2024 Honda Pilot: adaptive cruise control problems

Filed Aug 27, 2026 · Acceleration, Driver assistance · TX

The vehicle came to a complete stop while attempting to enter the Highway. As I accelerated to gain speed, and the vehicle halted down to stop, all sensor warning systems started to light up on the dashboard: Adaptive Cruise Control, Automatic Emergency braking, Lane Departure Warning, Parking Collision Warning, Lane Keeping Assistance -- all sensors flashing simultaneously. As our vehicle stopped, the vehicles around us in the Highway had to abruptly stopped as well, causing a serious hazard, not only to myself and my family, but also the potential for a serious injury to other as well. This incident happened to us twice, and my passenger was able to record a video of the dashboard, as all the sensors were flashing and the vehicle switch to neutral on its own coming to a stop. We explained to the Honda dealership service department and after the second time, they kept the vehicle for service and it has been over (30) days since we had any update. The vehicle has been inspected by the dealership, and it is still there as parts are in back order, but there are not sure of what the real problem is. There were no previous warnings of this problem, the vehicle is a 2024 Honda Pilot Elite with 30,174 miles, and still under dealer warranty. This is the 3rd Honda Pilot I ever owned and never experienced anything like this before. My biggest concern is that if they do not fix this vehicle properly or if it is defective, my life and my family's will be in danger every time we drive it, as we do not know when it will decide to stop while driving.

The vehicle previously experienced a steering wheel locking issue and was taken to the dealer for repair. The dealer stated the issue was repaired on December 11, 2024. On February 24, 2026, while driving on a public street, the vehicle hesitated or jerked slightly during acceleration and then appeared to operate normally. After a few minutes, multiple warning messages suddenly appeared on the dashboard, and the steering wheel became extremely difficult to turn and effectively locked while I was driving. I immediately activated my hazard lights. I was unable to safely pull over because the steering wheel would not respond properly, which placed me and other drivers at risk. I had to continue driving slowly until I found a side road where I could safely stop. I turned the vehicle off. When restarting, the warning messages reappeared. After several minutes, the warning lights cleared, and the steering wheel was no longer locked but felt loose and unstable ("wobbly"). I cautiously resumed driving. After several minutes, the steering began to feel normal again. The following warnings were displayed: Hill Start Assist problem, Trailer Stability Assist problem, Hill Descent Control problem, Adaptive Cruise Control problem, Lane Keeping Assist problem, Collision Mitigation Braking System problem, Road Departure Mitigation problem, Low Speed Braking Control problem, Auto High-Beam problem, Electric Power Steering system problem – Steering Assist Not Available, and "Stop. Steering assist reduced. Stop driving when safe." The failed component appears to be the Electric Power Steering system and related driver-assistance systems. The vehicle is available for inspection. The problem was previously addressed by a dealer but has reoccurred. No prior warning lights were present before this incident. The failure occurred suddenly while driving.

Incident Description: While traveling at 45 mph with Adaptive Cruise Control (ACC) active, the vehicle experienced a "phantom braking" event triggered by high-contrast shadows on the roadway. The Collision Mitigation Braking System (CMBS) incorrectly identified a shadow as a physical obstacle and abruptly applied the brakes in a clear path of travel. I was forced to manually override the system by applying the accelerator to prevent a potential rear-end collision. Safety Risk & Technical Context: This defect is repeatable under specific lighting conditions and occurs across multiple speed intervals (35–45 mph). I believe this incident is directly related to the ongoing the federal safety agency Engineering Analysis (EA24002) regarding inadvertent AEB activations. Furthermore, recent Service Bulletins (such as MC-11024251-0001) regarding Front View Camera and Radar Sensor updates suggest a known failure in the system's ability to process high-contrast environmental data. Conclusion: My local dealership failed to investigate the complaint. The sudden, unexpected deceleration poses a severe safety risk to the vehicle's occupants and following traffic. I request that the federal safety agency formally notify Honda of America regarding this recurring ADAS failure to ensure that my VIN is prioritized for the necessary sensor alignment and software enhancements.

Driving down a 4 lane highway in Alabama, warning lamp came on stating “ STOP Steering assist reduced. Stop driving when safe”. Multiple other warnings lights came on—-Brake system, steering system, cruise control, lane departure, stability assist system, hill assist, trailer stability assist system(see multiple photos attached). When it was safe to do so, I pulled over…the steering was VERY difficult to manage. If I had to make a turn in traffic or had to make a sudden turn to avoid an accident, I would not have been able to do so as there was NO power steering. I turned the car off, let it sit for several minutes and the Steering Assist warning was off and I appeared to have power steering but several others lights were still on. Took the car the the closet dealer and only code found was a Low Voltage Code but nothing repaired as all warnings lights were off by then.

My Honda is having strange, intermittent issues with a plethora of things. I have taken it to a diagnostic specialist who worked with a phone mechanic and noone can tell me what is going on. My car will fully shut off at stop lights randomly, so I have to turn off the auto-idle feature every time I drive. Sometimes my power steering cuts out and my wheel locks and unlocks and my computer screen shuts off when this happens. I have to shut off and start my car for it to work again. Other times, all of my automated safety features stop and I get a huge slew of messages telling me that my lane assist, automatic hill braking, and a ton of other automatic safety features don't work. My car can't lane assist, do adaptive cruise control, use the backup camera, or anything. It goes away if I stop and restart my car a bunch. I also had a seatbelt alarm that was going off repeatedly with no reason. The dealership turned off the alarm. I am having a lot of issues with this car that makes me question if it is a lemon. I see other new Pilot owners mentioning issues with power steering shutting off and it's a huge safety risk. Noone knows whats wrong or how to fix it so what do I do? This happens intermittently, randomly, and recurrently since June.

I believe that there is a safety issue with the design of the adaptive cruise control on the 2024 Honda Pilot. The vehicle applies the brakes at about 1 mph over the selected speed. It is especially aggressive when topping a hill. The gas lets up, but due to the vehicle inertia, the car slightly accelerates, then braking. I believe that this action is unsafe for several reasons. It slows the vehicle several mph below the set speed causing cars behind me to swerve or come close to me. No human driver would apply the brakes in that situation. It also appears to irritate those same drivers. I’m glad that none of them has a weapon so far. It also applies the brakes going downhill on the interstate highway. This occurs at any speed below 55 mph. This also makes it look like the driver is continually tapping the brakes, when no one normally would. I suspect that there may be extra brake wear. My family asks what is going on with the car because of the aggressive braking. I previously owned a 2018 Honda Pilot with adaptive cruise control. It used transmission downshifting to slow the vehicle. I admit that there were some over speeds, but nothing serious. The 2024 Owner’s Manual states that downshifting is also used, but I’ve only seen the brakes used for over speed control. There are no user selectable adjustments to the system. I am getting used to this (feature, not a bug) by clicking off the cruise control whenever the conditions are close for a brake activation. This causes me to pay more attention to monitoring for those conditions, rather than the actual driving and traffic scan. I suggest that the system use downshifting followed by brakes after a 3 or 4 mph excursion from the set speed.

Vehicle has many fault codes that will not clear. Took to dealership and the state they believe its a wheel speed sensor and vehicle is safe to drive. Flashing warnings include AWD system problem, electric parking brake problem, brake system problem, brake hold system problem, electric power steering problem, antilock brake system problem, vehicle stability assist problem, hill start assist problem, trailer stability assist problem, hill descent control system problem, adaptive cruise control problem, lane keep assist problem, collision mitigation system problem, road departure mitigation system problem, low speed braking problem, auto high beam problem, parking sensor problem, antilock brake system problem, as well as drive mode change unavailable, rear hatch will not open, drivers seat will not automatically move into position once vehicle is started, vehicle will not shut off without having to hit the off button numerous times, and vehicle is not auto shutting off after the 10-15 min timeframe. Dealer states they have ordered the part and is currently on back order. Was told Honda does not provide loaner vehicles for warranty work. Seems strange that a wheel sensor could cause so many errors and shut off all safety features, brakes and drivetrain of the vehicle.

The vehicle was purchased brand new on Feb 1st 2024. While driving on the highway on Feb 5th 2024, with only 105 miles on the odometer, and no prior warning messages/lights, many warning messages were suddenly displayed on the dashboard, repeating one after the other, instructing that various safety features were disabled, displaying: "Parking brake not available", "Brake system problem", "Brake performance may be reduced", "Brake hold system problem", "Anti-lock brake system problem", "Vehicle stability assist system problem", "Reduced traction and handling", "Electric power steering system problem. Steering assist reduced", "Hill start assist problem. Vehicle may roll upon brake release", "Trailer stability assist system problem", "Hill descent control system problem", "Adaptive cruise control system problem", "Lane keeping assist system problem", "Collision mitigation braking system problem", "Road departure mitigation system problem", "Low speed braking system control problem", "Auto high beam problem", "Parking sensor problem". In addition, after coming to a full stop and shifting to Park, (or, turning off the car) the tailgate would not open regardless of how we tried (dash button, remote key, tailgate handle, foot swing). Also, the car would not turn off after pressing the On/Off button. The button would need to be pressed repeatedly to turn off the vehicle. All of these safety systems and functions were disabled at the same time without prior warning while driving at highway speeds. The Honda dealer confirmed the problem, inspected the vehicle, and concluded a faulty ABS control module is to blame. We know of one other 2024 Honda Pilot owner in our neighborhood who experienced the same issue, which makes it likely that this is a common problem. Honda should have designed redundancies to prevent sudden simultaneous failure of so many safety systems. Honda should recall all affected vehicles to replace faulty ABS control modules before people are hurt.
