I don't like leaving negative reviews but I have been bringing my vehicle for service here since day one. I find that the service department should do more to assist customers. I can not say that I have ever had a stellar experience, my last experience was that my vehicle was in at 10:45am for the 20k service which I was told would take 1hr. I asked for a loaner and asked to be called as soon as my vehicle was ready. I had to call at 12:45pm and was told that my service advisor was at lunch and no one but him could tell me if my car was ready. I proceeded to drive back to the dealership, my vehicle was done and parked out front. I went in and was told that my service advisor was still not back and he hadn't completed the paperwork so the car was not ready to leave. After explaining that it had almost been 3 hrs, that my car was sitting there completed and that I had appointments to get to they had someone else finish the paperwork so I could leave. There has to be a better way to handle this! A customer should not have to wait that long over paperwork! If I hadn't pushed the issue with needing to leave I'm assuming that they would have waited for my service advisor to come back from lunch and finish the paperwork before I would have got my car. I would hope they do something to address this so things like this don't happen again in the future.
