Missing a few things that could really make it better.
Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

I have loved and owned Chevy and GMC midsized trucks
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.

Rafeal was my contact there and he was great.
Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork
So far the car is going great.

Great Diesel truck when emission sensors work
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.

Leon and Max were great to work with and made our deal
Leon and Max were great to work with and made our deal come together when I wasn’t sure they could get to our number. The highlight was when we came to pick it up and the car had been detailed beautifully - it was spotless. I would recommend them without hesitation.
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Safest Vehicle I've Owned
I bought a 2016 Yukon XL and after just a few weeks, a vehicle ran a stop sign and totaled the vehicle. However, the vehicle was so sturdy that even though it was a huge crash, I was not injured more than bruises. I replaced it with a 2018 Yukon XL because I know it is reliable and safe.

Good, but did not buy
We did not buy from them. The one year old car with 30,000+ miles on it was priced above the norm, even by Kelley Blue Book standards. No negotiations available. So didn't buy. Nothing more. I'd recommend people to try, it doesn't hurt. But just be weary, you lose 3 years worth of manufacturer warranty, in just one year. Buying process, quality of repairs, facilities rated 3's, because it wouldn't submit as "n/a". So these are not a true rating. Wanted to rate "n/a".

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

Sold my car to Autonation.
Sold my car to Autonation. It was an extra, so we weren't replacing it. Of course, a dealer paid wasn't great. But Chris Corringan was great to work with. He did exactly what he said he would do, WITHOUT any bait-and-switch tactics. When we're in the market for another car, we'll definitely give them a first try.
Excellent vehicle. Very comfortabe and reliable
This vehicle fits all my needs. Powerful enough to pull my 32 ft travel trailer - excellent powerful engine and engine brakes kicking in on downhill slopes

Honest Guy
Fira was very professional and honest and worked with me to get me the best deal possible. I was happy with my experience at Sams and the price It was nice to deal with him.
Newest & Biggest SUV I've ever owned
The styling looks great outside & everything functions as it should. It has loads of options, heated & cooled seats & steering wheel, very cold air, big comfy 7 seats. While not a luxury-looking plush interior, it is very nice. A couple pieces of plastic molding inside are loose, a back panel I tried to take off & the visor mirror on drivers side. I've owned this for 6 months & adore it! Very roomy.

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

Mile High Made It Happen!
We purchased a 2019 ILX with the exceptional help of Matt Heintz. We had been car shopping all day and the staff at Mile High didn’t waste our time...they cut straight to the bottom line and made it extremely apparent they wanted our business. Matt and his team had us in and out in under 30 minutes. Hard to say about any other dealership. Highly recommend purchasing your next vehicle here!
a great Truck
I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!
