We've just taken in a 2021 Chevrolet Suburban High Country SUV, finished in crisp Summit White with a Jet Black leather interior. This one-owner, full-size luxury SUV is in Good condition with 66,010 miles and comes backed by a dealership 1 month/1,000 mile powertrain warranty. With an impressive combination of space, technology, and capability, this Suburban High Country was built for families, adventurers, and anyone who wants comfort and confidence for every journey.
Power comes from a 3.0L Duramax Turbo-Diesel I6 engine delivering 277 horsepower and a massive 460 lb-ft of torqueâ"ideal for towing, highway cruising, or powering through unpredictable weather. Paired with a 10-speed automatic transmission and advanced 4WD system, it balances smooth acceleration with impressive efficiency, achieving up to 26 MPG on the highway. Whether youâre towing your boat to the lake or loading up for a cross-country road trip, the Suburbanâs commanding performance and composed ride make every mile effortless.
Inside, luxury meets practicality with three spacious rows of premium leather seating, including heated and ventilated front seats, heated second-row captainâs chairs, and a power-folding third row for flexible cargo and passenger space. The cabin feels open and refined, enhanced by soft-touch materials, bright trim accents, and an amazing view through large windows and panoramic sunroof. Tri-zone automatic climate control ensures everyoneâs comfort, while the heated steering wheel adds a touch of warmth and sophistication on cold mornings.
Technology is another highlight of the High Country trim. At the heart of the cabin is a 10.2-inch HD touchscreen with the Chevrolet Infotainment 3 Premium system featuring built-in navigation, Bluetooth, and wireless Apple CarPlay and Android Auto. A 15-inch color head-up display projects key information onto the windshield, while a 10-speaker Bose Surround Sound system fills the cabin with crisp, immersive audio. Thereâs also a rear camera mirror for a wide-angle view behind the vehicle, a wireless charging pad, and multiple USB ports to keep everyone connected on the go.
Safety and peace of mind come standard. This Suburban is equipped with an advanced suite of driver-assistance features, including Forward Collision Alert, Automatic Emergency Braking, Lane Keep Assist, Lane Departure Warning, Blind Spot Monitoring, and Rear Cross-Traffic Alert. The HD Surround Vision camera and adaptive headlights make maneuvering this full-size SUV easier and safer, whether youâre in a tight parking lot or reversing with a trailer attached.
From the outside, the Suburban High Country commands attention. Its chrome accents, bold grille, 22-inch premium alloy wheels with chrome inserts, and LED lighting signature give it a refined, confident look. Power-retractable running boards and a hands-free power liftgate with emblem projection add modern convenience to its robust design. With a towing package, heavy-duty locking rear differential, and adjustable suspension system, this SUV delivers capability that matches its luxury.
Slide behind the wheel, and youâll feel a perfect blend of power, control, and sophistication. Every detail of the 2021 Suburban High Country is engineered to elevate your driving experienceâ"whether itâs the quiet hum of the turbo-diesel engine, the precision of the steering, or the serenity of the Bose audio system. Itâs more than just transportation; itâs a command center for your familyâs adventures.

Comfortable land yacht. Drives smaller than it is.
By Cmoney56 | on Friday, February 12, 2021
5.3L offers adequate power and the new independent rear suspension coupled with magnetic ride control provides for the smoothest riding Suburban, too date. New styling is bold and aggressive. Love the look and sound of the split dual exhaust. Interior is much improved over past generation and push/pull button shift is a nice touch that is easy to get used to. The power folding 3 and 2 row seats are a nice touch and sliding second row are a great added feature. The headrests on the 3rd row are a known problem and if you have a 2021 Suburban or Tahoe, you will likely have an issue with one or both of the headrests not staying up. Overall a refreshing and much needed update. Like the inclusion of diesel to the line up, as well.… - 4.0
Third One
By Art | on Saturday, February 12, 2022
I have owned two Tahoe SUV's a 2007 & 2011. I purchased my 2021 Suburban which is just a bigger Tahoe in September 2021. I wanted a Tahoe, but the shortage issues put me in a suburban. I loved my 2007- Z71 and let it go at 80,000 miles to buy my 2011-LTZ. Which I still own, and it has 195,000 miles on it. The only problem with my 2011 was a bad Torque converter which I caught very early and saved my Transmission. My 2007 had the same problem and it took out the Trans. All was covered by warranty. The only other issues were a cracking dash which chevy pretty much covered. Other than that, it was just normal maintenance. So, I took the leap and bought another because over all these trucks have been awesome. The key to the mileage is service. I was a mechanic in the Army and service my vehicles early and often. I have been under my new 2021 and it doesn't look as heavy duty as my 2007 or 2011. But it is built the same V8 rear wheel drive on frame. Framed vehicles are much safer and hold up better in my opinion. I have put 5500 miles on the truck and the only issue I have had is the third-row seat belt beauty bracket in the headliner was broken when installed. Other than that, no issues. I believe the quality is there and don't expect any issues after looking it over. What I don't not like about the vehicle is the lack of a key (push button start) and the buttons instead of a shift lever to put the vehicle in drive / reverse. I am keeping my finger crossed but expect this will be problem points later when the vehicle ages. I am hoping for another 200,000 miles out of this truck, time will tell. As far as comfort these trucks are like riding in your living room. I love them.… - 5.0
Wow, super upgrades, incredible ride!
By dc Zman | on Sunday, May 18, 2025
OK, so I have owned 2 previous suburbans (2002 & 2013), so the 25 is an amazing upgrade to both of these! First of all, we do a lot of highway miles and the ride is simply amazing! It rides more like a luxury sedan than a truck. Since this is our primary vacation vehicle, we were careful to order 18 inch wheels, as they have a much smoother ride versus the larger ones. I also love all of the new cameras, which is a big help in tight situations. Also, the adaptive cruise control and lane assist make long road trips easier and safer as well. I also love the new exterior design features, particularly the front grill and the aerodynamic wings on either side of the rear window. I'm a bit surprised that those small design features have really updated and enhanced the look so much. The only real disappointment, so far, is the owners manual was really poorly done. Information is difficult to find, nonexistent and they even neglected to put in the required scheduled maintenance requirements (what were they thinking?). Overall, our first impressions on this vehicle have been superb and I would definitely recommend it to others who need a large family/vacation vehicle!…
