I own a 2024 Honda HR-V. Since I purchased the vehicle, I have experienced recurring warning messages stating: "Collision Mitigation Braking System Problem - See Your Dealer" and "Road Departure Mitigation System Problem - See Your Dealer." I brought the vehicle to the Honda dealer and reported these problems. The dealer scanned the vehicle and told me that no fault codes were found. Despite this, the problem has continued. On one occasion, while driving at approximately 5 mph, the vehicle unexpectedly applied the brakes on its own. There was no vehicle, pedestrian, cone, rock, debris, or other obstacle in front of the vehicle. I did not intentionally apply the brakes to cause the sudden stop. I am concerned that the Collision Mitigation Braking System or another Honda Sensing safety system may be incorrectly detecting an obstacle and applying the brake hen there is nothing in front of the vehicle. This is a safety concern, it could save lives and stop accidents from happening if this safety issue gets investigated and find a solution.

What owners say
The Multipurpose Camera Unit/Millimeter Wave Radar Internal Electronic system has failed (confirmed by Honda service center). When I start my car, I now get several warnings that multiple systems are out, including but not limited to the automatic emergency breaking, forward collision warning, and many other safety features. Upon searching the web, it seems this is a common issue in many Honda vehicles starting in 2018. With this feature no longer working, I have no back up safety mechanisms, which is one of the main reasons I bought this car.
The 2019 Honda HRV with low miles of around 44,000 miles experienced a series of warning alerts on the dash board consisting of the following list of five problems: Road Departure Mitigation System Problem; Auto High-Beam Problem; Adaptive Cruise Control Problem ACC; Lane Keeping Assist Problem LKAS; and Collision Mitigation System Problem. This started with warm weather at the end of July 2026 and is continuing intermittently in August 2026 as of the date of this write up. I described this to a Honda service person verbally in person in Huntington Beach, CA and they said it was a Multipurpose Camera problem and could fix it for $1,971.23 plus tax. They indicated that the camera was improved so it wouldn't fail so easily. The vehicle has not been physically inspected by dealer service staff yet. With all these safety features potetially not functiing at times creates great safety risk (e.g., Adaptive Cruise Control is not really on when you think it is and the car could rear end another vehicle in front especially if the Collision Mitigation Sytem is also malfunctioning). Car with low miles and in great shape otherwise. No significant accidents. No cracked or replaced windshield. Have a large 113MB video if needed of dashboard problem warnings.
The Multipurpose camera has internal failure and the unit is running at 130 degrees per diagnostic tests per mechanic. It's affecting the lane keep assist, automatic high beams, road departure, mitigation, adaptive, cruise control, collision mitigation system. These safety features are not working.
Lane keeping, adaptive cruise control, auto high beam lights, forward collision warning. It is available for inspection. This is the whole reason we went with this car was the safety features. Now none of the forward Saftey features are currently working because of the front safety camera failure. Have not returned to dealer since it is out of warranty now. No warning lamps before this problem started.
While driving my 2022 Honda HR-V, multiple Honda Sensing warning messages appeared simultaneously, including front camera system errors. Features such as Collision Mitigation Braking System, Lane Keeping Assist, Road Departure Mitigation, and Adaptive Cruise Control became unavailable. The warnings affect important safety systems and also create a distraction while driving. This appears to be the same front camera defect that many other Honda owners have reported.
Components of concern: collision mitigation braking system - while driving with no car in front of vehicle, car slammed on brakes - could have caused an accident. Yes, available for inspection. Also, lights went off and said to see dealer (have picture that I'm having issues attaching). Lights that went off were : collision mitigation braking system, road departure mitigation system, auto high beam, adaptive cruise control, some driver assist systems cannot operate (clear front windshield or poor viewing distraction) - all at the same time, even when it's no visible windshield issues. Yes, available for inspection. Want to take to Honda dealership but I'm being charged $80 for a diagnostic when this is a system issue. Not yet
Driving on the highway then all of a sudden the display lights come on, forward collision warning, driver assist, headlight,lane assist and brake light comes on. Pulled over and started the vehicle but still no change. Took to dealer,found faulty camera
The forward camera mounted on the windshield failed which means all of the advanced safety features will not work that is a safety hazard when you rely on these systems. Looking on the internet, this seems to be a common problem and is very expensive to fix. There are multiple warning lamps that appear. They are Brake System, Auto High-Beam Problem, Collision Mitigation System Problem, Lane Keeping Assist Problem, Road Departure Mitigation System Problem, & Adaptive Cruise Control Problem. I don't understand how there are recalls when the rear camera does not work but not the front camera. They are both safety features.
Since purchasing my 2022 Honda HR-V in 2024, I have experienced ongoing unintended or “phantom” braking while driving at highway speeds with adaptive cruise control, lane keeping assist, and the Collision Mitigation Braking System activated. When a vehicle is traveling in an adjacent lane—most frequently on the right side—the dashboard displays an orange brake warning, and the vehicle abruptly brakes without driver input despite no obstruction in my lane. This issue occurs approximately four times per week, and the vehicle currently has about 75,000 miles. During each incident, I disengage adaptive cruise control using the steering wheel controls to regain manual control. Although no accidents or injuries have occurred, these sudden braking events have resulted in multiple near-miss situations and present a significant safety concern.
