5 seconds after starting the vehicle it suddenly went into unintended acceleration from 5mph to about 40 MPH. I immediately applied the brakes but the car would not slow down or stop. I then shifted into neutral which did nothing, then shifted into park, which did nothing. Still applying the brakes I tried numerous times to shut (push botton) ignition off but that was unresponsive. I hit a street sign which slowed me down and the car finally came to a stop but the engine was still reving loudly for another solid minute. I again was pushing the ignition button and the car then suddenly turned off.

While driving at 50mph my vehicle suddenly slowed down to 5mph. Luckily for me no cars were behind me when this happened because I'm pretty sure I would have been rear-ended. Soon after this happened I looked at my dash board to see if any warning lights were on but there was nothing. So then I continued to drive to a side street all whilst pressing the accelerator with no response. Once I turned on to a side street an attempted to pull over the vehicle suddenly accelerated, which I was not expecting to happen. At this point I had to slam on my brakes and placed it on park. After getting over the fear of driving my vehicle I was able to drive it home, but not without having my vehicle dramatically slow down again while driving up my driveway.

Out of the blue, I started my vehicle to go to work and the check engine light was on. I read in the manual the gas lid could be loose, but I checked it and it was fine. My husband took it to the dealership and they hooked it up to see what the problem was, and they said it was a miss in the engine, and he'd have to leave it with them so their tech team to try and get to the root of the problem. I had felt hesitations before while coming up our driveway, which is pretty steep. It's like it would almost stop then lunge forward pretty quick. It also has felt like it wasn't changing gears at times, like it normally would. This just happened randomly.

While changing lanes on highway from a stop, it felt as though the car was in neutral instead of drive. The RPM increased but the car did not move. I have also noticed upon sudden acceleration from around 30 that I get a similar response. Mazda states vehicle performing as by design. Car does not seem to down shift quick enough on acceleration.

While the brake is held down with the left foot and a slight pressure is put on the gas pedal the car will suddenly surge forward. It can move about two feet before I get the brake on hard enough to stop the car. It feels as if the vehicle was struck hard from behind. The dealer has looked at it twice and suggested that the bog for "break over gas" logic system is being fooled by the combined pressure on the brake and gas at the same time, I.e., if, while both pedals are pressed, if the brake pressure is slightly released while the gas pedal is still slightly depressed the computer thinks the it has to "catch-up with the gas pedal and it surges forward. It has happened five times. It has never happened without both the brake and gas being simultaneously applied. It becomes a safety issue when it happens at a busy stop signed intersection while waiting to make a left turn across oncoming traffic, I.e., a pedestrian could be struck. I try to avoid this using this technique but it is a habit that I'm sure many drivers have.
