At a stop light the van turned off and would not turn back on...finally was able to get it to auto zone who said it was a bad battery, we then took it to honda with it only having 7k miles on it. They determined it was the starter from the auto/start/stop feature. What if this was the highway? A 2026 vehicle this should not happen to.
My AIS system kicked in causing the engine to shut off. Unfortunately, the engine did not restart. I was unable to start my car or even shift it to neutral for a helpful bystander to help me push my car off of the road. I was blocking traffic on a busy road and I am very fortunate that I was not rear ended. Eventually, after about half an hour, was able to get the car restarted (even then, lots of “clicking” and hesitation with starting). I then drove the vehicle home. I took it to Honda and they made me aware today that they were unable to get the car to repeat this problem, nothing was wrong, I could pick it up and let them know if it happened again.
Sitting at a light, the auto stop system activated and shut the engine off. When the light turned green, I took my foot off the brake and the engine failed to. Start and the entire electrical system shut off. The card was completely dead. I sat there for several minutes and I was able to restart the car.
While driving my 2026 Honda Odyssey, I stopped at a red light and the engine shut off through the Auto Idle Stop system. I pressed the Auto Idle Stop OFF button because I wanted the engine running again before proceeding. Instead of restarting the engine, the vehicle completely shut down and became inoperable in traffic. I repeatedly attempted to restart the vehicle, but it remained unresponsive for approximately 20 seconds before it finally restarted. This created a serious safety hazard because I was unable to move the vehicle while positioned in active traffic. This was not normal Auto Idle Stop operation, as the engine should have restarted when I pressed the button. This has happened several times already, where the car will not restart the engine. Requesting that NHTSA investigate possible Auto-Idle Stop/failure-to-restart problems affecting the 2026 Honda Odyssey.
While my 2026 Honda Odyssey was parked and stationary, I operated the driver-side power sliding door normally. The door began opening but became stuck. When I activated the power sliding door again, there was a sudden mechanical failure involving the sliding-door mechanism. The sliding-door rail was severely damaged/deformed, the mechanism appeared to disengage from its normal track/rail path, and the fixed rear quarter/third-row side window shattered. Exterior molding covering the rail was also dislodged and fell to the ground. There was no collision, accident, external impact, obstruction, or other outside force involved. The failure occurred during normal intended use of the power sliding door. Fortunately, my three children had already exited the vehicle. The shattered glass is directly adjacent to a passenger seating position normally occupied by my children, creating a serious risk of injury had a passenger been seated there. There were no warning lights, messages, or known prior symptoms before the door became stuck. The vehicle has not yet been inspected by Honda or a dealer. It is currently parked at my residence and is available for inspection. I have extensive photographs taken immediately after the incident documenting the damaged rail, shattered glass, displaced molding, and debris. After the incident, because I was approximately three hours from home with my three children, I was able to carefully reposition the door enough to close and secure it, temporarily cover the shattered window, and drive home. The affected sliding door has remained closed and locked since, and I am no longer operating the vehicle pending inspection.
Idle stop function error during waiting at red light. Engine failed to restart so i had to turned it off and restarted the engine at the traffic light. Happened twice already. Idle stop system is defective need to be recalled
I own a 2026 Honda Odyssey Elite equipped with the factory rear entertainment system and Apple CarPlay. When using Apple CarPlay navigation (Apple Maps, Google Maps, or Waze) while passengers are watching a movie on the factory rear entertainment system, every navigation voice prompt causes the movie playback to stop. After playback stops, the movie cannot be restarted from the vehicle controls. The only way to restore normal operation is to stop the vehicle, turn the vehicle completely off, restart it, reconnect Apple CarPlay, and restart the movie. However, the problem repeats the next time a navigation instruction is given. This creates a driver distraction because passengers immediately ask for the movie to be restarted, and the driver is presented with an infotainment system that does not respond as expected while the vehicle is moving. Drivers may attempt to troubleshoot or repeatedly interact with the infotainment controls instead of focusing on driving. My Honda dealership advised me they were able to reproduce this issue on multiple new 2026 Honda Odyssey vehicles on their lot, indicating that this is not unique to my vehicle. Honda Customer Relations has also been notified.
I own a 2026 Honda Odyssey Elite. On multiple occasions, the Auto Idle Stop system shut the engine off while stopped at a traffic light. When I released the brake pedal to proceed, the engine failed to restart, leaving the vehicle disabled in traffic. I was forced to shift the vehicle into Park and manually restart the engine using the Start/Stop button. This defect has occurred multiple times. I first reported the issue to my Honda dealership on June 2, 2026. After two visits where the dealer was unable to duplicate the concern, I captured the failure on video. During my third repair visit, the dealership's engineer personally experienced the failure twice while testing the vehicle. Honda Customer Relations opened a case and worked with the dealership. The dealership ultimately replaced the battery but advised me that this was only the next diagnostic step and not a confirmed root cause of the failure. This defect creates a significant safety hazard because the vehicle can become immobilized in an active traffic lane after the light turns green, exposing occupants to the risk of being struck by other vehicles.
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.
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.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
