Since new, car has been at dealer 7-times for vibration in front end, 5 times for excessive steering backlash, 3 times for steering wheel shimmy during braking, and 2 times for engine high temperature. (5 tires have been replaced. 4 rims have been replaced. 3 sets of brake rotors have been replaced. Power steering pump replaced. Power rack and pinion unit replaced. Front end aligned. Tires balanced 9 times.) vibration still exists at highway speeds with car pulling to the right.
I have a 1999 grand am gt that I bought a month and half ago. All of a sudden the car started to over heat and losing a lot of coolant! We replaced the theromstate, radiator cap, flushed the sytem and still was over heating!!! Now the car is broke down and needs a head gasket or even need to replace both heads!! Nothing but problems with the whole coolant system!!.
