Over the past two weeks we have been experiencing issues with the Auto Idle Stop device on my 2025 Honda Passport. This has resulted in being temporarily stalled at several busy intersections. I have reported this issue to a Honda dealership where the issue was verified and it is scheduled for a Starter replacement when the part is received from back order.
Description: The vehicle suffers from an intermittent and dangerous "no-restart" defect involving the Auto-Idle Stop (AIS) system. When the vehicle comes to a complete stop and the automated stop-start system shuts off the engine to conserve fuel, the engine frequently fails to automatically restart upon release of the brake pedal. This results in a sudden, unexpected loss of engine power and complete immobilization in live traffic or intersections. This exact failure mode is the subject of an active federal Engineering Analysis by the National Highway Traffic Safety Administration (NHTSA EA25004, covering ~2.2 million Honda and Acura vehicles). Prior manufacturer service bulletins and part-replacement attempts have proven ineffective at permanently resolving the hazard, creating an ongoing and unacceptable collision risk.
For several months before the failure, the Auto Idle Stop (engine stop-start) system became progressively slower to restart the engine after stopping. Each restart sounded sluggish, as though the starter was dragging, and the vehicle would remain stopped for several extra seconds before moving. This occurred repeatedly at traffic lights and other stops creating a safety concern as drivers behind me expected my vehicle to begin moving when traffic started. The unexpected delay increased the risk of being rear-ended or causing confusion in traffic. The failure eventually became complete. While stopped on a two-lane road waiting for another vehicle to turn left into a driveway, the engine shut off as expected with the Auto Idle Stop system engaged but did not restart when I released the brake. Instead, the vehicle entered what appeared to be a neutral state and could not be driven. I was unable to restart the vehicle for several minutes, leaving it disabled in the travel lane while other vehicles had to drive around it. This created a safety hazard because the vehicle was stranded in an active roadway. The vehicle had not previously displayed any warning messages related to this condition. Looking back, the progressively slower and dragging engine restarts appear to have been warning signs before the complete failure to restart. The vehicle is scheduled for inspection the Honda dealership this week. The failed components should be available for inspection if requested.
Got to red light, auto stop idled down car, when going to move car shut off and stalled out. Also happened two times in a drive thru. All times messages popped up auto stop interruption and vehicle in accessory mode
The Idle-Stop feature is malfunctioning, the vehicle is equipped with an "Auto Idle Stop" feature that has a dangerous defect. The engine frequently fail to restart after shutting off at stops, unexpectedly leaving the driver stranded or immobile, with the risk of being hit from behind by incoming traffic.
25 Passport Black edition only 27k miles at a stop my vehicle won’t start back up kicks it from D to N will start flashing to put in P. Vehicle will not start back up until I turn off and back on. The second time it did this it wouldn’t even start back up battery light flashing. I try to remember to turn that stop/start button off. Very dangerous. Went to dealership. Says they can’t do nothing unless warning are on at the time of check. 4/24 was the second time this has happened. When I start the passport it’s like it has troubles and not wanting to start. Lights will start flashing braking system and blind spot all the safety feature lights. Something is wrong with these passports.
car transmission issue not getting enough power while putting foot on gas pedal rpm goes upto 5k for getting speed not shifting gear properly
Vehicle has stalled multiple times at stop lights after the automatic engine stop engaged. Vehicle will not restart when accelerator is pressed and has to be placed in park before the engine can be started again. This happened (4) times on the most recent trip yesterday 3/19/2026.
The car has an auto stop capability that engages during red light stops (etc.). The auto stop function automatically engages every time you start a new trip. Unfortunately, the car occasionaly fails to restart and displays emergency alerts. To restart the engine, the car must be put back into Park. This essentially results in the vehicle stalling out and it creates a significant safety risk. It happens on a somewhat regular basis. In addition, when starting the vehicle, it sounds as though the starter is having a difficult time powering up the engine.
I am submitting this report regarding a serious safety issue with my 2025 Honda Passport related to the auto stop/start feature. When this feature is enabled, the vehicle frequently struggles to restart smoothly after coming to a stop. The engine often hesitates and sounds as if it may not start at all. On September 26, 2025, the problem escalated into a complete failure. While turning left at an intersection, the auto stop/start feature engaged, shutting off the engine. When I attempted to accelerate, the vehicle failed to restart and became fully disabled in the middle of traffic. This created an immediate and significant safety hazard. Law enforcement was called to the scene, and a tow truck was dispatched. However, due to incorrect information and safety concerns, I did not proceed with the tow. Fortunately, the police were able to jump-start the vehicle, allowing me to drive it directly to the dealership. The dealership confirmed that there is an issue but has been unable to replicate the complete failure. They have performed two battery tests, both of which returned normal results. While they acknowledge the problem, they have not been able to formally diagnose it. I have since learned that similar issues and recalls have been reported for earlier Honda model years, suggesting that this problem may still exist in newer vehicles, including the 2025 Passport. Since the incident, I have been disabling the auto stop/start feature every time I drive in order to avoid being stranded again. However, hesitation during restarts continues to occur daily when the feature is active. Given the severity of the safety risk and the inability of the dealership to diagnose or resolve the issue, I am requesting that Honda conduct a formal investigation into this malfunction and take appropriate corrective action. This issue should be fully addressed under warranty, as it directly affects the safety and reliability of the vehicle.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
