The component that failed in both incidents was the vehicle’s wiring system, specifically wiring insulation that appears to be vulnerable to rodent damage. In the first incident, squirrels chewed through wiring connected to the fuel injector system, which triggered a check engine light and was repaired. In the second incident, squirrels again accessed the engine compartment and chewed through wiring affecting the braking system. This resulted in a sudden and unexpected loss of braking function. Yes, the damaged components should be available for inspection through the repair shop or service records, although I would need to confirm the exact location of the retained parts. Safety was significantly put at risk. During the second incident, the vehicle was occupied by multiple passengers, including minors. While approaching a red light, the driver attempted to brake and found that the brakes were not functioning properly. The driver had to shift the vehicle into park and use the emergency brake to stop, narrowly avoiding a serious collision. This created a high-risk, potentially life-threatening situation. The first incident was addressed by a mechanic after the check engine light appeared, confirming damage to the fuel injector-related wiring. The second incident was formally confirmed by a mechanic that the brake line was leaking from damage from, what they highly suspected and have seen in the past, a rodent . In the first incident, a check engine light appeared, prompting immediate attention. In the second incident, there were no warning lights, messages, or prior symptoms before the brake failure occurred.

Read full complaint
To Whom It May Concern, I am submitting this complaint to report ongoing engine and emissions system problems with my 2016 Honda Pilot that raise serious safety concerns and may be related to a broader defect currently under investigation. I purchased this vehicle from a dealership in April of 2024 and the issues began shortly afterward at approximately 67,000 miles. The vehicle currently has approximately 74,600 miles and has received regular oil changes and routine maintenance. The vehicle has repeatedly displayed emissions system warning messages and engine fault codes. It has experienced persistent engine misfiring even after a mechanic performed repairs on cylinder 1. In addition, the vehicle exhibits rough engine shaking during driving and idling, engine stalling, and rough or delayed gear changes continuously since 2024. Despite attempted repairs, the problems continue to occur to present. The stalling, misfiring, and unstable engine operation create a potential safety risk, particularly while driving at speed or in traffic. The rough shifting and loss of smooth power delivery further impact safe vehicle operation. Given the relatively low mileage, proper maintenance, and the recurrence of these symptoms, this does not appear to be normal wear and tear. I am aware that similar engine-related complaints have been reported by other owners of 2016 Honda Pilot vehicles and that this model year is included in an ongoing federal investigation into potential engine defects. I am requesting that this complaint be reviewed as part of that investigation and considered for further action, including possible recall or service remedy, to address the safety risks posed by these engine and emissions system failures. Vehicle Information: Make/Model: 2016 Honda Pilot Mileage: Approximately 74,600 miles VIN: [XXX] Thank you for your attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Opened Aug 20, 2025 · No close date supplied
Status: open (inferred from source dates) · Engine
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.

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.

RQ24013 · Engine Failure
Opened Nov 8, 2024 · Closed Aug 20, 2025
Status: closed (inferred from source dates) · Engine
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.
