Used GMC Sierra 1500 Denali for sale near Montclair, CA

My service manager, Tony Hang, is the best and he is the reason I continue to go to Crown Lexus Of Ontario. I I am always able to make appointments however I always ask for him. If he is not there, I tend to wait until he is. He is very professional yet makes me feel very comfortable. If Tony is busy when I call, he always returns my calls in a timely manner. I have absolutely no complaints about Lexus and I think Tony is a great asset to your dealership. Please feel free to contact me if you have any questions.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

The service staff were friendly and efficient. My car was serviced (oil changed and tires rotated) and ready in a timely manner. The waiting area and rest room were clean

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. :)

Excellent service every time I come here. Jaime Nava is great to work with and provides excellent customer service.

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!

Sales personnel knowledgeable and helpful. Not close by but would definitely discuss a car purchase soon.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Peter and Jorge were excellent to work with. They made the buying process enjoyable. Very professional and treated us like family! I would definitely buy here again!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

My truck was service and clean in the time promised. The service advisor are allows courtesy and helpful. The dealership and waiting area is clean and easy to assets

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

“The entire car-buying process was smooth, efficient, and genuinely professional. From the initial inquiry to driving off the lot, every step was handled with clarity and care. The staff provided prompt updates, transparent information, and a streamlined workflow that made the experience stress-free. Overall, it was a well-organized and highly satisfying purchase.

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.

muy buen servicio, kris me atendio consegui la gmc muy buen trato me hiso lo recomiendo

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!

Alex G is probably the most helpful car salesman there is. Not only did he make sure to really do everything he could to get me a great deal on a car I actually wanted, but as a first time car buyer no other dealership or car salesman wanted to seriously help me, but he did. I can’t recommend Alex enough at this dealership.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Albert was great in assisting me with my new Tesla! Couldn’t have asked for better service.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

good buying experience on our 2021 Mazda 6 touring. good test drive with good explanations on all the good technology this car has to offer. was recently in to service, made a appointment. everything good, all questions answered. I was treated well.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Pretty great experience overall. My sales representatives Maria and Rene were very helpful, answered all my questions and made the whole transaction quick. Highly recommend STG Auto!

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Was ok but car sold 1 day before I was scheduled to go in and purchase

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.
