“Jan. 23, 2020. 10:45 am. I was on my street, a narrow residential street, preparing to back in my garage. In order to do that on this narrow street, I touched the lip of the driveway across the street. Speed well under 3 MPH. When I did so, my car suddenly sharply accelerated and at the same time swerved to the right. The acceleration and swerve drove the car into the townhouses across the street from my house.

My car is 3 years old and only has approximately 67,000 miles on the engine. The fuel injectors were replaced at 10,000 miles by warranty. …”

“From a full stop and foot on the brake pedal, move foot to hit the gas pedal and a delay or lag is experienced about 50% or more of the time. The regional Mazda expert and dealership have verified the problem and nothing but excuses why they cannot figure out how to fix it have been stated, therefore I have been living with it for over 20k miles on a new car.
