I schedule an appointment for Saturday at 8:20 in the morning was on time to get an oil change/filter, transmission fluid/filter and front end alignment. Was giving an estimate of $800 + and would be done by 12:30 & 1:00 that day 4.2hr. Which neither were true. Arrived early at 11:45 and told the service associate I was there to pick up my car they said it was not done. I waited till 12:31 and then walk back up to them and ask them if my car was finished they told me there was a problem, that they put in the wrong transmission fluid in my specific 2016 Cadillac ATS that they were draining the wrong fluid and putting in the correct fluid. I asked why I was never notified of this they had no answer. So I waited till 1:30 and approach the service technician again and he had said a hose blew on their equipment while they were changing the motor oil this time which resulted in motor oil all in the engine compartment and dripping underneath now it was 2:00 and they still had not done the front end alignment. I told them to cancel the front end alignment because I had no confidence in their ability to do the job correctly. Finally was able to get my car out of there at 2:15, with oil all over my engine compartment completely unsatisfied. When you take your Cadillac to a Cadillac dealership you expect them to know what they are doing. What specific parts and fluids go into your vehicle. I didn't take it to a fly-by-night uncertified technician shop but that's how I felt. In the end I had to take my car to the carwash with Degreaser to get rid of the oil that was left in the engine compartment.
