2026 Honda Odyssey: Recalls, Complaints & California Lemon Law

Moonroof exploded while driving 55 mph. I took pictures. It was completely distracting while driving and a very scary incident. Searching online provided a class action lawsuit against Honda for this issue. We have not been able to get it looked at due to it being the weekend and the service department is not open. No police were called. Insurance claim started. No warning before it happened.

I was driving down a 35mph road, the car in front of me slowed down, I was about 2 car lengths behind it. No notice, no warning, my Odyssey SLAMMED on the brakes and brought me to an abrupt stop with no notice and no need. Everything in the van flew forward and in the floor. Luckily there was no one directly behind me. It gives me serious whiplash when this happens and it is uncalled for, the car in front of me did not stop it only slowed down, there was plenty of room between our vehicles (we were only going about 30 mph) and there was absolutely no warning- just BAM! and my van was stopped in the middle of the road. Something needs to be done about this, someone is going to be killed! I took it to the dealer the last time and they said the van did not record it. So another easy out for Honda! And nothing they can do...

On November 12, I was on the highway in the right lane, there was a car about 4 car lengths ahead of me in my lane and the car in the middle lane was quite a distance ahead. Just as I got in the middle lane, BOOM! the vehicle's CMBS malfunctioned and slammed on the brakes - no warning, visual or audible, just came to an abrupt stop. Thank goodness no one was behind me or I would have been dead. It was an instant whiplash effect as well And then as I was then merging back into the right lane to exit the highway, it did it again! There were NO cars anywhere near me as I had slowed down due to the trauma from the first braking malfunction and all the cars were quite a distance ahead and thank goodness there were no cars behind me. Then on November 25, the same thing happened again. Driving down the highway, no cars near and BOOM! I am brought to an abrupt stop in the middle of the highway! The CMBS malfunctioned again in the middle of the highway. I took it to the dealer and conveniently there were no codes so they said there was nothing they could do. Someone needs to do something about this! To answer your questions 1) CMBS system is malfunctioning and has been for quite some time on Honda vehicles 2) If there would have been a vehicle behind me, I most likely would have been killed. If my dogs would have been in the van, they would have been injured. It gave me whiplash 3) I took it in and they did nothing until I complained, then they kept it a second day and drove it and said it didn't do it. But they weren't even going to do anything until I pushed the issue. This is a known issue with Honda as I found out AFTER it happened to me. 4) the dealer 5) Absolutely NO warnings before it happened

The Auto Idle/stop caused my engine to stall not once but twice in the past few weeks while on a major highway. Light turns green and my car won't start back up. I have to let the car sit for a second then restart the car while traffic is flying past me on this highway. Absolutely ridiculous that my brand new car is having these issues and that I am unable to turn this feature off permanently.

My 2026 Honda Odyssey was stopped at a traffic light with Auto Idle Stop engaged. When traffic was ready to move, the engine appeared to restart for about half a second and then shut down. The vehicle then shifted itself into Park and would not resume normal operation. The battery warning light was illuminated. Pressing the engine Start/Stop button caused all of the screens/displays to turn off briefly, but they came back on in the same failed state. The vehicle was disabled in traffic at an intersection. The component or system that failed appears to be the Auto Idle Stop / engine restart system, possibly involving the starter, starter relay, battery/charging system, or engine control software. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because the vehicle unexpectedly failed to restart and became disabled while stopped at a traffic light, creating a traffic obstruction and risk of being struck from behind or causing other drivers to maneuver around the vehicle. The problem has not yet been reproduced or confirmed by a dealer or independent service center. UNKNOWN whether diagnostic trouble codes were stored. The vehicle/component has not yet been inspected by the manufacturer, police, insurance representatives, or others. There were no warning lamps, messages, or symptoms prior to the failure that I noticed. The battery warning light appeared after the engine shut down and the vehicle would not restart normally.

This is a report on a design flaw- not a failed component- in the 2026 Honda Odyssey's "smart" computer automated safety features, including automatic braking, lane departure, and forward collision warning systems. There have been two types of incidents. These incidents have been repeated on this vehicle dozens of times in our first year of ownership. These incidents are potentially very dangerous because they involve erroneous automatic braking at interstate highway speeds. Unexpected erroneous braking at interstate speeds is a good way to cause a rear-end collision or loss of control. 1. Automatic emergency braking due to erroneous lane departure detection. On interstates in Arizona at highway speeds of 65 MPH, the vehicle's lane departure detection system throws erroneous warnings when it sees non-lane markings on the roadway, such as tar sealant strips or seams between pavement sections. This has resulted more than once in the vehicle erroneously applying emergency automated braking to slow the vehicle. This happens even when lane assist and adaptive cruise control are turned off by the driver. 2. Erroneous automated braking while overtaking another vehicle. On interstates in Arizona at highway speeds of 65 MPH, while passing in the left lane a vehicle that is moving much slower in the right lane (e.g. semi truck climbing a hill at 40 MPH), while using adaptive cruise control, automated braking is applied erroneously when there is no risk of a forward collision. The automated braking tends to kick in far earlier than a human driver would brake, and when there is no vehicle in the lane ahead, so it is unexpected and dangerous. This only happens while adaptive cruise control is activated by the driver.

While changing lanes to an off-ramp the Collision Mitigation Braking system suddenly activated along with a collision warning beep even though there were no automobiles nearby to trigger the warning. No cars in front of me and no cars to the right of me in the exit lane. My car immediately braked and tried to steer back into the main roadway, away from the exit lane. The lane departure light did also come on due to me not using a turn signal prior to the lane change, but there was nothing else around to trigger a proximity alert nor to respond to.

The vehicle’s Blind Spot Warning system intermittently fails during normal operation. The warning message “Blind spot information system problem. See your dealer.” appears after driving or after restarting the vehicle. The system may function initially (for example, when leaving a garage), but then disables itself during driving or after the vehicle is parked and restarted. The issue first occurred within the first week of ownership and has persisted and become more frequent over time. The vehicle currently has approximately 4,500 miles. This failure affects a driver assistance safety feature intended to warn of vehicles in adjacent lanes that may not be visible to the driver. The malfunction creates a safety risk because the system becomes unavailable unpredictably during normal driving conditions. The failure is intermittent and cannot be consistently reproduced at a service appointment. The vehicle has been presented for service; however, the condition could not be diagnosed because the warning was not active at the time of inspection. The dealer advised that the issue could not be evaluated without the warning present. Proposed options included leaving the vehicle for an extended period to attempt to reproduce the intermittent condition, or returning when the warning is active. Due to the unpredictable and intermittent nature of the failure, this approach has not resulted in a diagnosis or repair. The failure remains unresolved. The system failure occurs during routine commuting and affects the ability to safely monitor adjacent lanes when changing lanes.

The contact owns a 2026 Honda Odyssey. The contact stated that while driving on several occasions at various speeds, the blind spot monitor became inoperable with the message "Blind Spot Information Systems Failure - See Dealer" displayed. The contact also stated that while in the driver assist mode, the message "System Could not be Retrieved - Please try Again" was displayed. The vehicle was taken to a dealer where it was determined that a systems update was needed but was not currently available. The vehicle was not repaired. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was 6.

Observed repeatedly while operating at highway/interstate cruising speed, with adaptive cruise engaged: any changes in road texture - concrete to blacktop, between different types of blacktop or concrete, separation joints, etc - such as when crossing a bridge, crossing state lines, entering open-road toll plazas, etc - results in a sharp lifting of the throttle and at times will also automatically engage the brakes. This results in rapidly and unexpectedly cutting speed by 10-15 mph before automatically resuming set speed 1-2 seconds later. This has resulted in trailing vehicles to think I am brake-checking them or otherwise caused them to abruptly brake or swerve out from behind me. It also can cause driver and occupants in the Odyssey to lurch forward and back unexpectedly - which has had a residual affect of unintended input on the steering wheel, cascading into unintended direction change and amplifying vehicle instability issues already introduced by the sudden speed change. There are multiple other owners of 2018+ Odysseys on the forum [XXX] which have reported similar situations. I have tried to encourage them to register their observations here. I believe this issue poses a significant risk to the operator and occupants, as well as surrounding motorists. Rental/fleet vehicles with drivers who are otherwise unfamiliar with the issue would be at exceptional risk. I have experienced this issue numerous times as I live near & frequent highways and interstates with these types of road conditions nearby.
