1 Adaptive Cruise Control problem

Failure Date: 04/02/2026

Braking system and cameras defective. Vehicle will flash brake when nothing is in roadway. This will also cause vehicle to hard brake. When on interstate, cruise control no longer functions properly due to camera sensors reading a vehicle is in front of my vehicle when there is no other vehicle near. This causes braking system to activate and/or slow the cruise control down. This is a major safety risk for everyone involved, especially my children in the vehicle. This is a known Honda issue. This needs remedied before someone gets hurt and a lawsuit ensues. Fix the braking system and cameras!.

2 Adaptive Cruise Control problem

Failure Date: 03/01/2026

Front camera needs to be replaced. According to several Honda forums, this is a very common problem requiring the front camera to be replaced. All safety features requiring the camera no longer work.

3 Adaptive Cruise Control problem

Failure Date: 01/21/2026

Vehicle information: 2021 Honda Pilot elite component: forward collision avoidance: camera system lane departure: lane keeping assist advanced driver assistance systems (adas) failure description: the windshield-mounted forward-facing camera (lane keeping assist system / Honda sensing camera) failed without warning on my 2021 Honda Pilot elite. This camera is mounted behind the windshield and controls multiple advanced safety systems, including lane keeping assist, lane departure warning, forward collision warning, and collision mitigation braking. There were no warning lamps, dashboard messages, or other symptoms prior to the failure. The malfunction appeared randomly approximately one month ago. The issue was diagnosed and confirmed by an authorized Honda dealer service department. I was informed that the windshield-mounted camera system requires replacement and was quoted approximately $1,800 for the repair. Because this repair is extremely expensive and currently unaffordable, I have lost multiple critical safety features. The vehicle no longer has functioning lane keeping assist, lane departure warning, forward collision warning, or related Honda sensing technologies. The sudden and complete loss of these safety systems significantly reduces vehicle safety and increases the risk of unintended lane departure or reduced collision avoidance capability for myself, my passengers, and others on the road. I believe a critical safety system should not fail without warning and should not be this costly to repair, especially when its failure disables multiple core safety features. This is a known issue across multiple threads and owners and Honda should take ownership and recall this issue. The vehicle and failed component are available for inspection upon request.

4 Adaptive Cruise Control problem

Failure Date: 12/24/2025

The windshield camera has malfunctioned causing 5 different safety warnings to appear and these functions are unavailable now. It has been evaluated by a dealership and they claim that it has to be replaced at a cost of $2100. This is a pretty widespread issue in these Pilots with varying mileage. I would expect much better from a Honda product.

5 Adaptive Cruise Control problem

Failure Date: 12/12/2025

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.

6 Adaptive Cruise Control problem

Failure Date: 12/09/2025

The front camera has malfunctioned after locking down the brakes on my vehicle. Without the camera, the automatic braking system, forward collision, lane departure, adaptive cruise control, and high beam are no longer functioning. While the high beams are not as big of a deal, the safety features such as the braking system and forward collision are of more significance.

7 Adaptive Cruise Control problem

Failure Date: 12/01/2025

I am submitting this complaint to formally report a serious and widespread safety defect involving the front-facing camera system on my 2021 Honda Pilot. This defect has resulted in multiple safety system failures and has placed myself, my passengers, and other motorists at unacceptable risk. The front camera on my vehicle does not function as designed, which has caused the complete loss or repeated failure of critical safety features, including adaptive cruise control, lane keeping assist, lane departure mitigation, collision mitigation braking, and other forward-facing driver assistance and alert systems. These systems are not optional or convenience features. They are advertised and sold as essential safety technology intended to reduce accidents, mitigate driver error, and protect human life. Their failure substantially impairs the vehicle’s safety performance and creates a foreseeable risk of serious accidents, injuries, or fatalities, particularly during highway driving or emergency situations. When I sought assistance from the dealership, I was informed that Honda would not cover the repair because the vehicle exceeded a mileage threshold. This rationale is unreasonable and misleading. A front-facing camera is not a wear-and-tear component and has no logical connection to mileage accumulation. It is an electronic safety system whose premature failure suggests a defect in design, materials, or manufacturing. I then contacted Honda directly, and the manufacturer again refused to provide assistance, citing mileage alone while failing to address the safety implications or defect characteristics. This refusal appears to be an attempt to avoid responsibility for a known safety-related failure rather than a legitimate warranty determination. Further research reveals that this issue is not isolated. Numerous Honda owners have experienced identical front camera failures resulting in the same loss of safety systems. The consistency, frequency, and similarity of th.

8 Adaptive Cruise Control problem

Failure Date: 11/19/2025

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.

9 Adaptive Cruise Control problem

Failure Date: 09/30/2025

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.

10 Adaptive Cruise Control problem

Failure Date: 09/03/2025

I have two issues. First issue is the car will hit an intermediately not start once shut off and will take a few times of making sure the car is completely shut off opening your doors letting it power down before being able to restart. The next issue is the forward collision notification will randomly beep at every car that goes by specifically white cars. And also the adaptive cruise control brakes a little bit harder than expected.

11 Adaptive Cruise Control problem

Failure Date: 08/22/2025

The following warning lights: adaptive cruise control problem, lane keeping assist, collision mitigation system, road departure mitigation problem, auto high beam problem. Honda estimates over $2000 to repair? from what I understand there are many other Honda's with these issues! with these items not functioning, it defeats many of the safety features we bought the car for. Exact date of when it began was last summer.

12 Adaptive Cruise Control problem

Failure Date: 07/15/2025

All I did was simply change my battery. Up until this point the car had run perfect and no issues or warnings. Now after placing the correct agm battery the dash has lit up like christmas. I am getting acc, lkas, auto head light, forward collision and brake system warning lights. I was informed that this is a very costly repair, a camera needs to be replaced and recalibrated, $2000 estimate. This should be a recall based on the other numerous complaints I'm seeing. I reached out to Honda with no response as of yet.

13 Adaptive Cruise Control problem

Failure Date: 07/10/2025

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.

Failure Date: 05/24/2025

Recently , I stated seeing cmbc failure in my 2021 Honda Pilot 2wd. My car has 41500 miles in it. I took car to dealer ship and dealer ship says they are no recalls I need to change my camera. I am not understanding it's like brand new car and not driven many miles. I research on google and there are so many Pilot owners having same problems. Can this be recall?.

16 Adaptive Cruise Control problem

Failure Date: 04/16/2025

This seems to be an on going problem for many Honda owners according to the forums. My adaptive cruise control, lane keeping assistant, collision mitigation, road departure mitigation, and auto high beams have all gone out after going to the car wash. I have cleaned the windshield but I find it crazy that this is a common problem and there is no recall.

17 Adaptive Cruise Control problem

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.

19 Adaptive Cruise Control problem

Failure Date: 02/19/2025

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 it is an infotainment system problem and it will cost about $1,200.

20 Adaptive Cruise Control problem

Failure Date: 01/06/2025

I purchased my vehicle approximately 8 months ago, and recently all of the warning lights on my dashboard began coming on randomly while driving. I immediately brought the vehicle back to the dealership where I purchased it. At that visit, I was told the cause was unknown and that it might possibly be related to the battery. Unsatisfied with that explanation, I took the car to a second authorized dealership for another opinion. After inspection, I was advised that there was nothing wrong with the battery and no clear cause was identified for the warning lights. Despite taking the car to two dealerships, I have received no resolution or effective support. The issue remains ongoing, and I am now left uncertain about the reliability of my vehicle. Warning lights are designed to alert drivers to serious problems, and when they come on without explanation, it creates a very real safety concern. I do not know if my car is safe to drive. My concern is heightened by the fact that I have since learned this vehicle model has been subject to a recall in the past for the same issue. This raises the possibility that my car may be experiencing a known defect that was not properly resolved. As a consumer and driver, I should not be left to guess about the safety of my vehicle, especially when a documented recall exists. I am formally requesting immediate assistance: a complete inspection by a qualified technician, confirmation of whether my car is covered by any recall, and repair of the defect at no cost if it is recall-related. I also request written documentation of findings and assurance that my vehicle is safe to operate. At this point, I feel I have not been provided with adequate support or resolution. I am extremely concerned for my safety and believe this matter requires urgent attention.

21 Adaptive Cruise Control problem

Failure Date: 12/18/2024

Brake system light on, adaptive cruise control problem and road departure mitigation system problem error messages. Brakes light turn on randomly, even when car is off. This intermittently causes issues with acceleration pedal not responding while driving as well as being able to start vehicle without depressing brake pedal which is a major danger if kids are inside and pushes the button. Unable to accelerate when needed also causes problem that can lead to a crash.

22 Adaptive Cruise Control problem

Failure Date: 11/01/2024

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.

23 Adaptive Cruise Control problem

Failure Date: 10/26/2024

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.

24 Adaptive Cruise Control problem

Failure Date: 09/27/2024

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.

25 Adaptive Cruise Control problem

Failure Date: 07/30/2024

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.

26 Adaptive Cruise Control problem

Failure Date: 07/02/2024

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.

27 Adaptive Cruise Control problem

Failure Date: 05/28/2024

Vsa modulator failed at approximately 69,000 miles. Safety features were inoperable putting my family at risk. Dash said to contact a dealership and to not drive the vehicle. The dealer informed us that the car was safe to drive as long as it wasn't making any funny noises. I paid the dealer to replace the vsa modulator per their diagnosis but then upon the car being returned to my possession, I was informed all the alarms are present on the car again. The dealer is instructing that I now need to replace the forward camera / radar sensor.

28 Adaptive Cruise Control problem

Failure Date: 04/22/2024

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.

29 Adaptive Cruise Control problem

Failure Date: 04/15/2024

Frequently, my 2021 Honda will apply the brakes without warning or very abruptly. While using the adaptive cruise control, the car will brake suddenly when there is not a car anywhere near me. Also, when driving on two lane roads, the car slams on the brakes when there is not a car in front of me.

30 Adaptive Cruise Control problem

Failure Date: 04/08/2024

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

31 Adaptive Cruise Control problem

Failure Date: 10/18/2023

1. Driving on a 2 lane highway, at about 65 mph, using cruise control. No vehicles ahead on me in my lane. Truck in oncoming lane caused dash to display brake warning. Brake came on momentarily, wheel was in staight forward position. 2. Have had similar problems with cruise. Driving at 45 mph in left lane, cruise on, car ahead of me moves to left turn lane, dash brake light comes on and brakes momentarily go on. For this took into Honda dealer, unable to replicate by their service tech.
