Very friendly service. Told them I thought battery was bad. I had to have my 2017 Silverado jumped to start it. At first they said no everything looked good from their diagnostic test. I asked them to check again because I hadn���t turned the truck off for 4 hours. They checked They said by doing a ���manual load test��� and yes the battery was bad. Replaced it and All is good. I had no appointment and they were busy but they squeezed me in. Grateful.
