On April 20, 2026, at approximately 12:00 pm. I was driving my 2018 Honda Odyssey (VIN [xxx] ) southbound on [xxx] , approximately 3 miles north of the junction of [xxx] and [xxx] . I was traveling at approximately 30 mph. The vehicle struck a pothole in the road. Immediately upon impact, the passenger-side curtain airbag deployed with a loud report that I described as sounding like a gunshot next to my right ear. There was no collision with another vehicle or object, and no warning of any kind preceded the deployment. I was startled by the sudden deployment and noise, and the vehicle briefly swerved before I regained control. The deployed passenger-side curtain airbag completely obstructed my visibility through the passenger-side and right-rear windows. The road at that location runs along a narrow embankment with no shoulder, so I was unable to safely pull over. I had to continue driving approximately 3 to 4 miles with severely compromised visibility until I reached a safe location to park near the 9w and 340 junction. I was the sole occupant at the time of the incident. The curtain airbag deployed directly adjacent to my child’s car seat, which was installed in the rear passenger-side seat. My child was not in the vehicle at the time. Given the force and location of the deployment, a child seated in that position could have been seriously injured. Following the deployment, I experienced ringing in my right ear and ear pain that persisted for several hours. I was also significantly shaken by the incident. Component that failed: supplemental restraint system (srs) electronic control unit (ecu), which caused inadvertent deployment of the passenger-side curtain airbag. The vehicle and deployed airbag are available for inspection. Safety risk: the inadvertent deployment created multiple safety hazards. First, the deployment itself startled me and caused the vehicle to swerve at 30 mph on information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

5 alerts came on the dash stating lane keeping assist problem , collision mitigation problem , auto high beam problem, forward collision problem and brake system warning. All safety features on my vehicle have failed. I.

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.

We went to a car wash and that day after the car wash we started getting 6+ error message codes for adaptive cruise control, lane assist, lane departure, blind spot, rear cross traffic, etc. Our tech that we took it to says they have seen this happen nation wide on these vehicles.

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.

While driving on highway, multiple warnings displayed at the same time as adaptive cruise control stopped, lane keep assistance stopped and collision mitigation system stopped abruptly without warning. Independent service check confirmed the problem. No inspection performed. Vehicle has never been in a collision during ownership.

Front camera is bad or faulty, triggering all adaptive cruise control, lane keep assist, auto high beam etc errors on dashboard, rendering the car not able to start or die in the middle of the road/traffic when the engine goes into idle mode while stopping at red lights. My odessey has over 111k miles when these issues start showing, but lots of people report experiencing same issue with even with their newer odessey. It doesn’t feel right why Honda installed cheap cameras especially when it plays a crucial role involves safety of the car and the driver.

Adas camera malfunction causing all driver assist functions to not work.

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.

My vehicle started cycling between all of the check engine types of lights to include the emissions system. When taking it to my local Honda dealership, they determined that it was my front camera (multi-purpose camera internal failure). After some research and speaking to the service department, this major safety failure has been happening to many other Honda vehicles. The emissions system failure seems to also be a faulty design. I feel that the camera system failure could have resulted in an accident or major injury. And of no fault of my own. My vehicle is regularly maintained and is merely 6 years old. I should not be replacing a mayor system like the front camera every 6 years.

The multipurpose camera failed. Searches online and discussion with the dealers show this is a common problem. Result is shutdown of collision mitigation systems, blind spot indicators, lane divergence system, auto high beam, etc.

The radar is broken leaving all adas unusable in addition to no option to use cruise control.

System failure for all of the safety-related assistants. Works intermittently, but mostly indicates failure.

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.

Getting error code for safety sinsing. Lane keep assist, collision mitigation system and now transmission system. Forward facing camera is cause of issue.

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.

Intermittent electrical failure with the front monocular camera confirmed via dtc codes. Upon inspection, camera is hot to the touch and all adas systems on the vehicle cut on/off with warning lights while driving. Was going down interstate utilizing acc, system cut off throwing warning codes, then disappeared, then came back on. System continues to have intermittent issues indicating a failing camera. Even after 1-2 minutes of idle - camera is extremely hot when touching module underneath decorative garnish.

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 windshield camera completely failed. No longer have emergency braking. Honda said known problem and want to charge $2000 to fix.

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.

The camera module failed in our van and gave us a u3000-49 code which caused the vehicle to lose adaptive cruise control (acc), lane keeping assist system (lkas), collision mitigation braking system (cmbs), and road departure mitigation (rdm) functions on the vehicle with a cost to fix from Honda of $ 2,475. 56.

System is starting to fail by alerting me to clean windshield. Windshield and camera have been cleaned, still getting multiple warnings that system is shutting off safety features during my commutes.

The multipurpose camera that works to provide all the safety features failed in less than 8 years. These should be lasting for the life of the vehicle. There should be a recall for this.

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.

We turned the car on and got an acc, lkas, fcs, ahl errors due to the front sensor and the camera failing. This is an issue that many Honda owners are dealing with. The issue will not allow you to use cruise control and will disable 90% of the safety features we bought this vehicle for. The car drives fine but the safety of those in the car is affected by this error and needs to be recalled due to the number of complaints of this issue. There were no errors or warning signs prior to this happening.

Front camera is known to go out on these vans causing acc, lkas, collision mitigation, road departure mitigation system, auto high beam, transmission problems and more.

Multiple warning lights, all for the safety system: acc, automatic emergency braking, etc. I am told by the dealer that this is due to a faulty forward camera. Looking at the NHTSA site and other forums, this is a very common issue and should be addressed.

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.

I am submitting this complaint to report a serious safety defect involving my Honda Odyssey equipped with Honda sensing technology. During normal operation and without any accident, impact, windshield damage, repair, or environmental event, all Honda sensing safety systems suddenly and simultaneously stopped working. The disabled systems include collision mitigation braking system, adaptive cruise control, lane keeping assist, road departure mitigation, forward collision warning, and related camera- and radar-based features. Multiple warning messages appeared, and the vehicle effectively lost all advanced driver-assistance and collision-avoidance capabilities at once. This occurred without warning and without any action on my part. This failure is extremely concerning because Honda sensing features are marketed and relied upon as critical active safety systems intended to help prevent or mitigate crashes. A sudden, total loss of these systems materially reduces vehicle safety and places occupants and other road users at increased risk. A safety system that can fail entirely and unexpectedly—absent any triggering event—indicates a potential systemic defect, not routine maintenance or wear. I am concerned this issue may affect other Honda vehicles equipped with Honda sensing and may be related to a common failure in cameras, radar units, software, or vehicle electronics. I respectfully request that NHTSA review and log this complaint, investigate this failure pattern, and determine whether a defect investigation, service bulletin, or recall is warranted in the interest of public safety. Vehicle details: make: Honda model: Odyssey model year: 2020 mileage: 87000 VIN: [xxx] thank you for your attention to this serious safety matter. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The front-facing camera stopped working, and all associated adas systems no longer functioned (adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning, lane keeping assistance). Several errors needed to be cleared every time the vehicle was started. Our Honda dealership determined that it was a failed multipurpose camera (code u3000-49), and that the entire camera unit needed to be replaced and re-calibrated.
