2025 Honda Passport

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

The contact owns a 2025 Honda Passport. The contact stated that while stopped at a stoplight, the contact attempted to accelerate; however, the Start/Stop system failed to restart the engine. The check engine warning light illuminated, and there was an alarm sounded. The message "Shift to Park" was displayed; but the gear shifter failed to shift into park. The brake pedal was depressed with excessive force and waited for a while before the vehicle was shifted into drive and the vehicle was driven forward. The vehicle was driven to the desired destination and shifted into park. The dealer was contacted and an appointment was scheduled. The failure mileage was 30,600.

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.

The contact called Roadside Assistance, and the vehicle was restarted. The failure was a recurring failure. The screen was illuminated during the failure. The contact stated that while opening and closing the doors and pressing the Push-to-Start button to turn off the accessories, the vehicle operated as needed. The contact suffered emotional and mental distress from the failures. The failure mileage was approximately 10,000.

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

“Idle-Stop” feature stays on per factory installation. However when car is stopped and brake is released to proceed with acceleration, the feature automatically throws the transmission into “Neutral” and will not go forward, allow shifting of gears or shutting down the engine. This has happened numerous times in heavy traffic and creates a hazard. There is a button to depress to shut off the Idle-Stop but it must be done every time the car ignition is shut off then on. This is not a normal habit of long term drivers. After two inspections at the dealer and several phone calls Honda says they can not replicate the problem when serviced thus offering no solution. Searches online for assistance has revealed that this is a highly prevalent problem with Honda and Acura vehicles since 2019. As an elderly (over 75) driver with an excellent driving record it is creating a troublesome risk when driving.

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.

The car has failed to start on numerous occasions. The car has stalled due to the auto start/stop and the dealership told me that the battery needs to fail testing in order to replace under warranty. This is a major safety risk and the dealership said it’s a known issue but they can’t fix it. A recall needs to be put out immediately.
