2021 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.

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. Honda provided analysis of the alleged defect and stated that some customers possibly had an inadequate understanding of the AEB system and its limitations. However, many consumer complaints received by ODI allege that Honda dealerships were unable to reproduce the condition or state that Honda dealerships informed the consumer that this is considered normal AEB operation. To date, ODI has received a total of 106 consumer complaints of inadvertent activation of AEB in the subject vehicles.In total, ODI reviewed 475 reports involving vehicles with unique VINs that may relate to the alleged defect. Of the reports reviewed by ODI, three (3) allege a crash caused by the inadvertent activation of AEB and two (2) allege injury. This Engineering Analysis is being opened to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. Further, the scope of the investigation is being expanded to include assessment of model year 2023 Honda Passport vehicles.

The power door-lock system on my 2021 Honda Passport malfunctions while the vehicle is moving. When I make a right turn, the doors unexpectedly unlock, the interior dome light comes on, and I hear the door-unlocking sound. The doors do not physically open, but I must manually lock them again while driving. The problem occurs repeatedly during right turns. This malfunction creates a safety risk because the vehicle’s doors unlock unexpectedly while it is in motion, including when young children are passengers. The vehicle is available for inspection. I reported the issue to a Honda dealer, but the dealer requested a $199 diagnostic fee and has not yet diagnosed or repaired the problem. No crash or injury has occurred.

Incident

Jul 1, 2026

The engine experienced a catastrophic lower-end bearing failure at approximately 63,000 miles. The vehicle had been maintained according to the manufacturer's recommended maintenance schedule at the dealership service department. There were no missed oil changes. The failure occurred without any prior indication that a major internal engine problem was developing. The vehicle was taken to a Honda dealership, where the engine was disassembled. The dealer confirmed a lower-end bearing failure and reported significant metal debris inside the engine. The engine was determined to require complete replacement. A sudden internal engine failure creates the risk of an unexpected loss of power while driving, which can increase the risk of a crash, especially in traffic or at highway speeds. The failed engine is available for inspection through the servicing dealership if requested. The failure has been confirmed by the Honda dealership. No warning lamps or messages provided sufficient advance notice to prevent the failure beyond symptoms associated with the engine failure itself. I am submitting this report because I believe this may represent a manufacturing or design defect rather than normal wear and tear. I request that NHTSA investigate whether similar connecting rod bearing failures are occurring in other Honda Passport vehicles with this engine.

The vehicle experienced a catastrophic internal engine failure caused by connecting rod bearing failure. Prior to the failure, the engine developed abnormal internal knocking/noise, indicating bearing deterioration. The engine is currently available for inspection. While traveling approximately 55 mph on [XXX], the check engine warning light illuminated. Within about one mile, the engine rapidly lost power and developed a severe knocking noise. The sudden loss of power at highway speed created a serious safety hazard by reducing my ability to maintain traffic speed and safely maneuver the vehicle. I had my child in the vehicle, and both we and surrounding motorists were placed at risk of a collision while I attempted to move to exit traffic. The failure has been confirmed by an independent repair facility, Absolute Automotive LLC in Parker, Colorado. Their inspection determined the engine suffered internal damage due to connecting rod bearing failure. I have the engine replacement invoice, technician's diagnostic notes, and photographs documenting the engine damage. The vehicle has not been inspected by Honda. I contacted Honda to report the failure and request assistance, but I was informed there was no recall for the 2021 Honda Passport equipped with the 3.5L V6 engine and that Honda would not provide assistance unless a recall existed. Before the engine failed completely, the engine developed abnormal internal knocking/noise. While driving on [XXX], the check engine warning light illuminated, and within approximately one mile the engine lost power and produced a heavy knocking noise, rendering the vehicle unsafe to operate. I am submitting this complaint because a sudden internal engine failure resulting in loss of power at highway speeds presents a significant safety hazard and should be investigated.

Honda has a recall on certain vin numbers for the starter. My starter i was told to replace at a $2500 fee from reggie jackson honda in raleigh nc. I had to visit the dealership 3 times, they said its the battery, replaced the battery at my cost, now they said its the starter. They said there is a recall but my vin number was not included in the recall. The starter is worn out from the auto start and stop feature at stop lights. My issue is it will stop at a stop light and it wont start again then a warning comes on the screen about collision detection issue, then the warning goes away quickly and eventually i will get it to start but it is a safety issue that honda is aware of. I am asking honda to do partial credit on repair costs, but i dont understand why my vin number was excluded. The managers name was ruben lopez who informed me that the starter is causing issues, and sometimes its the battery, but that my vin wasnt covered. I just want my vehicle to not get stuck at after stopping in traffic when honda knows of the issue it should be covered for a lifetime warranty or recall. The stopping issue where it wont start again happens approximately 1 time per month, and seems to be in warmer weather but i cannot confirm this nor do i keep an exact log of when it happens. Thank you.

The multipurpose front camera on my 2021 Honda Passport failed without warning, causing mutliple Honda sensing safety systems to become inoperative. Warning messages appeared indicating failures of the collision mitigation braking system, adaptaptive cruise control, lane keeping assist system, road departure mitigation system, and other driver assistance features. The vehicle has not been involved in a front end collision and the camera failure was diagnosed by a Honda dealership as requiring replacement of the multipurpose camera assembly. This is a significant safety concern because the failure of a single component disables numerous advanced driver assistance systems that are designed to help prevent crashes. I have learned that similar front camera failures have been reported by owners of other Honda models using comparable Honda sensing technology. Because this failure affects critical safety systems and appears to be more than an isolated incident, I am submitting this complaint so it can be documented and investigated.

4th occurrence. Car fails to start. The instrument display reads: AUTO ENGINE IDLE STOP SYSTEM PROBLEM. Electrical system including radio, A/C etc were working. (Including the car alarm which begins honking the horn as soon as I open the door) Repeated attempts to start the car failed to do anything except to annoy anyone within earshot as the horn kept honking! Roadside assistance was not able to get the car started either so it was towed to the dealer. I've had the car into the Honda dealer for recalls but this problem has not been solved.

My 2021 Honda Passport Elite suffered cataphoric engine failure at 90,000 miles. The 6th cylinder bearing was missing when my vehicle was towed into Honda for diagnosis after my engine shut off while I was traveling 55 mph. I had no warnings for this failure including no engine noises and no check engine lights. I had to have a new engine put in my vehicle and Honda refused to cover the cost at 100% because they stated there were no open recalls at this time. I feel this is a manufacturer engine defect that is the same as the open recall defect Honda has on the 2017, 2018, and 2019 Pilots with the same 3.5-liter V6. The engine failure descriptions are exactly the same.
