Adaptive Cruise Control Problems of Honda Odyssey - part 1

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.

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.

Multiple warning lights, all for the safety system: acc, automatic emergency braking, etc. I am told by the dealer that this is due to a faulty forward camera. Looking at the NHTSA site and other forums, this is a very common issue and should be addressed.

While driving, the vehicle will suddenly jerk taking control of the steering. As similar defect has been noted on other models. Took to the dealership and they said it is the automatic gear box.

I am submitting this complaint to report a serious safety defect involving my Honda Odyssey equipped with Honda sensing technology. During normal operation and without any accident, impact, windshield damage, repair, or environmental event, all Honda sensing safety systems suddenly and simultaneously stopped working. The disabled systems include collision mitigation braking system, adaptive cruise control, lane keeping assist, road departure mitigation, forward collision warning, and related camera- and radar-based features. Multiple warning messages appeared, and the vehicle effectively lost all advanced driver-assistance and collision-avoidance capabilities at once. This occurred without warning and without any action on my part. This failure is extremely concerning because Honda sensing features are marketed and relied upon as critical active safety systems intended to help prevent or mitigate crashes. A sudden, total loss of these systems materially reduces vehicle safety and places occupants and other road users at increased risk. A safety system that can fail entirely and unexpectedly—absent any triggering event—indicates a potential systemic defect, not routine maintenance or wear. I am concerned this issue may affect other Honda vehicles equipped with Honda sensing and may be related to a common failure in cameras, radar units, software, or vehicle electronics. I respectfully request that NHTSA review and log this complaint, investigate this failure pattern, and determine whether a defect investigation, service bulletin, or recall is warranted in the interest of public safety. Vehicle details: make: Honda model: Odyssey model year: 2020 mileage: 87000 VIN: [xxx] thank you for your attention to this serious safety matter.

Went to pull into parking lot, adas system starting going crazy. Throws transmission malfunction error. Headlights won’t work - they turn on and off or go extremely dim. Van keeps jerking and losing power. Code reader showed u3000-49 electronic failure. Van drove normal, no issues until this code popped up. Issue started 01/08/2026.

My multi-purpose camera system has gone bad after only 5 years. Collision mitigation, cruise control, brake system, lane keep assist, among other safety features are failing because of this.

Vehicle was driving normally down the highway then proceeded to shutdown without warning. Suddenly all of the trouble lights appeared indicatinging engine, transmission, hill assist etc cut on without warning. The van would not drive above 55 mph when turned back on.

Sensor issue that is causing safety concerns with cruise control, lane keep assistance. Forward collision issue, etc.

In December, out of the blue suddenly had rotating list of warning on dash panel (lane keeping assist problem, collision mitigation system, departure mitigation system problem, auto high-beam problem, adaptive cruise control problem) plus brake warning system light is on constantly and brake hold not working. At first this was intermittent but now on constantly when starting and driving car. Only 55k miles on my Odyssey. Dealer said he had 3 of these in the last three months. Said it was multi purpose front camera failure. Cost over $1500. Since huge safety issue putting not only my family but other cars/people at risk, we are paying to repair, however we just found hundreds of people complaining about this same issue. This should be a Honda recall. We did nothing wrong to cause this safety issue and this part should not fail in 5 years. I don't have the final invoice yet but I can upload later if required.

Camera projector fail and 6 warning ?? lights came on, very common issue.

The multipurpose camera unit has failed resulting in loss of adaptive cruise control, lane keep assist, automatic braking and other features related to the mcu. There are approximately 6 warnings when starting the car of features not working, and 3 lights that remain lit on the dash including "brake system". This is the second time this issue has arise. The first time was replaced by the dealer under warranty.

The front facing camera has stopped working. Anytime we turn the vehicle on we get multiple warning lights (lane assist, cruise control, bright lights, braking, etc) aren't working.

While driving with my family, my vehicle experienced a sudden and total failure of the front-facing multi-purpose camera mounted behind the windshield. This component is the primary sensor for the Honda sensing suite. The failure caused multiple critical safety systems to become inoperative simultaneously, including the collision mitigation braking system (cmbs), lane keeping assist (lkas), and adaptive cruise control (acc). These systems are essential for crash avoidance and driver assistance.

Suddenly, all the lane keeping assistance, auto beam headlights, forward collision warning, adaptive cruise control came on. When I took it in for diagnosis, they claim that the camera assembly monocular no longer works. From searching forums, it appears this is a known issue. This is a safety issue and should be recalled.

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.

Multiple warnings on dashboard due to windshield camera malfunction. Many vehicles of the same model have this problem. This is a part defect and should be recalled. Thank you.

The multipurpose camera failed showing lot of error codes. This affects the braking system putting my family and kids in risk. Honda is asking 2000$ to fix the camera.

Several warnings lights appeared on the dash at the same time regarding the accident safety features including: adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning and lane keep assistance. None are currently working. The warning randomly appeared. It's associated with the camera behind the windshield and the radar detection behind the front emblem. Problem confirmed by dealer. Components have not been evaluated by anyone.

One light on dashboard lit up, started as "blind spot info system problem", light would go on and off for couple of years. Now every light on dashboard lights up, including lane assist, blind spot infor system problem, forward collision warning, adaptive cruise control problem, rear cross traffic warning, lane departure warning.

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.

Started up the van and the following appears on the dash: acc problem collision mitigation problem lake keep assist problem auto high beam problem safety features unavailable when driving vehicle. In my research this issue has occurred with other owners of the vehicle as well.

Honda Odyssey ex-l sport 2025 has been facing the issue of idle stop not working causing engine to stall, engine failing to restart, shutting off completely during mid traffic especially during adaptive cruise control operation. This is causing an unsafe driving situation. While this issue was reported to scott clark Honda multiple times and they have claimed to fix this issue in Aug 2025, the issue continues to exist and root cause hasn't been fixed. This seems to be related towards the on-going investigation by NHTSA. Please help to resolve at the earliest since no further support is being received from Honda.

The camera controlling many systems regarding safety failed and caused numerous warning lights to come on. Complete camera replacement was necessary.

After we took the car in all of a sudden randomly these warning lights will come on and my d for drive keeps flashing. Lkas, acc, collision avoidance, auto high beam problem and brake system warning. Sometimes some of them sometimes all of them. I read it’s a common problem but there hasn’t been a recall on it.

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.

Camera that controls acc lkas, lane departure, collision mitigation system, auto high bean, and braking system alerts kick out intermittently and fail to function while driving.

All of the alarm lights are going on at once, immediately when the car is turned on. This includes the collision mitigation system problem, adaptive cruise control system, lane keeping assist system (lkas), break system. I am told by my local garage that it is a Odyssey radar system failure, that probably originates in the camera or computer, but that they cannot fix it or get parts for it. It is unclear if these systems work or not.

T approximately 105 000 miles, while driving my 2018 Honda Odyssey, multiple advanced driver assistance systems (adas) malfunctioned simultaneously. The following warning lights and messages appeared on the dashboard: lkas (lane keeping assist system) acc (adaptive cruise control) auto high-beam headlights collision mitigation braking system, road departure mitigation this occurred without any prior symptoms, and the systems have remained nonfunctional since the initial incident. I did not observe any physical damage, sensor obstruction, or weather-related cause at the time. The car was in regular use and had not recently undergone service or modification. Safety concern: these systems are critical to safe vehicle operation — especially at highway speeds — and are part of the vehicle’s integrated safety design. Their sudden failure without clear cause presents a serious safety concern for the driver, passengers, and others on the road. Troubleshooting / diagnosis so far: battery is original and may be aging, but the issue persisted after a jumpstart. No recent accidents or damage. Online research shows that many other 2018–2020 Odyssey owners have reported similar simultaneous system failures, which may indicate a pattern or a design flaw. Request for action: I respectfully request the following: that Honda investigate this incident and advise if it is part of a known issue or technical service bulletin (TSB). If applicable, provide warranty or goodwill coverage for diagnosis and repair. Consider this complaint as part of broader data regarding a potential system-wide electrical/software defect.

Observed repeatedly while operating at highway/interstate cruising speed, with adaptive cruise engaged: any changes in road texture - concrete to blacktop, between different types of blacktop or concrete, separation joints, etc - such as when crossing a bridge, crossing state lines, entering open-road toll plazas, etc - results in a sharp lifting of the throttle and at times will also automatically engage the brakes. This results in rapidly and unexpectedly cutting speed by 10-15 mph before automatically resuming set speed 1-2 seconds later. This has resulted in trailing vehicles to think I am brake-checking them or otherwise caused them to abruptly brake or swerve out from behind me. It also can cause driver and occupants in the Odyssey to lurch forward and back unexpectedly - which has had a residual affect of unintended input on the steering wheel, cascading into unintended direction change and amplifying vehicle instability issues already introduced by the sudden speed change. There are multiple other owners of 2018+ Odysseys on the forum [xxx] which have reported similar situations. I have tried to encourage them to register their observations here. I believe this issue poses a significant risk to the operator and occupants, as well as surrounding motorists. Rental/fleet vehicles with drivers who are otherwise unfamiliar with the issue would be at exceptional risk. I have experienced this issue numerous times as I live near & frequent highways and interstates with these types of road conditions nearby.

Something is wrong with the camera and causing all warnings to go off.

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.

Center camera has gone out. Millions of vans in the same position as me.
