Long post below. I would look to another Buick Dealer or GM Dealer to service your car.
Safety of any organization should be the number one concern, next should be customer service. Both of these attributes I failed to receive here.
Saftey: I brought my car in for service with a noise I said was coming from the passenger side of my car. I said I believe to be either the wheel barring or muffler. The result was my car had a bad oil change at the last place. I never got to see evidence from this. The said everything else checked out. I picked up the car. I had to pay for the oil change and the time it took to look at my car. Next day I was finally able to drive it at a high speed (noise happened only at a high speed). It was still there. I texted them to say the problem was not fixed. No response. I then decided to call another dealership. Told them the same info. Did not tell them I was at this dealer. Turns out that my right front hub and bearing needed to be fixed! HOW WAS THIS MISSED AT THE INSPECTION OF MY CAR???!!! Glad I trusted my gut to get another opinion. I do not believe driving with damage to the hub and bearing is safe.

Customer Service: Called to make the appointment. I told the person on the phone that I wasn't sure I had an extended warranty. All I knew is that it went to 60k. She looked up my name and said I wasn't covered under warranty. I hung up the phone and discussed with my spouse. Called again and said can you make sure we are covered under warranty. This time I was told I was.

Customer Service: When I picked up my car that I later found out was not looked at properly, it was dirty. When under previous ownership, when your car was in the shop it was returned to you with a fresh car wash. This did not happen.

Customer Service: I paid for a diagnostic that wasn't fully completed. I had to pay for a lyft to pick up a car that was unsafe to drive.

Customer Service: I told them about this issue not being fixed. No response back. My money was wasted here.
