2025 HONDA ODYSSEY Complaints

The Auto Idle Stop has failed to restart the car when stopped at a traffic light. This has happened twice now, and has caused me to become a road hazard as I am not able to get the car turned back on before the light turns green. This has happened twice in the past month (May 7 2026 and June 1 2026). Have not yet taken the car back to the dealer. No warning lights or anything came on prior to the incident. Just stopped at a light and the engine stopped, then did not turn back on when the brake pedal was lifted.

Noise coming from front driver side suspension or steering column/components. The noise is very light, but sounds like a clunking/rattle and can be felt through the steering wheel. It is intermittent. Because I am unsure what is actually causing the noise, I cannot state whether it is actually part of the suspension system or steering column area. The dealership cannot replicate the noise, so it has been turned away twice now. Does not feel safe. Searching other odyssey forums, it is something that is reproduced by others who have bought a 2025-2026 Honda odyssey.

Car completely turns off when I’m stopped and idle stop has engaged. Seems to happen when the AC is running hard. Sometimes, the car turns back on by itself in seconds. Other times, I have to turn the car back on myself by pressing the “engine on” button, and I struggle to get the car to turn back on. Very dangerous to be obstructing traffic at busy intersections or on a busy highway when stopped while another car ahead is making a turn. I’m scared to drive this car with my children in it. It is a minivan! I understand this is a known issue under investigation by NHTSA, but I’m struggling to get my local Honda dealer to acknowledge and address it. This issue happens at least 1x a day when I’m running the AC.

While stopped at a red light the engine turned off with the engine restart function. When I released the brake the engine attempted to start and then completely stalled. I had to get the vehicle in park and restart the engine with took it a few attempts of pressing the start button. The has happened a few times with this vehicle. Dealers have been unable to replicate the issue to try to solve the problem.

The Honda Auto Idle Stop Start isn't working properly. I applied brake and car turned off, when I released the brake the vehicle did not start. Also vehicle seems hesitant to start at times.

Engine fails to restart on its own from a complete stop at a traffic light or road intersection when the Auto Idle Stop function is engaged

The Auto Idle Stop (AIS) system malfunctions during normal driving. When coming to a stop, the AIS shuts off the engine as designed, but the vehicle then fails to restart when the brake is released. The vehicle shifts itself into Park automatically without driver input, either before or at the same time as a dashboard message appears instructing the driver to depress the brake pedal and press the start button. When the start button is pressed, the dash resets but the engine does not start. The only way to recover is to fully power the vehicle off and restart it, which is difficult and unsafe at a busy intersection or red light. This puts the driver and others at serious risk. The vehicle becomes immobilized in traffic with no ability to move it out of the path of oncoming or following vehicles, creating a risk of being rear-ended. The unexpected automatic shift into Park is also a vehicle control concern, as the driver does not initiate it. The problem is intermittent. The vehicle has been taken to an authorized dealer twice. On the first visit the dealer kept the vehicle several days with a loaner and attempted to replicate the issue but could not. On the second visit the dealer kept the vehicle one day and again could not reproduce it. A third diagnostic visit is scheduled, during which the service manager intends to drive the vehicle to attempt replication. As of now the failure has not been confirmed or reproduced by the dealer. The vehicle is available for inspection upon request. No warning lamps appear prior to the failure. The only symptom is the automatic shift into Park and the dashboard message to depress the brake and restart, which appear at the moment of the malfunction. The first occurrence was at approximately 25,000 miles. The vehicle has not been inspected by the manufacturer, police, or insurance representatives.

The starter is failing and with automatic dial shut off it caused an issue while in middle of intersection waiting to turn. The car would not start and had issues.

The idle stop on my 2025 Odyssey sometimes does not turn back on when it turns off at a red light. I have to then completely turn off my vehicle and turn it back on in order for the vehicle to work again. Also, when first turning on my car sometimes It’s very laggy in fully starting. This is a great safety concern, especially when at a red light or at a stop sign when trying to apply gas and it doesn’t turn back on. This is a problem we’ve heard is being experienced by 2025 Odysseys. The dealership we took it to could not replicate the problem they said the battery was totally fine.

AIS system causes the 2025 Honda Odyssey Elite to stop and fail to restart when stopped at traffic light intersections—the car will not restart which is very scary in traffic with kids in the car. I had starter replaced at a Honda dealership, but the dealer could not say whether it was same part or upgraded part, which means the starter may overheat and shut down again because Auto Idle Stop. This began happening when car was less than one year old.
