My daughter visited this dealership looking for a newer Terrain and to trade her 2019 VW Beetle Special Edition. While they were working on numbers, she told Larry what she was hoping to get on trade. He directly mocked her and told her that he couldn't believe her dad let her pay that much for the car last year! Insulted, she left and went to another dealership who got her into a great 2025 vehicle and met her expectation on trade in value. ($10k higher than what Larry proposed) As a dad, I don't appreciate how she was treated and could NEVER recommend this dealership to anyone for how we were treated! Disappointed at the lack of respect!

Had an oil change done. Next day there was a 10 inch diameter oil spot on my driveway and oil dripping from the skid plate. Took the vehicle back and was told everything looked good and if I wanted to investigate further to make an appointment (and another trip) to look further into the engine. The oil drip stopped before I the appointment. Not lost on me that oil can be spilled on filling but either clean it up or inform me. Don't appreciate oil on my driveway or the need to make multiple trips to verify that it wasn't a bigger problem.

I had an outstanding experience getting my 2022 Chevy Traverse serviced here. After bringing it in for a transmission issue, the team diagnosed it quickly and even provided a ride home so I could finish my workday. My service advisor, Brian, was exceptional?he stayed in constant contact with updates. I was relieved to find out the replacement was covered under the powertrain warranty. They sourced a new transmission locally and finished the job right on schedule. They even picked me up to collect my vehicle! I?m driving away with total peace of mind. Highly recommend Brian and this service department.

Happy with service so far, NOT HAPPY with a transmission repair at 51000 miles and my warranty expired since it is a 2018 model bought new in 2019. Almost lost the engine at 500 miles when the oil came out due to a bad hose connection. So yea won?t be buying GMC products. Thanks!

Jeff made buying the Canyon a pain free experience! Everything was straight forward and he took the time to explain all the options and had everything in order with the trade in.
