Warning Problems of Honda Odyssey - part 2

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.

See all problems of the 2018 Honda Odyssey 🔎.

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.

All warning lights came on for adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. Based on my research, it seems the forward facing camera has failed. The vehicle only has 37,000 miles on it and it is only 5 years old.

I in August 2025, I experienced a sudden and complete failure of the forward-facing windshield camera in my 2018 Honda Odyssey, which disabled multiple safety-critical systems. After having new tires installed at discount tire in preparation for a road trip, I started my vehicle and was immediately confronted with multiple dashboard warnings, including: •“road mitigation system problem” •“auto high-beam problem” •“adaptive cruise control problem” •“lane keeping assist problem” •“brake system” I took the vehicle to a Honda dealership. They diagnosed dtc u3000:49 — internal failure with multipurpose camera unit and informed me the only repair option is to replace the camera and perform camera aiming. The quoted repair cost is approximately $2,000. The dealer explained that this failure is “common in hot climates. ” if true, this represents a serious design flaw. The Odyssey was marketed as a family vehicle equipped with advanced safety systems, yet a single component failure suddenly disables nearly every major driver-assist safety feature. This is a serious safety defect for several reasons: 1. Safety systems suddenly fail without warning. One moment the systems are working, and the next they are completely disabled. A driver relying on lane keeping, collision mitigation, or adaptive cruise control would be placed at immediate risk. 2. Known widespread issue. The dealer admitted this happens in hot climates, suggesting Honda is aware of the problem but has not addressed it. 3. Unreasonable repair cost. A vital safety component should not have a built-in failure mode tied to environmental conditions, forcing owners to pay thousands out of pocket for safety-critical repairs. 4. Loss of federally encouraged safety features. Forward collision mitigation and lane departure warning systems are strongly promoted by NHTSA itself. Their failure removes protections drivers expect when purchasing the vehicle. This issue appears to be a common defect in Honda Odyssey vehicle.

All of the warning lights associated with advanced safety features came on on the way back from a visit to local store. When checking the codes there is a the u3000-49 code indicating an issue with the mono camera or radar unit. These warnings do not allow for the use of any of the safety features affected. The code cannot be cleared from the system either.

The forward-facing camera and/or radar unit failed one morning while running errands, resulting in 5 separate adas system failures. With these safety features not working, our safety and the safety of others is at risk. We took it to our dealer and were told we would have to pay a diagnostic fee of $205, even though they clearly already knew what the problem was- based on the multiple complaints through NHTSA and various other forums and websites from Odyssey and other Honda model owners and across multiple years. The problem was confirmed by the dealer and they quoted us $2025 and we're still not sure if that includes just the camera and/or the radar unit, which is another $600 part. Other dealers have quoted only $1200 to fix the exact same thing, with others charging more than double that. The 5 separate warning messages scroll across our screen repeatedly and are very distracting as you're driving. With multiple electrical issues already in recall status by Honda, this is another one that they should be taking responsibility for and not dumping this defective electrical repair on their customers. Who's to say that we won't be in this exact same predicament 3 or 5 years from now if the part or parts aren't fixed! definitely expect more from Honda. . . Very disappointed and feel betrayed by the inferior parts they're passing on as quality products.

While driving, all at once several messages displayed, all of which are related to forward facing camera. Adaptive cruise control problem, collision mitigation system problem, road departure mitigation system problem, auto high beam disabled along with the brake system light turning on when I researched the internet, there are alot a people report this problem with the Honda forward facing camera witch supports the systems listed this failures. Talking to friends and neighbors they have had the same issues, it is about a $2000 fix to replace and recalibrate the camera link to user forum [xxx] most of the reported issues including mine are related to heat, the camera is in an enclosure located at the top center of the windshield. We just had heat indexes above 100 degrees. The camera is always hot to the touch. I also had this issue in the past put happened whole under warranty. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

All Honda sensing technology is not working and brake system indicator is on. Acc, lkas, collision mitigation, auto high beam, road departure. I read online that a lot of Honda Odyssey owners are experiencing same problem. It could be the front camera sensor. I have always had electrical problems with car. There crackling sounds when the radio or music is playing on the stereos.

The front camera is malfunctioning, affecting all of my safety sensors.

The sensors in the rear view camera and the grille are malfunctioning causing my van to throw error messages for the adaptive cruise control, lane assist, automatic high beam and brake light to stay on. Theres a risk of accidents happening if the van doesnt notify the driver of lane departure at the right time.

After two months of sitting outside in the arizona sun, the transmission was replaced on my 2019 Honda Odyssey. A day after picking it up all of the sensors came on. I have been informed that it’s an internal failure with the adas camera that’s housed in the windshield. After a brief web search, this seems to be a common issue related to electrical issues with the car. Since the electrical was connected and disconnected during the transmission replacement begs to reason that there was something faulty about this camera that didn’t make its way through the reset.

With no external cause the multifunction camera/radar stopped working at ~59000 miles almost immediately after we purchased it (used). Problem may have been disguised by dealer and occurred earlier. Oly fix is a $2000+ replacement. Automatic braking, cruise, lane keeping, collision alerts all disabled.

I recently replaced a battery on the 2018 Honda Odyssey. When I turned the car on, the dashboard showed 6 issues: adaptive cruise control problem; lane keeping assist problem; collision mitigation system problem; road departure mitigation system problem; auto high beam problem; and the brake system light was on. I paid a mechanic to clear out the code and the was told that the front sensing camera needs to be replaced. Without a replacement, all these errors will continue to show up. I search online to find out if other people have had this issue because it was just too coincidental that a battery replacement broke the front camera. I found posts by many people who own the 2018 Honda Odyssey having similar or near identical issues that I have had. The cost to replace the camera and have it recalibrate it is going to cost $1,800. 00 as estimated by a local Honda dealer. The Honda dealer told me that they have seen this problem over and over again.

On random occasions all of the above warning lights come on. They will stay on for weeks at a time despite replacing the battery and following all reset protocol. It seems when weather is cooler, everything functions as it should and cam work fine for days and out of the blue will throw all the alerts again making lane assist, cruise control, and all departure assists not function. Because the system works sometimes and not others, the Honda dealership doesnt believe it is an issue with the camera or sensor specifically because it would never work properly. It isnt an obstruction issues as I make it a point to regularly clean the sensor area on the grill and on the window where the camera is. A strange thing I notice is it seems 5o work better on days that are foggy or raining where youd think there would be obstruction. Its just been a whole distraction while driving. I would be content at this point just to have those options not function ever but keep the orange blinking annoying lights off that decide to work randomly with no reason or rhyme.

Brake system light, and other warning lights including adaptive cruise control, lane keeping assist, collision mitigation, road departure warning, and auto high beams: a common issue from internet which likely be caused by the camera/sensor issue (near the rearview mirror).

While driving on the interstate (60-70 mph) in very light traffic (2 cars in view), there was a beep from the consol and the following errors flashed: adaptive cruise control, forward collision warning, lane departure warning, lane keeping assistance warning. At the same time as the beep the car felt like the breaks were being slammed on for 2 second. There was no car within 30 feet of us. And we went from ~70 mph to 40. This startled us. Ever sense then the errors would randomly come on and the vehicle will break suddenly, leading to very unsafe moments.

The multipurpose camera unit failed in my 2020 Honda Odyssey. This camera is responsible for enabling multiple advanced driver-assistance systems, including the collision mitigation braking system (cmbs), lane keeping assist system (lkas), road departure mitigation system (rdm), adaptive cruise control, and auto high beams. The component has not been replaced yet and is available for inspection upon request. The failure of the camera disabled multiple critical safety systems while the vehicle was in operation. These systems are designed to prevent lane departures, collisions, and unintentional road exits, especially at higher speeds. With the systems offline, I was at increased risk of collision or lane departure, particularly on highways or in low visibility conditions. This malfunction removed key layers of protection that the vehicle is designed to provide. The issue was confirmed by a Honda dealership on August 8th 2025, which diagnosed the problem as a failed multipurpose camera unit. They acknowledged that this malfunction disables all related safety systems. The vehicle was inspected by a certified Honda dealership technician, but not by police, insurance, or the manufacturer directly at this time. Multiple dashboard warning messages appeared simultaneously one day when starting the vehicle, including: "collision mitigation system problem" "road departure mitigation system problem" "lane keeping assist problem" "adaptive cruise control problem" "auto high-beam problem" these messages first appeared on or around the end of June 2025, and the systems were disabled immediately upon the failure.

My Honda Odyssey, after a hot summer day showed error codes related to the front camera. The adaptive cruise control problem (acc), auto high-beam (a); road departure mitigation system, collision/braking mitigation system; lane keeping assist problem (lkas) now are non-functional. Various internet users complain of the same issues without a conclusive source for the problem. It is either related to battery voltage or front-camera failure (possible due to heat/sun exposure). The 2020 vehicle was purchased used from dealer in 2024 where the battery was stated to have been replaced/new. Further, my vehicle has the infotainment package (tv/dvd) which has also previously drawn down the battery even after the car was shut off (I. E. , the electronics and/air conditioning are drawing too much battery and causing low voltages that impact the camera-based sensors). Multiple internet users complain of parasitic battery draw, fuses, poor oem batteries, and faulty behaviors with the camera system.

If the car is standing in sun on a very hot day, upon starting the engine it will start beeping with all these errors blinking and disabling these controls. Once the engine runs for 15,20 minutes and the car cools down, the warnings disappear too.

The front sensor has malfunctioned and all adas features are now disabled. There is no damage to the vehicle and was mentioned that this is a common issue yet no recall has been instituted yet.
