Diamond GMC Cadillac Palmdale

I dropped my truck off for just an oil change at 830. My service rep stated it would take an hour or hour and half. She left shortly after that and didn’t return. I sat in the lobby for 4 hours before I My service rep stated it would take an hour or hour and half. She left shortly after that and didn’t return. I sat in the lobby for 4 hours before I realized my truck had been done for presumably a couple hours. I then had to ask for help from someone else to check out. I understand things happen, but communication within the department and the customer would go a long way. More

2nd time I have not been contacted when my vehicle was ready after having my oil changed. Dropped my vehicle off at 9am and had heard nothing by 5pm. I called and I was told they weren't able to get throu ready after having my oil changed. Dropped my vehicle off at 9am and had heard nothing by 5pm. I called and I was told they weren't able to get through to my cell number by using their landline. No other steps were taken to resolve the issue. No text was sent and no email and Nothing is wrong with my cell phone. Was given nothing but excuses when picking up my car. Will likely not be coming back to do business here. More

I brought my truck in for a transmission fluid exchange and brought it home where it was leaking transmission fluid in the garage. It seems the threading was stripped on the plug. I took it back and the se and brought it home where it was leaking transmission fluid in the garage. It seems the threading was stripped on the plug. I took it back and the service team inspected it right away, and although they said the damage couldn’t be proven to be their fault, they said they’d take responsibility. Initially they told me it needed a new transmission pan and that they’d have it ready for me that same day. At the time they said it would be ready, I received a text saying the part they had didn’t fit so they had to order a new one that would be in the next day. The part indeed was replaced the next day, after I lost a full day of planned vacation due to apparent negligence when the service technician didn’t thread the plug correctly in the first place.

Service people are great. But the office and amenities are lacking, kinda embarrassing compared to other dealers. But the office and amenities are lacking, kinda embarrassing compared to other dealers. More

Service brake monitor light went offf. I lnow my brakes were showing 60% front, 80% rear prior to the monitor going out. Went in for oil/fuel filter change. Told them about brake moni I lnow my brakes were showing 60% front, 80% rear prior to the monitor going out. Went in for oil/fuel filter change. Told them about brake monitor. Tech said front brakes at 3mm. Recomends new brake pads. Wrong, i knew i didnt need new pads. That tech went on lunch. Had a different tech take tires back of and measure in front of me. Fronts were at 5mm. No nee pads needed. If you dont have brake monitors, dont try to sell me $400 brake pads that are not needed. Talked with service manager. Tech blatantly lied. Know these new trucks are glitchy, have known issues(transmission valve body). Im going to need to bring it in, but dont lie to me. Dont have customer service that pushes people away. More

I brought my car in around 1:00 for a routine service check and I stayed in the waiting area. After about 30 minutes Natalie came and told me that they had found a small leak in my oil pan and asked if check and I stayed in the waiting area. After about 30 minutes Natalie came and told me that they had found a small leak in my oil pan and asked if I wanted them to repair it and that it would take a couple of hours. I said okay and they got a lyft to take me home. After several hours I tried calling back to see when my car would be ready but they had closed at 5. I never received a called to tell me that they needed to keep my car overnight, which I was furious about because I had plans for the evening and I needed my car. Apparently the seal had to sit and dry for 10 hours before the car could be driven. I would have at least appreciated a phone call letting me know of the delay! More

Took 38 days to fix a transmission cooling line. Unacceptable.
