Cruise Control problems of the 2003 Chevrolet Malibu

I was driving my car in town, I went to slow down my 2003 Malibu the car kept speeding up, the throttle would not disengage until I physically lifted up on the underside of the gas pedal. I immediately took it over to have it checked by a certified mechanic and they also experienced the same exact issues only when the car is moving. They put it on their service computer and I was told that no codes came up and the the only way they were able to get the automatic acceleration to stop was to disconnect the cruise control module. The mechanics shop disconnected the cruise control and it has not happened again since that was disconnected however, this was a extremely scary situation because braking doesn't help the car still continues to accelerate & peel out, putting the car in neutral doesn't help either the rpm just shoot up & keeps going forward.

2003 Chevrolet Malibu. Consumer writes in regards to ignition switch and fuel pump repairs. The consumer stated the passlock sensor had to be replaced, because the vehicle would not start. Also, the fuel pump was replaced, because gas was not going from the tank into the engine, the cruise control occasionally would not work, the service engine light would come on intermittently, and electrical components, such as the radio and windows stopped working.

Stuck accelerator: on 4/22/08, took foot off gas pedal -- car did not decelerate and maintained 47 miles per hour for 0. 86 miles. Made sure cruise control was turned off. Rpm's still stuck at 1. 5. Proceeded through a green light and car continued at 1. 5 rpm's for the next 2 miles. Approaching a 2nd intersection, I decided to pull off to the side of the road to be able to turn off the engine, but there wasn't a shoulder; so applied brakes to turn on to quieter side road. Barely made turn. Had brakes down hard and car still traveled at 20 miles per hour. Hit emergency brake and car slowed to 5 mph. I then put it in neutral and turned off the engine. Took it to spur chevy for repair. They found the prior owner had work done per recall campaign # 04v528000. Nothing came up on their scan test, no fault codes. Cruise control checked out ok. They diagnosed it as the top of the throttle body needing cleaning. This is the 4th time the throttle has been cleaned in the 1 1/2 years I've owned this vehicle. Prior 3 services performed by the seller (barry Dodge) on 8/7/07, 6/5/07 and 4/5/07 were requested as the engine routinely idled at 1500 rpms. The 4/22/08 incident was the first time the brakes weren't able to stop the car. The engine was acting sluggish in the weeks prior to 4/22. The oil change wasn't due for another 1000 miles (barry Dodge or valvoline). I don't use synthetic oil. I always add fuel injector cleaner after an oil change. I prefer sunoco gas and use their least expensive grade.

The consumer states that on 2003 Chevrolet Malibu the cruise control was still active even when the driver had his foot on the brake. The switch on the steering wheel was turned off and the cruise was still activating and speeding the car up. The consumer put his foot on the brakes several times trying to get the car to stop. The consumer finally was able to get the car to stop, but he had to put the car into neutral. The car had to be turned off completely. It set for about 5 minutes and then vehicle restarted. The car sat for a few minutes and then the car was back to normal. The consumer called the dealership and checked to see if there were any problems with the car, and the dealership had not ever heard of this happening before. The manufacturer has not been contacted at this point. The speed was 65 mph and that was with the driver's foot on the brake.
