No Restart After Auto Start/Stop EngagesOpened March 26, 2025, still open

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.the federal safety agency 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.

Acura TLX 2017, with only 112,000 miles. On [XXX], while the consumer was driving, the vehicle caught on fire. The consumer saw what appeared to be smoke coming from under the hood. The consumer stopped the vehicle immediately at a 4-way intersection, put it in park, and turned it off. The hood latch was open. When the consumer opened the hood, the engine compartment was on fire, and the car was engulfed in fire within seconds. Fire department and Police depratment arrived at the scene. The car was deemed a total loss, and the fire was determined to have started in the engine compartment. In May 2024, Acura stated that the connecting rod bearing needed replacement and that it was covered under the recall. However, 6 months after replacement, in October 2024, the knocking noise returned. The vehicle was brought to the Acura dealership, which noted at that time that the engine needed to be replaced, but the repair was denied under the recall this time. As required and recommended by the Acura Dealership, as well as by the recall, which noted safety risks, the consumer moved forward with having the engine replaced by the Acura Dealership, and the cosnsumer paid out of pocket. The vehicle was at the Acura dealership in Westwood for service from October 2024 until February 2025. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2017 Acura TLX stalled dangerously on the highway due to an unexpected fuel delivery failure, creating an immediate traffic hazard. Hiley Acura of Fort Worth diagnosed the vehicle with code P0087 (Low Fuel Rail Pressure) and confirmed it needs a new low-pressure fuel pump assembly for $1,540.62. They also pulled code P0430 (Catalyst System Efficiency) showing my front catalytic converter has failed, costing $2,461.77.The low-pressure fuel pump failure starved the engine of fuel, causing the highway stall. This fueling issue directly overheated and destroyed the catalytic converter substrate.This pump failure is the core subject of the Oliver v. Honda class action lawsuit. Honda previously issued a temporary corporate software update on my vehicle that deliberately altered how the computer reads errors, masking the physical fuel pump defect. This software update is the exact reason my car currently shows no open recalls on standard databases, despite still containing the defective, unreplaced factory hardware. This temporary software fix has now failed, resulting in a dangerous highway stall, and Honda is using the software-cleared VIN status to deny safety coverage.

My 2017 Acura was involved in a low-speed collision where it failed to stop in a timely manner, resulting in a total loss declaration. This vehicle had open safety recalls (including the fuel pump/rod bearing issues) that remained unrepaired for over 1.5 years. Despite multiple inquiries, the manufacturer failed to provide a repair timeline or remedy. I believe these unresolved defects directly contributed to the braking failure and subsequent safety incident.

I was driving on the freeway and I heard something explode followed by a clanking noise. The oil light and battery light came on simultaneously and I could not accelerate. I immediately pulled over and noticed that all the oil drained out of the car. When I got a chance look under the vehicle there was a hole in the oil pan. A mechanic said that it had happened from the inside. Possibly something from the motor broke off and shot out of my oil pan.
