2025 HONDA ODYSSEY Complaints

Would die at lights and so on, starter replaced and its started doing it again. Dies at lughts, stalls out at stops then will hesitate to start again and will throw itself forward making a clunky noise

This vehicle will randomly turn these features on and instead of keeping you in your lane pull you off the road, I have had to pull over to turn the vehicle off to get it to turn off

The vehicle will slam on its brakes with nothing around it. This has happened more times than I can count now and has almost caused us to wreck on multiple occasions

The van got stuck in park after backing out of a parking lot. Changed to drive but gear shift back to park. Have to restarted the car twice. People were honking nonstop. This is not safe.

The Auto Idle Stop system intermittently fails to restart the engine after the system shuts the engine off while the vehicle is stopped. When this happens, the vehicle remains disabled and I have to completely restart the vehicle before I can continue driving. This has happened twice while stopped in highway traffic. On both occasions, traffic began moving while my vehicle failed to restart, creating an immediate crash risk and nearly resulting in collisions from vehicles behind me. The problem is intermittent. The vehicle has previously been brought to a Honda dealership for this concern, but the failure continues. I have contacted the dealership again and have also contacted the manufacturer regarding the issue. There were no consistent warning signs before the failure. The problem occurs after the Auto Idle Stop system activates. Because the vehicle may fail to restart unexpectedly in active traffic, I am concerned that the condition presents a serious safety risk to the occupants of the vehicle and surrounding motorists. The vehicle is available for inspection upon request. This condition appears consistent with NHTSA Engineering Analysis EA25-004 involving Auto Idle Stop no-restart complaints on Honda Odyssey vehicles.

The vehicle experiences a sudden and complete engine stall while at a complete stop in traffic (such as a red light) due to a failure of the Auto Idle Stop (AIS) system. The engine shuts down smoothly as intended by the fuel-saving feature, but fails to restart when the brake pedal is released or the accelerator is pressed. The vehicle drops into a total shutdown state, requiring the driver to fully shift into Park, switch the ignition completely off, and manually press the Start button to restart the engine. No warning lights, error codes, or dashboard messages appear before, during, or after the failure. This creates a severe safety hazard by leaving the vehicle unexpectedly stranded and unresponsive in active intersections.

My vehicle has failed to restart numerous times at stoplights with the auto start engaged. It also failed once when it was disengaged. It also stalls to start on initial start quite often. Even when it is disengaged, upon stopping my vehicle makes a type of quiver in the engine that sounds like a stall or like it is about to cut off. It usually evens out after 5-10 seconds. I had people drive around me, in heavy traffic, after a major fail at a red light. I had an aggressive drive pass around me quickly at another incident at a smaller redlight intersection. I have had it cut off, with my family, over 50mls away from home. A dealership replaced my battery that was under warranty. I was told there were no other issues and to keep my auto start disengaged while driving. I'm not sure that is my safest option at this point. I am extremely concerned it will happen at an intersection and I will roll into traffic with my family.

My 2025 Odyssey stalls. The engine will turn off when I am stopped and will take at least 2 retries to get the engine to turn over. Once I was at a stop light on an interstate off ramp when it stalled. Once I was at a stop sign when it stalled. Twice I have been unable to start it at a store. I will settle the brake & push the start button & nothing will happen. I will try again. I have to take my foot fully off the brake, wait a few seconds, & try the steps again. It eventually starts, but I'm afraid that someone will hit me and hurt my children or myself as I'm a sitting duck.

The contact owns a 2025 Honda Odyssey. The contact stated that while coming to a complete stop at a red light or a stop sign, the vehicle stalled and shut off unintendedly. There was no warning light. The vehicle was restarted. The manufacturer was notified of the failure and stated that there was an ongoing investigation associated with the failure. The vehicle was not repaired.

The idle restart function causes the van to shut off completely when at stop lights in heavy traffic. It does not immediately restart and we have to sit in traffic while folk are honking at us to go. It doesn’t do this every time, but has happened 3 times in the last 3 months.
