Our 2015 Acura MDX has been at the dealership 8 times. Our vehicle has been out of service for approximately 64 days total. It has been at the dealer for electrical glitches starting with seats, steering wheel, gps and for rautomatic braking issues. Steering wheel and power seats repeatedly not setting to appropriate key fob settings. Car has been to dealer for this issue 4 times. Dealer unable to reproduce issue or show "trouble codes" until 4th time in shop. The next glitch moved into the gps system and controls on gps screen. The screen remained bright at night. The controls disappeared from screen. This was video recorded. The dealer stated this must have been a glitch. The dealer stated unable to reproduce the glitch. The dealer stated no "trouble code" detected although it was clearly video recorded with date. The vehicle locked the brakes up while in operation with no vehicle in front. The operator was nearly in a rear end collision had the driver behind not been following at a safe distance. On the next occasion, while at a red light stopped, the "brake" warning came on. This warning is designed to come on when in motion. Operator was concerned if the vehicle had been in motion again it could have caused the vehicle to brake suddenly. These incidences could have caused serious injury or death. The dealership simply stated they could not reproduce the event and stated the vehicle was operating as designed. Owner sent recall articles as it related to braking issue but was informed vehicle did not fall under recall. Owner is simply illustrating with detailed notes and videos that the vehicle has electronic issues that vary and ultimately have turned into safety concerns. Owner wanted "safety concern" to be documented in work order but dealer did not document this as such. Requested dealer put us in a safe car of equal value. They refused.

I was driving in houston, going North on kirby drive, which is a busy city street, at approximately 4:30 pm on Monday, Oct. 26, 2015. Shortly before I reached the intersection of kirby dr. And sunset blvd, I approached a standard sized steel sheet/plate in the road. The brake alert flashed on my dashboard. I ignored the alert and continued to drive, because my car was not in danger of hitting anything. As I got closer to the steel plate, the vehicle's collision mitigation braking system applied the brakes on its own, I assume because it perceived the steel plate to be a collision threat. I had no control over my SUV, and there was nothing I could do to resume normal acceleration. The collision mitigation braking system only disengaged once the SUV was directly on top of the steel plate. My children and I narrowly avoided a rear-end collision. At the time, because the city street was so busy, I was only traveling 20-25 mph, as were the other cars around me. I fear what would have happened at higher speeds. Many houston roads, including our busy highways, have steel plates covering road repair projects. I am afraid the brakes will engage spontaneously on the highway. When I called my dealership shortly after the incident occurred, I was informed that unless there is an active signal on my car showing the need for some kind of service, the dealership won't be able to fix or identify the problem. Supposedly, my vehicle was subject to the May 20, 2015 forward collision avoidance recall involving the 2015 Acura MDX collision mitigation braking system (NHTSA campaign #15V301000). The dealership said that it addressed the recall issue as a part of my August 2015 checkup, and that as a result, my vehicle met all standards. I note that my complaint is not the only one pertaining to this issue (see NHTSA id #10763775). The recall fix may not have worked.

After the recall of collison migration braking system (cmbs). With the new recall software. The MDX stops or apply the braking on the freeway. This is a continues to this day. The dealership had the vehicle for about one week. They said that it could not find a problem. The dealership put over 250 miles on the vehicle. I still have the problem of the braking system appling the brakes going from concreate to asphalt with speeds over 50 miles per hour. I have to react to each braking quickly. It also happens if their is a small bump in the road like a very small speed bump. Sometimes over the same area I would get the braking alert flashing on the heads up display. Sometimes the braking light happens with seat belt jerking back and a change of speed. Only once since I got my vehicle back from the dealership did it do a full braking. And there was no other cars in front of me just the road. I am lucky to have no one behind me when this happens.

Upon entering a T-intersection with a stop sign at the end of our street the brakes of a 2015 Acura MDX sh AWD with only 2000 miles would not engage. We were traveling at 50mph and decreased our speed to 30mph as we were coasting, but could not get the vehicle to stop. The brakes were pumped twice as we decelerated (so rest assured the gas pedal was not being pressed by mistake), but to no avail and with no where to go and not enough time to do much more we collided with a semi truck. It was a horrific accident that totaled our car as the second trailer tires ran over our hood as he was driving at 60mph. Luckily due to his high speed our vehicle was thrown and we landed upright and all airbags deployed which is the only reason we are all alive. It was a cold December morning with below zero temperatures. I understand there are other accounts where brake pedals are not working in the cold or where drivers are pumping brakes 4-5 times to get them to engage, or drivers are turning their car off. We sadly did not have that kind of reaction time. This could have resulted in 4 deaths and I would like to see Acura look into their plethora of brake problems further as this is a brand new vehicle coming off of a brake redesign due to the earlier model recall.
