I own a 2018 Honda Odyssey Elite. On October 5, 2026, at 120,007 miles, an authorized Honda dealership diagnosed the vehicle with DTC U3000-49, Multipurpose Camera Internal Failure. The Honda technician cleared the DTC, but it returned shortly afterward. The technician inspected the camera and connector for poor connections or damage and documented that none were found. The dealership determined that the multipurpose camera needs to be replaced and reprogrammed. I was quoted $2,350 plus tax for the repair. The failure causes multiple Honda Sensing safety and driver-assistance systems to become unavailable and produces multiple dashboard warnings, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, and related safety-system warnings. I have video documenting these warnings following the dealership diagnosis. My safety concern is that an internal failure of a single multipurpose camera can simultaneously disable multiple collision-avoidance, lane-assistance, and driver-assistance systems. I am reporting this failure so the federal safety agency has a record of the U3000-49 failure on my 2018 Honda Odyssey and can determine whether this represents a broader safety defect affecting these vehicles. The vehicle has not yet been repaired.

-multiple messages/lights on dashboard determined by dealer to be due to forward looking camera, which disables Hondas Sensing safety suite. Available for inspection upon request. -safety of myself/family and others put at risk due to distracting messages/lights on dashboard, which can also conceal additional issues not associated with forward camera. Safety features are disabled when the camera does not work properly, specifically lane assist, adaptive cruise control, collision mitigation , road departure mitigation, auto high beams. -problem has been confirmed by dealer: DTC U3000-49 -yes, inspected by manufacturer/dealership -issue appeared randomly approximately a month ago with no other warning signs
The front camera has failed so all of my forward driving safety features no longer work such as lane keep assist, adaptive cruise control and collision mitigation. Every time I turn on the engine I have multiple warning lights that appear every time that have to manually acknowledge to clear them from my dashboard.
Multiple warning lights on. Dealership told me it was code U3000-49 Multipurpose Camera mutimimillmeter wave radar internal electronic failure
All systems relating to the forward facing camera have failed.
This vehicle is actively immobilized on private residential property with its central ADAS safety networks and Advanced Driver-Assist networks completely crashed and offline (DTC U3000-49) and active short-to-ground circuit failures (DTC B2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign the federal safety agency Recall 26-V-423 (Rearview Camera Failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the Power Tailgate Control Unit and heavy corrosion on the wiring connector under a previous Repair Order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, American Honda Corporate Case Management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.
The contact owns a 2018 Honda Odyssey. The contact stated that while driving 25 MPH, the audio of the vehicle unexpectedly became inoperable. The failure was a recurring failure. Additionally, there was an abnormal burning odor inside the vehicle. The contact associated the failure with the federal safety agency Campaign Number: 23V431000 (Back Over Prevention); however, the VIN was not included in the recall. The dealer was contacted and stated that the cost of the repair was not covered because the VIN was not included in the recall. The failure mileage was approximately 90,332.
Front Molecular sensor/Camera
The windshield-mounted front monocular camera (Honda Sensing unit) overheated and failed/burnt out. This failure completely disabled the Forward Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Lane Keeping Assist, and Adaptive Cruise Control systems, triggering multiple safety system warning lights on the dashboard.
Forward Collision Warning
The monocular camera (multipurpose camera secured under the rear view mirror) has failed. This disables the following" Collision Mitigation Braking System (CMBS): Detects obstacles or vehicles ahead and helps brake automatically if a collision seems likely. Forward Collision Warning (FCW): Works with CMBS to send visual and audible alerts if you get too close to a vehicle in front of you. Lane Keeping Assist System (LKAS): Adjusts steering torque to help keep your van centered in a detected lane. Lane Departure Warning (LDW): Alerts you if you drift across detected lane lines without using your turn signal. Road Departure Mitigation (RDM): Applies steering help or braking if you drift off the paved road entirely. Adaptive Cruise Control (ACC): Maintains a safe, set following distance behind a vehicle traveling ahead of you. These systems are helpful in keeping you safe while driving. The problem with camera failing cause these system warnings to populate on the dash. This is distracting. This has been confirmed with independent service center. Has not been inspected by manufacture. Started August 21. quoted $2200 to replace and recalibrate.
The contact owns a 2018 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate, requiring the contact to forcefully depress the accelerator pedal to move the vehicle. The contact stated that multiple warning lights unexpectedly illuminated, including the Road Departure Mitigation system, Collision Mitigation Braking System, and Lane Departure Warning system warning lights, and all related safety features failed to operate. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 105,000.
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.
Our van recently started flashing multiple warning lights every time we started it up. These include "Collision mitigation system problem", "auto high-beam problem", "road departure mitigation system problem", "lane keeping assist problem", "adaptive cruise control problem", and also alerts that there is an issue with our brakes. We took the van into our local Honda dealership and were told the ADAS camera was broken and would need to be replaced. We were told this would cost $2,733 and that there's a chance we will also have to replace the windshield (which is physically fine) for another $1200. The camera breaking is not normal maintenance or expected due to wear and tear. There is nothing physically wrong with our windshield, we have had no accidents, we have kept up on all needed vehicle maintenance. It's my understanding the location of the camera is simply causing it to overheat and blow out the electrical system. Additionally concerning is that even if I did have the money to fix the issue Honda does not have any cameras available. They are on backorder. It means as a driver to three small children I have to assume the nonstop alerts are all benign for at least a month. In the off chance there is a true safety concern such as brakes malfunctioning, I will not know as the alert system is going off at all times.
while driving at 35 mph a vehicle well ahead of me made a left turn exiting the roadway. My vehicle suddenly applied the brakes even though there was no longer a vehicle in my path. I tried to increase the accelerator, but the vehicle was slow to respond to this. luckily there was not another car directly behind me. This exact problem had occurred many time previously.
The contact owns a 2018 Honda Odyssey. The contact received notification of the federal safety agency Campaign Number: 26V423000 (Back Over Prevention); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.
Every time I park the car outside in the sun these components fail and it starts working once the car is left to cool in shade … this happens even in milder temperature mid 60 to 70 deg F.
While driving the car lurches as it shifts gears. This had gone on for quite some time but no codes have been thrown. This last time the car lurched so badly at the beginning of acceleration that I thought it was going to stall. It did not, but lights began flashing on the dash and when codes were (finally) thrown I was told I needed a new transmission altogether.
Front camera failure shut off multiple safety features. Confirmed by the dealership service department. Safety features shut off adaptive cruise control, lane keeping assist, collision mitigation system, road departure mitigation system and blind spot info system. Driving this car under 43000 miles with multiple safety features off with messages flashing is stressful, distracting, uncomfortable and unsafe especially this car is mainly used for children. The worse part is that the dealership service department can not fix the problems because the part is back ordered. We have to continue to use this car in this unsafe condition.
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.
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.
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.
Component Affected: Forward-Facing Multipurpose Camera / Advanced Driver Assistance Systems (ADAS)Description of Safety Hazard: While operating my 2018 Honda Odyssey on a public road, the forward-facing multipurpose camera suffered a sudden, unprovoked internal hardware failure. This failure instantly triggered a cascade of severe dashboard warning lights and error messages. The camera failure completely disabled multiple critical active safety systems simultaneously, including: Collision Mitigation Braking System (CMBS)Lane Keeping Assist System (LKAS)Road Departure Mitigation System (RDM)Adaptive Cruise Control (ACC)Auto High-BeamsSafety Consequence: The sudden loss of these active safety technologies dramatically increases the risk of a high-speed collision, as the vehicle can no longer autonomously detect obstacles, mitigate frontal impacts, or assist with lane keeping. Crucially, the total failure of Adaptive Cruise Control left the vehicle with no standard cruise control functionality whatsoever during highway driving, creating an unexpected distraction and safety hazard. The dealership confirmed a failed front camera module and quoted $2100 to replace and recalibrate the unit. This is a systemic hardware defect affecting 2018 Honda Odysseys that requires a formal safety recall.
ADAS front facing camera died at 104,716 miles. No prior warning. All ADAS systems are down. Five emergency warnings on starting up the car. Normal driving is OK, but safety systems are no longer working. Reported repair cost from Honda dealership is $2000+.
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 .
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)
The front camera is intermittent and sometimes it works but other times I get 5 error messages when I start my car: adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation system problem, auto high-beam problem. In reviewing online, it seems like this is a very common problem with all of these models. Since the repair rate is over $1000 you’re going to have a lot of vehicles on the road without the safety features working. Since it’s intermittent, there’s something with the connection between the camera and the computer. If the camera were broken, it wouldn’t work at all. Any people say they can bang on the camera but that doesn’t seem like a safe fix. I believe this needs to be investigated.
There are multiple systems that have failed in the vehicle: — Lane Keeping Assist Problem — Collision Mitigation System Problem — Auto High Beam Problem — Adaptive Cruise Control System — Road Departure Mitigation System Problem Here’s the issue, I’ve seen multiple people with this issue saying it’s related to the camera system. I’ve reported it multiple times and to the dealer and have not received a straight answer. This needs to be investigated. How many complaints do you need to receive about safety issues in a make/model to do something about it/
I own a 2018 Honda Odyssey EX-L (VIN [XXX]). The vehicle experienced a sudden loss of power and entered limp mode, with multiple safety and driver-assistance systems shutting down at once (adaptive cruise, braking assist, lane/road departure mitigation, EPS, etc.). A Honda dealer (Allen Honda, College Station, TX) retrieved DTC P0369 and documented that the front camshaft is worn and has thrust forward, contacting the camshaft position (CMP/TDC) sensor and damaging the thrust plate. The dealer is recommending an internal engine repair costing several thousand dollars. I am very concerned because Honda has already acknowledged serious engine defects in this same J35 V6 family under Recall 23V751 (connecting rod bearing wear leading to engine damage and stall) for 2018–2019 Odyssey, yet my dealer states my VIN is “not part of the recall” and that this is a “separate issue.” In practice, I am seeing a major internal engine failure that causes sudden derate and disables multiple safety systems, but I am being told there is no recall coverage or assistance simply because my individual VIN falls outside Honda’s current recall production range. I am requesting that the federal safety agency review this incident as a potential recall exclusion problem: owners with the same engine family and serious internal failures are being denied recall coverage on a technical VIN cutoff, even though the safety consequence—loss of power and shutdown of critical safety systems while driving—is similar to the failures already recognized under Recall 23V751 and the ongoing engine defect investigation. I believe this situation may warrant expansion of existing recall coverage or a new recall campaign for currently excluded VINs like mine, and reimbursement for owners who have already paid for these repairs.

The forward facing camera that controls the ADAS system has failed leaving all of the ADAS system disabled while we drive. This all came after a certified windshield replacement by Safelite where they reinstalled it and calibrated it (according to them) but failed after their short warranty period. Unfortunately simply replacing the part is not an option as it requires calibration and special tools to get the vehicle to accept it, all while being charged by Honda an arm & leg to get.
