“I had 2 kids in the car,the accelerator pedal stuck,car kept speeding up.. I was using both feet on brake & er brake as well!! I was swerving in & out of traffic,running red lights & praying for our lives,we got up to 85 miles per hour in a 35mph zone!! The car was revving out of control & black smoke was coming out from under the hood! I managed to slam it into park & we all jumped out & ran,very frightening & almost ended in a collision. The intake manifold gasket cracked at 1yr old and 10,000 miles,the tires needed resealing at 5000 miles. Ridiculous!!”

“Coolant leaked into engine caused problems, wouldn't start half the time, couldn't fill up without gas pump cutting off constantly (took 20 minutes to fill up). Took car to dealer and other shops spent tons of money problem not solved. Got so feed up with this car I pulled the tags and bought a honda. It is really unfair how the manufacturer of this car was allowed to get away with putting out such an inferior product. There should have been a major recall on any number of these problems. I was never notified of any recalls or the class action law suit.”

“Recently we experienced a very strong fuel smell in the passenger compartment after driving our car. When we opened the hood, it appeared that fuel was leaking from a part all over the hot engine. We got it to the dealership who diagnosed the problem as the fuel pressure regulator leaking. The fuel pressure regulator was replaced and there does not appear to be any fuel leaking at this point. Our mechanic stated that the slightest spark in the engine could have started a fire. Cost of repair: $196.19.”

“My 2003 Grand Am suffered a failure of it's fuel pump on feb. Of 2005 during a trip to the bay area. I was fueling up at a willits ca. Gas station on a friday afternoon . I filled up my gas tank and then attempted to start the Pontiac. It wouldn't start. I was told by the mechanic who looked at my car and who made the subsequent repair that it was due to a manufacture defect. I had just filled up and my tank was at one quarter full prior to this and when I attempted to re-start the vehicle, I could not get the motor to turn-over and start. …”
