Adaptive Cruise Control Problems of Honda Pilot - part 1

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 NHTSA 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 NHTSA 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.

Some drive assist systems cannot operate: clean area shown. This message keeps appearing without any weather factors or anything to cause it. Happens nearly daily while using adaptive cruise. Then the next day without doing anything (like cleaning area) it starts working.

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.

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.

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.

After driving my car from the dealer after purchase all the safety features have warning lights on the dash. Break system error ,electric power steering problem ,road departure mitigation problem, collision mitigation problem, lane keep assist problem, adaptive cruise control problem, tsa problem, hill start assist problem, vsa problem, abs problem, electric parking brake problem. Its seems like all of the safety features are not working. I took the car to the dealer and said it was just a battery issue, they went ahead and replace the battery but it was still the same, all the error message came out soon after driving from the dealer service department. After that they said they will replace the speed wheel sensor. I got my car back hopefully that resolved the issues. This cars should not pass qc, this problem happened right after driving the vehicle of the dealer lot after purchase.

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.

My cruise control stopped working and all my lane assist stopped working. My front camera stopped working. I went to the Honda dealership, and it was going to be over $2000 to replace. The car is only 6 years old, it has had no accidents or problems. I’m incredibly upset that this already is a problem, and because I didn’t buy an extended warranty it’s on me to fix.

So my front sensing camera failed after 125,000 miles , Honda sensing features disabled and dealer in elk grove, CA zip code 95624 quoted me 2,215 plus tax and that includes diagnostics. It showed 5-6 errors on my dashboard which have disturbed my focus on driving. Advisor said there’s no recall on this issue or warranty at all except if you bought an extended warranty. This is not fair as this is an electronic automated design, this should have a warranty. This will pose danger to customers who owns this vehicle.

Front camera stopped working all of a sudden and didn't help with lane assistance.

All the sudden the lights in dash went off reading lane keep assist failure, adaptive cruise control failure, and automatic brake system failure. Nothing was working, lights stayed on, took to auto body shop, they said I need a whole new front windshield camera and for it be recalibrated, that will cost more than $2000. Honda is saying this isn’t under warranty or recall but it seems like it keeps happening to many Hondas when you look up the same problem so it should be a recall.

The automatic braking will brake unintentionally while driving on the highway or street. The vehicle will brake suddenly without warning. It will do this in all kind of conditions. It happens when there are no vehicles around as well. This is very scary and it has almost gotten us into accidents.

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.

My vehicle multipurpose camera unit failed. The entire advanced driver assistance system shut down and stopped working. This error randomly appeared. My vehicle has 48,000 miles on it. I received error codes for each of the components that they were not working. This meant no adaptive cruise control, no automatic emergency braking, no blind spot warning, no forward collision warning, no lane departure warning, no lane keeping assistance, no parking collision warning, no rear cross traffic warning. My safety was put at risk as the components that provide safety warnings were not operative. I took the car to my Honda service shop and they provided the following diagnostic: [other]: verify customer concern that theirs multiple lights on on the vehicle, then check for codes notice theirs code for u3000-49 multipurpose camera unit/ millimeter wave radar internal electric failure. Then disconnect one of the connectors for sensor to single one out to see if when clear the code to see if stays on or not, after clearing the code lights still came on and code pop on. Recommend start first replacing with a new multi purpose camera, and retest. I paid for the repair as it needs fixed for safety purposes. The cost was $1,950. 00. Honda should be responsible for covering this as it is some type of camera malfunction and the vehicle is only 3 years old.

At random intervals, I get the following faults on start: adaptive cruise control problem lane keeping assist problem collision mitigation system problem road departure mitigation system problem auto high-beam problem.

There was an internal failure of the multi-purpose camera located behind the windshield rear-view mirror. It was inspected by russ darrow Honda and the failure code diagnosed. The camera needed to be replaced. Service included a video from the dealer and the defective camera was so hot he could barely hold it while wearing gloves. This caused the lane-keeping assist, adaptive cruise control, auto high beam, collision mitigation and road departure mitigation systems to fail, and the dummy lights on the dash to warn of the system failures. There was no accident or injury resulting yet, but none of the advanced safety features were operable. We have since learned that this camera is a common failure in Honda vehicles, and we feel there needs to be a recall. This critical and expensive safety feature should not be failing this frequently, or in vehicles this new.

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.

My 2019 Honda Pilot [xxx] with 68k miles) recently began to have startup errors and issues with the automated driver safety systems. The five errors that are routinely displayed on the dash info display are: collision mitigation system problem road departure mitigation system problem adaptive cruise control problem lane keeping assist problem brake system information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The multi function camera is causing multiple system failures within the safety systems associated with the camera as well as additional issues with transmission. Honda suggests throwing parts at it until repaired. Many owners on forums report same issue across different model years and trim levels. Known issue not being resolved by manufacturer.

The lkas camera stopped working and it won’t allow any of the connected systems to operate including acc, emergency brake assist, cruise control, etc.

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.

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.

The front camera driving assist malfunctioned, causing all driving safety mitigation to be stopped. This is not an issue due to the driver, it is an issue with the camera either malfunctioning from heat from sun exposure or being faulty due to manufacturing issues. I reported to auto national Honda valencia & they said it would cost approximately $2200 to fix. Dash light did come on and are continuing to go on until the faulty camera is replaced.

My 2019 Honda Pilot has 47817 miles on it. Purchased new from dealership. Been garaged entire life other than normal routine driving. Recently had adas warning lights. Reported the problem to Honda hq in torrance California. They issued a claim number. I took it to Honda dealer where it was diagnosed with error code u3000-49. They quoted me approx $2600 to replace and calibrate the new multi purpose camera. When reviewing the internet for others with similar problem I noticed this was a safety issue that was far too common among relatively new Honda vehicles. I received a discount from Honda and had the service. The discount was only given when I complained about this issue as well as my 2013 Honda Pilot I purchased brand new which the clear coat paint started to come off the roof and hond of the vehicle about a month after I purchased my 2019 Honda. When reporting the problem with the 2013 Pilot losing the clear coat back in 2019 Honda told me it was too late for them to do anything. Honda should have recalled vehicles with peeling clear coat as well as the defective adas system.

After starting my vehicle and leaving the office, several different warning messages began flashing on the dash abs, lane departure mitigation, power sterring, towing. I pulled over and turned the vehicle off. When I attempted to restart the vehicle, the brake pedal was hard and felt stuck. The car did not start. When roadside assistance came, they tested the battery, and it was fine. The car was towed to a Honda dealer and the technician informed me the brake pedal position switch failed. He said that it would have caused all the different warning messages to appear. This was the second time this occurred, where the different warning messages lit up, but that time the car restarted. When I took it to the dealer that time, they could not determine the issue, and no repairs were done. I am concerned because I have seen that these vehicles have issues with this and it is very dangerous and unsafe when it comes to issues with the brakes.

No incident. Turned my car on and the acc, lkas, collision mitigation and brake system lights all are amber.

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.

All the associated warnings are on dash, diagnosed at local Honda dealership with code u 3006-16. Advised multi camera failure and requested $1600 to repair. Immediate after I am now getting a transmission warning problem on dash.

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?.

While driving with speed control on the vehicle will show warning light in dash and say something is blocking front camera sensor. Causing mirrors to tint automatically xm radio to stop bluetooth problems and no crude control. Nothing blocking camera have to stop and restart vehicle. Throttle problems intermittent not smooth. To much throttle causing it to shift hard at start downshifting is hard and can also do this in reverse. Have had this at a dealer once and bring back again. They adjusted the throttle body. Seemed to do nothing.

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.

During normal operation of the vehicle, the dashboard information display on the gauge cluster lit up displaying the following error messages: adaptive cruise control problem, collision mitigation system problem, lane keeping assist problem, auto high-beam problem, road departure mitigation system problem. Additionally there is a fixed "dash light" that is showing "brake system" illuminated in amber color. After research I have found that Honda issued a TSB for other vehicles with their sensing system for the same issue and referenced the high-mounted mono camera on the windshield. This issue extends to the 2019 Pilot elite that I own and significantly reduces the safety features of this vehicle.
