2019 Honda Pilot

The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline.  The subject engine failures were analyzed as part of a Recall Query (RQ24013).  It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751.  Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation.  ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues.  To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation.  NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.

I have issues with my 2019 honda pilot front windshield camera. when the front-facing camera malfunctions, it simultaneously shuts down multiple Honda Sensing driver-assistance systems. The front sensor camera mounted behind the windshield fails or glitches, causing simultaneous failures in adaptive cruise control, automatic emergency braking, forward collision warning, and lane-keeping assist. The failure triggers a cascade of multiple warning messages (such as "adaptive cruise control problem" or "road departure mitigation system problem") i want Honda to repair it under recall.

This vehicle is equipped with Honda's Auto Idle Stop (AIS) system, which shuts the engine off automatically when the vehicle comes to a stop and is designed to restart it when the brake pedal is released. On XXX, while stopped at a light at approximatly [XXX], the engine shut off as normal, but failed to restart when I released the brake. The vehicle was inoperable for approximately one to two minutes while stopped in a busy traffic muilti-lane road at a light over an expressway, creating a serious risk of being struck from behind by other traffic. This is not an isolated occurrence, I experience this AIS no-restart failure on a regular/recurring basis, not just this one time. I am aware that Honda has issued service bulletins related to this issue (TSB 23-008, TSB 23-009) and that this defect is the subject of a certified class action settlement (In re Honda Idle Stop Litigation, No XXX). I believe this represents an ongoing safety defect that creates a real risk of a collision, particularly in higher-speed or higher-traffic conditions where a temporarily immobile vehicle is a hazard to itself and surrounding traffic. This vehicle has a rebuilt/salvage title (repaired and retitled prior to my purchase; it passed state inspection and is legally registered and roadworthy). When I contacted Honda about repair under the applicable service bulletins (TSB 23-008 / TSB 23-009) for this defect, I was told the rebuilt title status disqualifies this vehicle from that repair coverage. I am not seeking a warranty or cost remedy through this complaint, I am reporting this because it means an unknown number of vehicles with this safety defect are currently excluded from any manufacturer-provided fix, leaving the underlying no-restart hazard unaddressed on the road.

The car stalled in an intersection. The auto idle function had engaged when the car came to a full stop, but when i took my foot off the break it did not restart. It took a couple of tries to get it to restart, leaving my car in the intersection. This problem has been happening on and off since I bought it used in 2022. In May 2025, a Honda dealership near me made a valve adjustment and replaced the starter, which was supposed to have fixed the issue. However, it recently started occurring again.

My 2019 Honda Pilot EX AWD (VIN [XXX]) with approximately 80,000 miles developed a check engine light along with dashboard messages indicating an Emissions System Problem and AWD System Problem. The vehicle continued to drive normally, but the warnings repeatedly returned. Diagnostic code P0172 (System Too Rich, Bank 1) was present. The vehicle was inspected by an authorized Honda dealer on XXX which diagnosed failed fuel injectors and recommended replacement of the injector assembly at a cost of approximately $1,689. The failed components and dealer records are available for inspection upon request. While the vehicle has not experienced a loss of propulsion, I am concerned that a fuel injector defect could lead to engine performance issues, increased emissions, reduced reliability, or unsafe operating conditions if the condition worsens while driving. Honda has previously acknowledged fuel injector issues on certain 2017-2019 Honda Pilot vehicles and issued a warranty extension covering fuel injector repairs for eligible VINs. However, despite a dealer diagnosis of failed fuel injectors, I was informed that my VIN is not covered by the existing warranty extension. The vehicle has been inspected and the injector failure has been confirmed by a Honda dealership. Prior to diagnosis, the only symptoms were the check engine light and the Emissions System Problem and AWD System Problem warning messages. These warnings first appeared at approximately 80,000 miles. I am submitting this complaint because the failure appears similar to fuel injector issues already recognized by Honda, yet my vehicle is excluded from the existing warranty extension coverage. I believe NHTSA should review whether additional 2019 Honda Pilot vehicles outside the currently covered VIN population are experiencing similar fuel injector failures.
