My 2022 Honda Passport EX-L began experiencing intermittent starting problems in July 2025, including hesitation and clicking sounds. The battery was replaced in July 2025, but the problem continued. The main safety concern involves the Idle Start Stop system. When the engine shuts off while stopped at a traffic light, releasing the brake pedal does not always cause the vehicle to restart normally. At times it struggles or fails to restart, requiring a manual restart. This can leave the vehicle unable to move in active traffic and create a collision hazard. On September 1, 2026, at 61,133 miles, an authorized Honda dealer inspected the vehicle and confirmed the concern. The technician documented that it would not start or would struggle to restart after Idle Start Stop activation, found the starter weak, and recommended replacement. I paid $200 for the diagnosis. Honda Corporate advised that another software/system update was applicable and had not yet been performed; an earlier update was reportedly performed in 2023. Honda also advised that replacement starters were backordered/out of stock. The starter was repaired by an independent shop on September 10, 2026. Honda advised that the starter was not covered because the warranty had expired. I asked whether it would have been covered if the warranty were still active, and Honda stated it would not because the condition is not a recall. No police or insurance inspection occurred. The vehicle was inspected by Honda and serviced by an independent repair facility. Repair documentation is available. No warning lamp or message was observed. I request that NHTSA investigate whether this is a safety-related defect involving the starter, Idle Start Stop system, software, electrical system, or related components. I have invoices of the cost associated with the battery replacement and stater repair.

The starter motor on my 2022 Honda Passport failed, causing a complete 'no-restart' condition after entering Auto Idle-Stop mode. The vehicle previously received the mandatory PGM-FI idle-stop software update under Honda Service Bulletin 23-008, proving that the software fix does not protect the hardware from failing. The dealership diagnosed a failed starter but stated that my 2022 model is excluded from the 10-year starter warranty extension under Service Bulletin 23-009, leaving me to pay out-of-pocket for a known defect. I am filing this to support the ongoing NHTSA Engineering Analysis regarding Honda Auto Idle-Stop system failures, as the defect creates a dangerous stall risk at intersections

I own a 2022 Honda Passport . The vehicle auto idle-stop system has failed to restart at a traffic light. The vehicle shuts down and eventually restarts after several manual attempts and was able to be driven again. Typically, the vehicle stops in the middle of the road at the stop light and the engine shuts down. After a while, I was able to restart and drive without issues. In the meantime I am in a stalled vehicle in the middle of high speed traffic. The vehicle was taken to a dealer. The vehicle was diagnosed with having a starter failure and two burned out relays. I have never had a problem starting the vehicle when I begin a drive. The parts were repaired. The manufacturer was notified of the issue. The approximate failure mileage was 38,100. Failed parts were retained by the dealer.

I drive the car with the engine-idle-at-stop function disengaged. Several times when slowing down, but still moving, the car shifts into park; the AC and radio remain on. I have to press engine start to start the engine. Several other times when already stopped, such as at a red light or in traffic, waiting to make a turn, the engine shuts off and the car shifts into park. I have to press the engine start button to turn the car back on. I am getting honked and hollered at in traffic, and could easily be vulnerable to being rear-ended when my moving car suddently turns off ad stops running (winds up in Park). A non-dealer ran diagnostics and found No History of any error codes, and the system worked when they drove it. The day before the non-dealer had the car, it shut off 2 times in about 2 miles. He said the New battery is fine, the alternator is fine, and they do not know what to troubleshoot. No lights light up prior to the incidents, but they light up momentarily during it: it is the "Charging System Indicator" and the "Malfunction Indicator Lamp" that light up. The new battery is one week old and installed as per the owner's manual and was checked by a 3rd party today. These events have occurred with both the original and new batteries. All of this has been over the past few months, with most incidents - an escalation - the past couple of weeks.

The contact owns a 2022 Honda Passport. The contact stated that the idle stop/start feature had failed on multiple occasion while at a complete stop. The contact stated that the feature could be disabled; however, the contact would be burdened with the task of disabling the feature each time after starting the vehicle. Once the failure would occur, the vehicle would remain in neutral(N) and would not restart in neutral. The contact would be forced to place the vehicle into (P) and manually restart the engine; this had been a cause for concern as this failure would cause the contact to hold up traffic. The contact also express concern that the failure may lead to an accident. The vehicle had been taken to the dealer on multiple occasions to address the issue where he had been informed to turn off the feature, replace the battery, and have a battery reset performed on the vehicle. The contact had performed all three recommended remedies; however, the failure had persisted. The manufacturer had yet to be notified of the failure. The vehicle was not repaired. The failure mileage was approximately 90,000.

The infotainment screen on my 2022 Honda Passport is constantly blacking out or freezing up. In addition to no use of radio or GPS when this happens, there is also no backup camera or rear cross traffic warning. This creates a safety issue. The vehicle has been to the dealer twice. While they can see the problem, they indicated there's no fault code, therefore they don't know know how to proceed with a repair. I opened a case with Honda Customer Service but was told they couldn't do anything and I need to talk to the service manager at the dealer, or just go to a different dealer or Honda Service Center.

The starter failed to start the car due to what is described as a "frozen starter". A TSB exists for Honda where the problem is acknowledged, TSB 23-023. This left me stranded in the cold on 1/26 and 1/27. Many other drivers of similar vehicles have reported this problem in the past week. The problem is uniquely and disconcertingly dangerous as the problem impacts drivers who are in freezing conditions which can be inherently life-threatening if a known issue exists with a "frozen starter", this problem cannot be rectified by vehicle maintenance, for example, having a new battery or jump starter does not fix the problem. This problem strikes drivers in freezing and life-threatening conditions and is inherently unsafe and hazardous. The vehicle has not been inspected as Honda would not honor rectifying this issue for an "out of warranty" vehicle despite widespread concern. There were no warnings or messages prior to the problem. They first appeared in freezing cold after a precipitation event.

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.

Status: open (inferred from source dates) · Forward Collision Avoidance: Automatic Emergency Braking
On March 7, 2024, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24008) to assess reports of inadvertent activation of the Automatic Emergency Braking (AEB) system in model year 2019-2022 Honda Insight and 2019-2022 Honda Passport vehicles. The complainants allege activation of the AEB system with no apparent obstruction in the vehicle's path, resulting in rapid vehicle deceleration. Honda indicated that it is aware of a total of 412 reports that may relate to the alleged defect.
