Purchased new 2008 Aveo in April 2007 which has excessive vibration. I took into dealership and was advised it was due to the ac causing extra work for the motor. Since it was summer time I went on my way and dealt with this vibration (which only happens while in drive) it is now January and no ac is being used. I took the car back in to the dealership and was told yes there is excessive vibration and we will look into it 4 hours later they called to let me know they cannot find the problem and even contacted the gm advisors and are all in agreement with this issue however since there is not service bulletin or recall regarding this I will have to just deal with it and wait and see if something comes up with a fix. I cannot believe I am having to just deal with a brand new car with issues. . . This car has been taken in several times already. . Shifter locked up and would not move from park so they replaced that. . . Then car dies on hwy and was towed into the dealership had to fix something that had to do with the throttle, paint in now peeling and only has 11,000 miles any help would be great.
