2024 Honda Odyssey Engine Problems

The Auto Idle Stop (AIS) feature on our 2024 Honda Odyssey EX-L has recently failed to restart engine leaving driver and passengers stranded in heavy traffic at intersection traffic lights. This has occurred twice, once while traveling alone, once while traveling with five year old child. Safety put at risk because driver had to exit car in middle of road during rush hour traffic while cars attempted to go around. The problem has not been reproduced or confirmed by dealer. Had battery tested at auto parts store and results indicate battery in good condition. Vehicle has not been inspected by the manufacturer, police, insurance representatives. There were not any warning lamps, messages or other symptoms of the problem prior to the failure.

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

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.

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.
