2007 GMC ACADIA User Comment / Complaint

Noticed a sudden shaking in the car when driving more than 25mph. felt the car was unsafe to drive, so left it at a local tire and auto shop for inspection the next morning. the technician called to inform us that there should be 6 bolts that attach the driveshaft to the front differential. the car only had 3 of the 6 bolts left and of those 1 was bent. they were also all loose. he suspected that they were not tightened correctly at the factory. the car was towed to the nearest dealership for inspection and repair. this car was purchased in 3/07 and currently has 12,000 miles.
