March 30th, 2007 car ran rough and service engine soon light came on. A bad odor also was permeating into the car while going down the road. Car went back to the dealer on the 31st and they had the car until the 3rd of April. I drove the car about two miles and the car did exactly what it was doing before when I dropped it off. I dropped the car back off the next day on the 4th they had it until Saturday the 7th. They said they changed the spark plugs and that was what was wrong. I drove the car and everything was fine until Friday the 13th. I went to start the car in the morning and it wouldn't start right away. When it did it stunk so bad from to much gas from trying to start it. I ran it that day and it ran rough a few times and didn't call the dealer. I loaned my car to my brother Friday night and I didn't tell him about the starting problem or the running roughly. He went to start the car after work on Saturday morning and it wouldn't start right away for him. He got it going and he told me that it ran rough and bucked and jerked. When he brought the car back to me it sat in my driveway for about four hours. My wife went to start it and put it into the garage for the night and she could not get it to start she had to come and get me to get it going. I called the dealer on Monday the 16th and they told me to bring it in the next day. I did so and they sent it to a garage to have it looked at. About 2:00 on Wednesday the 18th I stopped to see if it was fixed and they said it was that it was the spark plugs again the garage didn't put premium plugs in. They told me that they washed my car for my inconveniences. Also the fuel mileage on the car was 20 mpg which is extremely low it should get 30-32 mpg. I told them this also. So I got the car back and today the 19th of April the car is having problems running properly. I returned the car and they wont call me at all. I feared my children's safety in this car.

Vehicle was having a problem with the catalytic converter. The mfr. Was unable to repair the catalytic converter because there were no parts to repair it with. Dealership does not know when the parts will be available for repair. The vehicle was taken to the dealer in April but as of May 17 no new catalytic converter was available from GM to replace the defective one.

Fuel tank and sending lines need to be replaced due to O-rings improperly fitted on fuel pump. In July 2000, vehicle was making a knocking noise when turning or going over a bump. Front/rear transmission mounts were defective components. Dealership put a sealer on this, but it failed to correct defect. The dealer had replaced motor, transmission mounts, power steering lines, gasket to catalytic convertor and switch for heated seat.
