Adaptive Cruise Control Problems of Honda Pilot - part 1

My 2021 Honda Pilot displayed a u3000 diagnostic trouble code, indicating an internal electronic failure of the front-facing multipurpose camera that operates the vehicle's Honda sensing safety systems (collision mitigation braking system, lane keeping assist system, road departure mitigation, and adaptive cruise control). As a result, these safety systems became inoperative. I took the vehicle to an authorized Honda dealer, who confirmed the u3000 code and quoted approximately $2,000 to replace the camera unit. I have since learned this is a widely reported failure across multiple Honda and Acura models (pilot, odyssey, cr-v, accord, civic, hr-v, clarity, rdx, mdx) and is the subject of a proposed class action lawsuit alleging Honda knew of the defect and failed to disclose it or issue a recall. I am filing this report to document the failure and its safety impact.

My 2022 Honda Pilot black edition (VIN 5fnyf6h07nb042859, 62,900 miles) has multiple intermittent safety?critical failures involving the transmission, acceleration, adaptive cruise control, and hvac blower. These issues occur without warning and without diagnostic trouble codes. Transmission/acceleration failure: most recent incident was 7/30/26 on highway 71 during heavy traffic. The vehicle twice experienced rapid deceleration with no ability to reach a safety stop. Rpm dropped below 1000, then spiked to 6,000–8,000 while the vehicle continued to lose speed. Acceleration returned only after several seconds. This also occurs during highway merging and uphill acceleration. Additionally, when disengaging cruise control and immediately pressing the accelerator, the vehicle loses speed, rpm drops abnormally low, then spikes before power returns. Adaptive cruise control/Honda sensing failure: on 7/30/26, the vehicle rapidly decelerated when a semi?truck was beside me, despite no vehicle ahead. The week prior, while driving several states away, setting cruise at 70 mph caused sudden deceleration and cruise resetting itself to ~54 mph. These events resemble phantom braking and radar mis?targeting. Hvac blower failure: during a long multi?state trip the week prior, the ac blower (speed 3–4) intermittently stopped blowing for several seconds, then resumed at the same speed with no change to the display. These failures affect powertrain, forward collision avoidance, vehicle speed control, electrical systems, and cabin equipment. The dealership (roush Honda, westerville OH) cannot replicate the issues and reports no stored codes. These defects pose significant safety risks.

A little after hitting 114000 miles, all the lights came on the dashboard: brake system, acc, lkas, automatic high beams, collision mitigation system. We had the battery checked and it is not the battery. All the camera sensors are clean… many other Honda Pilot owners have expressed this same problem online.

When I started my 2019 Honda Pilot touring car on 7/13/26 morning, where the screen where the speed usually shows showed amber colored warnings for Honda sensing features: acc, lkas, cmbs, road departure mitigation system, auto high beam. Lkas, cmbs and brake system amber icons are on. Infotainment display shows acc and cmbs has a problem. I tried cleaning the windshield and sensors in the front but same warnings still continued to show at next start up and drive. Last few days I started it still pops up so I took it to independent shop yesterday 7/15/26. They pulled a u-code for multipurpose camera, tried to clean the sensors but warnings would still show so it's a hard code now. I had them document it for me. These are safety features that came with the car, should they be failing this early on? I have not done anything to there, haven't been in any accidents involving that area and haven't had windshield replaced either. They weren't able to fix it as they don't have the calibration equipment so said we'd need to send to Honda dealer.

Front camera failed so none of the cars safety features are working and every warning light is on on the dash. Part is unavailable in USA.

Driving on the road and heard static noise from the infotainment system after an update. I pressed the collision mitigation braking system button and the dashboard had multiple warnings and disabling the entire advanced driver assistance systems (adas). The drive light starting blinking and a message appreaed to get to a Honda dealer. The Honda dealer inspected the front camera in the top of the windshield and said it needed to be replaced.

Additional comments for complaint #11750912:I am uploading photographic evidence of severe material delamination on my vehicle's front radar emblem shield (part #71125-tg7-a51) [71125-tg7-a51]. This manufacturing defect caused a critical safety failure: my vehicle recently executed a sudden, violent phantom braking event on the highway with absolutely no prior warning lights or error codes on the dashboard. The peeling layers and air bubbles on the emblem physically refracted the radar signals, creating a false target that locked the brakes and nearly caused a severe rear-end collision. While I was driving alone during this specific incident, this car is my primary family vehicle used daily to transport my wife and my three young children. I am now genuinely terrified to drive my family in this vehicle and must manually turn off the cmbs system every time I start the car to protect them. American Honda corporate (case #16495852) has formally refused to address this active braking hazard, deflecting the issue by focusing only on unrelated radio glitches. I request a federal safety investigation into Honda’s radar emblem material degradation, as it directly compromises collision-mitigation systems without triggering automated dashboard fault alerts, putting families and young children at immediate risk.

I am filing this complaint because my 2019 Honda Pilot has developed a serious safety-related defect. When I started the vehicle, multiple warning lights remain on, including the lkas, acc, cmbs, and brake system warnings. I haven't had it inspected by the dealer yet, as the closest dealer is 25 miles away down a curvy mountain road. I expect that it will be determined that the front-facing camera has failed. Because this camera supports several driver-assistance and warning systems, the failure has made those systems unreliable and prevents the vehicle from accurately alerting me to other potential problems. This creates a significant safety concern because, if another malfunction occurs, I may not be able to distinguish it from the existing warnings. The warning lights remain active unless the camera is replaced at an estimated cost of $2,600. I do not believe owners should be responsible for such an expensive repair when the failure affects critical safety and warning functions. This issue appears to be recurring among 2019 Honda Pilots, with similar complaints reported by other owners online and in social media forums. I respectfully request that Honda investigate this defect and provide an appropriate remedy, including repair assistance or coverage for the failed camera system.

At least 4 times since we bought this vehicle in 2025, it has suddenly braked very hard, and very suddenly at highway speeds. This has always happened when using the car's adaptive cruise control, and when I am passing a large vehicle (semi truck, pickup with large camper, etc). This has happened at relatively high highway speeds (85 mph) when vehicles are behind me in the passing lane. The problem has never been reproduced or confirmed by the dealer, although I have complained about it twice. The first time, they said they lowered the sensitivity of the crash detection. The second time they showed me how to manually turn off adaptive cruise control manually. There was no prior warning when this happened, no lights or messages. This has happened about 4 times since fall of 2025. The date below is approximately the last time, and the last location that this happened.

While operating my 2019 Honda Pilot, the vehicle experienced a sudden and complete failure of its advanced driver safety systems. Without warning, a cascade of simultaneous error messages illuminated on the dashboard, completely disabling the collision mitigation braking system (cmbs), road departure mitigation, adaptive cruise control, and lane keeping assist networks. This defect renders critical safety features completely inoperable and causes severe driver distraction due to persistent dashboard warnings flashing on the loop. This failure occurred when turning on the car. The sudden loss of safety systems while traveling at highway speeds poses an unreasonable risk of a crash, as the vehicle can no longer utilize automatic emergency braking or lane assistance features. The vehicle currently has about 88000 miles. The dealership has indicated the issue stems from a failure of the front-facing windshield camera sensor, matching the systematic defect patterns alleged in active federal class-action litigation against Honda. I am requesting that the NHTSA formally investigate this widespread camera component failure to mandate a safety recall.

The vehicle suddenly made audible and visual warnings stating critical error. All of the safety features handled by the forward-facing multipurpose camera stopped working. Honda stated the camera has failed (common issue based on research), and is a costly repair. Vehicle less than 6 years old, all maintenance completed timely by Honda, mileage 81k.

My Honda has recently began displaying adas failure where none of the features work including cruise control. I took to a mechanic and they displayed code u3000. This seems to be a common issue that Honda is not addressing. The fee to repair is over $1500 and the car is less than 5 years old. This is a safety issue.

The car brakes for cars parked on the side of the road when using cruise control if the road curves. Today, it braked on train tracks while there was nothing impeding our path for at least a mile.

2021 Honda Pilot with 9,800 miles. Failed vsa modulator directly related to the braking system. Warning lights: vehicle stability assist, trailer stability assist, collision mitigation system, adaptive cruise control problem. Problem confirmed by pensacola Honda service center and awaiting repair assistance from american Honda as they refuse to offer goodwill credit for repair due to being out of warranty, despite extremely low mileage and excellent condition of vehicle.

While driving, there was a loud noise came from the engine. I immediately pulled over onto the shoulder as I was unable to continue driving. Every time I accelerated, the car with jerk forward and posed an extreme danger for both the the passengers and others on the road. There were numerous error messages appearing on my dashboard, and the loud noise persisted. The local dealer found that there was an issue with the engine and needs engine replacement. I contacted manufacturer Honda and they not willing to help me as my 6. 3 year vehicle is out of 5 year warranty.

There are several lights that come on and say there is a problem. Upon looking online for information on how to fix it there are numerous people with the same issue and there should be a recall.

Warning lights for adaptive cruise control, lane keeping assist, collision mitigation, road departure, and auto high beam all came on simultaneously. From reading several Pilot forums, this seems to be very widespread and dealerships want anywhere between 1500 and 1900 to replace and calibrate the camera system which controls these functions. If it’s widespread, the vehicles should be recalled.

My 2019 Honda Pilot had warnings( see pics). I took into Honda for inspection. We were told it was a radar (sensor). After doing some research online, this is a common issue with Honda vehicles. The cost is $2000 to fix. Why is this not a recall issue???.

Monocular windshield camera premature part failure. 36160-tg8-a72-m1. Premature failure of the part causes all included safety systems to be disabled, and also negatively impacts standard cruise control. The part was sent for repair and the lens was thermally degraded as well as processor board non functional. There was no thermal paste installed on the processor. When the camera fails, an improper transmission failure warning light also appears on the dashboard, which prevents smog testing from being completed despite the camera system not impacting emissions at all.

My dash is lit up like a christmas tree. The cmbs has a serious issue, every safety feature has been disabled. Please refer to the he provided picture.

2025 Honda Pilot elite. Honda sensing / adaptive cruise control consistently fails to recognize motorcycles traveling directly ahead (approx. 66% failure rate). The system radar/camera bypasses the motorcycle and locks onto the larger passenger vehicle further ahead, creating an imminent rear-end collision risk with the motorcycle.

The fuel injectors have been diagnosed by my local dealership with all the appropriate codes referencing the following extended warranty bulletin issued by Honda for the repair of all 6 fuel injectors and related parts to be installed free of charge. Honda issued a warranty extension for the 2019 Honda Pilot fuel injectors under service bulletin 20-100. ?warranty coverage details ?expiration point: the warranty is extended to 10 years from the original date of purchase or 150,000 miles, whichever comes first. ?condition: the vehicle must display a malfunction indicator light (check engine light) with specific stored fuel-system error codes (such as p0300 through p0306, p0420, p0430, p219a, or p219b). ?how to get coverage or file a claim ?1.

I have a 2019 Honda Pilot touring with an intermittent fault. At apparently random intervals, I'll 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 if I drive the car a couple of miles, there's a 50-50 chance I'll get them the next time the car starts. It's not throwing any fault codes. Had the oil changed, battery checked, cleaned the "h" sign to make sure it wasnt anything dirty on the radar.

Windshield cracked majorly after being hit by a small rock on the highway. Even after having it replaced and the camera recalibrated, 7 safety warnings of the adas come on. Reportedly, the frontcamera has failed, which is concerning in a car that has less than 50k and is just about 4yrs old. I believe this is a larger issue, the windshield truly should not have broken that easily and the camera failing so soon is problematic. It is also a very expensive fix.

When starting vehicle after leaving the grocery store, there were multiple fault messages displayed on the dash cluster. They were showing five fault areas, the adaptive cruise control, forward collision warning, lane departure warning, lane keeping assistance and parking collision warning. When arriving at the Honda dealer service department I was advised that this is a common issue and would most likely be a front camera failure. After the Honda service department diagnosed the issue they confirmed it was a camera failure. I contacted american Honda asking for goodwill assistance and after giving all of my information, I was sent an email to reply to with the same information. Two days later I received a call and had to go over the same information a third time. I was advised this process would be 2-3 days. Three days later I receive a call and was requested to give the same information a fourth time and the told it would be 3-5 days from then to evaluate and I would receive a call. Four days later I called american Honda for status and was offered a partial goodwill assistance that I would be need to pay $955 for the repair instead of $2200+ which was originally quoted. From working for Acura for 17 years it is obvious that american Honda assisted minimally as the warranty rate is around the same cost. They made the dealer take the cut in pay and endured minimal cost to american Honda and a major cut ended by the dealer. Being this is a common issue with a $2000+ cost, there should be more consideration allowed for this failure.

I was driving with my cruise control on, at the speed around 50 mph, thank goodness no other cars were around us, all of a sudden my car slammed on the brakes, a warning flashed but I happened so fast I wasn’t able to see what it said.

The vehicle’s driver?assist and collision?avoidance systems began failing simultaneously. Multiple warnings appear on the dashboard every time the vehicle is started, and the cruise control system has stopped functioning entirely. Adaptive cruise control cannot be disabled, preventing the use of standard cruise control. Collision mitigation system problem adaptive cruise control problem (acc) lane keeping assist problem (lkas) road departure mitigation system problem auto high-beam problem the failure of one component impacts multiple vehicle features, the ability to maintain safe following distance, avoid collisions, stay within lane boundaries, and properly manage headlights. The loss of cruise control functionality also affects long?distance driving safety and consistency. These systems are designed to prevent accidents; their simultaneous failure represents a significant safety hazard. Dealer inspection indicates repairs costing thousands of dollars, often involving replacement of sensors, radar units, or wiring harnesses. No recall or service bulletin has been provided to address this widespread issue. Many Honda owners have reported identical failures on online forums and owner groups. The pattern suggests a systemic defect affecting Honda’s driver?assist safety systems across multiple models and years. I am requesting that NHTSA investigate this issue as a potential safety defect affecting Honda vehicles. The failure of multiple collision?avoidance and lane?keeping systems at once poses a serious risk to drivers, passengers, and others on the road.

The front sensor camera has damaged, causing security issues.

About a month ago, I started my Pilot and the dash lit up. The adaptive cruise control, emergency braking, lane keeping assist, lane departure, forward collision warnings all flashed on the dash- no previous warnings. Subsequently, the cruise control will not work at all. I had the system scanned by a Honda certified mechanic and it showed and internal cameral failure. This is a known issue across many Hondas and is a very costly repair at close to $2000.

The contact owns a 2025 Honda Pilot. While driving at an undisclosed speed, the vehicle suddenly decelerated, and the steering wheel started jerking. The messages eps failure, lane keep assist, and adaptive cruise control failure were displayed. The contact safely pulled over to the side of the road. The vehicle was towed to a dealer, but was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 3,200.

These systems have stopped working due to a faulty lkas camera that is mounted at the windshield.

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!.

I have several lights on my dash after getting a part changed. Road departure mitigation, adaptive cruise control problem, collision mitigation system problem, auto high beam problem.

I leased this vehicle in oct2019 and then brought this vehicle and till date did 44710 miles and on 2/25 we had multiple warnings on the dashboard regarding lane assist failure, adaptive cruise control, break system failure, forward collision failure and many more warnings, we took it to Honda dealer to investigate and they said that he don’t monocular camera has to be replaced with a estimate cost of $2395, when searched online there are many customers of the 2019 model facing the same problem and are subjected to such high repair cost. I believe that this is a faulty part from Honda and needs to be recalled and fixed as this impacts critical safety functions.

Acc and road departure mitigation system would become disabled for no apparent reason. A message would display on the instrument panel that there is a problem, to see your dealer. Also, a collision mitigation braking system problem would display on the instrument panel with a brake system warning light. A display on the instrument panel would show an area to clean (Honda emblem on front grill). I tried to clean this area several times to no avail. The weather was clear and warm when this occurred. The system has returned to normal on its own.
