We bought this Buick brand new with 1 mile on the odometer. When we test drove it. It had a vibration .The dealer said it was a tire out of balance and would be no problem to fix. We have had this car for 10 weeks now and have only drove it 10 days out of the 10 weeks now. This is the 4th time in the shop. It has been in the shop for the last 5 weeks now. This car has had the front end realined,the front axles changed, 2 sets of tires. If this is GMC best thin I will have to buy a import the next time. And one thing to add, it leaked on the passager side when it rained. We called GMC to complain and asked for a new car.
