I am surprised as I own 3 late GM models. Superb.

I've owned cars from Germany, Japan, Australia and USA. They all had typical "poor quality". As it turns out, the laws of thermodynamics applied to each one of them. Every single one of them had something that needed fixing.

Sorry to hear of the NVH issue with the car and the technical ignorance of the service. Did you check in to the "lemon laws" for your state?
