Owners/service Manual problems of the 2018 Honda CR-V

While driving the vehicle, the "collision mitigation braking system" activated for no apparent reason. Honda owners manual states this has 3 stages of warnings. This particular incident was definitely a stage 3 warning. I was driving at approx. 40-45 mph on a straight stretch of road with the closets vehicle in front of me probably a 1/4 mile ahead. The car all of sudden braked very hard for no reason to the point it actually threw me forward in the seat, almost came to a complete stop, and had a car behind me been closer, they likely would have rear ended me. This is the second such incident I've had with the vehicle and feel it causes a very unsafe condition.

Had backup sensors installed by the dealership, jenkins &wynn; clarksville, TN. The back up sensor beep volume is so low that they are inaudible to myself. My wife can barely hear the beeps. The sensors cannot be heard at all if the vehicle audio is turned up at all. The backup sensors user's information manual does not provide any warning stating the beep volume is extremely low/inaudible to hearing impaired people. Also, the manual also does not state that when the backup sensors are activated, that the audio is neither muted or lowered so the driver can hear the beeps. Drivers may be accustomed to other vehicles back up sensors systems that lower radio volume and have beeps loud enough to be heard by all drivers, including hearing impaired. I believe that on top of the fact that Honda is deceiving customers who are expecting standard backup sensor activity; such as loud/audible beeps or the lowering of the vehicles audio volume when the sensors are activated; there are no warnings in the manual alerting drivers to these non-industry standards. I believe these failures to notify drivers/owners may cause to unsafe conditions during backing that can seriously injure or cause the death of someone during backing.

On December 12, 2017 at about 4:30 pm, the collision mitigation braking system failed and put my car into a panic stop when I was not about to have a collision with the car in front of me. I was driving east along a 4 lane undivided highway in the right lane (slow lane) at about 45 miles per hour approaching a traffic signal that was green. There was a car ahead of me in the slow lane at the signal, slowed down to make a right hand turn. I was 5 or 6 car lengths behind this car and in no danger of colliding with him. Without any warning, my car applied the brakes in a full panic stop. Fortunately there was no vehicle behind me. There was no collision with any other vehicles, but my right hip and lower right back were sore for several weeks. I reported the incident to my insurance company and to the dealer that sold me the car. On the dealer's suggestion, I set the forward collision warning distance to "short"; it had been set at "normal", the factory setting. Most days I manually turn the collision mitigation braking system off before I drive, but on the days I have forgotten, the problem has not re-occurred with the forward collision warning distance set to "short". I believe that if there was a vehicle behind me when the problem happened, he may have collided with the back of my car and caused me further injury. I thought for the safety of others, I should report this problem to you.
