2024 Honda Odyssey Engine Problems

Your Honda Odyssey's Auto Idle Stop feature has failed to restart the engine twice, leaving you stranded at traffic lights in heavy traffic — once while driving alone and once with a child in the car. Both times you had to exit the vehicle in the middle of the road during rush hour, creating a dangerous situation. Your battery tested good, and the dealer hasn't been able to reproduce or confirm the problem. The fix will likely involve diagnosing the Auto Idle Stop system and its restart mechanism, which may require dealer service or software updates.

Vehicle is idling rough. Took to dealership and they said it has an obvious misfire. Over a total of six days they had it and performed diagnostics that were requested by Hondas Tech line. The dealership told me that they were informed by Hondas tech line that is just how that vechile is. I got referred to Hondas corporate and spoke with them. I was then requested to bring the vehicle back to the dealership for further testing. They had it less than 3 hours. And again I was told that the vehicle misfiring is just a characteristic of the vehicle. I’m concerned about my vehicle misfiring and Honda not wanting to fix it. I don’t want to be driving down the road with my family and have an engine failure. Issue has been ongoing for a few weeks

Vehicle will fail to restart after Auto Idle Stop engages at times. Dealership performed reset, but issue continued afterwards . Safety Issue due to delayed acceleration. Has been brought in twice for this issue with no resolution.

I was stopped at a red light for a long time. The idle on/off feature engaged, turning the engine off as expected. However, the engine would not turn back on; the vehicle completely stalled. It took several attempts to get the vehicle to turn back on. I was on a very busy 5-lane road with my child in the car. This was very dangerous as we were in a middle lane. We would not be able to safely exit the vehicle. I was extremely worried we would be rear-ended.
