Diamond GMC Cadillac Palmdale - Service Center

Brought my vehicle in on Dec. 21 with a check engine light, and a transmission service warning. They diagnosed it told me I needed to service the transmission and change the fluid 21 with a check engine light, and a transmission service warning. They diagnosed it told me I needed to service the transmission and change the fluid. #1 this cost me $1500.00, I have never heard of a $1500.00 transmission service in my life, never doing that again. Did the work and a couple of days later the same issue returned. Brought it back on Dec. 27. And it was now an issue with the electronics in the shifter. They ordered parts and Terri told me they should have them by Wednesday the Jan. 3rd, since it was only a few days, told her to just keep the vehicle, this second visit for the same issue was going to cost me another $800. The third came and went with no word. Tried to get a hold of her. Has issues returning calls. Finally on Wed. the 10th found out the part is back ordered and not available and was told possibly mid-February. GM was on a nationwide search for the part. Decided to remove my vehicle from Diamond and I then took it to another local GM dealership. They had obtained the unavailable part, they found it locally at another dealership, and had it fixed within 24 hours of dropping it off. And on top of that they figured out how to do it under warranty, it cost me nothing. Now that's service, Diamond needs a lesson on this. Terri needs work with her people skills, she has a take it or leave it attitude. And if I am going to compare her to the other service advisor at the other GM dealership, complete night and day, she fails. I will not be back. More
