My 2022 Honda Pilot Black Edition (VIN [XXX], 62,900 miles) has multiple intermittent safety‑critical failures involving the transmission, acceleration, adaptive cruise control, and HVAC blower. These issues occur without warning and without diagnostic trouble codes. Transmission/Acceleration Failure: Most recent incident was XXX on Highway 71 during heavy traffic. The vehicle twice experienced rapid deceleration with no ability to reach a safety stop. RPM dropped below 1000, then spiked to 6,000–8,000 while the vehicle continued to lose speed. Acceleration returned only after several seconds. This also occurs during highway merging and uphill acceleration. Additionally, when disengaging cruise control and immediately pressing the accelerator, the vehicle loses speed, RPM drops abnormally low, then spikes before power returns. Adaptive Cruise Control/Honda Sensing Failure: On XXX the vehicle rapidly decelerated when a semi‑truck was beside me, despite no vehicle ahead. The week prior, while driving several states away, setting cruise at 70 mph caused sudden deceleration and cruise resetting itself to ~54 mph. These events resemble phantom braking and radar mis‑targeting. HVAC Blower Failure: During a long multi‑state trip the week prior, the AC blower (speed 3–4) intermittently stopped blowing for several seconds, then resumed at the same speed with no change to the display. These failures affect powertrain, forward collision avoidance, vehicle speed control, electrical systems, and cabin equipment. The dealership (Roush Honda, Westerville OH) cannot replicate the issues and reports no stored codes. These defects pose significant safety risks.

I was operating a 2022 Honda Pilot and had just made a left turn into a parking lot. I was slowly pulling into a parking space directly in front of a dance studio with a large floor-to-ceiling window. There were four children and a dance instructor standing inside near the window. As I was coming to a stop to park, my foot was on the brake. At that moment, the engine suddenly revved loudly and the vehicle accelerated forward unexpectedly without any additional throttle input. There were no warning lights, messages, or prior symptoms before this occurred. Despite braking, the vehicle continued forward and struck the exterior of the building. I was able to avoid the window area where the children were standing. The airbag deployed, and the front passenger side of the vehicle was damaged. The building was not structurally damaged, and no one was injured. There were no obstructions such as floor mats interfering with the accelerator, and there was no unintended pedal input. My foot was on the brake at the time of the incident. This appears to be a case of sudden unintended acceleration. The issue has not been reproduced or confirmed by a dealer or service center, and there were no prior warning signs before the event. The vehicle is available for inspection upon request. It has been towed to the body shop. The problem has not been reproduced or confirmed by a dealer or independent service center at this time. The vehicle was inspected by insurance and they did not total it. It is going to be repaired. The vehicle has been inspected by insurance representatives. The manufacturer has not inspected the vehicle at this time. I did not call police because I was not hurt, the kids were not hurt and the building only had a couple of scratches on the brick.

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.

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.
