2023 Honda CR-V FORWARD COLLISION AVOIDANCE

The millimeter wave radar has failed. While using adaptive cruise control the vehicle set off many alarms without prior warning. The vehicle suddenly showed that adaptive cruise control, lane keeping, road departure mitigation, frontal collision, low speed parking were no longer functioning and to see a dealer. I was not using frontal collision no road departure mitigation as these features had twice before unexpectedly applied heavy breaking without warning with no obstructions near vehicle. Fortunately no accident occurred but very unnerving to say the least. The dealer has confirmed that the millimeter wave radar has failed and will need replaced. Honda sensing is not very reliable and should be used with caution if used at all

On several occasions the automatic emergency braking system on my vehicle has engaged for no reason. The vehicle applies the brake quickly with nothing in front or to the side of the vehicle. This sudden braking has almost caused me to be rear ended and has also caused a slight case of whiplash. I’ve contacted my Honda dealer and while they say they’ve had complaints I am told there’s nothing in the works to remedy the issue. I was told to clean my vehicle front sensors (which were not dirty at the time of these instances) and that’s all I could do. This has happened multiple times throughout my ownership of this vehicle with the last incident occurring in late September of this year.

While driving my vehicle in snowy conditions, my vehicle slammed on the brakes and sensed a collision. The sensors were covered with snow, and typically, the sensors will turn off when they are obstructed. At the time I was going 30-35 MPH in 1-2 inches of snow and my vehicle detected a possible collision and auto-braked, bringing me to an immediate stop. Should there have been a vehicle immediately behind me, I would have been rear-ended and the vehicle behind me would not have had time to react due to the snow conditions. I cannot stress how dangerous this is while driving in adverse conditions with other vehicles around you to have your vehicle come to an immediate stop. This continued to happen 4 more times at while driving at lower speeds, during turns, driving in parking lots. Each time the system will state something related to forward collision avoidance and the giant "BRAKE" sign will flash in my dashboard. I no longer felt safe driving my vehicle in the snow due to this auto-braking system.

While driving in cruise control on two lane roads, vehicle will brake hard during curves and going up rolling hill sections even if there are no vehicles or obstructions ahead. This vehicle experienced an overheated camera system at 4500 miles and was in the shop for 3 months for repair. The above described condition occurred before complete camera failure made all safety features not function. So it could be a camera failure is beginning again, or there is an inherent defect in camera or software that powers the braking.

On January 19, 2024 my wife was driving the CRV when it suddenly slammed on the brakes bringing the car to a full stop. The dashboard screen said Object Detected. It was a violent stop, so much so that she thought she had been rear-ended. Luckily, she was not going very fast and the car behind her was able to stop without hitting her. If it had happened at a higher speed on a busier road she and others could have been injured or killed in a crash. She called me crying and upset and could not get off the road because the problem repeated four or five more times. We had the dealership come pick up the car and they found code "P2583-54" for the radar system aiming incomplete stored in the car. They performed a static and dynamic re-aiming of the radar and said it was ok. We felt the vehicle was unsafe and entered into arbitration with NCDS. The manufacturer never explained what the cause of the radar malfunction was (such as faulty hardware, rushed manufacturing, etc) and expressly stated that they could NOT guarantee the problem would not happen again. There had been snow and ice present on that day. The sensors had problems (different alarms and sounds but no phantom braking) again on Feb. 16th. These dates are the only two significant snowfall days we have had since purchasing the vehicle. We feel the vehicle is unsafe in any amount of snow or ice and think an investigation should occur into the radar system so that a recall can be issued so that nobody gets hurt or killed. Thank you.

What component or system failed or malfunctioned, and is it available for inspection upon request? - The adaptive cruise control and emergency braking. How was your safety or the safety of others put at risk? - The system is reading that other cars on my passenger side usually or coming on or off the exit ramps on the interstate as cars in front of me. In turn the system directs the car to slow down and then at some points break hard while driving at highway speeds. Has the problem been reproduced or confirmed by a dealer or independent service center? - The technician at the Honda dealer told me just to turn it off as its better to have it off than on. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - There has not been an accident as of current that would warrant an inspection. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - The adaptive showing the car in front, showing the word BRAKE on the mini dash and then you can also feel the gradual to almost complete stop of the car when this occurs. The main place to see is the outline will fill up as if a car is in front, but one is not.

While driving on a clear day on a relatively flat straight road the CMBS activated and applied the brakes abruptly. There we no objects in the road when the brake light appeared and the car abruptly applied the brakes. There were no apparent conditions that would warrant this action. This issue has only occurred once and the dealer has not yet inspected the car since this incident.

As I was driving down the street at 45mph, with no one anywhere close in front of me, the warning brake noise and lights came on and the car quickly braked and brought the car to a stop. Thankfully the person behind me was not following too close, but it sure shook me up!

I was driving on a rainy day about 10 am. I was driving about 35 mph when the car suddenly braked for several seconds for no apparent reason. Then everything went back to normal driving. This could of caused an accident had somone been driving close behind me.

Vehicle began hard braking using the collision avoidance system when there were no other vehicles or obstacles on the road. Then the vehicle safety systems (adaptive cruise control, lane keeping assist, collision mitigation braking system and road departure mitigation system and brake system) all began displaying warning messages. The car only has 1600 miles. The dealer inspected and states that the safety systems are not functioning because the camera failed. A replacement part will not be available for six weeks and the dealer indicated the vehicle was safe to drive with the error messages, but that in an accident none of the safety features would function. The dealer is unable to provide a reason for the failure, but suggested it could be due to heat. The dealer indicated there was the same vehicle type that experienced the same failure a few days earlier.

The Automatic Emergency Braking abruptly stopped while traveling 50 mph without any obstructions in front of me almost causing a rear end collision from the car behind me. In addition the stop caused minor whiplash.
