2025 HONDA ODYSSEY — Problems, Recalls & Safety Data

My 2025 Honda Odyssey features a standard Auto Idle Stop system designed to improve fuel efficiency by shutting off the engine when braking to a stop. While intended to restart upon releasing the brake, my 2025 models have reported issues with failing to restart or stalling.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The failure had occurred while driving from a stoplight, while the auto idle system was enabled. There was no warning light illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The dealer was made aware of the failure. The contact was advised that a diagnostic test was needed to determine the cause of the failure. The failure had occurred three times; however, the failure had not reoccurred after turning off the vehicle. The dealer informed the contact that the failure might not be duplicated. The manufacturer was not made aware of the failure. The failure mileage was approximately 12,549.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving approximately 40 MPH, the vehicle experienced a loss of automotive power. The failure was intermittent. No warning light was illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 12,000.

The idle stop feature sometimes fails to reengage / restart the engine. One time, the van failed to restart and the vehicle completely locked up while I was in an exit ramp to the freeway. I had to turn the van off and turn it back on to get it to shift into drive and go. Similar events have happened a number of times, since the summer of 2025. We have taken it to the dealer twice now, and have been told to "monitor" it. We found the NHTSA report #EA25004 and believe this is the issue we are experiencing. Occasionally, the idle stop will restart, but it's a very violent restart (car sputters and chokes in restart, sounds like it might stall). The car will make a warning light flash and give an error message, but it always clears too quickly to read it.
