2022 GMC Sierra SLT 3.0 Duramax
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!

I bought this after going to the dealer just to look at
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.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Maria Sanchez, Christian Campos and Sales Manager Rene
Maria Sanchez, Christian Campos and Sales Manager Rene were nothing but exceptional in the process of purchasing my vehicle. With the exception of a couple of other factors that weren’t pleasing, but these 3 individuals made it all worth while and a great car buying experience. Thank you!
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

EASY Carbuying experience, great service dept!
I bought a 2004 Pilot a month ago here. My salesman, Tim, knew exactly which loan to submit me for because I had no job and bad credit but a big down payment. He had me financed with no problem in minutes. A few days before I went to Carmax Burbank for a different car but with the same down payment and the saleswoman there did not do the same thing. The car was purchased in 2 hours and I was driving home. I bought the warranty tey offer which is a great bumper to bumper extended through their company. They have a 5 day return policy. I opted to return my car on day 4 to pay for the warranty in cash so as not to finance it at the very high interest rate I bought the car at. The return was also easy and everything was done in less than an hour. A month later now, I have found a few things wrong with this 2004 that seemed to have slipped past their extensive reconditioning program. I took it in with odd complaints a dealer would normally say they couldn't duplicate. They addressed them all and even gave me a loaner SUV for my babies to fit in while I waited the few days for the parts to arrive. GREAT STORE! Great customer service! And there's a play room for the kids! *Avoid the coffee!! It is terrible!!!
Pleased that I made this purchase
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.

2019 Sierra SLT X31
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

Adam did a nice job locating the vehicle I wanted to see.
Adam did a nice job locating the vehicle I wanted to see. He went the extra mile tracking down the service manager, beginning the purchasing process, and ultimately ensuring the vehicle was ready for pick-up a week later. I found Adam to genuinely care that I had a good purchasing experience.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Like the truck but also disappointed
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" GMC Truck!
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.
