Twice within one month my Corolla experienced Sudden Unintended Acceleration. The first time I had just entered the parking lot of my local Star Market. I stopped for a man in the crosswalk and was just about to ease off the break when I saw a woman approaching the crosswalk so I stayed on my break. Suddenty the car revved up and went forward. I think it was so loud the woman heard it and stopped. My car returned to normal operation within maybe five seconds and as I drove by the woman, I yelled there was something wrong. Went home and scheduled an appointment with Toyota. It took a few days for them to check my car. I think this type of issue brings in the next level up of repair. I was told they went over everything and could find nothing wrong. My car was safe to drive. I drove it for exactly one month and it did the same thing. This time I was inching my way into a parking space that was up against a wall. Nowhere near the gas. I was maybe a couple of feet from the wall when the car accelerated again. The engine really revved up again and I went into the wall. The car was drivable, and I got it right back to Toyota. It is still sitting there pending investigation. I am waiting to hear from someone from their liability department. I'm not sure what will happen, but I know I will not drive that car again. My biggest concern is that Toyota will claim I'm elderly and hit the gas, not the brake. That is not what happened.
