Driver Assist & Collision Avoidance complaints by model year
The forward-facing Honda Sensing camera mounted behind the windshield (Nidec monocular camera, Honda part number 36160-TRW-A04) failed at approximately 85000 miles on XXX The failure produced simultaneous dashboard warnings and disabled multiple driver assistance systems at once, including Collision Mitigation Braking System (automatic emergency braking), Forward Collision Warning, Road Departure Mitigation, Lane Keeping Assist, and Adaptive Cruise Control. There was no impact, no windshield damage, and no obstruction of the camera lens. The failure appears to be internal to the camera assembly and occurred without warning during normal driving. Because all of these safety systems depend on this single camera, one component failure removed every forward collision protection on the vehicle simultaneously. The sudden appearance of multiple warning lights at once was also distracting while driving. The vehicle is out of warranty and Honda has offered no repair assistance. Dealer replacement is quoted at approximately $1,500 to $2,000 including required camera calibration. This same camera failure is widely reported by owners of Honda Sensing equipped vehicles, including Clarity, Odyssey, Pilot, Civic, and HR-V models, typically at [XXX] to [XXX] of age, which suggests a durability or thermal defect in the camera assembly rather than an isolated failure.

It looks like this is possibly at this point a wide spread issue with most if not it will be all honda clarity models. The lane departure warnings, adaptive cruise control, front camera honda sense electronics keep to go out and then will work for a little bit. sometimes just not work at all for months, then work for like a day or two. After reading many of many complaints about this it will seems to be pretty much widespread across all yearly models.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
To Whom It May Concern, I am the owner of a 2018 Honda Clarity, and I am submitting this complaint to request that the National Highway Traffic Safety Administration (NHTSA) investigate what appears to be a widespread defect involving the front camera system used by Honda Sensing. My vehicle has experienced a failure of the front camera system, which has disabled numerous critical safety features, including: • Adaptive Cruise Control (ACC) • Automatic Emergency Braking (Collision Mitigation Braking System) • Blind Spot Warning • Forward Collision Warning • Lane Departure Warning • Lane Keeping Assist System (LKAS) • Parking Collision Warning • Rear Cross Traffic Warning When the front camera fails, these safety systems become unavailable, significantly reducing the vehicle's ability to assist the driver in avoiding collisions and maintaining safe operation. After researching this issue online, I discovered that thousands of Honda owners have reported similar failures involving Honda Sensing cameras and related driver-assistance systems. Many owners have reported receiving warning messages, loss of safety functions, and repair estimates costing thousands of dollars. This appears to be a recurring problem rather than isolated incidents. I believe this defect presents a serious safety concern because drivers may unexpectedly lose access to critical collision avoidance and lane safety technologies that were included as standard safety equipment on the vehicle. The failure of a single camera component should not disable so many essential safety systems without a more robust fail-safe solution. I respectfully request that NHTSA investigate this issue and determine whether a safety recall or other corrective action is warranted for affected Honda vehicles, including the 2018 Honda Clarity. Thank you for your time and attention to this matter. I would be happy to provide additional information, repair records, photographs, diagnostic reports, or any other documentat

NHTSA complaint #11743727 — an unverified report by a vehicle owner.
Here is an update to the issue I had raised with your office in March-April 2026: Honda Van Nuys performed the 35,000-mile routine maintenance on the Honda Clarity on February 24, 2026. At that time, Honda Van Nuys recommended (and I approved) that they clean the throttle. The odometer read 33,882 miles. I drove the car 337 miles when the unintended acceleration accident occurred on March 18, 2026 – 2.5 weeks after Honda Van Nuys cleaned the throttle. The airbags deployed. The throttle seems to be the part that failed based on the attached EDR report. The odometer read 34,219 at that time. The car is now considered totaled by GEICO. In addition, Honda Van Nuys has done all maintenance work on the Honda Clarity, including some major removal of the dashboard and back seats, since I purchased the car there in 2018, as outlined in the attachment. I have reached out to Honda Van Nuys and hope your office can encourage them to respond. This is a safety issue. The attachment elaborates further.

NHTSA complaint #11742767 — an unverified report by a vehicle owner.
The forward-facing multipurpose camera unit (ADAS camera) failed internally while driving, causing the simultaneous deactivation of multiple critical safety systems including Collision Mitigation Braking (CMBS), Road Departure Mitigation, and Lane Keeping Assist (LKAS). The failure is indicated by persistent dashboard warning messages stating 'System Fault' or 'Honda Sensing Problem'.A professional diagnostic scan confirmed DTC code U3000-49 (Multipurpose Camera Unit Internal Failure). The sudden and unpredictable loss of these automated safety features reduces the vehicle's ability to assist in avoiding collisions and increases the risk of a crash, particularly in emergency situations. This appears to be a widespread manufacturing defect in the camera hardware that poses an unreasonable safety risk to drivers and passengers.

I was just driving normal and a message on my dashboard started to appear saying to clean my windshield or the collision mitigation system cannot work, We cleaned the windshield several times and it didn’t work the light still on, mow it got worst all of the lights turned on when I drive the car, adaptive cruise control light, road departure mitigation system problem light, lane keeping assistance problem light, collision mitigation system problem light and Brake system light, I checked online and there’s alot of people complaining from the same thing, they said it’s an issue with the front windshield camera but honda wants to charge thousands of dollars to fix it and there’s other honda models with the same problem too. I don’t know if it’s safe to drive it or if more lights are going to come up.

I had an unintended acceleration happen as I was easing into a parking spot of a covered parking garage. The car accelerated like a jet plane taking off. I jammed on the brake. The only thing that stopped the car was the concrete wall that was 4 feet away. My airbags activated. We had taken the car to the Honda dealer for its 35,000-mile check-up on February 24, 2026. The Honda dealer has prepared all maintenance, including Honda recalls, since we bought the car in 2018. I'm scared about what caused the unintended acceleration and concerned that others could be injured. Electronic throttle control? Cruise control? Sensors? Wiring problems? What activated it? I believe this is a Honda mechanical problem. I have researched online that others have had unintended acceleration problems with the Honda Clarity and CRV–another plug-in hybrid–but not enough claims to lead to a recall. I have gotten a runaround. Our insurance carrier has declared the car a total loss but refuses to have the computer assessed to determine the cause. The local Honda dealer says it’s not their problem, claiming that we would have to tow the car to them and pay them to replace all safety items. They would then reboot the computer and delete all data, so they could not assess the cause. They said the Clarity has no “black box.” I contacted American Honda Corporation's customer service. Their engineers would not look at the car either unless our insurance company asked and paid them to do it. I have that Case Number. You would think that American Honda Corporation would be concerned, particularly since this unintended acceleration could have killed pedestrians if it had happened on the street or killed me if the concrete wall had not stopped the car. We had the Honda Clarity towed to our house to see if we could find someone to check out the computer. The towing company has driven the car, even though the airbags were activated. After 30 days, our insurance company will take the car for salvage.
