2013 Chevrolet Suburban Owner Comments

problem #1

May 222015


  • 32,000 miles


Traveling in the right lane of a four lane highway. Maneuvered into the left lane and accelerated under full throttle to pass another vehicle. After moving back into the right hand lane and releasing the accelerator pedal the vehicle continued to accelerate. Depressed accelerator pedal several times through its full range of motion to ensure that it was operating freely but that resulted in no change. Vehicle did not respond to accelerator pedal input changed. Seemed to be stuck at wide open throttle. Applied full brake pressure as hard as possible to slow vehicle as it continued to try to accelerate. Brakes began to get hot and brake fade was imminent. Shifted transmission selector up into the neutral position. Engine momentarily overran to the rev limiter and then settled at 4000 RPM. Continued to apply brakes to a stop while in neutral. After being stopped for approximately 30 seconds the engine slowed to normal idle speed. Throttle seemed to actuate normally again. Shifted transmission to drive and proceeded to the dealer. Approximately 30 seconds later the dash indicator "grade braking on" appeared in the mfd and then disappeared. I was traveling on flat ground at approx. 20 mph and not depressing the brake pedal. I confirmed that the tow/haul mode was not selected on the transmission. Proceeded to dealership and awaiting repair notes.
