Auto Idle Stop feature has caused the vehicle to stall / shut down at a stop light on several occasions causing hazard when we can't drive. Entire engine has to be stopped and restarted which is scary in heavy traffic.

I am reporting a critical safety issue regarding the auto-start-stop system on my 2025 Honda Odyssey. On June 15, 2026, the vehicle's engine shut off at an intersection as designed but failed to restart, stranding the driver in active traffic and presenting a severe safety hazard. I previously brought the vehicle to an authorized Honda dealership approximately two weeks prior to this incident after noticing early symptoms of this failure. At that time, the dealership diagnosed the issue as low battery voltage and replaced the battery; however, this repair did not resolve the underlying fault. The vehicle continues to unexpectedly stall during traffic stops due to the auto-start-stop failure, representing an ongoing and significant danger to the vehicle occupants and other motorists.

Vehicle shuts off with with the start/stop feature. then will not restart the motor after taking foot off the brake causing a dead vehicle in the road with no warning. Then its a scramble to get it to restart and its difficult to start. this happens at random and seems like honda refuses to fix.

Engine will fail to start when shut off to stop light or when shut off at anytime when engine is hot. Very dangerous situation. Acts like starter is dragging. There is a clunking in the steering column when making a turn mainly to the left that can be felt in the steering wheel. Driver seat is splitting open on the side. Keeps setting code p0441 for evap system..

When at a stop, the van is supposed to start again. There have been at least 4 times now that it did not automatically restart. After the 3rd time, I was at the dealer for routine maintenance and mentioned it. He said if it does it again to let them know and they will need a full day to look at it. The most recent time I was at a major intersection in town at a red light. Light turned green and the van would not go. My adult son was with me and said it took about 30 seconds for me to get the van going again. It is scary because I live in a busy town. The service advisor said he has the same van and ALWAYS turns the idle stop to off when he drives. I try to remember to do it, but sometimes I forget. I am calling the dealer now but really don't want time without a vehicle.
