“I was about to park at a burger king store at delano california 93215 and slowing down when my Scion IA speed up more and kept on running while my foot is already on the brake. So I accidentally hit the store. It only stop because the tire where already up. I tried to reverse my car but cannot move anymore.”

“Second time this happened...first they said battery...while driving, indicating warning lights on dash start blinking (ABS, check engine, traction, and others), then the engine goes into low hear and stays until the vehicle is turned off and back on. During these episodes the speed odometer is erratic. Also when in this state, the reverse gear does not engage. When this started it was a once a month problem, then weekly, now it happens daily/hourly. It started at approximately 40,000 miles. …”
