A better question would be what hasn't gone wrong with it. Immediately after getting it home the steering wheel broke while driving it almost sending my son into the ditch.
Shortly after that whenever it was first driven it would die out for about 2 blocks before it started running o.k. After having it in the shop twice for the same problem it finally just started running again.
In October, the heater core went out on it with a $200 repair bill.
In January, the heater core went out on in it again with another $200 repair bill.
Last weekend the rod bearing went out on it. I was just called and told it's a MAJOR problem because there is metal everywhere from it It's probably not even worth fixing.
My advice is to not buy this year and make of car. The only good thing about it was the gas mileage.
The '94 Grand Am is known for problems. My '98 Grand Prix (see review) was in a bad accident not too long ago and the body shop gave me a 1994 Grand Am GT. The car had 117,000 miles on it and the dashboard rattled like crazy, the left turn signal sticked, it sucked down gas, and was leaking a lot of coolant. Before my car was done I brought it back and they thought it was a sensor and told me to keep an eye on it. I was so happy to get my car back.
