On Friday, August 19th, I discovered that my right headlight was not working. I called Wally McCarthy Cadillac in Roseville who had been servicing my car, and after some discussion, I was told to bring it in, (i.e., "how soon can you bring it in?"). I brought it in within 1/2 hour.(at c. noon). Their courtesy van brought me back to work. Their service advisor said I would be called when the job was completed. I was not called back, and their courtesy van driver said he only did pickups until 4 p.m., so I called them and asked to be picked up and brought to the Cadillac service center at 4. The courtesy van came early, but I was ready and was driven back to the service center. However, when I got there, the service advisor had not yet gotten any report from the mechanic working on my car. So, I waited for him to do so. After 1/2 hour, he came back and said that the light assemblage had gotten loose and had shorted out a circuit board, and it would cost me over $500 to replace. But since it was nearly 5 p.m., they would not be able to do that until MOnday. I asked about a loaner, since I needed a car over the weekend. The service advisor said that he would speak to his manager. Another 1/2 hour later, he came back to say that his boss would not authorize a loaner. I was upset and told him that they this was a bad experience and that they didnt care about me at all. I was told that when I paid the diagnostic fee ($58.00) I could retrieve my car. I paid the fee and left. However, when I got into my car, the dashboard "levelling" light went on and stayed on. Also there now is a "whirring " sound in the dash that wasnt there when I brought the car in. Early Monday morning, I called and asked to speak with the service manager Olson. He was unavailable but I left a detailed message regarding these new problems. He returned my call later in the morning and left a voicemail saying that all they did was look under the hood, and therefore my complaints were not connected with their diagnostic assessment. Basically, he denied that there was a connection between my new problems with the "leveling" light / dashboard sounds and their agency. Neither of these were present when I brought the car in on Friday, and a coincidence (i.e., these just happening to give out that day) is very unlikely.
