What 876 owners told NHTSA about the 2019 Honda Odyssey

Collision mitigation system problem, auto high beam problem , lane keep assist problem, adaptive cruise control problem, road departure mitigation problem. All of these lights came on at the same time then a transmission problem light came on. Was told by a mechanic that Honda has an issue with a lot of these because of where it sits directly in the sun. All of these problems seem to be connected.

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.

NHTSA ODI 11746365

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

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.

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.

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

I was driving on a highway and all of a sudden, I see three warnings appearing on my dashboard - "Emission System Problem", "Blind Spot Info System Problem", "Transmission System Problem". I continued driving but then my vehicle started behaving weird. It started shaking while driving. Luckily, I was close to my exit and l somehow managed to take the exit but I wasn't able to move forward when the road was uphill. I somehow managed to park next to a house and walked back home. It was a really scare drive from the time those errors showed up to when I parked. This all happened few minutes ago. Here below is a thread where I can see others having this problem.

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.

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.

NHTSA ODI 11742461

Sensor failed, causing many safety systems to fail - front collision warning, lane keeping assistance, lane departure warning, adaptive cruise control, etc

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.

The vehicle is showing persistent electrical and communication fault codes involving the ECM, ABS, and EPS systems, including P16E2, P16E5, P16E7, P16E8, U0401, and U0416. These codes return immediately, which suggests an active fault rather than a temporary low-voltage condition. The issue appears to involve the battery sensor and/or the related communication network between control modules. Because the faults involve ABS and EPS communication, the concern is that braking-related or steering-assist systems may not be receiving correct data. This creates a potential safety risk because the vehicle may experience intermittent or unreliable control-module communication, which could affect steering assist, braking-related warnings, or overall drivability. The warning lights and diagnostic codes first appeared before the vehicle was put back into normal use and have continued to remain present. The problem has been reproducible because the codes reappear right away after being cleared. No dealer or manufacturer diagnosis has been confirmed yet, so the exact root cause remains unresolved.

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.

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.

I own a 2019 Honda Odyssey Elite with 39,000 miles on it. In January 2026, suddenly I had multiple warning lights on in my minivan related to an ADAS system failure. I replaced the car battery and later determined that the ADAS camera had failed in the car. In reading online, this is a very common issue with Hondas as the cameras are known to overheat and require replacement. Warning lights: Brake System Malfunction, Adaptive Cruise Control Problem, Collision Mitigation System Problem, Lane Keeping Assist Problem, Road Departure Mitigation System Problem, Auto High Beam Problem Before I was able to get it repaired, the van turned off suddenly in traffic twice while my wife was driving the car while also one of my children was inside, creating an unsafe condition that could have created an accident. Luckily my wife was able to get the car safely moved out of traffic and we stopped driving the car at that point. I wound up replacing the camera and and needing to get it recalibrated so that the car could be drivable. This resulted in the van not being operable for nearly a month. For a car that had 39,000 miles on it, this really should be something under a longer warranty as it could have created an unsafe driving condition for my family. Total cost to repair = $1634.22.

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.

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.

NHTSA ODI 11732600

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.

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.

NHTSA ODI 11723239

The car has started giving warnings every time I turn it on (as of 6 months ago): adaptive cruise control problem, collision mitigation system problem, auto high beam problem, lane keeping assist problem. It seems there must be a fault in the windshield camera that renders all these safety features useless. The repair shop stated that windshield camera isn’t working and is a $2k or more to repair. I am now driving a minivan that doesn’t have many important safety features and this is very dangerous.

NHTSA ODI 11720892

Front camera appears to have gone out in 2025. All safety features inoperable and constant flashing of warnings making it impossible to determine if anything is actually wrong. Collision mitigation failure, blind spot failure, transmission failure, brake system failure, blind spot. Those control etc. Honda has confirmed its issue with front camera.
