Unintentional acceleration and failure of collision mitigation system 2014 acura mdx advanced. Accident occurred at a strip mall parking lot located 1 mile from my residence where I was grocery shopping. Weather 65 f sunny. Heavy pedestrian and vehicular traffic. I was parked head in diagonally. I placed my right foot on the brake pedal,placed the SUV in reverse,lifted my right foot from the brake pedal, depressed the accelerator pedal and slowly backed out of the parking space,straightening the wheels in the process.I placed my right foot on the brake, shifted to drive, and placed my right foot on the accelerator pedal and without actually depressing the pedal the engin reved uncontrollably and the SUV surged forward 100 ft at increasing speed before colliding in a domino fashion with a row of 6 vehicles pushing one of the vehicles over one of the adjacent vehicles before veering off to the side and traveling an additional 200 feet before coming to a stop.the drivers side chest and knee bags deployed when I impacted with the first vehicle.I do not remember if I attempted to brake.there were no injuries.the damages to my SUV were extensive. My insurer declared it a total loss.I have photos taken at the scene of the accident showing skid marks and the damages to the vehicles before they were moved. My insurer had my vehicle examined by an automotive technician.he concluded that I simultaneously stepped on the brake and accelerator because of the pedal ware pattern. Also the diagnostic port did not show an error code.he did not examine the event data recorder (black box). I do not agree with his conclusions. I believe I did not step on the pedals simultaneously. In retrospect I believe that I accidentally engaged one of the cruise control buttons located on the steering wheel when I was backing up and straightening the wheels.

Traveling 65 MPH on a freeway with adaptive cruise control (acc) engaged, vehicle suddenly brakes hard on its own for no apparent reason; dropping 10 MPH in a heartbeat. The vehicle did not produce a collision warning message on the dash. The cars in front on me were well beyond the longest 4 bar range of the acc so it was not detecting and locked onto a car in front of me. There were no cars on either side, no car crossing in front of me and the road was flat with no obstacles. Fortunately, the car behind me was not tailgating as the sudden deceleration could have caused a rear end collision. Sudden deceleration has happened twice during the six weeks I've owned this vehicle. I've also noticed that the acc is inconsistent, often sluggish, in responding to the speed of traffic when it is detecting a car in front of me; creating additional hazard concerns for the driver. *tr..updated 05-27-15 *bf updated 8/28/2017

Our vehicle is an acura mdx 2014 with the advance package. One feature of the package is adaptive cruise control which aims to keep the vehicle moving at a steady rate and at a set distance from any vehicle in front of it. On several occasions, when vehicles in front of ours slows down or a vehicle merges from another lane in front of us (even transiently), instead of gradually braking and speeding up, the acura performs sudden deceleration with hard braking even if the vehicle in front is doing the same speed or going only slightly slower. After the hard braking starts, if the vehicle in front speeds up, our vehicle does not recover and start to accelerate again. I have a pregnant wife who is the main driver of the car and I am concerned that this problem will cause her to be rear-ended.
