not provide info if they have prior complaints. On google, I have found numerous complaints about this.

Observation 1: Lane-keeping assistance is unreliable and the results of its operation are highly variable. In optimum conditions (daylight, wide lanes which are clearly marked; good contract between lane markings & pavement; no more than very gentle, wide-radius curves), this feature will do one of three things when the vehicle starts to drift from the middle of the lane: (1) the feature will gently steer the vehicle back to the desired position, (2) the feature will exhibit a warning by vibrating the steering wheel and allow the vehicle to change lanes or (3) fail and do nothing -- without any warning whatsoever. One never knows how the car will react but it certainly cannot be trusted. Observation 2: When driving in light traffic or no traffic conditions the vehicle will occasionally brake aggressively. This was observed to occur on multiple occasions. Two situational examples which have been observed several times: (1) four lane roadway inside city limits; speed: 40mph; I was gently braking to stop behind a vehicle stopped at a traffic light; car applied brakes rapidly nearly causing a rear-end crash as the vehicle behind me did not anticipate the Acura's action. (Judging from the hand signal I received I believe the driver of the vehicle behind me though I was administering a "brake test" -- a common precursor to "road rage.") (2) driving on a two lane country road at 50-55MPH; no other traffic within hundreds of feet in any direction; vehicle brakes rapidly for no apparent reason; my attempt to accelerate and over-ride the "safety feature" was unsuccessful -- eventually the Acura stopped this action and I was able to resume desired speed. Important to note: At no time during these incidents did braking occur to avoid a crash or minimize damage. These were uncommanded operations that actually increased the probability of a crash. These events occurred between 11/21 and 03/22.

I recently (11/9/23) took my 2022 MDX (22,00 miles) to the local Acura dealer for an issue with my windshield washers not working. They diagnosed the problem as the washer jets were clogged and said the replacement parts were on back order and they were not given a time when they would arrive. I am concerned that currently my vehicle is unsafe to drive during inclement weather conditions-- i.e. slush, muddy roads, etc. Acura customer service has not been able to provide any ETA on this issue

On April 17 2026 while driving my 2022 Acura MDX at very low speed in a parking lot, the vehicle suddenly accelerated forward without warning and surged into bushes before I could stop it. I did not mistake the gas for the brake pedal. This felt like a sudden unintended acceleration event. I was preparing to park in a stall and the vehicle lunged forward unexpectedly. I applied the brake, but the braking did not immediately stop the forward surge. Earlier, I experienced another unusual event in which the vehicle abruptly auto-braked, jerked, and made a warning sound while I was slowing for a red light. I noticed the car felt as if it was surging a bit on residential streets and was about to mention it during the next service. This incident has caused me to lose confidence in the safety of the vehicle. I contacted Niello Acura who has been very cooperative. I was told the issue would need to be duplicated or that they could only inspect it if a code had been stored once the car is repaired. The car is currently being repaired with close to 7,000 in front end damage. I am reporting this because a sudden unintended acceleration presents a serious safety risk and could easily have caused a more severe crash or injury. I did research on this issue and have found various reports of unintended accelerations in the Acura MDX forums from various years but was unable to find any recalls or outcomes with these reports My concern is this will be dismissed as "operator error" or a phantom incident that cannot be reproduced.

Please add me to the compliant pool. My transfer case/transmission went out - 2022, 80,000 miles. March 6, 2026 NHTSA CAMPAIGN NUMBER: DP26001 OPEN INVESTIGATION All wheel drive allegation NHTSA Action Number: DP26001 Components: POWER TRAIN Opened From: March 6, 2026 – Present Summary The Office of Defects Investigation (ODI) received a Petition dated January 9, 2026, requesting an investigation into the loss of the optional all-wheel drive capability in model year (MY) 2021-2023 Acura TLX and MY 2022-2023 Acura MDX vehicles. The Petition contends that the interfacing splines between the transmission and the rear wheel drive power take off unit are failing. Failure of these splines prevents the transfer of drive power to the rear axle, making the vehicle front wheel drive only. The Petition further alleges that this failure results in a reduction of vehicle directional control. The Petitioner cites 48 complaints received by ODI alleging the same failure. ODI will evaluate these complaints to determine if they are related to the failure cited in the Petition and will conduct a technical review under 49 CFR Part 552. This Defect Petition is being opened to evaluate whether to grant or deny the Petition. The Petition can be viewed at NHTSA.gov under NHTSA Number 11712885.

MDX Type S with 63k miles. After performing diagnostic check there were several fault codes related to the vehicle's suspension system. Upon inspection, they identified issues with the ride height (stroke) sensors and wiring. The right rear, left rear, and right front sensors are affected. The right rear sensor has a broken pin, and part of that pin is stuck in the wiring connector. The left rear sensor also has a pin that is corroded. Additionally, the main wiring harness along the floor is corroded. This is due to poor location of wire harness in the Type S, and corrosion was due to salt exposure from icy roads. Dealership confirmed this was a known issue and had about a dozen of these replacements in the last few months.

NHTSA #11726051

I am filing a complaint regarding my 2022 Acura MDX Type S with approximately 70,700 miles. The vehicle developed a suspension system warning, and upon inspection by an Acura dealership, I was informed that the suspension stroke sensor and floor wiring harness are corroded and require replacement. I was quoted approximately $12,000 for the repair. This failure is extremely concerning because the vehicle is only a few years old and this type of corrosion affecting a major wiring harness should not occur under normal operating conditions. The affected components are part of the suspension system, which directly impacts vehicle handling and safety. Due to the failure, the suspension system may not function properly, potentially affecting ride height, stability, and overall control of the vehicle. This raises safety concerns, especially at highway speeds or during emergency maneuvers. There was no prior warning of water intrusion or external damage that would reasonably explain this level of corrosion. This appears to be a premature failure of a critical electrical component. Acura has only offered minimal goodwill assistance, leaving the majority of this extremely costly repair as the responsibility of the owner. I am concerned that this may be a broader issue affecting other vehicles and that it could pose a safety risk if not addressed. I am requesting that this issue be investigated. Thank you.

The contact owns a 2022 Acura MDX. The contact stated that while driving at approximately 2 MPH and depressing the brake pedal, the brakes became stuck or jammed. Later, while driving at approximately 15 MPH, the contact again depressed the brake pedal; however, the brakes failed to respond, remained stuck, and failed to stop the vehicle in an intersection, causing the contact to steer to the right and resulting in a crash with a government dump truck. The driver’s child informed the contact’s husband that the brakes were not working. No warning lights were illuminated at the time of the failure. The contact associated the failure with NHTSA Campaign Number 25V391000 (Service Brakes, Hydraulic). The driver's iPhone detected the crash and automatically contacted the emergency contact and the state police. The driver sustained injuries to the knee, head, neck, and back and was transported to the hospital for medical assistance. There was no airbag deployment, fire, or police report filed; however, a police officer and the state police were present at the scene and moved the vehicle before photos could be taken. The vehicle was towed to an impound lot and later to an auto body shop. The local dealer was contacted and confirmed there were no recalls applicable to the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 65,000.

As I was turning right (slowly accelerating from a complete stop) into a shopping center parking lot, I was entering into the lane behind a vehicle that had just passed in front of me (and was headed in the same direction I was going to turn). My 2022 Acura MDX Low Speed Braking Control system engaged for no reason. The breaks slammed hard bringing the car to a hard, sudden stop, and I thought I had been rear-ended by the car behind me. I pressed the gas slowly again and was able to pull into a parking spot and checked my back bumper…PERFECTLY FINE! I googled the issues I experienced and found this is a common problem! This is a dangerous problem! Please hold Acura accountable to fix this issue! For now, I have to remember to turn this Low Speed Braking Control System OFF EVERY TIME I power on my MDX! I am now scared to drive my car!

When the vehicle decelerates—either from high speed or while already moving slowly—it frequently jerks just before coming to a complete stop. This issue is especially noticeable at very low speeds or during final braking, where the vehicle may lurch forward by a few inches unless the brakes are applied firmly. Despite multiple visits to the dealership, including transmission resets and software updates, the problem persists. The dealer has not provided a resolution or adequate follow-up. This behavior poses a serious safety risk, particularly in high-traffic areas where precise stopping is critical.

I was driving to work yesterday morning- busiest time of day on probably the busiest road in our area. My car started freaking out randomly. It popped up numerous errors. The steering wheel locked up. The brakes weren’t working well. I had a car behind me. THANKFULLY they were paying attention because they were very close to rear ending me. But they dodged me. I finally jerked the wheel and got it pulled over to the side of the road until someone could come get me and take me to work. There could have been a different outcome. After being hit head on in February of this year, this incident was NOT good for my PTSD!!!! My anxiety has been through the roof since this incident with a car that I bought SIX MONTHS AGO! As soon as I can trade this car off and get something else, I will be. We still don’t know what it’s wrong with it. We are going to have it towed somewhere on Monday. This was a major safety risk for me AND for the others on the road!!! If my kids had been in the car, I would’ve been even more upset over the situation.

While driving with my small children in the vehicle, my 2022 Acura MDX suddenly displayed multiple simultaneous system failures without warning and the steering wheel locked and the car slowed and the brakes didn't work well: •Brake System Problem – warning that braking performance may be reduced •Electric Power Steering Problem – “Do Not Drive” warning •Vehicle Stability Assist Problem •Hill Start Assist Problem •All Wheel Drive System Problem - •Adaptive Cruise Control Problem •Collision Mitigation Braking System Problem •Lane Keeping Assist System Problem •Trailer Stability Assist System Problem •Brake hold system problem •Vehicle Stability Assist Problem •Electric Power Steering System Problem •Low Speed Braking Control Problem •Road Departure Mitigation System Problem These failures created a serious risk to my life as well as my children's lives by simultaneously disabling braking, steering assist, stability control, and AWD traction. If this had occurred at highway speeds or in a location without space to maneuver, it could have caused a severe crash and even death. The vehicle was towed to the dealer immediately.The tow truck driver stated that he had transported another 2022 Acura MDX with identical failures earlier the same day, suggesting this may be a widespread defect. The dealer found no recalls and attributed the issue to a steering angle sensor malfunction. Given the severity and the risk of injury or death, I am reporting this to NHTSA. Request: NHTSA investigation into whether this is part of a broader safety defect affecting 2022 Acura MDX models, and whether a recall or manufacturer corrective action is warranted.

On [XXX] I headed out for an event. I had been driving for 8 minutes when I lost the ability to steer, the Brake, TSA, and Steering system warning lights flashed on the dashboard and I immediately turned onto a side street. One message stated to contact dealership immediately, DO NOT DRIVE. The car was towed to Mungenast St Louis Acura. It was scheduled for service on Monday, June 23, already, so this was perfect. It was determined the battery failed. My concern is that prior to this event the vehicle's warning system gave no indication the battery needed attention, was low in power, or anything else related to the battery. I was on a busy street however, this event could have been very much different had I decided to take the highway to my event.

Acura Headquarters USA 1919 Torrence Boulevard Torrence, California 90501 Mr. [XXX] [XXX] [XXX] Email: [XXX] Dear Sir or Madam, I am writing your company to the attention of whomever oversees the product development and design of the 2022 ACURA MDX and to warn them that certain system features and design flaws of this make and model vehicle will undoubtedly lead to the death of someone in the near future as was nearly the case with myself and spouse very recently. On Sunday [XXX], my spouse and I attended church services that morning. Fortunately, after services our Acura MDX did start as usual, and we began our journey home.Upom arriving home, we backed our car into our garage and during that process thankfully I had the wits to unlock the passenger and driver side door mechanisms. Once we enteredthe garage and at thta point, our car went absolutely DEAD. Our car stayed dead for the next 5 1/2 hours. Had I not unlocked those doors, we would have been trapped inside for that duration of time, only to be found dead fron suffocation and asphysxiation from being in a car with all the windows rolled up, no power to the vehicle and no way to get out, while beingdeprived of oxygen. AT that point, your manufactured vehicle became a death trap for us.We're the fortunate ones who lived through the experience and to be able to tell the story. Others may not be so lucky to tell theirs and there will be others. We wanted the manufacturer to understand the full implications of our letter and to stress in the strongest terms possible that this is a very serious matter that will eventually cost lives, as it nearly cost us ours. The vehicle in question is VIN# [XXX] and was last serviced at Vandergriff Acura in Arlington, Texas on 6/13/2025 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle has a battery issue, we replaced the battery twice in two years still the issue might happened again and again. Once the battery start draining energy, everything start blinking and car stops all of a sudden in the middle of the road because of brake assistance problem. All the system errors come up. It is very scary to drive the vehicle with my kids inside. All system in car works with battery. service center told me that this kind of cars needs bigger battery and company only put small batteries in the car. Company don’t put warranty on battery if it is replaced under car warranty. My car is only 33 months old and i have to change battery twice, It might happen again. Please help me to resolve the problem. It looks like factory problem that company do not make sufficient batteries to satisfy the vehicle needs. I have attached the pictures of safety lights.

While driving the vehicle and while it was in motion, I received a wave of faults. The power steering, lane departure, brake system, brake hold system, vehicle stability assist, hill start assist, trailer stability, and adaptive cruise control all failed. Consequently, the steering wheel locked completely while the car was in motion. I couldn’t steer at all, and the car was in motion! I informed American Honda and the dealer, who informed me that “they had never heard of such a problem”, and that they were “unable to duplicate the issue” when the tow truck brought it into the shop.

While driving on a major highway, several warning lights, including the brake warning, appeared on the dashboard. Simultaneously, the vehicle lost power steering, making it extremely difficult to steer and creating a hazardous situation for the driver and others on the road. The driver managed to pull over and turn off the vehicle. Upon restarting, the warning lights were gone, and the steering returned to normal. The car was taken to a local Acura dealership, but they couldn’t find any error codes or replicate the issue. After a week of driving without any problems, the car was brought back to the dealership. This time, a district Acura technician recommended replacing the steering rack. The dealership informed us that Acura would disassemble the old steering rack to investigate the issue further and determine if it was the cause. Acura will decide on a recall if enough vehicles are affected.

I've recently been in touch with an Acura dealership about my vehicle's wireless charger not working. So shortly after purchase I made my complaint that the wireless charger pad is not charging my phone. They've replaced the pad but still not charging my Samsung ultra 22+ unless the car is parked and sitting still. They've asked me to allow time for researching the issue and taken all the make model details from my phone. Well sadly a few other things recently became noticeable to me as well and I will be following up with the dealership to address them as well as I'm not satisfied with my truck and the many issues I'm experiencing. 1) Jerked when coming to a stop to reverse into my driveway 2) A loud Thud noise could be heard inside my truck although I had the radio on when switching from park to drive or drive to park. 3) Car stopped kind of midway when reversing jerking me in the process leaving me wondering why or what was going on. 4) Engine would rev to 7000rpm even though I was going less than 45 mins per hour....just baffling honestly.

On 8/20/23 heading south on I-294 in Chicago : in center lane with cruise control on and no cars close in front of me when the car suddenly started a hard braking without warning. No orange warning to brake came on but engine warning light of left of dashboard was on. Immediately turned off cruise control. Car would not accelerate and came to a stop on the highway. Tried to start without success, then restarted and the car came on but in neutral. It had been placed in Park before shutting off. Car started and drove uneventfully back to Indianapolis. Took to Acura dealer and diagnostics were run showing that "position range" switch or sensor had been activated. Told it was safe to drive. We do not agree and are selling the car. Dealer, or service Dept was very lackadaisical about the incident. I will contact Acura corporate headquarters as well.

All electrical systems failed while driving around 30mph, Power steering failed, power brakes failed, lane assist failed. We were at high risk of a crash due to lack of control of the car while driving. We were lucky that it happened on a flat road and we were able to manually pull over to the side of the road. The vehicle was inspected by the manufacturer and we were told that the car did show all the steering angle sensors did malfunction and fail. They said there is no known cause. They just recalibrated and reset the sensor and said it now is ok "at this time." There is no guarantee that the problem won’t happen again and put my family’s life in danger. Prior to this incident we repeatedly got the "BRAKE SYSTEM: Brake system problem, Brake performance may be reduced, See your dealer". We took it into the deal and was told nothing is wrong with the car and this is a known issue. Dealership Service video: https://app.truvideo.com/v/CbRSGHvo?s=46jtvtJ1AFXkZdwwQ3gE7pDBzV4dlDl0

I was driving my 2022 Acura MDX on interstate highway in the middle lane of a three lane road. We had our panoramic sunroof closed, but the interior sliding sunroof door was fully open exposing the entire panoramic sunroof. After a period of time and without indication or warning, the sunroof exploded (sounded like a gunshot when it exploded) sending glass throughout the interior of the vehicle as we were driving at highway speeds. We were lucky that there were no vehicles next to us when the explosion happened because I swerved out of my lane temporarily not knowing what just happened. We were not anywhere near overpasses, trees, or any other hazard that might have dropped an object onto the top of the sunroof. Additionally, we did not see any road debris flying towards our vehicle. Fortunately we were near home and we slowed the vehicle down to exit the freeway and made it home to further examine the damage.

The vehicle makes noise while shifting from Park to Reverse to Drive. Transmission fluid and oil fluid leaking while I had driven only 450 miles. Had reported the issue to the Service Department. They informed that since the engine is new it will take a while for the transmission gear to quiet it down. They can't find any leakage for the first two times when I brought the vehicle for them to inspect. Their Service Manager was able to identify the issue and assigned the technician to trace it down. My car is currently in their shop for the third time since I just purchased it on August 19th, 2021.

Iam having numerous problems with the start stop function of my 2022 MDX. See attached letter and documentation for full details. I also attached the documentation from my dealership for the repair order history. There have been numerous of times that this problem occurred that I didn't bring it in for service.
