Do not trust their prices. All prices are simply lost leaders to get you in the door then they add 10k to it. Save yourself the time and effort and find a more honest up front dealership. If you you proceed with them have them add all there extra fees and email you the price. It would be a complete waste of time to actually go to the dealership without getting past the made up bait prices first in my opinion.

They advertise good prices online but will not honor them. I understand some dealers are doing market adjustments due to the current restrictions, but the honest ones will disclose that online so there are no surprises. On top of that they have a mandatory “diamond package” that is included in all vehicles. All in all the price was about 8K over the online advertised price.

I took my Silverado 1500 to Diamond Chevrolet to have a airbag replaced under warranty. When I spoke with the Service Rep Ryan I told them a motor mount needed replacement and asked for a quote the dealer would charge for the repair. I was quoted a price of $670.00. I declined the service. When I went to pick up the vehicle. I was charged $155.00 for Customer request price on Motor Mount Replacement. Incredible. This gives new meaning to Stealership.

Troy is an awesome salesman there make sure to ask for him!!! He’s great respectful, honest and straight forward. He takes care of his clients and offers his absolute best service. Super hardworking. I’m happy with my new truck 👍

Do not purchase a car from Diamond Hills Auto. I purchased a 2020 buick encore GX and it only has 7000 miles on it. My check engine light has just come on for the third time in less than 2 months. The first time it came on I took it into the dealership and it was on the lot for 5 days before I was able to receive it back.After getting my car back and parking it in my driveway, oil leaked all over my driveway because the oil pan was damaged and/or not secure. I took it back to the dealership the next day and they had it for another 2 days. It took one week to receive my car back in working condition.About 3 weeks has passed since that occurred and my check engine light is on again. I spoke with Dave, the service manager, informed him how upset i was and his response was I do not have any openings today, i cannot even look at it today, and i have no loaner cars available. I was told not to worry about the check engine light because it was not blinking.So I should just tell my wife to drive herself and my 4 kids around in a car that has an active problem, because the light is not blinking? Well Dave, what happens when the light starts blinking and they are not in an area that is safe for a breakdown, or they are too far from home and now it needs to be towed?I will never purchase another vehicle from Diamond Hills again, I do not recommend their service department. You can see from other reviews that i speak very highly of those that do good work, this place is not one of those places.If i could give 0 stars, i definitely would

Fantastic service, and helpful staff. Relocated all service to Diamond Hills! Will be buying our next Chevy truck here. Rock n roll! 🤘😼🤘‼

Love this place!!Purchase my equinox there about a year ago, Gil was the person that helped me. I take my car there for service. Very kind, helpful and professional

Service department very courteous and professional. Best value of dealerships in the area for oil change and tire rotation. Awesome coupon deals.

Went to get my car service. And put a new transmission. In my car works great.

Sales man David was very helpful. Did not buy anything but greatly appreciate the help and service they offered. Respectful and friendly

Worst experience at a dealership. Salesman was not professional. He was lazy and very rude. Took long to get the keys and show truck. Soon as I got in he asked if I’m ready to sit and purchase. I told him I want to look at other options and I asked for his card all he did was reach over me and grab the keys locked it and walked away.

Second truck buying at from Diamond Hills Banning ca..👍✅

Great Dealership, great service for our 2020 Denali

Gary, Dante and Samantha are awesomeincluding the manager. They worked diligent with us thank you very much.. my son and his wife also bought a vehicle from diamond Hills awesome service...

Beware! Their advertised prices do not include a mandatory dealer prep fee of f $2,293. I set an appointment with Nathan to see a vehicle that was advertised at $34,497. I asked on the phone was that the price and he said yes that’s it so I came to see it. Once there I dealt with a salesman named Rick. I asked the total price of the car as I’m a cash buyer. Good luck getting them to disclose that hat to you early. They kept me there another two hours talking about financing, this incentive, that incentive and on and on. Adding up all the incentives which were supposedly another $1,400 off the $34,497 purchase price I was finally shown the price of the vehicle of $37,767 before taxes or something very close to that. This was for a vehicle advertised at $34,497. I asked how he came up with that number and after 2+ hours of waiting on him (which is of course a sales tactic) he said that the advertised price does not include “dealer installed options” of $2,293. Now he had told me earlier that the vehicle had not even been through dealer inspection so nothing had been done to it. I said then we’ll I don’t want the paint guard and whatever I’ll take it like it is. Nope they were going to put it on anyway. Super disappointed and I told them they were playing games and I left. This old school switcheroo tactic should be illegal in my opinion. You should be able to buy a vehicle at the advertised price. I would not waste my time here you will undoubtedly be fleeced one way or another. Typical shady car dealer.

Had everything nailed down with the salesman the VIN number of the truck the price and the interest rate to finance based on my beacon score of 820. Well guess what true to car dealerships nothing was the same. This dealership will tell you anything to get you in the door to get your money and nothing is the same when you get there. Was excellent credit they refused to honor the discounts and wanted 5% interest to finance. Even though their websites is 1.9% interest with good credit. Buyer beware!!! Dutton Buick GMC was bad, Diamond was the absolute worst!! I bought my truck at Hatfield Buick GMC in Redlands. Hatfield Buick GMC was courteous, straight forward, professional and fast!!! No funny stuff there!!

Customer service is horrible they do have a new service manager. And I really hope that he can make improvements. When I bought a vehicle from Diamond Hills I was treated like gold but after purchasing the vehicle it was like I didnt matter anymore. It pains me to say it but I thought I finally had found a dealership that not only cares about selling you a vehicle but also about taking care of the vehicle they sold you. At this point I think I was wrong

Samantha, Gary and Dante are awesome their team is great.. gave them a couple specifics they met my expectations 100% and quickly love my new car thank you Diamond Hills.

In and out in an hour. Had an oil change done and a recall. Nice relaxed atmosphere.

Each time I have bought my GMC Canyon pickup truck for maintenance service, I have been treated with the utmost respect and professionalism by the staff there. Thank you for keeping my wrap around insurance honored. Appreciate Mr. Rameriz help. Thank you, Claynette Ramsey

Great service and friendly staff.

I had a 12:00 appointment today to get my truck serviced and when I arrived just before 12:00 today they were closed.

I was lied to about my credit score! They owe me a check due to me having to pay for my own service they promised (company wont deal with them due to ugliness and lack of payment) excused me of wrong doing when I asked about the check Tried bribing me give them a good review...I should have known better then to buy anything from them their service dept sucks too. I cant get any help from any MAN there...Its just all bad right down to the greasy haired financial guy thinking he is slick.

There are couple people that act like thereto good to talk to you.

All the employees were very professional. They worked with me even when I didnt have a down payment! They took my car when it was working against me. Great guys!

I have not been to this dealer for good reason for years. Well tried to use them again to change my oil in my truck. I made a apt and was told it would only take a hour. I got to the dealer early they took the truck right in. After 2 hours truck is still not done. This is the reason i stopped years ago coming here is the SLOW services. I usually change my own and done in 30 min. never again just be warned
