2025 HONDA ODYSSEY Complaints

Auto idle stop feature causes vehicle to shut off completely at red lights and stop signs. This is very dangerous as cars can be coming up behind us in stop and go traffic. Has happened multiple times since we purchased new vehicle in Feb 2025. Vehicle has been serviced by Honda dealership but problem persists.

Engine Idle Stop shuts off engine at stops but completely fails to restart when the brake is released. The vehicle stalls in traffic and requires a manual restart. This has happened four times from a stop, and once while driving on the highway.

Power loss when idle; it fails to restart normally, and then the car stalls for several minutes. It happens frequently despite the van being less than 2 years old (at least 3x weekly)

On multiple occasions, after the engine auto start/stop has turned the engine off at a stop, the engine fails to restart. This leaves the car stalled in the roadway. This has led to multiple unsafe situations as traffic flow is disrupted must divert around the stalled car in the middle of the roadway. There have been no other warning signs or symptoms leading up to this issue. The vehicle has not yet been inspected, a inspection at a Honda service center is scheduled for next week

Once the vehicle's auto idle stop system engaged at a traffic light, and the engine failed to restart automatically leaving us stranded in active traffic. We usually disable the system but forgot that time. It has also required multiple manual push-button attempts to start from a parked position at home and in public parking lots. The vehicle was brought to an authorized Honda dealership for this issue. The dealer stated they could not replicate the symptom, diagnosed it as a low battery, and charged the battery. The issue persists. Failing to restart at a traffic light creates an immediate rear-end collision hazard and leaves occupants vulnerable in the middle of active intersections.

The malfunction involves the Auto Idle Stop / Auto Start-Stop restart system on my 2025 Honda Odyssey, including related battery, charging, starter, starter relay, brake switch, and Power Distribution Module components. The vehicle is available for inspection upon request. The vehicle has shut off while stopped in traffic, usually at a red light, and failed to restart normally. This has happened four separate times. This puts my safety and the safety of others at risk because the vehicle can become disabled in an active traffic lane or intersection, creating a rear-end collision hazard and blocking traffic. I took the vehicle to Hill Country Honda in San Antonio, Texas. I told the dealership the vehicle had stopped and failed to restart normally multiple times, and I provided video and pictures to the service advisor. The dealership stated the battery had run down because of the Auto Idle Stop system and charged the battery for approximately two hours. I was also told that if it happens again, the procedure may be to charge the battery again before moving forward with further diagnosis or repair. As far as I know, the dealer has not reproduced the failure while in possession of the vehicle. However, they were made aware of the repeated failures and reviewed the video/pictures I provided. I do not know whether American Honda has inspected the vehicle. It has not been inspected by police or insurance representatives. Warning messages appeared during the failure, including “System problem detected. Shift to Park” and “To continue to drive, depress brake pedal and push switch.” These appeared when the Auto Idle Stop system had shut the engine off and the vehicle did not restart normally. I had no clear warning before the first incident.

Mother single , sole support 4 babies and going through divorce needed a vehicle right away . Carvana rated this car 94 after its 150 pt inspection . It was noted that it was in an accident. Driving the babies on interstate the Pilar flew off, later on still on interstate , ck engine light came on, then steering warning, brake warning and sudden loss of speed . Car would not accelerate beyond 40 miles per hour . Day 32 car was taken to Honda where she found she could not open the hood. Car was then sent to Gerber A very quick look found upper tie bar was “buckled” the dipstick bent and radiator “floating” also impact bar was missing or bent … read Gerber report for clarification , told with hood misaligned and latch bent way back hood could possibly fly up and no front end protection in a collision. I am horrified and begging for emergency swap… they are claiming cosmetic … BUCKLED upper tie bar?? They are waiting on a more detailed report gambling with 5 lives or more ! I loaned this child7000 to help lower payments . I wanted her to have a safe vehicle to drive. This is undrivable yet she cannot afford rental.. why are they waiting for detailed when we know it was wrecked January 13 2026 and obviously NOT a 94 and safety inspection 150 was clearly fraud I would never have let her and those babies buy a wrecked piece of junk! I am scared EVERYTIME she gets behind the wheel. The amount of time is taking away from her new job. She is sole support please help emergency swap now

I was waiting at a stop light. The idle system kicked and the vehicle turned off, as expected. Upon lifting my foot off the brake, the vehicle failed to start and the car went into park. I was unable to restart the car after holding the brake pedal down and pressing the start button multiple times. After many failed attempts, I shut off the power to the vehicle, waited a min or so and restarted the vehicle. I then put the car in drive and continued thru the intersection. This was in a busy intersection and could have easily caused an accident, but thankfully it did not. This is the 3 time this has occurred with this vehicle.

The vehicle has an Auto Idle Stop no-restart/stalling issue. While stopped at a traffic light/intersection, Auto Idle Stop engaged. When attempting to proceed, the vehicle did not resume driving normally, shifted itself into Park, dashboard warning lights flashed, and the only way to move again was to turn the vehicle completely off and restart it. This left the vehicle disabled in traffic and created a serious rear-end collision/intersection hazard. The issue was confirmed by a Honda dealer on 06/26/2026 at approximately 11,804 miles. The repair order states that code P07AF was stored and that a snapshot showed a drop in cranking voltage due to a failing starter. The dealer advised that the starter must be replaced, but stated the starter is on severe backorder. The vehicle remains unrepaired. Honda customer service case #16464445. The vehicle is a low-mileage 2025 Honda Odyssey purchased new in April 2025 and used as a family vehicle to transport children. Prior Honda service records show maintenance was performed at approximately 9,800 miles, including a multi-point inspection, and the battery terminals/cables/mountings and battery condition were checked OK at that time. This appears related to NHTSA Engineering Analysis EA25004, “No Restart After Auto Start/Stop Engages,” involving 2018–2025 Honda Odyssey vehicles. The failed starter/vehicle is available for inspection upon request.

While the start stop feature is active, there have been several times where the van will not restart at a stoplight. In some cases, I have had to turn off the A/C, or other electrical systems to allow the car to restart. This has happened in traffic and caused several backups while I tried to restart the car. Took this van to the dealer and while they checked the systems they did not find any issued. As we progress through summer and into fall/winter, I do not want to have to worry about this in poor weather.
