2025 HONDA ODYSSEY Complaints

While idling, the engine shuts off completely and requires the vehicle to be shifted into park and restarted before operation can continue. On multiple occasions, the engine has struggled to restart and cranked for several seconds before turning over. Honda of Tomball in Tomball, TX currently has it. This defect creates a significant safety hazard because the vehicle loses power unexpectedly while in traffic. The vehicle is immobilized until it can be shifted into Park and restarted, leaving us vulnerable to collisions or other accidents, particularly in busy intersections or congested roadways, and creates a serious safety risk to our family, children, and our daughter’s service dog. The vehicle has been presented to HOT multiple times for diagnosis and repair. This defect continues to happen. HOT has inspected this during multiple repair visits. To our knowledge, the manufacturer has not directly inspected the vehicle. (I have requested it with both Honda of Tomball and Honda of America.) No warning lamps or dashboard messages appeared prior to the stalling events. The failure occurs without warning while the vehicle is stopped in Drive. The primary symptom is sudden engine shutdown, followed by difficulty restarting in some instances. This issue began shortly after delivery of the vehicle and has continued intermittently. First documented time of problem was September 2025. Most recent is May 2026.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving approximately 20 MPH, the vehicle inadvertently shut off in the middle of the road. There was no warning light illuminated. The vehicle was immediately restarted and driven to the residence. Additionally, while at a complete stop at a red traffic light, the engine Auto START/STOP system failed to restart the vehicle after releasing the brake pedal. The contact pressed the Push to Start button to manually restart the vehicle. The contact stated that the failure had occurred on several occasions. The manufacturer and the local dealer were notified of the failure. The cause of the failure was not yet determined. The failure mileage was 18,266.

The engine shuts off completely when at a stop after releasing the break pedal. This occurs when the idle auto start is on forcing me to restart the car multiple times with the engine button until it turns on and I am able to continue driving. This is a SAFETY hazard because it happens during traffic and an accident can occur. I have taken it multiple times to the dealer with no replication being able to be done.

The vehicle's auto idle stop system is malfunctioning, resulting in the engine failing to restart from a complete stop. This total failure has occurred on five separate occasions, including while stopped in active traffic intersections. Prior to these total restart failures, the vehicle showed the following symptoms: 1) Initially, the vehicle experienced rough engine idling, abnormal vibrations, and a raw gasoline odor after driving. 2) This progressed to a noticeable delay between releasing the brake pedal and the engine attempting to ignite, during which the starter sometimes sounded strained. 3) This has culminated in the current defect where the engine shuts off normally when stopped at an intersection, but completely fails to immediately restart when the brake is released. This defect completely immobilizes the vehicle in active traffic lanes, exposing us to an immediate and severe risk of a rear-end collision. When the engine fails to restart, the vehicle locks the transmission out of drive and triggers a warning on the dashboard. It is a highly hazardous situation, especially with a lot of distracted drivers on the roadways.

The auto-idle off feature - yes The stall happened in a situation where cars behind me would have expected me to start moving and could have resulted in a rear-end collision. The vehicle has stalled like this three times. The other two times were not in public or traffic situations. It has not been reproduced or confirmed by a dealer or service center. It has not been inspected by anyone else. There were no warning lamps or messages prior to the failure, only after.

I've had several incidents of my car stalling occur since the purchase of the vehicle over the span of 16 months, probably around a dozen times or so. I will stop at a stop light and the vehicle's idle-stop system does not function properly. The vehicle shuts off but does not auto-restart. When I try to manually restart, nothing happens. There have been times where it took several times before the vehicle started back up. Even more seriously, I've stopped in the middle of traffic and the same thing happened. We have had a couple of very scary incidents of cars having to move over a lane to pass our idle vehicle. Thankfully no car hit us due to our idled vehicle. We have owned this vehicle for less than 1.5 years and have had two battery replacements. I've also had the vehicle not start from my garage or parking lot. When I try to start the vehicle a second time, there are times where the start button feels very firm and doesn't push down easily. I have to push the start button several times before the vehicle starts. I'm grateful there have not been any major accidents occur but this is an extremely unsafe situation for the driver and their passengers.

Starter failed to resume engine operation when auto start/stop disengaged motor at a stop light. This resulted in the vehicle being briefly inoperable after the light turned green, requiring other motorists to go around and leaving the vehicle stalled until engine functionality was resumed. Issue was reproduced by dealership, starter motor was deemed defective and was replaced under warranty. Vehicle had rough starts when resuming from auto stop for at least a week leading up to this incident.

Issue with the idle auto star stop. I was driving on the freeway traffic stoped and I press fully down on the brakes and the turned of in stop and go traffic. Took about 5 minutes press and depress the brake pedal for the system to active again.

Many, many times vehicle stop/start feature has failed to start car. Have been stranded at busy intersection having to put car in park and restart car. Extremely dangerous. Took car to dealer and they deny there are any problems.
