2025 HONDA ODYSSEY Complaints

Auto Idle Stop feature has caused the vehicle to stall / shut down at a stop light on several occasions causing hazard when we can't drive. Entire engine has to be stopped and restarted which is scary in heavy traffic.

After approximately 60 miles of highway driving, I was stopped at a stop light and the auto engine off feature automatically shut the engine off. When I lifted my foot from the brake pedal in attempt to accelerate forward, the van did not turn back on and a battery warning light showed on the dash. I attempted to restart the van without success x 2, it was not turning over. My van was stalled in the middle of the road, cars passed around on both sides. Upon my third attempt to restart the van, it did restart and I have had no further issues since. Though, I have been shutting off the auto engine off feature since that time. I understand there is a well known issue with the auto engine off feature of Honda Odysseys in this generation. I am respectfully advocating for a formal recall as a stalled van in the middle of traffic poses significant risk to the public.

When at a stop, the van is supposed to start again. There have been at least 4 times now that it did not automatically restart. After the 3rd time, I was at the dealer for routine maintenance and mentioned it. He said if it does it again to let them know and they will need a full day to look at it. The most recent time I was at a major intersection in town at a red light. Light turned green and the van would not go. My adult son was with me and said it took about 30 seconds for me to get the van going again. It is scary because I live in a busy town. The service advisor said he has the same van and ALWAYS turns the idle stop to off when he drives. I try to remember to do it, but sometimes I forget. I am calling the dealer now but really don't want time without a vehicle.

-Defective Starter. -Starter randomly fails to restart vehicle after being warmed up. -When the DC motor internal copper windings get heat soaked after being driven and warmed up, the motor's internal resistance gets too high to draw sufficient current to turn over engine properly. This happens when intentionally shutting off motor (ie. getting gas, going into a store then coming out in a few minutes), the engine either will not crank at all, or cranks about two engine revolutions, will not start and then stops trying and remains in full accessory mode. It will not attempt a restart either. The only remedy is to fully shut down the vehicle, then try a fresh start after a few seconds. Sometimes it will start the engine, sometimes it will repeat the issue and you have to try again. This is EXTREMELY DANGEROUS when this problem occurs when the vehicle is at an intersection or traffic light, shuts itself off due to the auto-start/stop, then fails to restart the engine when expected when the light turns green. Especially at traffic lights if you're the first car in line., and especially if you're the first car to go with traffic behind and in a single lane of traffic. Having to totally shut the car down, then do a fresh restart while blocking an intersection with tons of cars behind and all waiting on your car to decide if it wants to re-start with cars flying around you into the shoulder or ditch to get around is an extremely dangerous position to be in, forcing other drivers into doing ridiculous things to get around you and WILL if not already cause major accidents. I believe Honda knows this is an issue. They are blaming bad batteries and alternators which can easily be ruled out with independent battery and alternator testing in the vehicle, while the problem of no/slow cranking remains. The problem IS defective starters, that have or will absolutely cause accidents by stranding vehicles in intersections because of failures to restart.

This was an auto stop-start system failure. The Honda dealership in Frisco inspected and attributed this to battery life but did not guarantee this was the cause of the issue. There were no other signs of failure prior to the incident. A description of the incident is below. While turning right departing a parking lot, the vehicle auto stop-start enabled during the brief stop and the feature turned off the vehicle. When accelerator was pushed to proceed, the car started flashing lights with a warning message on the dashboard, the car was then automatically put into park by the system, and would not proceed to move without turning the vehicle off and back on. If this had occurred in another location, it would have been extremely dangerous as it took some time to turn the vehicle back on.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving off the expressway and stopping at a red light, the contact pressed the ECON button, and the vehicle failed to start. The contact opened the driver’s side door and press the start button to restart the vehicle. The vehicle was restarted and operated normally. The contact stated that the failure had occurred on two separate occasions. The cause of the failures were not yet determined. The local dealer was notified of the failure, and a service appointment was scheduled. The manufacturer was not yet notified of the failures. The failure mileage was 8,000.

Engine fails to restart after the Auto Idle System shuts it down, leaving vehicle stranded in traffic. The issue is sudden and unpredictable, and may not appear in inspection. A stalled car in live traffic is a safety concern. The vehicle is at a dealer for diagnosis and repair. No warning appeared before the problem began happening. (About 5 times in 2.5 months.) Sometimes when it occurs, a brief error message seems to appear on the dash, but quickly disappears. It usually takes cycling through restarting the car to get going again. Not a good environment to stop and take video, although it's almost impossible to record.

While driving straight on the highway on a sunny day the car left the lane on it's own, resisted attempts to get it back into the lane, and crashed into the concrete barrier after we swerved around and the car bounced around. Lane keeping assistance and automatic cruise control were active. The lane lines looked perfectly fine. A couple minutes before the accident the car left the lane unexpectedly but we were able to get back into it. Before going on the trip we took the car to the dealer and complained about issues with the car not starting after it shut off while idle at stop lights, or not starting properly, like engaging the parking brake and getting stuck, or starting and rocketing forward even when I only pressed lightly on the gas, leading to loss of traction. They checked the car and said everything looks fine and the tires have 5mm of tread and don't need to be replaced, and they rotated the tires and changed the engine oil. I'm not sure if the issue was with the power steering failing, or traction being lost, or the sensors having an issue causing the car to think the lane was somewhere else and not letting us leave where it thought the lane was. Driver has tons of bruises still and it's been over a week. The other 4 passengers seem ok. The insurance company said the car is totaled and is taking possession of the car. The only warnings lights or messages the car gave us before the accident were about the car having an issue starting back up when all the cars were beeping behind us when the light turned green, and messages about loss of traction, mainly after the engine started back up.

I am reporting a critical safety issue regarding the auto-start-stop system on my 2025 Honda Odyssey. On June 15, 2026, the vehicle's engine shut off at an intersection as designed but failed to restart, stranding the driver in active traffic and presenting a severe safety hazard. I previously brought the vehicle to an authorized Honda dealership approximately two weeks prior to this incident after noticing early symptoms of this failure. At that time, the dealership diagnosed the issue as low battery voltage and replaced the battery; however, this repair did not resolve the underlying fault. The vehicle continues to unexpectedly stall during traffic stops due to the auto-start-stop failure, representing an ongoing and significant danger to the vehicle occupants and other motorists.

Engine will fail to start when shut off to stop light or when shut off at anytime when engine is hot. Very dangerous situation. Acts like starter is dragging. There is a clunking in the steering column when making a turn mainly to the left that can be felt in the steering wheel. Driver seat is splitting open on the side. Keeps setting code p0441 for evap system..
