Dropped off my truck at 8:30 for a leaking power brake booster repair. Was told there was also a recall which was then also scheduled to be done. Both under warranty. When I called at 4pm, I was told that the service technician did not find a leak. I guess he didn’t look at the hydraulic fluid soaked floor mat under the brake pedal. At pick up, I was handed my keys with no mention of whether the recall repair was made. It was not. Total waste of time. It was my first time going to Performance GMC service, probably my last.

I had a great experience at Performance Buick GMC yesterday purchasing a new Sierra 1500. Will and team did a great job walking me through the process of reviewing the right deal and getting all the documents completed. I love the new truck.
