While leaving work I accelerated to pass a vehicle, vehicle would not decelerate, speed climbed to 115mph on a two lane road within city limits. I placed both feet on brake pedal and pushed it to the floor. Vehicle continued to accelerate with intersection fast approaching (1 mile), Tried to engage cruise control button to fool the computer. Placed gear selector in second, then first, still accelerating. Trying to decide where to have my controlled rollover, still pressing on brakes and pushing ever button I could. Finally, accelerator disengages. All 4 rotors are tinted blue, don't know how the pads didn't fade. Vehicle drove home fine, brakes worked fine. Has anybody experienced this?
