Used GMC cars for sale near Whitewater, CA

Great work Ryan! Very thorough in providing exceptional customer service thanks for resuming wash activities after the abundance of rain this season

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

My service advisor was Michael A. He did a tremendous job in explaining what was required at this service. He also gave me the upcoming services my vehicle will need in the future with estimated costs and approximate mileage markers of when each service should be done. Michael is very professional and friendly. On a scale of 1 to 10 with 10 being the highest I give him a 10+. The dealership is always very clean, and the waiting room is very comfortable.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Clay was the best salesman ever. Patient, knowledgeable, and informative! We can’t say enough. We did find the perfect car. There was no pressure. Go see him he’s a great guy.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Just want to thank Tom at Autosource in Banning California. Thank you for giving me a chance even with my low credit score. You never doubted that you would get me into my truck, thank you for giving me this opportunity! I'm a very happy girl. Buying this truck was so smooth hassle-free met with big smiles and welcoming personalities thanks again and see you I'll see you soon Stephanie Forrest

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Ramon was very busy but did a great job of getting the job done. He has great patience and knows his business very well. We’ll done!

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

I have never had the process of buying a car or truck be so absolutely painless as it was working with Steve Scott. Steve took care of me, found me and my wife exactly what we needed and didn't try to upsell me on features because he was clear on what we wanted and knew that that was the best way to keep us happy. I would 100% buy a car from Steve again. Roxanne worked with the finance department and with Steve to go ahead and make sure that our needs were met. We were treated respectfully, courteously, offered drinks and never talked down to or made to feel like we were being sold something we didn't want or need. I would absolutely buy from this dealer and from Steve.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Very easy paperwork and pleasant staff the sales lady Michelle was very helpful with the process also Gary the salesperson is a nice and will help out when needed

I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

Kayla was very helpful and informative about what was going on with my vehicle. Appreciate the updates always without having to ask what’s going on with my vehicle. Definitely will bring my vehicle back for service again.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Dominic and Alex were very helpful, took their time, honest about the vehicle, weren’t just trying to make a buck. Happy with the service provided, didn’t try tagging on extras, we asked about warranty and decided to buy it. Done deal.

Bought this 2016 GMC Canyon (4cyl) at car max in 2017 . It was part of a commercial fleet and was well taken care of and low mileage . I’ve only have had one problem and that was in the engine cooling system where I had to replace two hoses and a goose neck . While repairing that I noticed an oil leak around the valve cover so I replaced the gasket . It was under warranty still ( just happened in Jan 2024 ) . I could have repaired it myself but who wants to get all dirty when it can be repaired by GMC at little or no cost to me. It still has 6 months remaining on warranty ( I did purchase from CarMax) hoping it does not need any further repairs . It is 8 years old and according to its records this is the first repair other than natural repair items that had ever been needed . It rides well pulls my utility trailer fully loaded just fine . I also have a 2000 Ranger that I had to replace the tranny on when it was just a few years old . It has never needed any other work. I believe the GMC will last me for years to come . But you never know so I will be buying another after market warranty on it when the time comes . I’ve already added that to a 2015 vehicle I own who’s warranty had expired . I’m a old school mechanic I can repair olde vehicles easily ( compared to todays ) I’m also a former Turbo Prop Mechanic from the Air Force and worked those motors for almost 29 years . I had worked on Piston Air Craft Motors for a few years before the change . A lot like a car piston motor in many ways . Two kinds of piston motors on Air Craft . Line a cars block or a receptacating motor( Round) . Very easy to trouble shoot vs Turbo Prop. Just letting you know that I have experience as a mechanic and know a real problem vehicle when I see one . Would buy a GMC canyon again or maybe go larger due to my new 42 foot long Camper I have rec bought .

We've had only the best service with Diamond Hills. Everyone we have come in contact with over the last 2 years has been pleasant, courteous and helpful.

I love my new Hummer, I have had it 2 weeks now and it’s an Amazing vehicle. Looks great and is a lot of fun to drive. I love that I can take the 4 tops off and it’s a convertible suv. So far so good with no problems. It charges overnight and is ready to go. I would highly recommend.

Edgar was great. Knowledgeable, professional, and great communication. Ask for him at Jessup Auto Plaza! He took note of our needs and was not pushy by selling undesired inventory.

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

I didn't have an appt but they were awesome anyways. But nothing breaks on a schedule lol. I was helped quickly, offered coffee and a seat. They kept me updated on the car and how long it'd take for the parts. Thx guys, great job as usual.

I hade a Great experience at this dealership , Thank you Dylan for makeing my dreams come true. and to the finance depatment Freddy who made it very easy and fast, Icould not of had a better experience. I truly recommened Diamond Chevrolet Banning.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

Excelente purchased, thanks for been an excellent dealer , I will definitely recommend it. I’m excited to go back soon. My Toyota Tacoma 2021 is in a good condition and very low miles, thanks again

I bought my gmc canyon used with 29,300 miles on the odometer. It has the 2.8 ltr I-4 turbo diesel engine. I'm towing a 5,000 lb travel coach. First thousand miles was today. The small engine gets for me astounding fuel milage. Towing the coach i averaged 22. 8 mpg on a trip to the Eastern Sierras. 368 ft lbs of torque is more than enough to haul the trailer to 10,000 + ft elevation. Just be patient and use the torque to tow up a mountain. The fit and finish is excellent, the blue metallic paint turns heads. After 3 yrs a good waxing had it looking showroom new. This is my first gmc ever. If it holds up and runs 300,000 miles like the sales rep stated it's capable of doing. I'll let you know. The one down side is the emissions on the engine can cause reliability issues. Advice i found on a forum says use a good quality injection cleaner in every fill up . Every fill up for the life of the truck. They are capable 300,000 and higher if we'll cared for.

Performed service for Lo-jack and invisible bra. Was done earlier than expected. Service area was clean and efficient. Will take truck back again. Thank you for being so prompt.

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

As a woman making a vehicle purchase, I felt comfortable and not pressured. Edgar in the finance department was very helpful and made sure I understood all aspects of the contract.

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

Thank you Carlos Gonzalez and staff for working with us and providing us with extraordinary customer service. We’re very happy with our new GMC Sierra. My husband and I had been looking for a truck for months . Thank you for working with us.

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.

READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!
