Northwest Hills Chevrolet Buick GMC

I left the dealership after service and tire rotation to find severe thumping and vibration and had a very difficult time steering the car. I pulled into a gas station to find my front left wheel looked tilted. Driving very slowly, I returned immediately to the service department to find out the front left tire was loose. The fellow who came out to look at the car said 'oh yeah, there is a problem with that wheel.' Before he even moved the car, he brought a floor jack out and tightened the lug nuts in the driveway. The service manager had the audacity to tell me that when you rotate the tires the rust on the wheel sometimes falls off and causes the wheel to loosen. The lug nuts WERE NOT TIGHTENED and if I had driven any farther the wheel would have sheared the lug nuts off. As I would have been on Route 8,(if I had even made it that far) the results could have been disastrous. Needless to say, I am irate and insulted at having such a lame story told to me. I am seriously considering filing a report with DMV. This is inexcusable. Will I come back to NWH? I highly doubt it. It cost me eighty dollars for service that wasn't worth 50 cents.
