I have had multiple problems since I purchased the car in 10/99. I have had the sun roof replaced once and now needs it again for the same reason; the track broke ($1000 to fix, $2000 if I go to the dealer). The ignition switch has been changed twice because it sticks (it need to be changed again). In 2/00 it started: whenever the car got cold, the car would either not turn on or would just shut down while I was driving. The car was brought to the dealer multiple times for the same problem. He changed numerous parts but was unable to resolve the issue, until a 2004 recall for something to do with the fuel system. About three years ago the engine light came on at which time the dealer replaced the catalytic converter. A few weeks later the engine light came on again at which time the dealer told me it was the head gasket. That, I had replaced by an independent mechanic and then still had to bring it back to the dealer to have the catalytic converter done a second time, and to have the computer reset to have the engine light shut off. Anytime I have work done on the car, even just maintenance, the check coolant light or the engine light comes on and I have to bring it to the dealer to have it shut off. In 9/05 the coolant light illuminated and a day later the engine light came on, I brought the car to an independent mechanic who changed the overflow tank because he believed it to be a bad sensor. After fixing that, the engine light would not go off as well as one of my brake lights. He did multiple tests and determined that it is something electrical, unfortunately he could not pinpoint the exact cause of the electrical problem. For some reason those lights have gone off but I expect them come back on soon.

The catalytic converter failed. Chapman Ford fixed one of the catalytic converters, but the system may still be failing. The vehicle contained a rotten egg smell.
