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.

Upon accelerating from a stop, or at various speeds, the vehicle experiences a significant loss of motive power(pulling backwards) followed by an abrupt lunge forward. This hesitation occurs unpredictably and makes entering traffic or intersections extremely hazardous. This feels like a fuel delivery or transmission engagement failure. The last incident occurred on or around the afternoon of March 23. My vehicle has been examined at the dealership on multiple occasions for this same issue and each time I have been told that they are unable to replicate the issue and can not help me further unless they are able to replicate the issue.

Vehicle: 2022 Honda Pilot Elite AWD Mileage at first occurrence: ~30,000 miles Current mileage at worsening/repeatability of issue: ~48,000 miles My 2022 Honda Pilot Elite experiences a loss of propulsion during cold starts, most commonly after using remote start. The issue occurs when the vehicle is cold, shifted into Drive, and remains stationary for approximately 10–15 seconds. Under these conditions, the vehicle displays the message “Stop driving when safe. Transmission problem. See manual,” disengages the transmission, and shifts itself into Neutral. The vehicle will not move until it is shut off and restarted. This condition has occurred multiple times and is repeatable under the same circumstances. There are no other warning lights present, and restarting the vehicle temporarily restores normal operation. I reported this issue to my Honda dealer. The dealer contacted Honda North America technical support, who stated they are aware of this exact issue and the specific sequence of events that causes it. Honda advised that they do not consider this behavior a defect and declined to provide any repair guidance or corrective action. This condition results in an unexpected loss of drive capability and could pose a safety risk if it occurs in traffic or at an intersection. The issue can occur during normal vehicle operation and does not involve misuse of the vehicle.

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.

So this started as a loss of power when traveling down the highway, i would push down on the accelerator to pass and loss of power for at least 2 to 5 seconds. Now it is happening more frequent with normal driving. I believe this to be a safety problem.

About five weeks ago I decided I was going to take my kids to the park. Well, when we got there our vehicle wouldn’t go out of park and was stuck with a check engine light on and an emission light on. So, we had to tow it to Honda and they didn’t have a loaner vehicle for us while they were diagnosing the vehicle so we were without a vehicle for three days and then was called by Honda to come get the car that they cleared the check engine light and it’s drivable. Was told we would need a new transmission if the car check engine light comes on again. So, of course the light comes back on the next day. I don’t believe it needs a new transmission. No signs that it does. So I called the dealership and they wouldn’t answer , all departments went to voice mail. So, I called Honda corporate, and they wouldn’t answer next day thw dealership calls me asking me when I can bring the car back up there. So I brought it up there and got into a loaner this time for three weeks now. Was told last week our car is good to go and I can come pick it up and once I got there the check engine light and emission light was still on so they lied to us The corporate office won’t approve a good will transmission because of documentations that they should already have but don’t. And Duval Honda told us to bring the loaner back or they are gonna report it as an unauthorized use of the vehicle which we prolly put me in jail so I asked the gm at Duval Honda if he can at least extend it till the in of the week so we can figure something out since we have jobs and kids and no way of any transportation that he is gonna put us on the streets far as walking and he could careless and told us to get a rental car and if we don’t turn the car in then he will report it. So now we are car less. This car is a lease and we never missed a car payment and we had a car before this one which was a lease and never missed a payment as well. We are forced to walk while we still make car payments.

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.
