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.

I randomly received a series of 6 warning messages when starting the car on 9/3/26. They were all warnings related to the automatic safety features such as lane departure, collision detection, auto bright lights, etc. I took it to the dealer on 9/4/26 & they diagnosed an internal failure with a multi-purpose camera embedded in the rearview mirror. The dealer ordered a new part, installed and reprogrammed and recalibrated the camera. This vehicle has been owned only by me, is kept in a garage away from weather exposure, there is no reason for this part to fail on a 6 year old car with a hefty cost to the consumer.

?I am writing to issue a formal complaint regarding gross negligence, logistics failures, and deceptive service practices surrounding mandatory recall work on my 2020 Honda Odyssey. ?1. Failure to complete recall software work after overnight retention on Tuesday, September 1, your service department texted stating: "the software update did not finish. We do need it overnight. " we agreed to leave the vehicle. However, upon pickup, the infotainment display confirmed that the update was never completed and remains stuck at step 5/6 (system update 24084. 7 / front control box b. 1. 4. 6). Retaining a customer's vehicle overnight under the guise of completing software work and returning it unfinished is a direct misrepresentation of labor performed. ?2. Extreme logistics failure and disregard for customer time at 12:55 pm on Wednesday, September 2, your department texted: "ready to go now!" my wife arrived promptly, yet your staff forced her to wait until 2:40 pm—nearly two hours later—before physically releasing the car. This gross delay caused her to miss our children’s school pickup, forcing me to leave my workplace unexpectedly to handle child transportation due to your operational incompetence. ?3. Cascading network faults and critical safety systems disabled prior to service, the dashboard displayed minor sensing suite warnings, for which your department quoted an exorbitant $250 diagnostic fee. Upon picking up the vehicle, the dashboard warning count escalated from 5 to approximately 9 active system failures. Due to the interrupted ecu software installation corrupting the can-bus network, the following primary vehicle controls are now completely inoperable: ?supplemental restraint system (srs / airbag) (newly triggered post-service) ?vehicle stability assist (vsa) system ?automatic brake hold system ?electric parking brake (epb) system ?electric power steering (eps) ?hill start assist ?Honda sensing suite (lane departure, collision mitigation, road departure) ?releas.

Ton of warning messages displayed related to adas systems not working. Took car to the dealership and was told the multicamera system failed. Messages almost identical to what's reported here and apparently many other Honda owners are reporting the same problem. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Multipurpose camera on the Honda safety sensing system has failed. There are no warnings for blind spots or lane assists. My daughter will be driving this car. Confirmed by a service center with a diagnostic completed. No warning signs prior to failure. It failed on 8/30/2026.

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

My entire adas system malfunction and it started listing 7 warning alerts. I googled and it seems like is a common theme with this vehicle.

The monocular camera failed causing the car to lose all adas features. Honda said this not a recall issue and I have to pay for the repair which is significant. Not only are all the adas features lost, but the dashboard flashes warnings and beeps reflecting the lost features.

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.

When I start the car, I get 8 or so warnings: adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning, lane keeping assistance, etc. The air bag warning for passenger also blinks. The dealer indicates this is a faulty front camera and will require about $2500 to fix it.

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.

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.

Camera failed after 65,000 miles and is a known problem out there with thousands of these requiring a $2000 dealer replacement.

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!.

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.

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.

Safety mitigation compoments failure that started as intermitent issues and now is consistent. Warning lights come on for adaptive cruise control failure, forward collision failure, lane departure warning failure, high beam failure, lane keep assist failure and others all link back to the dtc u3000-49 internal multipurpose camera unit failure. This compenet failure puts all oppcpants and other vehicles at risk as driver have become reliant on all feature working properly to enhance safety for all. The problem has been diagnose and inspected by two different dealerships. No accident or vehicle comprimised, the camera component just fails and have talked to two other familes that have had same issue. The issues started as a inteitent flsh of all the warning lights and that moved to a constant issue. Currently you can drive the vehicle for a various amount of time and eventually the lights will go on or the dash will be lit up like a christmas tree as soon as you turn it on. Concerned as this is a vehicle that a majority of moms and kids drive in, as is the case for our familiy.

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.

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.

I am reporting a safety-related defect involving my **2019 Honda Odyssey ex-l** (VIN: **5fnrl6h76kb029137**) with approximately *,156 miles**. **"brake system"** warning message appears first. Within seconds, additional warnings appear one at a time for **adaptive cruise control (acc), lane keeping assist system (lkas), collision mitigation braking system (cmbs), road departure mitigation (rdm), and automatic high beam**. All of these safety systems become unavailable. The vehicle continues to drive and brake normally, and the speedometer functions correctly. The blind spot information system and rear parking sensors continue to operate normally. A diagnostic scan performed by a vip Honda mechanic identified **diagnostic trouble code u3000-* stored in the **front multipurpose camera module**, indicating an internal camera module fault. The battery and alternator have been tested and are operating correctly. The vehicle has its **original windshield**, has **never been involved in a collision**, and there are * signs of water intrusion** around the front camera assembly. This failure occurred suddenly during normal driving without any known external cause. The failure disables multiple collision avoidance and driver assistance systems that are intended to help prevent crashes. Because these safety systems become unavailable during normal vehicle operation, I believe this represents a potential safety defect that should be investigated. I have notified Honda of this issue and opened **american Honda customer relations case #165-16502**. Honda is currently reviewing the matter for possible goodwill assistance. I respectfully request that NHTSA investigate whether similar front camera module failures (dtc u3000-49) are occurring in other 2019 Honda Odyssey vehicles equipped with Honda sensing.

U3000-49, multipurpose camera unit internal failure, no impact, no glass work.

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 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.

Front camera intermittently works after NHTSA recall number 26v-227 software update. Adas systems may turn on or off while driving. This issue may not have anything to do with the update, but Honda is aware of the front camera problem. Affects: auto high-beam problem adaptive cruise control problem lane keeping assist problem collision mitigation system problem road departure mitigation system problem there has been a class action lawsuit filed against Honda by California June 2026.

I am the original owner of a 2020 Honda Odyssey elite. On July 7, 2026, at approximately 76,127 miles, five safety-system warning messages suddenly appeared simultaneously upon startup: adaptive cruise control problem, auto high beam problem, road departure mitigation system problem, collision mitigation system problem, and lane keeping assist system problem. Restarting the vehicle several times did not clear the warnings. After the vehicle sat for approximately 30 minutes, the warnings disappeared. On July 8, after driving approximately 400 miles home, I parked the vehicle outside in approximately 110-degree heat. About two hours later, upon startup, the same five warnings reappeared simultaneously, along with the brake system warning light. An authorized Honda dealer confirmed the multiple warnings and performed a dtc scan. Code u3000-49 was stored, indicating an internal failure of the multipurpose camera located behind the rearview mirror. Further testing confirmed that camera replacement was required. The dealer replaced and recalibrated the multipurpose camera at 76,567 miles. The repair cost was $1,631. 80 for parts and $717. 50 for labor, totaling $2,349. 30. I am concerned that failure of a single internal camera component simultaneously disabled multiple driver-assistance and collision-avoidance safety systems. I believe NHTSA should investigate whether multipurpose camera failures associated with dtc u3000-49 represent a recurring safety defect in 2020 Honda Odyssey vehicles.

I have 2019 Honda Odyssey and my front windshield camera shows multiple lights also nothing works there are shows 11 working lights also I go dealer and they toll me you have to replace your windshield camera and it cost $2200 and not only me there are so many people facing that same problem plz give a recall for Honda Odyssey year 2018 2019 & 2020.

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/.

On 5/28/26, I went to get my van checked at a repair shop through my healthcar warranty and I was told that I needed a system update on my brake system/adas/lkas/acc systems. All the lights beeped and were lighting up on my dash. It would go on and off from time to time, usually when it was more hot out. They told me to take to dealership and they need to do a system update and should fix no additional charge. I took it to the Honda dealership service department on 7/6/26 and was told it is the multipurpose camera has an internal failure and it would cost me $2,443. 00 to repair it, plus I had to pay them a diagnostic fee. I have researched and been told by other repairs shops that this problem has been occurring often and it seems due to heat is the reason this happens.

My van is suddenly giving me warnings that include collision mitigation, road departure mitigation, adaptive cruise control, lane-keep assist, brake hold system, and traffic sign recognition. My safety is at risk if the front camera system is not working/faulty. I was unaware of the problem and had my cruise control on when it just went off and there were warnings popping up on dashboard. There was a class action lawsuit filed against Honda on 7/2/26 in CA for certain Honda vehicles. I have had my van put on a computer that has given us the error code and is a front camera failure. The issue first appeared on 7/2/26. It will suddenly start flashing warnings when I’m driving. It will also flash warnings right after I start the vehicle.

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 have received warning lights associated with safety features controlled by front facing windshield camera indicating that the acc, auto braking, lane departure and front collision avoidance features were not working. This has happened once before just over a year ago and I was told by the dealer that the camera needed to be replaced. I did so, at a cost of over $2k. All features worked again after the costly replacement, until last month, just outside of the one year warranty on the new camera. This is clearly an issue with either the camera or a connected electrical issue. This van also has a breach in the body wields at the rear lift gate opening in which water is able to seep into the interior of the body behind the interior rear side panels. During heavy rains the carpet on the right side trunk area is wet and can be tracked to coming from behind the right rear interior molding. I have not yet removed the molding so I am unsure if any electrical components connected to the front camera and associated safety features are located there and might be causing these safety feature issues. At a minimum, both of these issues, the camera constantly quitting, as well as the breach in the body allowing moisture intrusion, should warrant a forced recall for Honda to address and correct each item.

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.
