Took our truck there after the upper A arm broke. Truck sat outside for 3 1/2 months in the hot elements during the summer waiting for parts to be re-engineered. The service updates were terrible. Truck sat outside for 3 1/2 months in the hot elements during the summer waiting for parts to be re-engineered. The service updates were terrible. Everything seemed to fall on deaf ears. Being that the parts were an issue to obtain, (GM's fault,) you would think they would offer some kind of loaner car. The customer service was so terrible< we had to contact GM directly. We were supposed to receive our truck back looking like a ("polished penny") and when we received it back, it was an oxidized mess. I'm not one to complain. This dealership did not give one iota of ---- about us or our vehicle. Some people think nothing of their automobiles. Us, we treat them as show cars... We have always been a GM family, and my in-laws are retired from GM. We won't let this detour us from GM. Our choice of our dealership will change though. Thank you Chris Leggio for the wonderful customer service and experience. More

Beware of this dealership service Dept. There was damage to my Cadillac Escalade after being in their possession for a week. Delearship failed to assume responsibility rather provided me wi There was damage to my Cadillac Escalade after being in their possession for a week. Delearship failed to assume responsibility rather provided me with photos of a different vehicle with a different ID. Management refuses to accept responsibility. My vehicle was driven without my consent for over 100 miles. Documents given upon delivery state technician drove my car 35 miles. Service advisor had requested my permission to drive my vehicle home “to get it to act up” advisor denied any permission. This shop violates the trust consumers provide with their vehicles. More

Chelsea is a great person to work with. She’s extremely knowledgeable in her field. It’s been a breeze to get in for service through text or call. She’s personable and poignant.

When my vehicle was brought to be when the service was done, my steering wheel had grease or oil marks. When I asked the guy about it he said it was like that when he brought it from the shop.

Takes forever for anyone to acknowledge you’re there. No body meets you when you pull up like other GM dealerships. When you walk into the office area several people sitting at computers or their phones. No body meets you when you pull up like other GM dealerships. When you walk into the office area several people sitting at computers or their phones. One person helping a customer. Had to wait for the one person helping someone to finish and finally ask me what I’m here for. Everyone else never even looked up. No communication on the status of my truck without me having to reach out and ask. More
