2026 Honda Odyssey

I was stopped at the light on Maple and Naper in Naperville. My car engine had turned off as part of the auto idle feature. When I took my foot off the brake, my car did not restart. A message came up telling me to put the car in park. It had already automatically shifted to park and I had to turn the car off and back on to get it to work again. This is a busy intersection and people behind me were honking.

At stop lights, the car engine will shut off. It is supposed to turn back on as you lift your foot from the break to accelerate. Three times now, most recently around 4pm yesterday, the car has not restarted. It shifts to park and an error message comes up on the dash. I’m not exactly sure what the message says but it’s something like car failed to restart, shift to park. I have had to power off my car and power it back on all 3 times to get it to work properly again.

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.

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.

The blind-spot monitoring system on our 2026 Honda Odyssey Elite fails to operate properly in hot weather. When ambient temperatures are high, the system does not detect or alert to vehicles in the adjacent blind-spot areas, and an error message appears stating “blind spot detection unavailable.” This failure increases the risk of collisions during lane changes or merges because the driver does not receive the expected visual or audible warnings of vehicles in the blind spots, potentially endangering the occupants of this vehicle and other road users.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

While stopped at a red light, the Auto Stop/Start system shut off the engine as designed but then failed to restart it. The vehicle remained stalled in the intersection for several minutes while I attempted to restart the engine manually. This left the vehicle and my family stopped in traffic, creating a potential safety risk from surrounding vehicles. There were no warning lamps or messages prior to this incident or after.
