2025 HONDA ODYSSEY Complaints

My brand new vehicle continues to leave me stranded at stop lights because of the auto start stop system. Even though I have already taken it up to the dealership before and had it repaired. (There is a class action started over this)

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

I have experienced numerous instances where my car will stall at a stop light and then fail to restart, even with switching gears to park before resuming to drive.. I have had to turn on and off the engine multiple times at a si hole stoplight before the car would resume movement. This scenario has now happened at least 3 times. I am a mom driving a minivan of kids and this is concerning for our safety. These are not long stop lights. Sometimes even at a stop light I feel a strange pulling sensation.

Right side middle row seat belt does not detect when the seat belt is connected and beeps constantly on and off. Started happening right after the manufacturers warranty ended (36k miles).

The van is experiencing the auto stop-start defect causing major safety issues for my family. The car stalls randomly at stop signs and stoplights and is unable to be restarted quickly, creating a major traffic and safety hazard. The car often will not turn on at start up. The dealer stated that it needed a new starter. Then said that Honda would not replace the starter until a tech looked at it. Then after several weeks still had not moved forward getting a tech. Then said to bring the van in for them to keep until they could get a tech, and offered a small car without room for the kids as a loaner for the indefinite amount of time they want to keep the van. There were no warning lights when it has happened. This issue is already being investigate by the NHTSA - Investigation Number EA25004. This is a known issue for Honda and I am unable to get a safe vehicle or get my vehicle fixed. Below, i have to choose a date for the incident, but this is ongoing and has happened on more dates that I can possibly log. It happens weekly, if not daily.

The contact owns a 2025 Honda Odyssey. The contact stated that the engine auto start-stop system failed to restart the vehicle while at a complete stop, requiring the driver to manually restart the vehicle after several attempts. The message "Shift to Park to Start Vehicle" was displayed. The vehicle was taken to the dealer, where it was diagnosed with a loose battery cable and the battery was replaced; however, the failure recurred. The vehicle was not further repaired. The manufacturer was notified of the failure and informed the contact that a case manager would follow up. The failure mileage was approximately 5,000.

Several times, The Odyssey won’t restart after the Auto Idle Stop kicks in at a stoplight.

The AIS system does not start back up at a light. Sometimes throws itself into park. Last week it started up, but everything shut down about 75 after the traffic light. The entire car loss all power. In the middle of traffic. Needed a policeman to wave cars around e in the middle of the street. Took to the dealership; they kept it for two days and could not recreate the situation. The car had the same problem with start up two days later after leaving the dealership

Starting problem. The vehicle sometimes (randomly) refuses to start after shutting off. For example, after filling gas, or turning off (idle off) at a stop light. It just refuses to start. Terrifying. Researched on the Internet and found thousands of complaints about this going back years. This needs a recall.

The engine fails to restart on its own from a complete stop at traffic light, following the release the brake pedal (Auto Start - Stop). The vehicle will turn off in Drive while idling at the traffic intersection stopped for traffic light. This is a safety concern, that the safety sensor allowing for the vehicle to turn off while vehicle is in drive, could this also happen while driving.
