Cpm malfunctioned causing the throttle to become stuck in full open position. the vehicle was continued to accelerate and would not stop. computer was stuck in 100% mode. brakes including the emergency brake would not stop the vehicle. tahoe continued to gain speed. rpm's running between 500-600 rpm. traffic was everywhere turning onto a 2 lane side road and notifying 911 i put the car in neutral and turned the engine off. the vehicle coasted for another mile or more before stopping. the brakes were smoking at that point.
I was passing on a two lane high way at an accelerated speed at which time the engine dies, no lights no nothing total engine failure. luckily i have enough momentum that i safely get around the semi and continue to be able to coast until i find a safe place to pull over. i call my local dealer who will not come tow me as i am approximately 50 miles from home although i do have gm roadside assistance. i turn off the ignition and it does restart so i manage to drive to a nearby dealership and leave it there. nothing shows up on the computer i refuse to take it home. should they not be able to repair this problem i will hold the dealership and general motors 100% responsible. thank god my daughter and i are safe but this is a tragedy waiting to happen if not resolved. *tr
