Adaptive Cruise Control problems of the 2019 Honda Odyssey - part 1

Camera malfunctions with low mileage.

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.

The camera located behind the rearview mirror is faulty. In hot weather locations (like mine in florida) it stops working. And that means all electronically assisted driving systems lkas (like cruise control, auto high beam, lane departure, auto distance monitor/collision warning, etc. ) malfunction, giving flashing messages about all non-working features. This is due to cmos image sensor degradation caused by heat exposure. Many people have expressed concerns about this on different Honda forums online. I took it to a Honda dealer and after paying a fee for diagnosis, the service manager said that when the temperature outside gets hot, they get a lot of this kind of service request. They want over $2,300 to replace the camera. They were actually puzzled why Honda does not recall this item. Honda needs to address this since it is actually safety related and indeed a faulty item. There should be no reason for people to pay this outrageous price for something that is clearly a manufacturing problem.

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.

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.

Multipurpose camera unit/millimeter wave radar internal electronic failure diagnosed with u3000-49 error code in my 2019 Honda Odyssey. The problem has been confirmed by the Honda service center and reason stated is low heat resistance. Coat of repair is approx $2000 and this is purely due to low heat tolerance levels of the Honda component.

The acc is failing in the car. It is due to a faulty radar sensor located behind the rear view mirror that according to the dealership gets to hot it the sun and begins to deteriorate.

All of a sudden, I received multiple warnings that the forward collision warning system, lane keeping assistance system, automatic emergency braking system, adaptic cruise control, were not working. After looking for this part (front camera: 36160-thr-a11-m1), I see that it is very expensive to purchase and install. More importantly, I have come to learn that this part is failing on my 2019 Odysseys. I feel that the manufacturer should be held responsible if this is such a widespread problem.

All the warning lights shows up in the dash and the problems are diferent like bad battery or front monocular camera and all the futures assistence stop working like automatic brake cruise control. . Etc.

The front monocular camera assembly (Honda part number 36160-thr-a81) on my 2019 Honda Odyssey elite failed and is available for inspection upon request. When the failure occurs, the vehicle displays multiple warning messages including “collision mitigation system problem,” “adaptive cruise control problem,” “lane keeping assist problem,” “road departure mitigation system problem,” and “auto high beam problem. ” as a result, several driver-assist safety systems are disabled, including automatic emergency braking, adaptive cruise control, lane keeping assist, and road departure mitigation, which reduces the vehicle’s active safety features and increases the risk of a collision. The warnings appear simultaneously on the dashboard while driving and remain active until the vehicle is restarted. The condition has been reproduced multiple times and has been confirmed during diagnostic inspection by a service technician. The camera failures are very common and are a design defect. The design was changed in later years but there was not a recall for the 2019 models. This is a very expensive fix and should be covered by a recall.

All Honda sensing / adas safety warnings appear at the same time while driving or shortly after starting the vehicle. When this happens, all driver assistance systems are disabled, including: •adaptive cruise control (acc) •lane keeping assist (lkas) •collision mitigation braking system (cmbs) •road departure mitigation •automatic high beam when the failure occurs, the vehicle displays multiple safety system warnings and the entire driver assistance system shuts down, leaving the vehicle without any adas safety features.

Failure of camera unit leading to all safety systems requiring it becoming non operative. Well known issue and widely reported.

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.

Vehicle was driving normally down the highway then proceeded to shutdown without warning. Suddenly all of the trouble lights appeared indicatinging engine, transmission, hill assist etc cut on without warning. The van would not drive above 55 mph when turned back on.

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

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.

Driving on the interstate with cruise control. All of a sudden the car braked (no one in front within eye shot) and cruise control stopped. I had to tap the brake manually then accelerator to get the car back under my control. Ever since then I get acc, lkas and other warnings when the car starts up. It seems like the front camera catastrophically failed while driving and almost caused the car to come to a complete stop on the interstate. It was very scary.

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.

After we took the car in all of a sudden randomly these warning lights will come on and my d for drive keeps flashing. Lkas, acc, collision avoidance, auto high beam problem and brake system warning. Sometimes some of them sometimes all of them. I read it’s a common problem but there hasn’t been a recall on it.

The camera for collision, cruise control, lane assistance and etc stopped working. Over $2000 to replace and not covered under warranty.

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.

Center camera has gone out. Millions of vans in the same position as me.

Please failure of windshield camera 36160 thr a11 has malfunctioned idas.

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.

Multipurpose camera failure, all advanced safety systems were affected (adaptive cruise, lane keep assist, blind spot warning, rear cross traffic warning, auto-dim headlights, etc) also, caused engine light, brake system and transmission system errors to appear but they were cleared by replacing the camera with no apparent damage to the actual systems. Replaced at a dealership for a total cost for parts and labor $2200+.

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.
