The dealership had my car since Dec 5th, 2024, and I just picked it up yesterday. I had the hardest time getting anyone to answer the phone when I called, and the voice mail was always full. Joey was my ori picked it up yesterday. I had the hardest time getting anyone to answer the phone when I called, and the voice mail was always full. Joey was my original service writer, and he was, at best, horrible. He is no longer there, but in the meantime, no one at the dealership called and told me he was no longer there. I called for weeks with no answers. I asked multiple times to have Phillip, the service manager, call me, but he never did. I did finally get a hold of Adrianna in service. She was terrific and got my car fixed in a couple of weeks after taking over. I would, however, recommend a different dealership for service. More

Iris Martinez is always great to work with. She explains everything that’s going to happen and answers all my questions. Plus my truck was ready 45 minutes early. She explains everything that’s going to happen and answers all my questions. Plus my truck was ready 45 minutes early. More

This is the very first time I have taken my car in for the oil change, where they told me everything was good. My windshield wipers were not fine they needed replacing and the back wipe was hanging off. the oil change, where they told me everything was good. My windshield wipers were not fine they needed replacing and the back wipe was hanging off. When I went to open the back/trunk door it started to slowly come down hitting me in the heard. That was not like that before, it worked perfectly - it would stay up until I closed it. I bought my vehicle there and have always had repairs and oil changes there, but I was disappointed with the quality of work my car received. More

The Staff is supper, but after 4 or 5 attempts to cure the problem, it has not been resolved. We really like XT6, but wright now we're thinking of turning it into the Lemon Law experts.

This place is the worst! Worked on my GMC Sierra twice and could not fix it. First time they had it they replaced a part (took two days) and it was better but still not rig Worked on my GMC Sierra twice and could not fix it. First time they had it they replaced a part (took two days) and it was better but still not right. They then told me the new part was bad and that it was now on backorder. Went 3 weeks before I found out that the part came in within 5 days and was never informed by the service rep. They then had my truck for another 5 days (no offer of a rental car either time even when requested). Got my truck back and it was exactly the same as it was when I dropped it off 5 days earlier. Service rep and technician lied to my face when they told me it was fixed. I knew it wasn't fixed within 10 miles of driving it. I suspect that they did absolutely no work this second time except to drive it 20 miles and reset the codes right before giving it back to me. It was very difficult to get a hold of anyone there except for the poor parts guy who always answers the phone and has to forward calls and hear frustrated people. I also overheard a lot of this while in the waiting room. I will not return to any Diamond dealership and will share my story with every GMC owner I run into. I have run into that with several GMC owners since and wish they or someone else would have warned me sooner! More
