Assist Problems of Honda Odyssey - part 1

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

See all problems of the 2018 Honda Odyssey 🔎.

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.

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.

Started up the van and the following appears on the dash: acc problem collision mitigation problem lake keep assist problem auto high beam problem safety features unavailable when driving vehicle. In my research this issue has occurred with other owners of the vehicle as well.

When using the sensor-controlled, automatic wipers the lane keeping assist is silently disabled when the wiper speed switches to high. There is no warning or explicit notification of this other than the dashed lane markings indicator becoming "empty". There should be some on console warning that is more substantial so the driver knows they cannot rely on lane assist steering during this time.

Front camera goes bad and all the driving safety indicator lights go on. I have been reading so many problems with this. Owners complaining. They want over $2000 to replace my car is over the warranty time limit.

All of the alarm lights are going on at once, immediately when the car is turned on. This includes the collision mitigation system problem, adaptive cruise control system, lane keeping assist system (lkas), break system. I am told by my local garage that it is a Odyssey radar system failure, that probably originates in the camera or computer, but that they cannot fix it or get parts for it. It is unclear if these systems work or not.

Something is wrong with the camera and causing all warnings to go off.

Vehicle has code u3000-49 in the mcu module. All vehicle safety systems have shut down and are no longer working until vehicle is repaired (lane assist, collision mitigation, adaptive cruise control, road departure, etc. ) multiplex camera unit is on national back order with no eta available. Vehicle has 5 warning lights and multiple messages that keeping popping up on the cluster.

We began getting several warnings related to adaptive cruise control, collision detection, lane departure not working. This was due to the multipurpose camera internal failure. The camera had to be replaced by a authorized Honda dealer at a cost of $2,200. While the car was drivable no safety features related to the multipurpose camera were available. There were no indications of issues prior to the camera going bad. Due to the cost of replacement I would think that a large portion of drivers do not get the camera replaced and continue to drive the vehicle without use of the safety features provided.

My 2019 Honda Odyssey ex-l has had sporadic errors happen: adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation system problem, blind spot info system problem. These errors have shown up before sporadically and the dealer, dch Honda of oxnard was notified April 27, 2023. They could not replicate and did not respond in writing that something was wrong. The errors went away on their own. 3 weeks ago, the errors showed up again, this time also including a transmission system problem warning. The car was taken to Honda in valencia and they ran a diagnostic and recommended the transmission be replaced or they would give us $2500 for the car. We opted to have a well reputed private transmission mechanic replace the transmission. After doing so the errors are still there. The transmission system problem error even showed up sporadically the very same day we picked the car up. There is no rhyme or reason to these errors other than perhaps a faulty windshield camera, which takes 5 minutes to replace but Honda wants to charge $2k. We also experienced the delayed shifting due to the poor 9 speed transmission and vcm design. It was quite scary to have a car full of children making a left turn on a busy road and not have the car kick into gear but rather slip. Installing a vcm tuner to bypass the computer shifting helped as well as not driving the car in econ. Honda knows they made a bad car and while Honda pilots and other models have had recalls related to the transmission, I am atill waiting for NHTSA to take action and include my lemon Odyssey as well. Replacing the transmission cost me over $7k and it may not have been necessary in the end if in fact these errors were related to the camera.

For the last few days I turn on my car and get alert lights that I have problems with: the acc, lkas, collision mitigation, road departure mitigation systems and auto high beams. From online Honda forums I can see that many people have had these problems and it’s likely due to needing to have the windshield camera replaced. This is a 2020 model but I bought it new in 2021, so it is less than 5 years old and I’ve got 94k miles on it. Honda markets itself on its safety features, but nearly all of my safety features are not operating properly less than 5 years from the date of purchase, it’s a widespread issue, and Honda still has not issued a recall.

Front windshield camera failed and available for inspection if needed. All safety features tied to this camera are now disabled. Even basic cruise control is disabled. Problem has been check by a dealer with an estimated cost of $2600 to repair a simple camera module. Not inspected by police but was inspected by the manufactures dealer. I can get it inspected by the police if it helps. There are several warning lights that come up after starting the car. Even dinging when backing out of the driveway causing distractions. This is a known issue for this year Honda Odyssey van. There are lots of posts about it and how to try and fix it without the dealer charging you 10% of the cost of a 2025 model. For something designed for families this is not what I expected. This vehicles safety is impacted by the removal of these features.

Internal failure of the multipurpose camera/millimeter wave radar unit with code u300-49; available for inspection upon request. All safety features linked to multipurpose camera such as adaptive cruise control, lane keep assist, auto high beam, collision mitigation system, and road departure mitigation system are no longer functional. This problem has been confirmed at the local Honda dealership in addition to the numerous forum posts made by like Honda Odyssey owners with this same reoccurring issue. There were no warning symptoms or messages prior to failure.

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. The dealer inspected the car and confirmed the issue was a bad camera. 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".

When turning on vehicle the attached picture’s warning lights show on dashboard. Unable to reset them. Vehicles collision sensor not engaged when driving. Road departure will not activate when vehicle drifts of interstate lanes. Cruise control will not work at all. Brake system light will not reset even when brakes and fluids are good. With all these issues, vehicle safety devices don’t provide any safety. These could result in bodily injury and even death.
