NHTSA Complaint #11694929 — 2025 HONDA ODYSSEY

The idle stop system is malfunctioning. I had it inspected once previously and now trying to get it inspected again for the same occurring issue. The dealership continues to tell me to turn off the idle stop feature on the vehicle. My safety was put at risk because of the vehicle stalling and not kicking back on while being stopped at a redlight on a busy 4 lane highway multiple times now. The first time, I was by myself. The second time, my 8-month-old was in the vehicle with me. This causes a lot of panic as there are impatient drivers around me since I am unable to move my vehicle. I fear that this could happen on a freeway if there was construction, an accident or even while trying to turn in an intersection and getting hit because I can’t move my vehicle and often have my two small children with me. The first time the idle stop stalled, it occurred twice in a week. The first time was rather quick, and the engine kicked over quickly so I did not think anything more of it. The second time which happened a few days later (9/17/25), took about 5 minutes to get the engine going again and moving on the road (4 lane highway). I took it back to my local Honda dealership where they performed a diagnostic test and discovered the battery had dipped down to 7.22V when trying to restart, the battery failed the battery test and ended up being replaced with a new battery. The idle stop issue has now happened for a third time (10/21/25), with the same issues occurring and I am waiting to be able to get back into Honda. The vehicle has only been looked at by my local Honda dealership. There were no warning lamps, messages, or other notifications prior to the failure. I received a warning on the dashboard after the events occurred on how to start the vehicle. This is very disappointing as a new Honda owner. My husband and I decided on Honda over other car companies due to their reliability and this has now become a constant worry.
