Diamond Chevrolet GMC of Banning

THEY ARE A ROTTEN BUNCH OF LIARS & THIEVES... NO INTEGRITY!! I took car in for oil change & service. Oil change NOT completed, (I guess because it is a free service), & now there is fluid or oil drops coming out I took car in for oil change & service. Oil change NOT completed, (I guess because it is a free service), & now there is fluid or oil drops coming out the bottom of the car. The next day, I checked the oil myself. The only oil in the engine was black & thick, like tar. Clearly, NO OIL CHANGE WAS PERFORMED!!! I now have to commute & go back a 2nd time. I called & spoke to Mark, service manager. During our conversation on phone, he tried stating that it was my fault because I hadn't been there in awhile, (I WONDER WHY)?!?!?! He accepted NO RESPONSIBILITY for any wrong doing. When I take car back, I will only allow them to complete the oil change & find the reason for the leak from the bottom. I will be watching EVERY move they make & I WILL NEVER RETURN TO THAT MESS, EVER AGAIN!!! More

Warranty lies Had such a great experience buying my Chevy Silverado, I figured my next encounter with Diamond Hills Chevy would be just as good. WRONG! I was conne Had such a great experience buying my Chevy Silverado, I figured my next encounter with Diamond Hills Chevy would be just as good. WRONG! I was conned into buying the most expensive warranty they offer, the salesman explaining it's bumper to bumper and I wouldn't pay a dime! And it's SO convenient because you get a rental car no matter what! Fast forward to today (4 months of owning my truck) and the AC has leaked and flooded my interior. Turns out my "super awesome warranty" somehow doesn't exist and now I have to pay a $200 deductible for them to look at my truck. And the icing on the cake is I have to sit there and wait for them to diagnose the issue and time frame to be fixed before they'll give me a rental car. Because we can all just go into work late, right? So why don't I go talk to the people that sold me the warranty and did my paperwork? Oh because CONVENIENTLY neither of them work there anymore. Talk about getting taken advantage of... what a waste of money for this useless warranty. My actual salesperson was fantastic (not the one that sold the warranty, but the one that sold the actual truck)... so if you decide to come here just skip out on anything extra! More

Just an oil change So I made an appointment for 2 pm on a monday for an oil change. I ended up dropping my truck off an hour early, since i had some running around to d So I made an appointment for 2 pm on a monday for an oil change. I ended up dropping my truck off an hour early, since i had some running around to do with the wife. When i made the appointment they told me an hour and a half if i was to wait for it. So when I drove up I was not greeted by anyone. I walked inside the service dept. And they had on guy working. He was with a customer so I waited, when he was finishing up with his customer a man walked in right past me and started his business of getting his car back. Hello there is a line.... but after all that crap. Which was about 20 minutes. I finally got some help. He told me they will call when its ready. So it was 1pm when i dropped it off. It got till about 4pm and i figured they will be closing at 5. So I went to go see what the deal is. When I got there I was not greeted once again. I stood right in front of a service writer for about 5 minutes. He was on his computer so I waited for him to finish and ask if I need help. But once again NOPE. Once I saw him staring out the window i asked him if he could help me. He said i needed to go to the service writer who wrote me up. So i did. He asked my name and looked through his paperwork and found my truck was done. With no calls. He gave me my keys and said your truck is out there. Nobody pulled it up for me or anything. I will be going back to moss bros from now on. More

Frank was Great! Awesome Service! Most of my transaction was done on the internet, all I had tho do was come in answer a few questions, sign paperwork and drive off Awesome Service! Most of my transaction was done on the internet, all I had tho do was come in answer a few questions, sign paperwork and drive off with my new car. No fast talking sales man, they listened too my needs and the deal was done. They even reduced the down payment by over half off what I told them I could put down. Frank was GREAT! More

Oil change and no ""car wash" My wife always looked forward to her visits and was willing to spend the time at the dealership .....knowing at the end of the service, she would hav My wife always looked forward to her visits and was willing to spend the time at the dealership .....knowing at the end of the service, she would have a Clean just washed car. Now that there is no more washes I'm afraid she won't be taking the car in, If I have to, I'll find a place closer and cheaper!! More

I was told it would take an hour to an hour and a half. Howevr, it was ready in just under an hour. We bought our car from Diamond Hills Auto 2 years ago. Our salesman, Frank Goodall sold it to us. We know Frank personally as we have bought other vehicles from him. He has always been great about answering any questions we have about our Terrain. All of the employees have always been courteous, friendly and knowledgeable. The customer service is remarkable, something you don't often find it today's world. More
