The automatic brake mitigation system has deployed on 3 separate occasions for no apparent reason. Each time I was driving on a clear road with no obstructions or traffic in front of my vehicle when the system activated and began braking. This has not let to an accident yet but I think it is an obvious safety hazard because it could cause a driver following behind me to "rear - end" me or it could cause me to have a single car accident in my own car by un-necessarily braking on a roadway compromised by rain, snow or ice when I was not prepared or unable to manage a braking episode. I have reported this to the dealer but the problem is obviously very intermittent and they could not reproduce it nor diagnose it. I feel this is a clear safety issue on a primary safety system..

Collision mitigation breaking system engages randomly when not necessary. Seems to be heat related as it occurs during very hot weather. A sudden stop is jarring and could be dangerous.

My car had 9100 on Rdx I needed to have my pads and rotor replaced on from brakes. I had problems with brakes at 5000 miles. When I pick up car I heard noice when pumping breaks when I was picking up vehicle and mechanic could not find anything wrong. I have talk to Acura customer service which were not helpful. I spoke to jim brown GM at ron tonkin. He stated he would talk to his manager of repairs and Acura rep about car. I have already had the radio and board replaced. Lane keep assist warning light come on 2 times and reset my software reset. The microphone replaced. I have had terrible case mile I have never gone above 19.6 mpg per gas tank refill. Darrel said that is epa suggestion. My navigation keeps alarming 4 blocks away from my home. Siri does not work properly. I will tell it to call someone sometimes it does sometimes it doesnt even with new microphone. I have had the car in the shop 4 times close to 4 weeks. I have a lemon and would never tell anyone to by an Acura.

June 18, 2016, I had a service appointment for a road trip special. I was going on a road trip a few days later. I advised [xxx] my steering wheel is shaking a little when breaking from higher speeds. When I got my car back, [xxx] stated they replaced the front rotors and pads. About 2 weeks later, I began hearing a noise sounded like a little grind. Kept driving didn't hear it again. As I went about my day, time and time again I would hear this small grind. Some days would go by and I would hear nothing, then suddenly as I am driving I would hear it again. I have taken the car back and advised I am hearing what appears to be a grinding noise. In July I told them I was going on a road trip and wanted my brakes checked because I am still hearing this noise. When I picked up my car they did not hear anything. I told them if I hear any noises on my trip I was going to be pissed. My brakes were grinding while I was on my trip. I called the dealership left [xxx] a voicemail he did not return my call. I didn't think then to record it. I made a service appointment for Aug 2, nothing came of it. I took the car in, took the tech on a ride and of course could not get the car to make the grinding noise. As a result, [xxx] told me, [xxx], we already changed the pads and rotors, if we cannot hear the noise we cannot fix it, when it makes the noise to bring it back. I was pissed. Not satisfied, I contacted the service department again spoke to the service manager [xxx], he offered that he would take my car and drive it to see if he could hear the noise. Aug 10 he stated he did not hear the noise. I told him there is clearly a problem, and someone needs to address it, take the car apart and look at the breaking mechanism. He told me that they cannot just throw parts on the car hoping it would fix the problem, they need to hear the noise in order to fix it.

I had 5000 miles on car and my brakes started making noise like the pads needed replacement. I was coming to a light and putting my brakes on and also driving on highway I was slowing down and heard the noise. Took my car to dealer and they stated this can happen if you are on the hills in portland. I explain that I do not live in the hills. They resurface rotors but I am concern there is something else is going on.
