I purchased the car in October 2003 and the car was great. In March 2006 I started having problems where the car when attempted to start would take a few seconds extra and then start, then 6 months later I was driving down the street and the car just cut off in the middle of an intersection. The car restarted about 10 minutes later. Then in November this started happening more an more frequently. One night in December the car cut off and would not restart at all. I was able to pull of the road. I waited an hour and still the car would not start. I came back the next day and the car would not start. I got the car towed to a mechanic who said that he thought it was the fuel pump so I replaced that and the car worked for 2 days and then the same problem again. He then tested the car and saw there was no power going to the fuel pump. …
Referring to the passenger-side headlight: while driving my children home after it was already dark, I noticed that the passenger-side headlight seemed a little dimmer than the driver-side headlight. I also had on my driving lights that are below the headlights. We were on a particularly dark road where there is a tendency to be deer, so when it was clear of opposing traffic, I put the high-beam lights on. After putting the high-beams on, all the lights.....headlights, high-beams, and driving lights went out....while I was driving. A red "service" light came on the dashboard. I was very startled at this and had to pull over to the side of the road. I switched the lights off and then on again and nothing would work and the "service" light remained on. Fortunately, I was not in a high traffic area or this could have been a very serious accident waiting to happen, especially if I panicked. …

The 2003 Pontiac Sunfire is an inferior car. Mine currently has approx 57,000 miles on the odometer. The day after I purchased it brand new, it would not start. The dealer came out and replaced the battery. The car had white paint overspray on it. The dealer repainted it. The sunroof malfunctioned and the dealer fixed it. The turn signals kept going out & it was fixed due to the recall. The dash had to be taken out due to the fact that the air was not coming out of the vents properly. The power window driver's side failed completely around 38,000 miles & passenger intermittently would not work. This was fixed at my expense. The car has been in the shop for brake problems numerous times. I had the dealer check them several times while still under warranty and they finally replaced them at their cost because they said it should not be necessary given the mileage on the car. …
Engine & cooling
Dt: bought vehicle brand new and it has been in the repair shop 15 times for the same problem. It is dying at random for no reason and will not start back. Sometimes it takes up to 20 minutes or longer before it will restart. Mechanic had no idea why this problem happened. The car was taken to different dealership, but no one could figure this out. Two weeks ago the car was subjected to a pressurized test. Consumer has the car towed on 5-31-2005 because it died, and did restart. There have been lots of problems to try to correct, but nothing worked. The car was kept at the dealer for up to two weeks at a time.
Every time I let my car sit for 2 hours or more, I start it up and the belt on the tensioner squeak for 15 seconds. Also the battery light comes on and the rim fluctuate between 1,000 and 2,000. When I drive it the battery light will continue to stay on but every time the air bag light turns on and I'm accelerating the engine will not shift, the rpms will rev up to red line if pushed that far, eventually the light for airbag and battery will shut off and it will shift. Sometimes when I hit the gas pedal while this is doing this at night, my dashboard as well as radio lights will shut off until rpms go down to 2,000.
