2023 Honda Pilot: adaptive cruise control problems

Filed Sep 2, 2026 · Driver assistance, Steering · WA

While driving to work this morning. Rate of speed under 45 mph with no apparent issues. Suddenly warning lights on the dash lit up and steering became difficult. Three separate information warnings: Lane Keeping assist problem, electric power steering problem, adaptive cruise control problem. I was able to continue to drive the 3 miles to work. Had to use 2 hands and pull hard on the steering wheel to pull into the parking lot from the street. Actually had to stop the car, turn it off and restart it just to get into a parking space. Turned engine off twice, both times all warning lights came back on on the dash when I restarted the car. I only have 29,043 miles on this vehicle. It was unsettling to find myself in an unsafe situation today.

Description: While using cruise control at highway speed and winter weather conditions, the cruise control system suddenly and unexpectedly disengaged without adequate warning. The vehicle experienced rapid deceleration and I lost control, resulting in multiple spins, a near collision with a truck, and impact with a curb before coming to stop. The vehicle sustained damage. Fortunately no one was not severely injured. History and safety concern This is not an isolated event. I have experienced similar, unexpected cruise control disengagements multiple times over the past year while driving under varied conditions. Each event has created a significant safety risk. The sudden, uncommanded disengagement at highway speed caused abrupt deceleration and loss of control, which presents a severe hazard to vehicle occupants and other road users. I have reported the issue to the manufacturer and requested a full diagnostic investigation, system data logs, root‑cause determination, and remediation (I am requesting replacement or buyback if a defect is confirmed). I have asked the manufacturer to escalate to a senior case manager/remediation team and to preserve all relevant data and parts. Requested the federal safety agency actions Open an ODI safety defect investigation into this vehicle model/series and the cruise control/ADAS/cruise‑control module behavior. Request preservation and production of all relevant manufacturer data, including ECU/ADAS event data recorder logs, telematics, software versions, diagnostic records, and any field complaints or warranty claims related to cruise control disengagements. Evaluate whether this is a systemic safety defect requiring recall, remedy, or other actions, and consider requiring manufacturer owner notification and appropriate remedies (repair, replacement, buyback) if a defect is confirmed. Provide guidance on any additional evidence or steps I should take to support the investigation.

While driving the pilot warning alerts popped up that none of the collision detection, lane assist, cruise control, and seemingly all radar related systems were working. Additionally, the headlights turned off. We have brought this to the Honda dealer on now three occasions, and there doesn’t seem to be any understanding of why this is happening. On the evening of March 11 this issue happened again after the dealership having the car for a week to “fix “this problem and the lights turned off on an unlit road almost causing an accident. The car is again back at the dealer, who apparently is working with Honda again. I have seen this type of problem reported for other 2023 Honda vehicles, including the pilot, passport, and CRV on various Internet forums.

While driving home from a church event, I got a “Internal control module torque calculation” error on my dash. I pulled over to the curb and as soon as I stopped, more error messages appeared. Failure Brake System, Failure Anti-lock Brake System, Failure Hill Start Assist, Failure Adaptive Failure Cruise Control, Failure Lane Keep Assist, Failure Collision Mitigation, Failure Breaking System, Failure Road Departure Mitigation System, Failure Low Speed Braking, Failure Auto High Beam, Failure Parking Sensor, the check engine light was on and no AWD only FWD. I shut the car off and restarted it only to have all of the error messages reappear. I used my scan tool to clear the codes and drove it home. The next day, while driving my daughter home from school, the car shifted into neutral on its own then when the vehicle came to a stop it shifted into park and stalled and there was a transmission error on the dash. I had the vehicle towed to the dealership which reported 2 pages of error codes. The dealership reported that there was an issue with the gear selector unit due to liquid intrusion. They changed out the gear selector unit which at the moment seems to have rectified the problem.

I purchased my 2023 Honda Pilot on April 7, 2023. I had to wait for it to come in which happened roughly 2 weeks later. Within a month or so of having the vehicle while sitting at a traffic light I got 2 warning lights. One being the collision mitigation system problem see your dealer and immediately followed by adaptive cruise control problem see your dealer. I called the dealership to make them aware of the problem and was asked to make an appointment to bring my car in. Upon stopping and turning my car off and starting back up the warning lights were gone. I didn't think too much about it. In August when I had my car in for routine oil change they checked the issue and was unable to find anything. Around this same time my driver side front bumper started gapping. I was told that the clip was either not installed properly or was bent during manufacturing. (still waiting for that back ordered part to repair) In November while traveling with my niece and nephew again stopped at a traffic light EVERY SINGLE warning light started coming on. My dash was lit up like a Christmas tree and the lights were coming one after the other. I pulled over, not only would my car not turn off, my back liftgate would not work either. I was 4 hours away from home. I called the local Honda dealership where I was as I was in a panic. While on hold I was finally able to turn my car off by holding the start/stop engine button for several seconds. When I started my car again all of the lights were still on and lighting up one after the other. As I made my way to the dealership they all went off and all was normal again. I took my car to my local dealership once I got home. Dealership said they were not able to find much except the faulty camera sensors and Honda suggested to start there. (On back order) However in the meantime I was told that I should NOT TRUST ANY OF MY SAFETY FEATURES. My job requires a significant amount of driving and at this point I feel like I have gotten a lemon!!

Vehicle will randomly display multiple warning lights- usually starting with the braking system, until all warnings are triggered. This has happened about 10 times so far. Happens in a variety of driving situations. When car is parked, it then requires multiple presses on start button to turn the car off. Every time this happens the rear lift gate is completely disabled and unable to open. About 11/15/2023 I have a video of the errors I can provide- it is a large file and can’t be attached with the other photos. The error also occurred one time while driving at about 70mph using the adaptive cruise. There were no vehicles ahead, but one was approaching from behind- the vehicle brakes or the cruise controls caused the car to rapidly decelerate. I had had to push the accelerator to avoid causing an accident with the person behind me. I had the passenger take a photo of the dashboard warnings. About 11/3/23

Honda Pilot 2023 Elite shows 15+ error messages on the instrument panel. Messages indicate emissions systems, breaking systems, power steering and various risk mitigation systems experiencing problems resulting in reduced performance. Errors show up when the vehicle starts and are easy to reproduce. Dealer has looked at the vehicle 3 separate times. Problem occurs again in few days after dealer visit. Dealer based on the system error code diagnosed the problem with the fuel system. So far the dealer has replaced the high pressure fuel pump, injector relay, fuel pressure regulator and fuel rail pressure sensor. Dealer says when the vehicle starts the problem with the fuel system causes the electrical/computer system to go in safety mode; this makes onboard computers believe all systems are failing. Dealers' attempts (in consultation with manufacturer support) have so far not resulted in successful resolution of the problem. Without taking undue risk, I have personally tested some of the safety systems in errors indicated on the cluster panel to actually not work, e.g. lane departure mitigation system. Importantly, it feels vehicles braking distance has increased and steering is harder compared to when vehicles had no issues. All errors that are displayed are listed below. 1. Emission system problem, 2. Break system problem, 3. Electric parking brake system problem, 4. Break hold system problem, 5. Electric power steering problem, 6. Trailer stability problem, 7. Adaptive cruise control system problem, 8. Road departure mitigation system problem, 9. Vehicle stability assist system problem, 10. Hill start assist problem, 11. Trailer stability assist problem, 12. Hill descent control system problem, 13. Collision mitigation breaking system problem, 14. Road departure mitigation system problem, 15. Low speed breaking control problem.

At 850 miles on the odometer, the 2023 Honda Pilot ECU failed during normal operation of the vehicle on local roads, leading to a loss of power to engine transmission components, emissions systems, brake hold system, and traction control leading to reduced control and speed over the vehicle. The vehicle has been sent to the dealer for inspection of the OBD warning messages displayed. The driver was unable to operate the vehicle due to impaired speed, acceleration and braking capabilities that accompanied the ECU malfunction. The problem is currently being diagnosed by the dealer at the Keating Honda Service Center in Conroe, TX. The warning messages which appeared included the following while experiencing the ECU failure: Emissions System Problem. Avoid Heavy Acceleration and High Speed.
