Disappointing service for it being a “Cadillac” dealer. I get better service when I go to Nissan, Infiniti, and Mercedes dealer. I get better service when I go to Nissan, Infiniti, and Mercedes dealer. More

The service during my last visit was disappointing. I had a scheduled appointment for an oil change, but my car was there for approximately three hours. I also requested a car wash, but at the end of t I had a scheduled appointment for an oil change, but my car was there for approximately three hours. I also requested a car wash, but at the end of the visit I was told they had run out of time, which was frustrating considering how long the vehicle had already been there. When the service was completed, I felt rushed out because the location was closing. No one took the time to review the service with me or explain whether any issues were found, if everything checked out, or if there was anything I should be aware of. I was essentially handed my vehicle and rushed out the door. For a scheduled service appointment, I expected better communication and a more thorough customer service experience. More

Service writer (Ed Brady) was terrible about returning phone calls and following through with promises to call and keep us appraised of the ongoing service issues. I had to go to the dealership several phone calls and following through with promises to call and keep us appraised of the ongoing service issues. I had to go to the dealership several times while my car was being serviced to obtain updates.. Unacceptable! Ed said he was going to top off the windshield cleaner fluid and replace the reservoir cap, never happened. I’m afraid my wife and myself will be going to another dealership for service and purchase.
