“The vehicle experiences phantom braking while driving, where the Collision Mitigation Braking System (CMBS) activates without warning even when there are no vehicles or objects in front of me. The vehicle suddenly brakes on its own, creating a major safety hazard and risk of rear-end collisions. The issue has happened multiple times during normal driving at different speeds. Warning lights related to the collision mitigation system and passenger airbag system have appeared intermittently. The blind spot monitoring system has also failed to properly detect nearby vehicles at times. The vehicle was previously taken to the dealership/service department and remained there for an extended period for inspection and attempted repairs, but the problem was not fully corrected. After getting the vehicle back, the same symptoms and braking issues continued. This issue puts myself, my passengers, and other drivers at risk because the vehicle may suddenly brake unexpectedly in traffic.

When I started my 2022 Honda Pilot Special Edition (VIN: [XXX] ) in a parking lot, the vehicle immediately behaved abnormally. As I attempted to turn into a space, the car unexpectedly accelerated and moved in an unintended direction. Despite pressing the brake pedal firmly, neither the standard brakes nor the automatic braking system responded. Shifting into Park did not stop the vehicle, and the transmission did not engage to hold the car. The vehicle continued moving through the parking lot, striking property and other vehicles. The entire event felt like a loss of braking and control, with both the brake system and gear selector failing to function as intended. This was a sudden and dangerous incident that could have caused serious injury. The Honda dealer has confirmed there are no open recalls or campaigns for my VIN, but the event aligns with reports of unintended acceleration and brake failure in other 2022 Honda Pilot vehicles.

Case 11655023 Hello, I need your help. I spoke with Honda and was told they would buy back my truck and someone would contact me. Mrs. Briana called and said I had to keep taking the truck to the mechanic as many times as needed. I explained I had already taken it 8–9 times, but she said it didn’t matter and that I should take it to another dealer. I had already gone to the Mission Valley dealership, showed the mechanic photos and videos, and he agreed something was wrong. I left the truck for 3–4 days, but they only changed the start button. I asked about the brakes, which were making noise, and was told it was “normal.” I insisted on getting them fixed, but they said if parts weren’t broken, Honda wouldn’t replace them. I spoke to the manager, who drove the truck with me and said they would adjust the brakes and fix the faulty fuel sensor. I brought it back on Wednesday, received a service receipt, but when I tried to leave, the truck wouldn’t start. I showed the manager a video of the issue, and he said they would fix it. I returned on Wednesday, left the truck again, and on Thursday a worker called saying the truck had no issues. I reminded them the manager had promised repairs, and they said he would call me. On Friday, I was told the truck had “bad luck,” nothing was wrong, and I should pick it up — or go to another Honda if I wasn’t satisfied.

My name is [XXX] , I am the owner of a 2022 Honda Pilot, and the safety of this vehicle is now of great concern to me. My vehicle has done up to 35,000 mileages. On Friday, [XXX] as I was driving on the highway, this vehicle suddenly stopped without warning. All the lights on the dashboard came up and I received 5 messages indicating that the following had problems: Emission System, Vehicle Stability Assist (VSA), Electric Power Steering, Transmission System, and Adaptive Cruise Control. This is a very dangerous and life-threatening hard stop that occurred in the middle of the highway, and I had to tow the vehicle to the DACARS Honda Dealership in Bowie, Maryland. I must state that my service history is up to date as of the time of this incident. The dealership carried out a diagnosis and confirmed all the problems from the messages that I received and agreed to fix them because the vehicle is still under Manufacturer's Warranty. I am really concerned about the safety of this vehicle and the lives of other owners and road users who may not be as lucky as I was on [XXX]. I recommend a very detailed safety evaluation on this Model of Honda and if possible, immediately instruct the replacement of all the safety problems/parts listed above pending the outcome of this investigation/evaluation, and ultimately instruct a recall of this model of Honda. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
