While driving the vehicle under normal conditions, multiple advanced driver assistance and safety systems suddenly became unavailable without warning. The systems affected include automatic emergency braking, forward collision warning, lane keeping assistance, and related safety features that rely on the forward-facing camera. The failures occurred at the same time and were indicated by warning messages displayed on the instrument panel. The vehicle was inspected by an authorized dealer, who confirmed a diagnostic trouble code indicating an internal electronic failure of the forward multipurpose camera. The failed component is installed behind the windshield and is available for inspection upon request. The dealer stated that no accident, physical damage, misuse, or external cause was identified. After the camera failure was identified, the vehicle also briefly displayed a transmission system warning message that later cleared on its own. In addition, the center display screen has shown unstable behavior while driving, including unexpected resets and flashing back to the navigation screen. The sudden loss of collision mitigation, lane assistance, and warning systems reduces the vehicle’s ability to assist in avoiding crashes, particularly in emergency situations, and increases safety risk to the driver, passengers, and others on the road.

While driving on highway, multiple warnings displayed at the same time as adaptive cruise control stopped, lane keep assistance stopped and collision mitigation system stopped abruptly without warning. Independent service check confirmed the problem. No inspection performed. Vehicle has never been in a collision during ownership.

Front camera is bad or faulty, triggering all adaptive cruise control, lane keep assist, auto high beam etc errors on dashboard, rendering the car not able to start or die in the middle of the road/traffic when the engine goes into idle mode while stopping at red lights. My odessey has over 111k miles when these issues start showing, but lots of people report experiencing same issue with even with their newer odessey. It doesn’t feel right why Honda installed cheap cameras especially when it plays a crucial role involves safety of the car and the driver.

System failure for all of the safety-related assistants. Works intermittently, but mostly indicates failure.

Getting error code for safety sinsing. Lane keep assist, collision mitigation system and now transmission system. Forward facing camera is cause of issue.

The front windshield camera completely failed. No longer have emergency braking. Honda said known problem and want to charge $2000 to fix.

The front monocular camera assembly (Honda part number 36160-thr-a81) on my 2019 Honda Odyssey elite failed and is available for inspection upon request. When the failure occurs, the vehicle displays multiple warning messages including “collision mitigation system problem,” “adaptive cruise control problem,” “lane keeping assist problem,” “road departure mitigation system problem,” and “auto high beam problem. ” as a result, several driver-assist safety systems are disabled, including automatic emergency braking, adaptive cruise control, lane keeping assist, and road departure mitigation, which reduces the vehicle’s active safety features and increases the risk of a collision. The warnings appear simultaneously on the dashboard while driving and remain active until the vehicle is restarted. The condition has been reproduced multiple times and has been confirmed during diagnostic inspection by a service technician. The camera failures are very common and are a design defect. The design was changed in later years but there was not a recall for the 2019 models. This is a very expensive fix and should be covered by a recall.

The camera module failed in our van and gave us a u3000-49 code which caused the vehicle to lose adaptive cruise control (acc), lane keeping assist system (lkas), collision mitigation braking system (cmbs), and road departure mitigation (rdm) functions on the vehicle with a cost to fix from Honda of $ 2,475. 56.

The car has started giving warnings every time I turn it on (as of 6 months ago): adaptive cruise control problem, collision mitigation system problem, auto high beam problem, lane keeping assist problem. It seems there must be a fault in the windshield camera that renders all these safety features useless. The repair shop stated that windshield camera isn’t working and is a $2k or more to repair. I am now driving a minivan that doesn’t have many important safety features and this is very dangerous.

System is starting to fail by alerting me to clean windshield. Windshield and camera have been cleaned, still getting multiple warnings that system is shutting off safety features during my commutes.

All Honda sensing / adas safety warnings appear at the same time while driving or shortly after starting the vehicle. When this happens, all driver assistance systems are disabled, including: •adaptive cruise control (acc) •lane keeping assist (lkas) •collision mitigation braking system (cmbs) •road departure mitigation •automatic high beam when the failure occurs, the vehicle displays multiple safety system warnings and the entire driver assistance system shuts down, leaving the vehicle without any adas safety features.

Multiple system problems constantly on my dashboard. Has brand new spark plugs and battery and problem is still there.

We turned the car on and got an acc, lkas, fcs, ahl errors due to the front sensor and the camera failing. This is an issue that many Honda owners are dealing with. The issue will not allow you to use cruise control and will disable 90% of the safety features we bought this vehicle for. The car drives fine but the safety of those in the car is affected by this error and needs to be recalled due to the number of complaints of this issue. There were no errors or warning signs prior to this happening.

I own a 2019 Honda Odyssey elite with 39,000 miles on it. In January 2026, suddenly I had multiple warning lights on in my minivan related to an adas system failure. I replaced the car battery and later determined that the adas camera had failed in the car. In reading online, this is a very common issue with Hondas as the cameras are known to overheat and require replacement. Warning lights: brake system malfunction, adaptive cruise control problem, collision mitigation system problem, lane keeping assist problem, road departure mitigation system problem, auto high beam problem before I was able to get it repaired, the van turned off suddenly in traffic twice while my wife was driving the car while also one of my children was inside, creating an unsafe condition that could have created an accident. Luckily my wife was able to get the car safely moved out of traffic and we stopped driving the car at that point. I wound up replacing the camera and and needing to get it recalibrated so that the car could be drivable. This resulted in the van not being operable for nearly a month. For a car that had 39,000 miles on it, this really should be something under a longer warranty as it could have created an unsafe driving condition for my family. Total cost to repair = $1634. 22.

Front camera is known to go out on these vans causing acc, lkas, collision mitigation, road departure mitigation system, auto high beam, transmission problems and more.

Warning lights stay on for: adaptive cruise control problem (acc); auto high-beam problem (a); road departure mitigation system problem; collision mitigation system problem; lane keeping assist problem (lkas); brake system lights. Lights will not clear. Dealership diagnosed for replacing monocular camera on front windshield/mirror. Gary smith Honda replacement cost $2364 on 20jan2026.

The front camera that is responsible for adas suddenly died and it is very vurnerable to heat. The unit gets very hot and it gets hot quickly. The lifespan of the unit is very short and the dealer is asking for $2000 to replace it like they have seen this pretty often.

Our front camera on windshield failed at 96k miles, causing all lights to come on the dash. This resulted in all safety features failed and even basic cruise control doesnt work. Lots of Honda owners have same issues and the result is that it is a failed front camera which could cost around 2k to replace. There is no other way around it. It is found out that the camera could over heat leading to failure. This issue should be a recall because it is a safety concern. Could you please look into it? thank you for your time.

The camera for these sensors has gone out and it appears to be an extremely common issue. It makes all safety features un-usable.

While driving down the road way the collision mitigation warning failure flashed and then pulled the steering wheel pulled me off the roadway and nearly caused me to crash.

After researching I find it to be a sensor in the windshield is a common problem.

All of my adas systems were disabled due to a water leak. The repair required the dealership to hire a "leak doctor" and then replace a module in the rear tailgate. My vehicle showed an alert on the dash that each of the adas features were disabled, auto high beams were disabled, and I could not turn the vehicle off by pushing the start/stop button once, I had to use a procedure that forced the vehicle to shut down. My interior dash lights flickered, I'm not sure if the headlights worked. As the interior dried out, the flickering occurred less frequently. I was able to drive the vehicle to a Honda dealer for repairs.

The front camera that regulates the adaptive cruise control failed. Now it does not allow for any of the safety features to work. I’ve gone on multiple Honda forums and a lot of people have the same issue.

Driving on the interstate with cruise control. All of a sudden the car braked (no one in front within eye shot) and cruise control stopped. I had to tap the brake manually then accelerator to get the car back under my control. Ever since then I get acc, lkas and other warnings when the car starts up. It seems like the front camera catastrophically failed while driving and almost caused the car to come to a complete stop on the interstate. It was very scary.

All the systems are not working this is a very low mileage vehicle and has not been involved in any accidents. They are many owners reporting the same issue. This is a safety issue as it shuts off many of the safety features of this vehicle while driving. Honda claims it’s normal.

Several of my warning lights came on related to safety features such as brake assist, lane assist, collision mitigation. Brake warning. The source has been identified as a failure with the multipurpose camera unit.

Automatic emergency braking, forward collision warning, and lane departure warning systems stopped working simultaneously without warning. Upon further investigation, failure of the forward-facing camera is the likely root cause. Based on conversations in internet discussion forums [xxx] , [xxx] ), this is a common failure. There was a recall for the Odyssey to fix a wiring harness issue that could affect the back-up camera. I believe loss of the automatic emergency braking, forward collision warning, and lane departure warning systems is much more serious, with potentially catastrophic consequences. Since evidence suggests failure of the forward-facing camera happens frequently, I believe this issue should be treated with the same gravity as the back-up camera and a recall should be issued.

Mass safety system failure due to front projector camera/ wiring harness. Noted systems below failed: adaptive cruise control auto emergency braking forward collision warning lane departure warning lane keeping assistance auto high beams all above system are not operational.

On Sunday 9/28/2025 I started up my vehicle and received numerous error messages: collision mitigation braking system (cmbs) road departure mitigation system (rdm) lane keeping assist system (lkas) adaptive cruise control (acc) brake system light I contacted the dealership in which I purchased the vehicle and they did diagnostics. It came back that the front facing camera needs to be replaced. Which is a $2000 repair. After researching online this seems to be a common issue with years 2018-2020 Odysseys. This needs to be investigated and a recall issued from Honda USA for remedy as these error messages are concerning when they pop up repeatedly.

The forward facing camera has failed. A myriad of systems are dependent upon functionality of camera including collision mitigation braking, lane keep assist, lane departure warning, forward collision warning, cruise control, and automatic lighting and high beams. The failure also prompts a transmission system failure, though it's unclear how/why that system would be related. All issues are prompted by warning lights on the dash and the systems are inoperable. Research of the issue suggests it's a common failure across Odyssey and cr-v models with front-facing cameras and related safety systems.

Multi-purpose camera unit internal electronic failure. Front-facing camera mounted in the windshield. This caused several warning lights including the brake system warning light to illuminate. This failure caused the automatic brake system and other safety features in the car to turn off. The vehicle has been inspected by a mechanic. There were no other warning signs.

The forward facing camera failed on my 2020 Odyssey with only 90,000 miles. Because of this failure, I am loosing all my forward facing safety features. This seems to be a common issue across many Honda vehicles and most users report being told the issue is being caused by overheating. Since users are being told this is a cause and effect issue, the manufacturer should address this at their expense. I first noticed this issue in mid September 2025.

Multipurpose camera failure, all advanced safety systems were affected (adaptive cruise, lane keep assist, blind spot warning, rear cross traffic warning, auto-dim headlights, etc) also, caused engine light, brake system and transmission system errors to appear but they were cleared by replacing the camera with no apparent damage to the actual systems. Replaced at a dealership for a total cost for parts and labor $2200+.

My engine lights started flashing. I was stranded with my children. Had to coast into a nearby gas station. I’m told it’s a failed monocular camera causing all of it. When I google that it looks like it has happened to so many people! a recall needs to happen.
