Problems started showing on car a week ago. Tested battery and it was not holding a charge. Replaced battery and problem still persisted. Car is now at dealership and they are quoting close to $2000 due to failure for internal windshield camera. Car has right over 78k miles. This is a safety issue.

On multiple occasions the hazard mitigation system has picked up on hazards that aren't there causing rapid braking AND steering over correction. Currently the button on my vehicle that has an image representing the ability to turn the system off doesn't appear to be connected or working. I have always left the system on as it felt "safer" when I bought the vehicle new. I haven't even tried to turn it off until recently when the system seemed to start malfunctioning. Today (11/19/2025) while traveling the interstate for a routine doctor appointment the adaptive cruise control randomly shut off as I was driving multiple times. If I changed lanes and a vehicle was in front of me the adaptive cruise control would just shut off with no warning or alert rather than adjust the speed as the system is designed to do. Once I exited from the interstate at a traffic light (green, turning left) the lane assist overcorrected, the steering wheel got stiff and it was jerked into the other lane almost causing a collision. This is very concerning as I was very fortunate not to have been involved in a collision today thankfully the other driver was paying attention and evaded. Each incident there has been ZERO warning. There have been a couple times recently where the system randomly fails and says there is a problem, but within minutes come right back on and operates properly until it randomly malfunctions again. This has occurred very sporadically over the past 6 months with incidents rapidly increasing over the past 3 days to the point I am very nervous to carry my children in this vehicle any longer. This vehicle was purchased as the primary vehicle for our family and our purchase was strongly influenced by Honda's "safety", but now that's very much in question as I understand many other Honda owners are experiencing the same Honda system issues. We are in the process now of having it scheduled with Honda, but this should not be acceptable from any manufacturer.

Vehicle is setting multiple faults for ADAS system. LKAS, ACC, collision mitigation system, auto high beam lights inoperable. Forward facing camera in the top of the windshield has failed.

Nov 12, 2025

Upon startup, LKAS, ACC, FCW and brake lights are illuminated and the corresponding systems are non-functional. This failed with less than 50k miles and the car was ~3 years old. This is making the car less safe to drive because some of the safety systems are non functional. The basic cruise control also does not work.

The front camera which controls all of the safety features went out! 1 week ago. It has been confirmed and I am now having to pay almost $2700.00 to have it fixed. I am really upset to see how many issues this year of the car has. And the fact that Honda has known about it since 2019 and did nothing to fix them. There are 318 complaints on this car and I’m guessing over half of them have to do with the front camera. It is showing 5 safety codes.

Sep 1, 2025

Dash warning lights come on for Lane keeping assist, collision mitigation, ACC, brake system, auto high beam.

The 2021 Honda Pilot would randomly flash brake, which would lock up the steering wheel, electronic warnings going off when nothing was there, and then all of the CMBS warnings came on. Dealer charged for diagnosis, and requires $2,300.00 to fix the sensor. The vehicle was never in an accident, and various ghost electronic issues would be present over the last few years before the system failed with multiple warnings.

Jul 31, 2025 Crash

The car's steering wheel got locked out and air bags came out suddenly while car is still moving on the road and driver blocked and not able to do anything and hit the parked car on the street due to car's system malfunction. Since incident happened in the housing community area with speed 20-25 miles and not majorly hit anyone but reported to and inspected by city police inspected. This was the first time this situation happed and however, had other incidents with the car auto feature malfunction, when stop on the red signal and suddenly the card shutdown with lot of beeps. This mentioned to the service center where normally go for servicing activities like oil change etc.

I have photos, but unable to up load at this time. Suddenly, 9 different consecutive warning messages with bell associated with each, appeared on the instrument panel. The barrage of these 9 messages continued until I shut the engine off. I was in a very congested parking lot when this began. The Pilot was subsequently checked for codes and battery condition. The evidence suggests the VSA Modulator. The Messages continue when powered up with or without the engine running. Lane keep assist problem. LKAS All wheel drive system problem. VSA problem. ACC Adaptive cruise control problem problem. Road departure mitigation system problem. Collision mitigation system problem. Collision mitigation system problem. TSA trailer stability assist problem. Hill start assist problem. Power steering system (EPS) problem. Plus: AWD, Brake System and steering caution lights remain on continuously. I am very glad we were not towing our travel trailer this week.

May 12, 2025

The collision mitigation braking system problem, adaptive cruise control problem, lane keeping assist problem, road departure mitigation system problem and auto high-beam problem. All these are keep showing on my dashboard.

Mar 31, 2025

It is a horrible system that makes driving with it on more unsafe. It never knows where the lanes actually are and makes adjustments that take you out of the lane all the time. It's unusable and unsafe

Mar 15, 2025

All safety/collision prevention systems related to camera have become inoperative. Vehicle will not lane keep assist, emergency brake, or notify of possible collisions. Problem occurs every time vehicle is turned on

Jan 5, 2025

The sensors stopped working when the infotainment screen went out. It goes out all the time. Honda knows of this issue but does nothing to repair.

Dec 18, 2024

Popping sounds through speakers and then infotainment screen goes black. No camera no sensors. Nothing.

Nov 25, 2024

The infotainment screen was black and not working at all so no back up camera. Also all the sensors warning you that you are getting to close to hitting something stopped working.

Nov 13, 2024

Multiple safety features are failing on this 2021 Honda Pilot. At startup, I get the following errors: Collision Mitigation System Problem, Road Departure Mitigation System Problem, Adaptive Cruise Control Problem, Lane Keeping Assist Problem. Dealership says the camera inside the vehicle needs to be replaced and it will cost $1,800. It looks like many people with similar models are encountering this problem with very young vehicles.

Oct 5, 2024

Normal driving of vehicle when suddenly several warning lights began to appear and show up every time when driving (LKAS, ACC, Mitigation, etc) despite these features working. Honda dealership claims it is due to a faulty front camera. Safety at risk because if these systems do fail, there will be no way of indicating.

The truck lights came on, with no reason, ACC and LKAS dealer wants to charge 200 just to diagnose, I keep hearing many have thir problem, honda needs to fix this problem that they know they have.

My car started stating that 6 systems were having problems. The adaptive cruise control system, automatic high beam system, blind spot information system, road departure mitigation system, collision mitigation system, and lane keep assist system. I took the car to the Honda dealer it was purchased from and was informed that the technician found that the multipurpose camera was not working and needed to be replaced. The component that failed is the multipurpose camera. My safety and the safety of others was put at risk because the following 6 safety systems stopped working. Adaptive cruise control system, automatic high beam system, blind spot information system, road departure mitigation system, collision mitigation system, and lane keep assist system. The problem has been diagnosed by the dealer. I don't know if this component has been inspected. There were no warning lights, messages, or symptoms prior to the failure. The car was just at the dealership the previous month for the annual state inspection and nothing was noted by the dealership. I was driving when suddenly the component failed and I was notified that the 6 safety systems were no longer working.

Jul 30, 2024

Upon turning on my vehicle all of the emergency warnings came on. I did a diagnostic and was shown that nothing was wrong with the vehicle but the warnings will not reset.

I was traveling with my daughters [XXX] , and [XXX] , in the back seat. It started raining heavy just as I passed a vehicle and returned to the right lane. I reduced my speed, then felt the vehicle hydroplane slightly and felt the traction control system engaged. As soon as the traction control icon displayed, I began to feel the traction slipping and noticed a slight unresponsiveness in the steering. My speed suddenly dropped 15-20 mph, without braking, or any change in pressure on the accelerator. I then tried to accelerate, but was unable to possibly because of loss of traction I noticed the traction light was flashing. The vehicle I had just passed moments before was quickly approaching at roughly 65 mph (speed limit was 70 mph) and had no warning of the issue with my vehicle decelerating, luckily they were paying attention and able to pass safely. When they passed, I pulled off the road and had these warnings on the screen: - Collision Mitigation Braking System. CMBS problem. - Lane Keeping Assist Problem. - Road Departure Mitigation System Problem. I placed the vehicle in park, shut it off, then restarted it. The error messages went away, then came back on as soon as I started driving. The traction control light remained off and the rain subsided, but the warnings remained. Dealership is supposed to inspect Wednesday 07/31/24. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ACC, LKAS, collision mitigation system problem, road departure mitigation system, and auto high beam problem warnings all appear on instrument panel. None of these systems work. Have replaced battery and problem not fixed. Warnings continue to appear each time car is turned on. Vehicle has 47783 miles on it. Codes indicate there’s a problem with the camera in the front of the car. The car is only 3 years old. Shouldn’t be having these issues. Have researched online and found many other complaints from others from various Honda models. Major safety problem that warrants a recall.

Jun 11, 2024

Front camera has failed. Dealership reports it needs to be replaced. I have crack in my windshield - now the glass company will not replace the windshield even with insurance because the camera is not working and they can’t calibrate. Having a camera on the windshield which doesn’t not work jeopardizes my family’s safety. There needs to be a plan in place to be able to replace windshield if the camera is not working and Honda should be investigated for front cameras failing. My car is just barely 3 years old. Why would a camera, which controls so many safety issues fail when a car is only 3? This should be investigated as a serious safety issue and as the rear cameras were recalled, the front should be invested too.

The warning lights beep and blink. All problems can’t be used

On 3/18/24 I started my car on a routine after school pickup trip but my notification system started blinking with different sensor problems. I took pictures of the display and tried to drive my car and saw at the time it did not affect drivability. I made an appointment with my dealer and brought it in 3/25/24. I started researching if there might be a pattern with other Honda Pilots and did find some discussion boards about 2020/2021 Honda Pilot that had a similar event—sensor problems displaying for no evident triggering event. I brought my car in for the appointment and the advisor said they would run a diagnostic as well as address 2 active recalls on my Pilot and take care of the maintenance. The diagnostic test showed that I have a faulty front multi purpose camera that must be replaced. Ny car has about $70K miles so it is outside the warranty period so I am having to pay for this repair myself. Note: the active recall that was repaired at this same visit was an issue with wiring in the rear camera. I asked the advisor if it was possible that the camera issues were related even though they were different cameras and he said at the moment there were no recalls for the multipurpose camera so he could not say. I am submitting this claim to document a possible safety concern that should be covered under a recall. Other incidents noted: when advisor asked if I had experienced any issues starting car, I did mention that last summer appx. Aug 2023 at a stop light my car went in idle mode (auto start/stop function) but when I took my foot off brake to go on green light the car did not restart. I had to get my key and push it into the ignition button to restart it. This has happened 2 since I’ve had the car. With all the recalls and these auto stop/start issues, I have experienced lower confidence & satisfaction in my Honda Pilot, but I am worried that safety may be an issue as well.

Our brakes failed coming down a steep hill. We missed hitting a car by passing in the wrong lane. We had to cross a road across two lanes which fortunately had no cars on it where we crossed. We were able to get some braking once we got on level ground. We took the car to Honda and they told us the problem was a broken break switch. It is currently at Salem Honda in Salem, Oregon awaiting parts. We were told that the repair may not be covered by warranty. We were also told that if we did not get the brake fluid replaced, the car warranty would be void. We now are being charged about $2000 to get some fluids replaced that are supposed to be replaced at 30,000 miles according to the Honda dealer.

On Friday, August 18th, 2023, I started up my 2021 Honda Pilot EX and all safety system warning lights (ACC, LKAS, CBWS, etc) came on. I called Metro Honda Montclair and a service advisor asked me to bring the car in to them as soon as possible. I asked if it was safe to drive, and he said I honestly do not know, but if you can drive it, I advise you to take the slow lane and avoid the freeway. They kept my car over the weekend, and on Monday August 21st, 2023, Dealer diagnosed the problem as a defective multi-purpose camera. These cameras are on back order until October. They said multiple codes came in in the diagnostic but they will have to start with this. I asked if I can safely drive the vehicle since the Brake System light is on, and they said "honestly we cannot tell you that it is safe, it could be something minor, or something indicating a bigger problem. The first time this happened, it turned on, and off, and the dealer couldn't duplicate it, they told me to bring it back when it happened again, and now the "problem with ACC, LKAS, CMS, Brake system, etc., these are the messages currently in the screen: "Road Departure Mitigation Problem", "Auto-High Beam problem", Collision Mitigation System Problem", "Lane keeping Assist Problem" "Adaptive Cruise Control Problem", etc., all these warning messages keep popping up and does not turn off. Honda should fix this at no charge since it impacts safety related functionality. Also, there is a water leak from under the steering wheel, water lands on my foot and in the front seats floor mats when I wash my car. [XXX] with Metro Honda Montclair said they couldn't duplicate this issue. I have pictures of all the dashboard warning messages. I showed them to the service technician. They suggested I look for alternate transportation until my car is fixed, but I do not have other vehicle and I have to transport my kids to 3 different schools, and drive to/from work daily. My car only has 20,028 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

Lane departure braking mechanism has become faulty. Over the last 2 weeks, I've had 2 incidents that could have resulted in a rear end crash, bodily injury or death, when the lane departure caused BRAKE to flash on the dashboard and the automatic system caused the Pilot to temporarily hard brake in the middle of the freeway. I reported this to POWAY Honda during my last visit, but they ignored this system problem.

May 19, 2023

When driving the collision mitigation and brakes apply , flash dash and shake wheel violently. Almost loss of vehicle control. Almost not drivable on 2 lane roads This happens multiple times during any driving. This has been ongoing since Purchase and has been reviewed by Honda dealer without correction. Only recourse was replace controls at owner cost even while under new car warranty

Jun 22, 2021

This is New Honda Pilot 2021 Trim EX-L purchase in Dec,2020. Miles 3300. It seems Honda is having software issues. Without ON of Lane Keeping Assist System (LKAS) feature is activating automatically and taking over driving or steering of the vehicle and attempt to steer the vehicle back into the center of the lane. Basically it's giving false indicator without ON of LKAS feature and due to this issue driver is becoming panic situation this will be safety issue and this will cause problems for others safety as well(Putting other at risk while driving). This is appearing from past one week onwards. Called Honda Customer Care about this issue and informed. They have taken a notes to inform R&D/Technical team and suggested to take to service to determine system failed or malfunctioned.
