2025 Honda Passport engine problems

Filed Nov 9, 2026 · Electrical, Engine · DE

Vehicle is equipped with Auto Idle Stop (AIS). When coming to a complete stop at traffic lights or intersections, the engine shuts off as designed. However, upon releasing the brake pedal, the vehicle fails to automatically restart. The engine stalls completely, leaving the vehicle immobilized in active traffic. This has occurred multiple times with increasing frequency over the past six months, creating a severe rear-end collision hazard. The most recent occurrence was 11/7/2026.

When the IDLE LOCK system engages and the engine shuts off, there is an intermittent issue where the car will not automatically restart the engine. The vehicle will go into neutral and require shutdown and restart before going into drive. This has resulted in extremely dangerous situations when it occurs on highways or in traffic. The Honda service department was unable to replicate this occurrence and recommended that I disable the Idle lock system each time I started the car.

I have a 2025 Honda Passport with just over 20,000 miles that is having the Start/Stop issue where the car will not restart primarily after it has been driven a few miles and the engine is hot. I usually try to turn this feature off, but if I forget, there is a good chance that I will be stuck blocking traffic. Very dangerous in high traffic situations. This has happened several times recently. I first started noticing the issue when restarting the car after a short stop and the engine was still hot. The starter seemed to pause before starting the engine. I took the car to the local Honda dealer, but they gave the car a clean bill of health. Since that diagnosis, I have been stuck several times in high traffic situations and also in parking lots where the car would not restart until it sat and cooled down. It is one thing to be in a parking lot and need to wait to start the car, it is a whole different situation to be in 8 lanes of traffic and not being able to start the car. I again took the car to the Honda dealer on 11/4/2026 only to be told that Honda is aware of the problem and they are working on it.

Vehicle Information: 2025 Honda Passport (Purchased in 2024, approximately 44,000 miles)Safety Defect Summary:The vehicle experienced a sudden and dangerous failure to restart during an Auto Idle-Stop event. While stopped at a traffic intersection, the Auto Idle-Stop system engaged and shut off the engine normally. However, when I lifted my foot off the brake pedal to accelerate, the vehicle failed to restart, completely stalled, and left me stranded in live traffic. The dashboard displayed error messages, and the vehicle required a mechanical inspection confirming a premature starter motor failure.Safety Risk & Hazard:This defect presents an immediate safety hazard. The engine stalling unexpectedly in the middle of active traffic intersections leaves the driver, passengers, and surrounding motorists vulnerable to rear-end collisions. Power steering and braking performance are compromised while trying to get the stalled vehicle safely off the road.Context for Investigation:This vehicle falls directly under the scope of the federal safety agency’s active Engineering Analysis (EA25004) regarding Honda Auto Idle-Stop restart failures. The premature failure of the starter motor at 44,000 miles is directly caused by the defective operational logic of the vehicle's automated stop-start system, matching the exact systemic defects documented in prior model years.

The Auto Idle Stop feature failed to restart the car after sitting at a stoplight twice this past week. The dealer (Frank Leta Hoda) diagnosed the problem as a "bad starter". I believe this falls under the active investigation EA22005 - No Start After Auto Start/Stop Engages. The vehicle is two years old with 40,378 miles at the time of reporting the problem to the dealer. I reported this to Honda Corp and was assigned case number 16619534 which is being reviewed. The two incidents happened without warning during drives when I had already pushed the button to disengage the Auto Idle Stop feature and was not expecting the engine to turn off at all.

I have a 2025 Honda Passport with approximately 22,776 miles. Over the past several weeks, the vehicle has developed a progressively worsening starting problem that appears to be heat-related. After the vehicle is driven normally and reaches full operating temperature, then is shut off and allowed to sit for approximately 10 to 30 minutes, the engine will sometimes crank very slowly and sound as though the starter is laboring to turn the engine. The frequency and severity have increased over time. On two recent occasions, the engine barely turned over before starting. After the vehicle sits overnight and cools completely, it starts normally and cranks smoothly. A second related problem occurs when the Auto Idle Stop/Start system is active. Both my wife and I have experienced very slow restarts at stoplights. More recently, the engine failed to restart automatically after Auto Idle Stop shut the engine off. I had to shift the vehicle into Park and press the engine START/STOP button multiple times before the engine finally turned over and restarted. This created a safety concern because the vehicle was temporarily unable to move while stopped in traffic. The vehicle was taken to an authorized Honda dealer for three full working days. The dealer reported that the battery, alternator, starter, charging system, and starting system all tested normal, and no diagnostic trouble codes were present. However, the dealer’s written repair description does not state that the vehicle was road-tested and then allowed to sit through the 10–30 minute hot-soak period that consistently produces the problem. The dealer stated that they allowed the vehicle to idle for an extended period and performed multiple starts, but this did not reproduce the conditions under which the problem occurs. I also opened a case with American Honda. Honda advised that they would not escalate the issue to engineering until the vehicle had been returned to the dealer one or two additional times. The probl

I have a 2025 Honda Passport. When the start stop shuts off car it will crank very slow or not start at all and have to wait a few minutes for started to cool. After I did some testing on my own then went to the dealer with an appointment, they confirmed this is a know problem with Honda. They did some testing and assured me that my starter is bad. No light or warnings until it would not restart at the stop light. The dealer pulled information off the cars computer and showed me a graph on how low the voltage goes below the threshold.

On August 14th I brought the vehicle to Coconut Point Honda after having the vehicle stall with the auto stop feature. At that time, I also noticed that the car had trouble starting at times. After being there for four days, I was asked to come pick up the vehicle. Yesterday, on August 27th, the vehicle stalled again, this time at a busy intersection. This narrowly missed causing my wife to get hit at high speeds. The car shifted itself to neutral, the battery and warning light came on, and a message saying “shift into park” appeared on the dash. Despite several attempts, the car would not restart until it finally sat a moment and then powered back on. The car was brought back to Coconut Point Honda where I again voiced the complaint and safety concerns regarding the vehicle stalling out and shifting itself into park.
