Cruise Control problems of the 2004 Saturn ION

My fiance and I were driving down the road about 40 45 mph and the light up ahead changed yellow to red just before I could come to a complete stop, my car accelerated I held both feet on the brake and the car kept wanting to inch forward itseemed as if I held the gas pedal down to the floor I got within 2 or 3 feet from the car in front of me out of instinct I quickly put the car in neutral and shut it off had I not I would have rear ended the car in front of me I then waited a minute or two tops put it in park and started it, it acted normal I thought maybe there was and object or something that may have slipped by my feet while driving or my floor mat moved there was nothing there . There has been other times like right after starting it up it revs to the highest rpm possible as if its going to blow up I hurry and shut it off wait a few minutes and try again, and another time I drove about 2 miles going down the road at 45 mph as if I had cruise control on when my car doesnt have that feature which is really scary I dont know what to do please help thank you.

While slowing and preparing to stop for a traffic light, the vehicle began to accelerate, rpm's increased even though foot was off the accelerator. Vehicle was difficult to stop and required more than normal foot pressure on brake pedal. Once vehicle was stopped, engine continued to race. Problem was corrected by turning off the key. Problem has occurred three times randomly over the past year. On all occurrences, the cruise control was not in use.

By 3500 miles (after 1500mi when we could have returned it), the front passenger turn signal burnt out. The car was also sputtering when we started the engine. The mechanic found a cracked head, that we were told was probably present when we purchased the car; had we known we would've returned the car. We were given a rental car, but had to drive 45 min one way to get to Saturn of green bay. Within a month, the front driver turn signal had burnt out. The wiring was replaced while we waited 2 hrs with our 3 year old. We had to drive 1 hr 1way to Saturn of appleton for repairs. In Aug 2004, the car was making a noise when we turned onto a steep grade. In mi for vacation, we had to drive over 1 hr 1way to Saturn of troy; the swaybar and mounting brackets had to be fixed. We waited for over 2 hrs with our son while it was fixed. In sept 2004, the front passenger side turn signal had to replace the resistor. We drove 1 hr 1 way for the repair, and had to wait 2 hrs with our son. We had asked about the cruise making a funny noise, but it was checked and we were told it was fine. In April 2005, the cruise stopped working and had to be fixed. It took over a week for the part to come in, and almost 2 weeks for it to be repaired at Saturn of green bay. I had to go to the dealer 30 minutes early, be driven over to my school where I teach, walk to my second school I teach at, and wait for a driver to pick me up (20-40 min past when I was done for the day). Despite everything we've been through with a new car that should need minimal care at this point, we've been basically told that we should take the $2600 hit to buy a new car while the dealer breaks even. This is poor salesmanship, and we will not be purchasing Saturn products any longer.
