Assist problems of the 2019 Honda Odyssey - part 1

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.

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.

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 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.

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.

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.

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.

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

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.

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.

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.

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.

2019 Honda Odyssey began having intermittent display, that progressed to constant display, of multiple warning messages regarding safety features related to multiocular/multipurpose camera unit. Vehicle is unable to perform lkas, acc, lane departure assist, autobraking, etc. Honda dealership states this is a well known issue related to a faulty camera that has to be replaced to utilize these safety features. Without replacement, the vehicle display is overtaken by a recurring onslaught of warning messages making instrument panel difficult to view. The specific part is listed as "2019 Honda Odyssey - camera assembly monocular (rewritable) - Honda (36160-thr-a11)" and the error code is u3000-49.

When my car hit 40000 miles or so, I started getting all sorts of warning lights showing up when I turned my car on. Took my car in to Honda today, and they said upon checking it that the multifunction camera which is located behind the rear view mirror has stopped working. The car has 44,500 miles on it. It has been in no accidents. There seems to be no reason for such a part to just stop working (needing a $2500 repair to fix).

I am submitting this complaint to report a serious and recurring safety issue with my Honda Odyssey involving the front monocular camera system. After stopping for fuel and restarting the vehicle, multiple warning messages and fault codes appeared on the dashboard simultaneously, including: -collision mitigation system problem -adaptive cruise control problem -lane keep assist problem -auto high beam problem these systems are all disabled due to a failure of the front monocular camera. This failure occurred without warning and immediately compromised several critical driver-assistance and safety features. Based on my research and discussions with other Honda Odyssey owners, this is a known and widespread issue. Honda is aware that the front monocular camera is prone to failure, and numerous owners have reported identical symptoms and error codes. Despite this, no recall has been issued. The required repair involves replacement and recalibration of the front camera and carries an estimated cost of approximately $1,500, which places a significant financial burden on owners for what appears to be a known defect. More importantly, the sudden loss of collision mitigation, lane assist, and adaptive cruise control presents a clear safety concern, especially when drivers rely on these systems during normal operation. Given the safety implications and the number of reported cases, I believe this issue warrants further investigation and a formal recall by Honda. Owners should not be responsible for the cost of repairing a known defect that disables critical safety systems. Thank you for your attention to this matter.

The multipurpose camera has an internal failure at 105 thousand miles. This controls the automatic emergency braking, lane keep assist, adaptive cruise control, lane departure warning, and more. This safety features such as emergency braking, lane keep assist, and lane departure warning are important safety features. All of these features help drivers avoid collisions by acting to correct or avoid collisions or accidents faster or earlier than drivers can react. The Honda dealership service department has confirmed that the multipurpose camera had an internal failure, but did not provide a reason and there was no inciting incident during driving or ownership that caused this. The Honda dealership service department has been inspected and diagnosed that the multipurpose camera had an internal failure. No, there were no warning lamps, messages, or other symptoms of the problem prior to the failure. They only appeared after the failure, and the failure happened without warning. The failure first appeared on July 7th, 2025.

Warning for lane keeping assist, adaptive cruise control, auto high beam, collision mitigation, and road departure all populated at once. The functionality does not work, even regular cruise control without the adaptive feature. There have been many reports of this issue with fixes upwards of $3,000. Appears to be a faulty camera. This is a safety issue and should be addressed and recalled.

I had 5 warnings appeared in the dashboard : -adaptive cruise control problem -lane keeping assist problem -collision mitigation system problem -road departure mitigation system problem -auto high-beam problem and the amber brake system light came on permanently searched the problem on google and reddit found many Honda Odyssey owners having the same problem which is a safety issue some people took their vehicle to the dealership and have been told that the windshield camera is causing these warnings to appear because the camera is overheated by the sun, and the manufacturer did not make the camera well ventilated to dissipate heat caused by sun light.

5 warning shows up.

When I start the vehicle, I consistently get warnings for acc problem, lake keep assist problem, collision mitigation problem, road departure mitigation problem, and auto high beam problem. This occurs every time I have driven the vehicle for the past week. From cursory research, this issue commonly appears to be related to a failure of the camera module located next to the rearview mirror.

The brake system warning light is on. With this, it is showing 5 different issue messages when the car is running. I've taken to the dealer and they are saying there is an issue with the multipurpose front camera. My car is on 39,900 miles.

Warnings displayed: 1. Auto high-beam problem 2. Adaptive cruise control (acc) problem 3. Lane keeping assist system (lkas) problem 4. Collision mitigation system problem 5. Road departure mitigation system problem 6. Brake system warning (red brake light illuminated) dealer diagnostic: multipurpose camera malfunctioning. Costs $2218 to replace. This should be a manufacturer recall.

Front camera stopped working, which appears to be a common problem for Honda, and deactivated all safety features that rely on camera.

Took the van to the dealership to fix a recall for the fuel pump. A few days later, error messages popped up saying there are problems with the adaptive cruise control, collision mitigation system, lane keep assist system, and brake system, among others. I test drove it from arcadia to pasadena on both the freeway and the sidestreets without any problems. We took it back to the dealership who assessed it and told us that the multipurpose camera was bad. It would cost us $2100 to get it fixed. We refused. No one was hurt, however, the dealership told me that there is a safety risk to my family if I did not repair it. Attached is the invoice for the last visit during which the dealership gave us the estimate for replacing the multipurpose camera.

Upon starting the car, multiple alerts came on the dashboard reporting faults with multiple systems. There was no damage to the car, it had been parked safely and appropriately prior to starting. Dealership inspected the issue and reported the camera/sensor system in the windshield behind the rear view mirror is faulty. This faulty camera now causes multiple systems off line as the sensor is no longer reliable. This is a safety issue as this sensor assists with split second support to the driver to prevent collisions, leaving your lane or speed adjustment with cruise control.
