I was very disappointed with my service today. They made no effort to communicate with me during the service. I dropped off in the morning and received a loaner car. I hadn't heard a word from them by 3PM so I called. Receptionist put me into service rep voicemail. I still haven't heard back from my voice mail this evening and dont expect it now. I showed up at the dealership and talked to guy in service bay. He said service was completed and he would bring my car around. I waited another 45 minutes as no one approached me. I finally went to receptionist and asked for service manager and found out he had left for the day. Another ten minutes go by and a service rep gives me my service report and showed me to car. No explanation of how my service went. Then he couldn't find my keys but found car in lot running. How long was it out there running? The 45 minutes I was waiting for someone to help me? I really didn't feel welcome or appreciated by this dealership or its service people.
