2024 Honda HR-V: false forward collision warnings

Filed Sep 7, 2026 · Brakes, Driver assistance · MA

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.

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

I have brought the vehicle into the dealership multiple times due to dangerous behavior involving the Honda Sensing system. The vehicle has attempted to steer out of lanes, and shown repeated safety warnings related to the Collision Mitigation Braking System (CMBS), Lane Departure Warning (LDW), and Road Departure Mitigation (RDM). Despite these serious issues, the dealership repeatedly tells me that “no codes were found” and refuses to provide full diagnostic records or confirmation that proper factory scan tools (HDS/i-HDS) were used. I suspect they may be clearing codes or failing to document the issues appropriately. The problem is intermittent but dangerous, and I am very concerned it may lead to a crash or serious injury. Honda has not resolved this, and I believe this is a widespread safety defect that deserves further investigation. Most recently, while driving on the highway, the vehicle suddenly applied the brakes without any obstacle or warning, creating a highly dangerous situation. This incident was alarming and could have resulted in a serious accident. Since that event, the vehicle has continued, from time to time, to display warning messages related to the Collision Mitigation Braking System (CMBS) and Road Departure Mitigation (RDM). These alerts occur sporadically and do not appear to be triggered by any identifiable driving condition. The dealership does not want to look at the car again for this problem and is trying to tell me I have to deal with Honda directly who is not escalating the issue even after multiple request as I fear for my safety and that of anyone in the vicinity of the vehicle.

Vehicle has been brought to dealership multiple times due to messages coming up on dashboard stating road departure mitigation system problem. See your dealer and Collision mitigation breaking system problem. See your dealer. Each time the car has been taken in the dealership has stated that the problem cannot be duplicated or replicated and no error codes found. Vehicle is operating as manufactured. Detailed have been requested. On one occasion the dealership stated the vehicle would be needed for multiple days but tried to return it the next day. After calls were ignored for days for answer the vehicle was returned covered in ice and windshield wipers not in the proper position. There is believed to be minor damage in the drivers side wiper. After the message came up again the dealership has stated they have exhausted all attempts to diagnose issue and will no longer work on the vehicle. Multiple attempts been made to gain American Honda's participation but they have not proactively participated. The car has also attempted to leave the lane/road on to occasions. This seems connected to the Honda Sensing probe the federal safety agency has expanded to include 2020-2022 Honda CR-V and Accord. This message was received yesterday and today upon start up and putting the car into gear.

For the second time, while driving normally, with no obstructions in my lane ahead of me, my car’s collision mitigation system abruptly and harshly hit my brakes while warning sounds deployed. This was enough to cause me and my passenger to leap forward in our seats; thankfully we were wearing our seatbelts. I have not been to the dealership yet for this issue, but will tell them at my first oil change. I’m really angry because the jolt this faulty sustem gave us was enough to trigger a panic attack or even a heart attack.
