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.

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.

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

The monocular camera in the windshield failed and multiple warnings are present. It has been well known by multiple consumers the camera fails more often in the 2018 - 2020 Honda Odyssey.

When I turned on the ignition to drive the vehicle, multiple warning lights came on to include failure of lane keeping assistance, forward collision avoidance, adaptive cruise control, lane departure warning, and automatic emergency braking. Additionally, after acknowledging these lights, the "brake system" light remained on in the amber color. If these safety features are not working properly, it can put the occupants of my vehicle as well as others at risk.

With no preceding accident or damage, the vehicle suddenly received multiple warning lights on the dash, including: "adaptive cruise control problem", "lane keeping assist problem", "collision mitigation system problem", "road departure mitigation system problem", ""auto high-beam problem", and a brake system caution light. I attempted turning the car off and back on again, disconnecting the battery for 20 minutes, and reconnecting, and checked all fuses that were accessible. It appears the problem is related to the multipurpose camera (Honda part #: 36160-thr-a91-m1). This appears to be a common issue. This manufacturing defect primarily effects safety systems and is common on a car that is primarily marketed towards the transport of families and children. I find this defect to be unacceptable and strongly believe that it warrants a recall by the manufacturer.

Paid $210 for Honda to run a diagnostic to tell me my multi purpose camera has a failure. This has caused 11 error lights to be displayed.

Several complaints can be seen across many different Honda forums that indicate several years including 2018 - 2023 of the Honda Odyssey are affected by similar issues when the front multi-purpose camera fails. Many have reported extreme heat when physically inspecting the camera unit. The zynq xa72030 chip manufacturer, amd, has listed known issues with this particular chip overheating either due to inadequate cooling (this is a passively cooled chip), poor pcb layout, unstable or undersized power supply, all which can result in thermal shutdown. At startup my vehicle dash immediately lit up with several warning indicating the disablement of multiple systems: lkas, eba, acc, collision mitigation, lane departure, automatic high-beam. In my case, physical inspection revealed the camera outer shell to be extremely hot to the touch necessitating a rag to reduce risk of burn while handling. It's interesting to see that Honda has issues a recall for the back camera which is not tied to many or any other systems at all due to a faulty cable, yet the front facing camera which directly affects lane keep assist, emergency brake assist, collision mitigation, lane departure assist, adaptive cruise control, and automatic high-beam, has not received a recall despite the many complaints brought forth. It is clearly a defective component that affects many other systems which can lead to potential crashes under the right circumstances. I would urge Honda to issue a recall for all Odysseys experiencing multiple systems failure due to a defective multi-purpose camera.

Hello I am reporting a safety concern involving a 2022 Honda Odyssey ex-l that was involved in an accident and declared a total loss. During the incident, I was driving in snowy conditions at approximately 50 mph while entering a split lane. The vehicle began to skid, and shortly afterward I observed warning indicators activating. It appeared that vehicle safety systems, including stability or braking systems, engaged automatically. Over the next several seconds, I attempted to regain control by applying the brakes multiple times and making steering corrections. However, the vehicle did not respond as expected. Despite these inputs, the vehicle continued toward the shoulder and ultimately impacted a barrier. I was unable to regain effective steering control during this period. This raises concern about the behavior and response of vehicle safety systems, including abs (anti-lock braking system), vehicle stability assist (vsa), and related driver-assist features during loss-of-traction conditions. Additionally, I became aware of a recall affecting similar model years related to unintended or improper curtain airbag deployment due to system sensitivity. Given that my vehicle falls within this model range, I believe it is important to evaluate whether system behavior may have contributed to the incident. I am requesting that this incident be reviewed as a potential safety issue and considered alongside similar reports to determine whether further investigation is warranted.

Upon further investigation, lots of 2018 Honda Odysseys are experiencing the same problem I am. There is a leak coming in from the top of the van in the rear that causes water to leak through and overtime damages the control unit in the back. Damage to this causes my power lift gate to completely stop working, my passenger drive door to stop working, and a bunch of features like the front collision warning, the lane departure, sensors, fog lights, so on to fail and go on and off. I had problems here and there with it but it wasn’t until it rained 4 days straight that I made the connection with the leak and started trying to figure out the problem. I took it to the Honda dealership to get diagnosed and they confirmed this problem. We have not been in any accidents to cause body damage to the vehicle.

The multipurpose camera unit failed causing the forward collision warning, automatic braking, lane keeping assistance, and lane departure warnings lights to come on and rendering all those systems inoperable. Part of the selling point of this vehicle is these additional safety features and for them to fail within 5 years of owning the vehicle is a safety concern. From my own research online, it seems this is a common problem for Odysseys built around this timeframe. This part is extremely expensive and is a required repair if you want the original safety features for the vehicle. I made the repairs, but the life of these units is something that should be looked into.

Adas system, camera behind windshield. Multiple safety systems malfunctioning Honda sense with all adas safety features are not working and risk the emergency braking system to engage without reason. Caliber collison and protech have diagnosed and confirmed the problem. Honda service has confirmed no recall no warranty coverage. Quoted 2500 to fix no prior warning lights or messages. Multiple dash lights occurred suddenly and never went away.

Receiving acc, lane keep assist, front collision , auto high beam errors on the instrument screen. None of the safety features work. Cruise control does not work.

For the past 6 months the vehicle shows warnings regarding lane keeping assistance problems, cruise problems, braking problems,. The warning can show up in the middle of driving, or right at start. Sometimes they go away while driving.

While driving, the vehicle will suddenly jerk taking control of the steering. As similar defect has been noted on other models. Took to the dealership and they said it is the automatic gear box.

Went to pull into parking lot, adas system starting going crazy. Throws transmission malfunction error. Headlights won’t work - they turn on and off or go extremely dim. Van keeps jerking and losing power. Code reader showed u3000-49 electronic failure. Van drove normal, no issues until this code popped up. Issue started 01/08/2026.

After purchasing my 2020 Honda Odyssey ex-l in July 2025 (had approximately 58,000 miles), in January 2026 (current mileage approximately 66,000 miles), it suddenly displayed multiple indicators on the dash, including 'acc', 'lkas', 'brake system', 'auto high beam problem', and 'collision mitigation'. My local mechanic indicated the cause was the collision radar system, but it needed to be calibrated at a Honda dealership. My local Honda dealership indicated the problem code as 'u3000-49 internal camera malfunction', necessitating that the multi-purpose camera be replaced. The total repair cost was $2,104. 99. Online research shows that this is a common issue with this model year. If the cause is due to a camera malfunction or disrepair, and it impacts the safety of myself and others in the vehicle, why is this not considered a valid reason for a recall? I shouldn't be responsible for a costly repair that didn't result from any mechanical issue or mistreatment on my part. Because of the safety implications, this should be a Honda recall, and I should be reimbursed for the repair cost.

My multi-purpose camera system has gone bad after only 5 years. Collision mitigation, cruise control, brake system, lane keep assist, among other safety features are failing because of this.

Sensor issue that is causing safety concerns with cruise control, lane keep assistance. Forward collision issue, etc.

In December, out of the blue suddenly had rotating list of warning on dash panel (lane keeping assist problem, collision mitigation system, departure mitigation system problem, auto high-beam problem, adaptive cruise control problem) plus brake warning system light is on constantly and brake hold not working. At first this was intermittent but now on constantly when starting and driving car. Only 55k miles on my Odyssey. Dealer said he had 3 of these in the last three months. Said it was multi purpose front camera failure. Cost over $1500. Since huge safety issue putting not only my family but other cars/people at risk, we are paying to repair, however we just found hundreds of people complaining about this same issue. This should be a Honda recall. We did nothing wrong to cause this safety issue and this part should not fail in 5 years. I don't have the final invoice yet but I can upload later if required.

Honda sensing stopped working and threw a bunch of errors about acc, lkas, collision mitigation, auto high beam error, forward collision, lane keep. Apparently the camera had an internal fault without any prior warning. Also vehicle’s timing belt tensioner already deemed leaking at just 75,000 miles, well below the 100k replacement point, despite regular checks and maintenance at Honda dealers. Front suspension leaking, Honda replaced only 1, and declined to replace both, as recommended by dealer mechanic. If I did not have Honda care, I would be left with a very large repair bill for critical components of the drivability and safety of the vehicle. This is not acceptable.

Camera projector fail and 6 warning ?? lights came on, very common issue.

The multipurpose camera unit has failed resulting in loss of adaptive cruise control, lane keep assist, automatic braking and other features related to the mcu. There are approximately 6 warnings when starting the car of features not working, and 3 lights that remain lit on the dash including "brake system". This is the second time this issue has arise. The first time was replaced by the dealer under warranty.

While driving with my family, my vehicle experienced a sudden and total failure of the front-facing multi-purpose camera mounted behind the windshield. This component is the primary sensor for the Honda sensing suite. The failure caused multiple critical safety systems to become inoperative simultaneously, including the collision mitigation braking system (cmbs), lane keeping assist (lkas), and adaptive cruise control (acc). These systems are essential for crash avoidance and driver assistance.

Suddenly, all the lane keeping assistance, auto beam headlights, forward collision warning, adaptive cruise control came on. When I took it in for diagnosis, they claim that the camera assembly monocular no longer works. From searching forums, it appears this is a known issue. This is a safety issue and should be recalled.

The warning messages keep popping up regarding the lane assist system, adaptive cruise control not working and dealer states that the camera needs replacement and this is common issue for most Honda cars so should be recalled.

Since November 2025, multiple safety warning lights have illuminated upon starting the vehicle, indicating malfunctions within the forward collision warning, adaptive cruise control, and lane keeping assist systems. Two separate dealerships, reseda Honda and woodland hills Honda, conducted independent diagnostic tests. Both service centers confirmed the root cause is an internal failure of the front multipurpose camera. Consequently, the vehicle has lost critical active safety features, leaving the occupants unprotected and significantly compromising the vehicle's safety on the road.
