2025 Honda Odyssey Electrical system Problems

“Auto Idle start stop system failed to start vehicle while. We were stopped at a red light auto idle shut down the engine once the light turn green and we attempted to move forward the auto start failed to cycle resulting in a stalled vehicle on the road, potentially increasing risk to passengers and other drivers on the road. This has happened multiple times.”

“The Auto idle stop feature fails to restart the car during a stop. This happens intermittently but requires one to fully put the car in park and restart the car. This issue has caused concerns as I was at a stop light with a long line and did not know how to recover until I tried to full shutdown, set the car to park, and restart.”

“When starting the car it takes a long time to officially start. This could leave me stranded. A Honda dealer has confirmed this is an ongoing issue as well as other car shops. It started to appear a few weeks ago. I have video I can send. The auto start stop system has shut the vehicle off in the middle of an intersection which could cause an accident or me being stranded.”

“I am having issues with my auto start/stop, also, occasionally has issues starting from a cold start! I was at a red traffic light, and once the light turned green I went to go and my car died. I had to put it in park and try and restart it and it took me three times for it to restart. Everybody was honking at me. This is a safety issue.”

“While driving my 2025 Honda Odyssey, the Auto Idle Stop system shut off the engine at a stop as designed, but the engine failed to restart when I released the brake pedal. This left the vehicle stalled at an intersection. No warning lights appeared. This has occurred 6 times. Dealer was contacted; service is scheduled”
