When I stop, they start stop, turns the engine off, but when I release the brake, the engine struggles to turn over and sometimes doesn’t and I have to put it in park to restart it. I have taken it to the dealership already once, but they said they weren’t able to reproduce it. I will be taking it back to the dealer to try again.
2025 Honda Odyssey engine complaints
Page 10 of 10: complaints 251 to 263 of 263, newest first, as owners wrote them.
Two concerning and dangerous malfunctions are occurring. 1.)When car is stopped at a light for more than 45 seconds the car engine shuts off, when I press on the gas the dashboard lights up and displays a battery light and advises me to restart the car. The car struggles to turn over. 2.) The car struggles to start on initial start as well. The dealership replaced the battery and it continues to happen, they advised me to disengage idol stop every time I start my vehicle to save the starter and prevent the car from stalling. This is obviously a problem with the Honda idol start that needs to be addressed. There are multiple threads in online forums about this issue with Honda.
Three times now since buying my van about 6 months ago brand new, I come to a stop light, the engine turns off, but then it won't come back on when the light turns green. I have had to put my hazards on while I frantically push the start button multiple times. Eventually it will start up but takes 1-2 minutes. I brought it into the dealer the first time and they blamed it on a weak battery. After it happened 2 more times, they are replacing the starter but I'm afraid that's not going to fix it. While I wait, i just have to turn off the idle start/stop button every time I start my van.
Idlestop fail to restart engine multiple occasions at busy intersections.
The idle engine feature is defective. Often, when stopped and the engine goes idle, it will not restart when the driver releases the brake. The van stalls, and the driver is forced to move the vehicle into park and start the engine again. This is dangerous and stressful because the driver behind you expects you to go, especially when the light turns green, but you are stalled, potentially leading to rear-end accidents.
The contact owns a 2025 Honda Odyssey. The contact stated that the Engine Auto Start-Stop system failed to operate as needed. The contact stated upon coming to a stop, the engine shutoff; however, upon releasing the brake pedal, the contact became aware that the engine failed to restart as designed. A message of a systems failure was displayed, and an image of a pedal and the Push to Start button were displayed. The contact was able to manually restart the vehicle immediately. The contact stated that the failure had been recurring and had worsened. The contact stated that the vehicle could only be manually restarted after 10 minutes, nearly causing a crash. The dealer was contacted, and an appointment was scheduled for a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 16,000.
Brand new vehicle and system shuts down a few times when in idle mode..(stoplight, stop sign) then I need to restart the car again.
At a stop, the fuel save system shut the car off. When you take your foot off the brake the van fails to restart. If you try to restart using the push button the car will still not start because the transmission is still in drive. Then it takes awhile to get the transmission into park/neutral and then the van will start. The problem is intermittent 3 times in the last 2 months. No accidents just blocking traffic. My wife doesn't like that.
After going into Auto-idle at a traffic light. The engine did not turn back on when accelerator was pressed. Even after a restart. It took about 30 seconds.
I think there is a problem with the Auto Idle Stop system that has resulted in the starter needing to be replaced. But, the dealership says nothing is wrong. The Auto Idle Stop malfunction lights up when I let off the brake. I have gotten in the habit of turning off the AIS every time I started the car. However, it still is hesitating to start, which leads me to believe the AIS has killed the starter.
Van completely shut down while in an intersection and the battery light came on. It was hard to restart. Took it to the dealership and they cannot find the problem.
The auto on/off while idling will randomly fail. The car stalls, all emergency lights turn on and the car won’t start for a few minutes. This has occurred at stop lights and in traffic after coming to a complete stop and the car turns off when idling. The car is only 6 months old. The first occurrence happened at the 3 month mark and has become more persistent. I’ve had my battery checked and that was not an issue.
While driving in a construction zone, the vehicle's lane departure system jerked the wheel and almost made me leave the lane Very dangerous. Same vehicle, the A'C was found not operating and a dealer diagnosis found that the system was overfilled and that an electrical connection was not hooked up from the factory. Same vehicle, body panels are not properly aligned from the sliding door to the passenger side door, gap is almost 1/2 inch.
