Your service writers don't communicate with one another! I experienced a serious with my vehicle 4 days before my scheduled appointment and I stopped at your dealership and spoke with one of the service writers, after some persuasion on my part he checked for error codes from my vehicle. He said there was a fuel delivery problem. I brought the vehicle in for service on the appointed day and explained whet had happened 5 days earlier. The vehicle was kept for 2 days and was called and told they found nothing wrong! I had done some research on my own and found that the problem very likely was the fuel pump control module. I was told that all tests indicated that there was no problem. I refused to take back the vehicle until that module was replaced. I ended up paying $444 and some change for test and the part plus installation labor. Guess what! The vehicle now with no further problems. I do not feel that it is my problem to advise your mechanics on what needs to be fixed!
