The steering wheel became extremely difficult for my husband to turn. Power steering went out on my 2025 Honda Pilot Trailsport. Numerous warnings were then displayed on the vehicle's dashboard screen, it was impossible to drive, and caused us to have to get towed. We had it towed to a Honda dealer for repair, where it was discovered that the steering wheel had more turns in one direction than the other, the shaft boot was misplaced, non-factory pins on the steering rack were noted, and the clock spring was stuck reading 508 degrees. Furthermore, the steering wheel rack gearbox had to be replaced following a steering angle sensor failure in my 2025 Honda Pilot Trailsport. This is a serious safety issue and should have never have happened in such a new vehicle. This incident not only put my family's lives at risk, but also everyone else on the roadway. Why did my vehicle that I bought brand new and have only serviced at Honda have non-factory parts?

On June 25, 2026 my 2025 Honda Pilot Elite (47,503 miles) upon ignition had every warning light in the system illuminate sequentially without any prior incident. I had never experienced any indication of malfunction, including warning lights or messages. The Emissions System Problem light remained illuminated on the dashboard and, after review of the Owner's Manual instructions to avoid heavy acceleration and high speed, I had the vehicle towed by AAA on a flatbed truck 75 miles to my home. The incident occurred during the evening and the next morning I drove the vehicle to Herb Chambers Honda of Seekonk, the dealer who has performed every service on the vehicle, including recalls. Of note is that the service team at the Honda dealer, specifically Malainne Costa, has been exceptional in addressing this issue. American Honda was consulted to determine the best plan for resolution. I understand that American Honda is trying to work through necessary adjustments with the new 2025 model year. One month after the incident, my vehicle remains at the dealer. I learned that the two cylinder heads in the engine block on my vehicle need to be replaced and those parts are still on backorder. Another engine component system may require replacement due to calcium buildup on the intake valves. I was assured that my driving habits were not a factor in this incident. My concern is that this incident occurred at a time when I was in a safe location and was able to await the arrival of AAA without worry about my personal safety. I bought the brand new vehicle in November, 2024 and it is obvious that I drive a significant amount of miles per year. I worry about the safety risk of other drivers having a similar experience in a less than optimal location especially since there was no indication of a problem prior to this critical incident. I share this incident in the spirit of exploring whether this is a systemwide problem that may result in a safety recall by Honda.

I contacted Honda America regarding a concern with my 2025 Pilot, which has just over 5,000 miles. The service light for the rear differential came on at the 5,000‑mile mark (I don't drive off-road, and my driving is 50/50 city/highway), even though the dealership indicated this service is not typically required until 10,000–15,000 miles. My goal was simple: confirm that there is no premature wear issue with the rear differential, and request that Honda cover the service if it is occurring earlier than expected. Instead, the experience was extremely disappointing. The representative repeatedly stated that he could not provide any technical information because he is a customer service agent. That raises an obvious question: if Honda’s own customer service cannot address technical concerns about a Honda vehicle, who exactly should a customer contact? He then informed me that he reached out to the dealership I use and spoke with the service manager, who said that “this could happen.” I already knew that from the dealer. Repeating the same vague statement does not add value, nor does it require involvement from a service manager or a manufacturer representative. It certainly does not address my actual concern about potential premature wear, nor does it justify the back‑and‑forth emails when no meaningful assistance was provided. To be clear, I am fully aware that dealerships profit from performing services—whether the vehicle truly needs them or not. That is precisely why I reached out to Honda America for clarification and support. Instead, I received no answers, no guidance, and no resolution. If additional information is needed, do not hesitate to contact me.

On 3/16/26 I attempted to accelerate and the vehicle experienced severe "bucking" and gear hunting hesitation before losing all drive power and stalling. Following the stall, the engine would not crank or "catch" despite multiple attempts. State Police arrived as I was in an unsafe location (blind on-ramp to highway) they called their tow trucks deeming it hazardous to wait as Honda Roadside Assistance would not arrive for an estimated 60-90 minutes. It was brought to the local dealership. After an hour from incident to inspection at the local Honda dealership, the vehicle powered on normally of which no codes showed and the vehicle started with no issues. The manufacturer and dealer state they cannot replicate the problem and found no historical or pending diagnostic trouble codes (DTCs). Despite the lack of codes, these symptoms are a direct match for NHSTA Recall Campaign 25V-031 (Honda Recall AL0) which was officially announced to address Torque Control Failures caused by the FI-ECU software. According to Honda’s safety report, improper programming in the fuel injection unit causes the engine to stall during "sudden changes in throttle opening"—which is exactly what I experienced. As of now, my VIN has not been identified on the current recall list. This loss of power during acceleration creates an immediate safety risk of rear-end collisions and leaves the driver stranded in active traffic.

Tonight, 11/8/2025 at 7pm MT, while traveling straight at 25-30 mph, power steering suddenly failed and vehicle reported that AWD failed with only front wheels powered. Many other failure warnings simultaneously appeared on dash (collision detection, LKAS, parking assist, etc). The vehicle is available for inspection upon request. My family's safety was put at risk. Sudden loss of power steering is very surprising to the driver, combined with the dash reporting a multitude of failure warnings all at once. If we had been driving on the freeway at speed or in the middle of a turn this would have been a very serious safety issue, easily leading to a collision given the sudden change in steering input needed. If traveling in snow or ice, losing AWD suddenly would also have been a serious safety issue. No one has inspected the vehicle since the incident, this just happened tonight. The vehicle has only 5,700 miles on it, was serviced by the dealer within the last couple hundred miles to repair all outstanding recalls, and I have had no other issues with the vehicle. There was no warning about and issues with the vehicle prior to this incident. The only thing out of the ordinary immediately prior to the incident is that my phone wasn't able to pair to the infotainment system (which never happens).

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.
