Warning Problems of Honda Odyssey - part 1

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

See all problems of the 2020 Honda Odyssey 🔎.

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 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.

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.

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.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

I have 6 error lights on my dash board. Road departure mitigation system problem, auto high-beam problem, collision mitigation system problem, lane keeping assist problem, ada pat I’ve cruise control problem. My car was rear ended from an insured from utica national insurance group. After my car was rear ended these error message came up. They fixed the car but refused to fix to have the lights removed because they said that these error lights do not come on after a rear end accident.

I’m have had trouble with the infotainment center since less than 5,000 miles. Supposedly it was fixed during a recall. I still have issues with it. Shortly after the recall was done, I started having all kinds of dash lights come on. Transmission system problems, adaptive cruise control problems, lane assist problem, emergency breaking problems, forward collision problems, and so on. All together, they are about 7 different lights. The rear air/heat no longer work at all. Every so often, I crank it and the radio is black. Won’t work unless I restart the car. Auto headlights no longer work. Side mirrors no longer adjust. Sunroof will no longer open. Interior lights don’t work. Automatic doors and trunk lift do not work. I can’t even lock the van anymore. When I crank it, I have to hold the key fob on the ignition button and press 3 or more times before it cranks. Switch batteries in the key fob and still no different. I paid a lot of money for this van after never having one issue out of my 2014 Odyssey. The 2020 has been nothing but a nightmare since a month after I purchased it. I will never buy or recommend a Honda vehicle to anyone. In fact, I will discourage anyone who tells me they’re thinking about a Honda purchase. I am now stuck with a barely working vehicle because who can afford another car in this economy?.

On September 1, 2025 the front windshield camera on my 2018 Honda Odyssey failed, part #36160-thr-a03-m1, resulting in the loss of many of my vehicle’s safety features including: adaptive cruise control, emergency braking, forward collision warning, lane departure warning and lane keep assistance. The camera is available for inspection. Now when I start the vehicle it displays warnings that none of the above safety features are functional. I contacted 2 local Honda dealers, bellingham Honda and burlington Honda in washington state. Both dealers said they could not fix my car since the camera is not available, since it is not in stock and on national back order, with no date of when a new camera would be be available. I have also contacted 2 online Honda parts distributors and they also say the camera is in national back order and not available, with no date of when it would be available. The result is that my vehicle has most of it’s safety systems inoperable and it can not be repaired, since a new camera is not available, and Honda cannot provide me a date when the part is available and my vehicle can be fixed. I see on the internet the front camera failure is a common occurrence in 2018 Honda Odyssey’s and request NHTSA investigate make Honda recall these vehicles to fix the safety problem.

The front-facing camera responsible for detecting surrounding traffic is malfunctioning, which in turn compromises several critical safety systems. These include adaptive cruise control, lane keep assist, blind spot monitoring, automatic emergency braking, forward collision warning, and lane departure warning. All of these features depend on the proper functioning of this camera. The vehicle has never been involved in a collision, and the camera was neither abused nor damaged. The failure occurred suddenly and without warning, triggering multiple warning lights on the dashboard. While the vehicle remains operable, all advanced driver assistance systems are currently disabled. It is my contention that Honda has engineered a defective camera system that requires a substantial out-of-pocket expense for vehicle owners to repair. I believe this cost should be borne by Honda, not the consumer. Accordingly, I am requesting that the NHTSA investigate this issue and require Honda to implement a recall that permanently addresses the problem.

The camera sensor is malfunctioning. It is affecting the collision sensor and lane assist sensor. Also adaptive cruise control, road mitigation and auto high beams. My vehicle is scheduled for diagnostics with a dealer, but seeing the many, many cases and videos online of the same problem, I am certain of the problem since it has been confirmed by others who have already paid for this costly repair. My warning lamps come on every time I start my vehicle. This is a definite safety issue since the issue is with the safety sensors.

Unknown, though others who have reported this problem are saying the front camera and it's calibration are at fault. Currently, 5 systems (3 reported + 2 more) are under warning on my vehicle due to this unknown issue and the dealership wants a ridiculous amount of money to fix even though it appears to be very common and frequent as these vehicles get more and more miles on them.

The windshield-mounted front camera assembly (part number 36160?thr?a81) that powers lkas, acc, collision mitigation, auto high beam, and other safety systems has failed on my 2018 Honda Odyssey. When the camera fails, multiple critical safety systems become disabled at once, posing a significant risk to driver and road safety. " supporting evidence from other owners: Honda Odyssey owner posted in a parts-related forum: > “the Honda garage wants $1. 5k to replace the front camera, but I’m wondering why it catastrophically failed after 3. 5 years and 30,000 miles!” a documented complaint filed with NHTSA highlights a very similar situation: > “all Honda sensing technology is not working… acc, lkas, collision mitigation, auto high beam… many warning lights appear on the dash… diagnostics… indicated the issue may be related to a manufacturer defect… dealership… said the monocular camera was defective… the contact… replaced the defective monocular camera, … once the repair occurred, all of the messages and lights… cleared and all of the safety systems… are now working correctly. ” costs: owners have reported paying approximately $750 for the camera part and another $500 for calibration, totaling around $1,250. We have even been quoted $2,500 to replace the front camera. Safety risk: the failure disables multiple driver-assistive safety systems simultaneously, increasing risk of collision — especially since these systems (acc, lkas, collision mitigation) are intended to help prevent accidents. Conclusion / call for action: given the frequency of similar reports, recurring nature of the front camera failure (36160?thr?a81) in 2018–2019 Odyssey models, the high cost of repair, and the safety-critical systems that fail when this component fails, I believe this qualifies as a design or manufacturing defect. I respectfully request that NHTSA investigate this issue and consider issuing a recall for affected vehicles.

1. Vehicle information year / make / model: 2018 Honda Odyssey touring mileage at time of incident: approximately 123,952 miles purchased new or used: used 2. Incident summary on June?13,?2025 upon starting the vehicle for the first time that day (vehicle is garage kept, year round, at home when not in use), problem codes for the auto high beam, adaptive cruise control (acc), lane keeping assist system (lkas), collision mitigation braking system (cmbs), and road departure mitigation (rdm) showed on the display and all features failed to function. 3. Detailed description of failure & safety risk (chronological) component/system affected: I have not taken the vehicle to the local Honda dealership as yet as I plan to schedule an appointment during the week of 17 August. After researching this issues it is found that many other consumers have experienced the same issue and confirmed that it was the adas front-facing camera and radar sensor failure. Due to the failure this causes the following safety systems to cease functionality: auto high beam, acc, lkas, cmbs, and rdm. Vehicle is available for inspection upon request. Safety risk: all affected systems are critical for maintaining lane position, speed, collision avoidance, and visibility. Not having these critical safety features creates a heightened risk of collision or unsafe maneuver. Inspection: only an authorized Honda dealer will inspect/diagnose the issue. There has been no inspection from the vehicle manufacturer, law enforcement, insurance, or independent service.
