2025 HONDA ODYSSEY Complaints

The idle stop system frequently fails to restart the car after shutting down the engine at a stop light. In some cases the car is difficult to restart using the starter button. In other instances the car restarts and then dangerously lurches forward.

While waiting at a red light with foot on the brake, the auto idle stop system shuts off the engine but fails to restart it when the foot is lifted off the brake, causing stalling. The vehicle has to be put in park and turned off completely and restarted before it will drive. This has happened twice, once on 5/1/26 and today on 5/7/26.

Back passenger side window broke while driving with no evident cause. Speed was between 25 and 35 mph, no other vehicles were present nearby, and no pedestrians were in the area.

The car intermittently struggles to restart or dies and will not restart after stopping at a stoplight or stop sign due to the auto stop start. Even when the engine restarts after a stop, of often sounds like it’s struggling. The car has been taken into the dealership multiple times and the battery has been replaced twice. Honda dealer claims there’s no known issue despite numerous complaints online and report of a federal investigation into this issue with many Honda Odysseys and specifically the 2025 model year.

The vehicle's Auto Idle Stop system shuts off the engine at stop lights and other low-speed stops and, on multiple occasions, fails to restart, and the AIS disable button is sticking. We disable AIS every single time we drive the vehicle, and on multiple occasions the button has re-engaged itself mid-drive, meaning the safety hazard cannot reliably be avoided even with the workaround Honda recommends.

I was driving on the street about 15 miles per hour when the car sensor sensed something in front of my car and stopped automatically when there was nothing in front of me. Almost caused a rear-end accident, luckily, the car behind was able to stop

When I am stopped at an intersection, my 2025 Honda Odyssey will often automatically stop the engine as part of its auto idle feature. However, three times in the last month, my car has stalled when it's time to start the engine. One time was on a highway when I was stopped at a light, and cars started honking and driving around me (including on the shoulder). Only after I turn the car off and turn it back on, can I start driving again.

There is suspension noise coming from driver side when driving in low speed (10-30mph). You can feel it when turning and accelerating slowly. It started around 9000 miles after first service of the car. There was no noticeable noise before. Reported to dealer but they cannot fix it and told me everything looks normal.

The Auto Idle Stop feature caused the engine to shut down twice, both times at a stoplight

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.
