Assist Problems of Honda Odyssey - part 1

My vehicle suddenly developed multiple warning messages at the same time, including: brake system, adaptive cruise control (acc), lane keeping assist (lkas), road departure mitigation (rdm), collision mitigation braking system (cmbs), auto high-beam. The vehicle was taken to an authorized Honda dealership for diagnosis. The dealership determined that the front-view/multipurpose camera was short-circuiting/failing and needed to be replaced and calibrated. This concerns me as a potential safety defect because a failure of a single camera caused multiple Honda sensing safety and driver-assistance systems to become unavailable simultaneously. I am concerned that the premature failure of the front-view camera may represent a recurring safety-related defect affecting other 2019 Honda Odyssey vehicles. A failure of this component can potentially leaving drivers without safety functions they may normally rely upon. Additionally, Honda customer relations told me that several customers had contacted Honda about the issue, and the dealership told me that it had replaced front cameras on numerous customers' vehicles for the same problem. I understand that Honda has issued a separate recall involving the rearview camera on certain 2019–2020 Odyssey vehicles. I understand that the rearview camera involved in that recall is different from the front-view camera that failed on my vehicle. I mention this only as additional context because both involve camera-related components on the same generation of Odyssey. I respectfully request that NHTSA review consumer complaints and other available information concerning front-view/multipurpose camera failure on 2019 Honda Odyssey vehicles to determine whether there is a safety-related defect trend.

Failure of the front multipurpose camera which helps control functions such as automatic braking, lane keep assist, automatic cruise control, lane departure, etc.

2019 Honda Odyssey ex : sensing camera located behind front windshield failed and stopped working and giving bunch of error messages. Cruise control and other saftey features operated with help of this camera stopped working. The part number is 36160-thr-a11-m1.

I went to the dealership today for my recall on the backup camera where my screen goes black in reverse. I also told me my dash lights had come on and could like lane keeping assistance, adaptive cruise control and blind spot warning. Dealership then tells me it is a faulty internal camera in the windshield and wants to charge me $2k. Is this not a recall since it happens to a significant amount of Honda Odysseys and pilots? please make this a recall as it is not safe to drive my van anymore and should be apart of the recall I took it in for.

All of the warning lights came on at the same time. The dealer says the internal front camera sensor has malfunctioned and has happened so much that the part is on back order.

Error u3000-49 multipurpose camera failure. . . Adaptive cruise control, lane assist, etc. Do not function. I cannot even get a basic cruise control to function! Honda wants $2000+ to fix this problem that has become a common problem with 2020 Honda Odysseys. Please push for a recall!.

The lkas, acc, aeb, automatic high beams, and other safety features that rely on the front camera all became inoperable for no apparent reason. The front facing camera seems to be the culprit. This is a known issue and Honda should submit a recall to replace the faulty camera.

On 7/28/26, my 2018 Honda Odyssey began displaying the following warning lights and system messages on the dash: •adaptive cruise control (acc) system error •lane keeping assist system (lkas) error •auto high beam system error •collision mitigation braking system / forward collision error these errors were present before I replaced the 12v battery. I had the battery tested at that time and it failed a load test, so I replaced it, expecting the adas-related errors to resolve. After the battery replacement, the original errors remained, and additional warning lights appeared, including a transmission system problem indicator and a brake system warning light. I disconnected the negative battery terminal for approximately 10 minutes in an attempt to reset the modules, then reconnected it. After reconnection and a period of idling, further warning lights appeared that had not been present immediately after the battery swap. I have not been in a collision, and there was no impact to the windshield, front bumper, or brake components at any point during this period. The vehicle’s brake pedal feel has remained normal. Because these errors were present before the battery was replaced, the battery does not appear to be the root cause, and the underlying issue affecting the acc, lkas, auto high beam, and collision mitigation systems remains unresolved. I have seen reports from other Honda owners describing similar cascading adas and system warning lights on comparable Honda models.

My Odyssey randomly began displaying all of the adas warning messages: the brake system indicator light comes on, forward collision warning, lane departure warning, lane-keeping assist, auto high beam system error, etc. These came on beginning 7/25/26 and have come on everyday since causing the entire adas system to be inoperable. There have been a few days that they didn't come on immediately. I have had a few days where they came on half-way through my drive. This is a safety issue due to a defect in either the front camera or wiring to it, a nuisance, and something Honda needs to correct. It seems to be way too common of an issue according to my research. There hasn't been any damage to the van and no reason for these to come on. I have done research and see this has happened to many people. The replacement camera is costly as well as the calibration. Therefore, I haven't taken it to the dealership but I have discussed the issue with them. They agree that the camera is getting too hot and failing, which is causing the errors and of course all of those safety features fail simultaneously.

Adaptive cruise control, lane keep assist system problem, collision mitigation system problem, road departure mitigation system problem and auto high beam problem.

Multipurpose camera stopped working. No direct physical damage to camera so it shouldn't need replacement after 6 years. Others with Honda Odyssey have reported similar defect.

The car started having the acc, lkas, collisions mitigation, auto high bam, road departure mitigation system warnings. Took it to the dealer for another repair and was told that these lights were due to the front facing camera and was quoted over $1k for repair. I’m convinced it’s electrical and not necessarily what the Honda narrative is. This model has had several issues around electrical components. Please open an investigation into this car around this issue.

Failure of the forward-looking multipurpose camera after a simple battery change. Many safety features are now inoperative including emergency braking, lane keeping assist, adaptive cruise control, among others. Ultimately, a routine maintenance item (battery replacement) is causing the failure of vehicle safety systems.

Started getting bombarded with error messages. Collision mitigation lka adaptive cruise lane departure mitigation auto high beam.

The multipurpose camera has failed. I went online saw tons of people with same issues happening right after the warranty period. Even with extended warranty they dont want to help .

I believe it is the windshield monocular multipurpose lkas acc camera. This sensor has malfunctioned for the past two moths and I've tried everything to fix it short of replacing it, which is ridiculously expensive. This is such a common problem on this make/year of vehicle. My car only has 75,000 miles on it.

My 2018 Honda Odyssey ex-l has an ongoing Honda sensing failure. Adaptive cruise control, lane keeping assist, and forward collision warning cannot be activated using their controls. No dashboard warning lights or error messages are displayed. Honda of lake jackson stated that it could not perform further diagnostics. These driver-assistance and safety features remain unavailable during normal vehicle operation. I am reporting the problem because multiple Honda sensing functions cannot be turned on or used.

Safety features disabled after battery change. Warning lights not cleared after driving the car as they should. Front mounted safety camera does not function properly and this is critical for safety. Multiple people have reported the same thing [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Rear view multipurpose camera failed.

Lights are going off like crazy, ran the code and says it needs a recalibration. Nothing happened to have warrant this.

The dtc u300-49 suddenly failed which affects many of the security systems on the 2019 Honda Odyssey. Upon research, this is very common on the Honda Odyssey caused by it overheating which seems like it should be a dangerous part. It is such an expensive part that we as the consumer have to replace and it should be Honda replacing it if it is their fault that this part fails often. I haven't replaced it as we don't have the funds to replace it, so hopefully it won't pose a safety threat as there are 5 warnings showing on my screen daily.

While driving straight on the highway on a sunny day the car left the lane on it's own, resisted attempts to get it back into the lane, and crashed into the concrete barrier after we swerved around and the car bounced around. Lane keeping assistance and automatic cruise control were active. The lane lines looked perfectly fine. A couple minutes before the accident the car left the lane unexpectedly but we were able to get back into it. Before going on the trip we took the car to the dealer and complained about issues with the car not starting after it shut off while idle at stop lights, or not starting properly, like engaging the parking brake and getting stuck, or starting and rocketing forward even when I only pressed lightly on the gas, leading to loss of traction. They checked the car and said everything looks fine and the tires have 5mm of tread and don't need to be replaced, and they rotated the tires and changed the engine oil. I'm not sure if the issue was with the power steering failing, or traction being lost, or the sensors having an issue causing the car to think the lane was somewhere else and not letting us leave where it thought the lane was. Driver has tons of bruises still and it's been over a week. The other 4 passengers seem ok. The insurance company said the car is totaled and is taking possession of the car. The only warnings lights or messages the car gave us before the accident were about the car having an issue starting back up when all the cars were beeping behind us when the light turned green, and messages about loss of traction, mainly after the engine started back up.

Drove van about 30 miles and when I cranked it back up. It cranked fine but acc, lkas, auto headlights, and braking system warnings are on. Battery tests fine and camera and emblem is clean and working manner. Not sure whats causing it. Its annoying.

All adas functions stopped working on my 2019 Odyssey during a 6 hour drive to the beach with my family of four. It appears that the multipurpose camera has failed. Some reading online suggests that this is a known thermal defect, and Honda has yet to remedy the issue. Instead opting to let the consumer replace these units at $3k per.

I own a 2019 Honda Odyssey equipped with Honda sensing. The vehicle has repeatedly displayed multiple driver-assistance system failure warnings, including “adaptive cruise control problem,” “lane keeping assist problem,” “collision mitigation braking system problem,” “road departure mitigation system problem,” and “auto high beam problem. ” the warnings initially appeared intermittently and then began recurring. In some cases, the warnings appeared at startup and remained active while driving. When the warnings are present, multiple Honda sensing safety features are disabled simultaneously. To address a possible low-voltage condition, I replaced the vehicle’s battery with a new battery. After replacement and normal driving, the warnings continued to occur. The issue therefore does not appear to be solely related to battery condition. I also observed clouding and dark spotting within the front Honda emblem that covers the forward radar sensor. The discoloration appears to be inside the emblem assembly rather than on the exterior surface. Because the radar sensor is located behind this emblem, I am concerned that deterioration of the emblem or radar assembly may be affecting the operation of critical safety systems. This failure impacts several safety-related functions, including adaptive cruise control, collision mitigation braking, lane keeping assistance, road departure mitigation, and automatic high beams. The loss of multiple advanced driver-assistance systems creates a potential safety risk because the vehicle’s collision avoidance and lane assistance features become unavailable without warning. I am submitting this complaint to document a recurring failure affecting multiple Honda sensing safety systems on my 2019 Honda Odyssey. There are numerous youtube and social media posts on the same failure for same vehicle. It seems to be an issue for 2019 year.

The monocular collision-avoidance camera 36160-thr-c01 has died on my 2020 Honda Odyssey ex-l. As a result, the following safety features have deactivated causing serious concerns for my safety on the road: acc problem collision mitigation problem lake keep assist problem auto high beam problem the car is not even 6 years old and this $1000+ defective camera has rendered my car not up to safety standards.

2020 Odyssey elite multipurpose camera unit internal electronic failure dtc u3000-49. Component is still installed and available for inspection upon request. Failure disabled Honda sensing safety systems: adaptive cruise control, lane keeping assist, lane departure warning, forward collision warning, collision mitigation braking, road departure mitigation, automatic emergency braking, and auto high-beam. Dash showed Honda sensing system failure warnings. No crash, no injury. Vehicle remains drivable but without active safety features, increasing risk of crash, especially on highway. Dealer confirmed failure and reproduced it, recommended camera replacement plus adas static/dynamic calibration, quoted $2,243. No prior symptoms, no accident, no damage, well-maintained. First warnings appeared Aug 2026 and stayed on continuously. Manufacturer was notified and denied goodwill coverage, stated out of warranty. This is a known widespread defect — same u3000-49 failure documented in NHTSA complaints 11615376, 11584269, 11603801 for 2018-2020 Odyssey, art's automotive public statement on pattern, youtube coverage 2016-2021, and ebay repair market with one seller showing 485 repairs for this exact camera and 111 watchers. Similar to prior Honda backup camera recall. Request NHTSA investigation / recall consideration.

Warnings adaptive cruise control, lane keeping assistance, collision warning systems, brake system showed up while driving the vehicle, upon further search it was found there is a common issue with Honda Odyssey's multipurpose camera, and the dealer is charging 2000$ to fix it. This is a common problem in all the Honda Odyssey. I request NHTSA to look further into this issue and perform a recall or a free of charge installation. The official Honda Odyssey forum online has countless complaints on the same issue without resolution by Honda. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. Honda designed a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, I. E. , the placement of the radar behind the large, thick plastic h emblem obstructs the radar. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a recall that permanent addresses the problem.

My 2018 Honda Odyssey with just under 59,000 miles is showing the following warnings: - acc - adaptive cruise control problem - collision mitigation system problem - auto high-beam problem - road departure mitigation system problem - lane keep assist problem. Using a code scanner, the ecu reports error u3000-49, which seems related to the multi-purpose camera unit used for all these functions. Given that this camera is used in the various safety features listed above, the current condition presents an unsafe condition for my vehicle, which has less than 59,000 miles of being driven.

Root problem seems to be the forward looking camera and/or radar, though there are 8-10 codes in total. This one looks like the primary problem: u3000-49 — multipurpose camera unit / millimeter wave radar internal electronic failure as a result, we no longer have safety features such as emergency braking, collision warning, lane departure warning, or lane keeping assistance. Additionally, cruise control is no longer available. The vehicle is still drivable, but without any of the safety features reliant upon the camera and radar. There one one trip in the last few days where everything functioned normally, but on every other trip these warnings have shown up as soon as the vehicle is started. The warnings for all of those systems are displayed in the gage cluster, as well as a “brake system” light being visible. Sometimes, when the vehicle is started, additional warnings are displayed for blind spot indicator and the transmission. There were no symptoms leading up to this. Everything worked and looked normal one morning, then suddenly appeared when the vehicle was started later that evening. We have not yet had the vehicle inspected by anyone as it’s currently a holiday weekend.

These systems randomly turn off and on while driving with no root cause. Dealership wants a lot of money to fix but they’re not 100% sure what’s causing the problem. Many 2019 Honda Odyssey owners have the same issue and there should be a recall.

The vehicle’s front camera/Honda sensing system has failed, causing multiple safety features to become unavailable simultaneously, including forward collision warning, collision mitigation braking, lane departure warning, lane keeping assist, adaptive cruise control and related systems. The failure produces multiple warning messages and disables safety systems that the vehicle was equipped and marketed with. This is a recurring issue reported by other Honda owners and is currently the subject of a proposed class action lawsuit, jones et al. V. American Honda motor CO. , inc. , case no. [xxx]. The lawsuit alleges a defective front camera system affecting 2018–2025 Honda vehicles, including the Odyssey. I believe this constitutes a safety defect because the failure can occur unexpectedly and simultaneously disables multiple driver-assistance and collision-avoidance safety systems. I am requesting that NHTSA investigate this issue and require Honda to issue a safety recall and provide a free repair. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Starting around 70,000 miles the front multipurpose camera continues to fail causing various warnings, including: - collision mitigation system problem - adaptive cruise control problem - lane keep assist problem - road departure mitigation system problem - auto high beam problem.

The electrical component is failing. I have brought in this vehicle 2 times for failed electrical issues over several years (around 2 years), and it only has 52,000 miles currently. The back up sensors no longer work, as well as warning lights for the following began to appear a year ago: collision mitigation, adaptive cruise control, lane keeping assist, road departure mitigation. Sometimes, our electrical side door will not close and will keep opening when trying to shut. This electrical issues has been draining our battery, and while driving, my car shut off in the middle of the street while I was waiting for a light. After a few attempts, I got my car started again. We replaced the battery, and a few days later the car would randomly turn on and I could not use an electrical key to open the car door. Only way to open it is with the physical key. The battery had to be unplugged in order to stop the car for randomly turning on. All electrical systems would turn on in the car, including the alarm and radio, even if the radio had been off when the car was last turned off. The car has been inspected by Honda mechanics, who told me the electrical component is dying, but they don't know why, the car isn't that old, and it has very few miles on it.

Monocular camera code set and several dash messages - failure of acc, fcw, lka.
