general problems of the 2001 Oldsmobile Alero

I have been having problems with the engine idling high while driving, making it possible to slow down, brakes were not working, causing me to pull over to the emergency lane, putting the car in neutral, shutting my engine off, in order to get car to stop. My car has been in the dealer shop where I bought it, since July 21, 2005, they said they can't find anything wrong with it, car is still under warranty, but due to not finding anything wrong with the car, they are charging me for towing fee and for doing a preferment check on the engine, out of pocket is over $100. 00 to say, we can't find anything wrong. This wasn't the first time, on June 13, 2005 the same thing happen, putting it in the grange for 4 days only to say they couldn't find a thing wrong with it, I feel there is defect in the computer or idle control, as I feel this vehicle is very unsafe while driving it, not only for myself but for anyone else to be around when this occurs again.

The contact states that vehicle accelerates by itself even when press the brakes. Vehicle will not stop, it still accelerates. The gm repair shop told her three times they cannot find anything wrong with the vehicle, they have the vehicle now.

Problems with high engine idles and shifting through all the gears. This would occasionally occur when the vehicle was started from a cold engine. The transmission was shifted into drive and without the consumers foot on the gas pedal, the vehicle shifted through all the gears. The engine displayed a loud rumble sound. When the consumers foot was taken off of the accelerator it shifted forward. A connector was replaced which appeared to be the problem. The symptoms later appeared. A broken wire was replaced in the harness connector.

Vehicle accelerates on its own, will not respond to braking. It will accelerate for 5-7 miles before it slows down. This has happened 5 times, dealer could not find cause. Vehicle at dealership at this time.
