Made a slow right turn into a parking place to pick up my dogs at the groomer, when I applied brakes to stop, the car accelerated lurching forward. I then took my foot off the brake and reapplied instead of slowing down the car sped up and was only stopped when I hit a brick building. I had two dash warnings "front camera sensor system malfunction" and "forward Smart city bread support malfunction" I am not certain how fast the car was moving when I hit the building but the entire front of the car is significantly damaged. Further the air bags did not deploy. I have photos of both the collision damage and the warning lights. The dealership requested they run diagnostics and found nothing wrong claiming the accident was my fault as I must have put my foot on both the brake and gas at the same time. I am an experienced driver and this was not the case. The also stated the warning lights were a result of the accident not the cause. I am only grateful I was not pulling into a space closer to the door as I would have gone through a plate glass window and most likely would have cause a serious injury to anyone standing in the lobby.
While light braking, car brakes jam. . . Causing unintended stop. Dangerous. At no time was a code flagged. Mentioned to girl at desk when in for service 3 times. When car when in for service. Ladt service I believe car was put on diagnostics. Was told nothing found. Because it happens so often, & dealership tells me cannot find any problem. . . I called a mechanic outside of Mazda. Spoke on phone with master mechanic. & described problem. . He informed me problem was a sensor in the transmission. Car shuts down & locks. Because it happens so fast no code is generated. Said is serious problem.

Slow speed, 15mph, normal braking in congested highway traffic, going straight, anti lock brake system activated and vehicle automatically braked very hard, vehicle behind struck our car from behind because they did not anticipate a very hard brake, conditions did not call for a hard brake.

Very dangerous malfunction. Will be bringing to dealership today , 12/27/2018. State troopers at scene and report filed, not yet on hand for submission.
