Diamond GMC Cadillac Palmdale

Robin was very helpful and friendly. Unfortunately, the "techs" she has to rely on seem to be inexperienced and unable to perform computer/electrical recommended mods, even with GM Serv Unfortunately, the "techs" she has to rely on seem to be inexperienced and unable to perform computer/electrical recommended mods, even with GM Service Bulletin guidance, and even after calling GM on the phone. Their ability to interface with modern modules (BCM in my case) seems limited. They DID change the installed options, but not the correct one. Not only do I NOT have RPO ZW9 set, but now the menus for vehicle option preferences now include interface selections for a remote door lock system (Key FOB), an option NOT possible on my 2016 2500 HD. Robin did NOT charge me for the "techs" experimentation, and I thank her. However, I must continue to look for another source to get RPO ZW9 set in the BCM to eliminate turn-signal hyper flash. Another GOOD thing... the popcorn machine was working! I'll be back just for that! AND, I'll ask for Robin to be my Service Advisor. I should have insisted that I be able to speak directly with the "techs" to better understand what they did. More

Robin and Iris are both great with customers. I love how they work as a team and get all the clients checked and processed. The wait time is not bad at all considering how many cars are coming in I love how they work as a team and get all the clients checked and processed.

They had my car for two weeks, three days before they even looked at it. My service rep didn’t call me, I had to be the one that always reached out for updates. When I questioned why I had to pay for so even looked at it. My service rep didn’t call me, I had to be the one that always reached out for updates. When I questioned why I had to pay for software update when my car is supposed to do that automatically I then had a much more expensive estimate to fix the problem. I was also told that the vibration noise from passenger seat was fixed however it is not. Wish there were another dealership in the area to take my car to. More

I advise you to be prepared to be con, sold and packaged going to this dealership. Sales person are friendly and trustworthy but unfortunately, their sales manager belittle them in front of the customers. I would not trust a word out of this man, BoB or any of the sales manager! I doubt it his real name. Worst experience in my life! More

The ease of buying having the car delivered was perfect! My only issue was that the car did not have the correct manual, and it took over a week to get it, because it had to be ordered.

My Saturday morning oil change was a delight with Francisco and Robin. The seating is the only issue I have, you sit back in the chair or couches and it's very difficult to get back out because you Francisco and Robin.
