Is the 2021 Chevrolet Silverado 3500HD a good car?

Is the 2021 Chevrolet Silverado 3500HD reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The Silverado 3500HD is described as a heavy-duty truck that can handle demanding towing and hauling while still serving everyday needs, which points to a design focused on durability and utility. Its powertrains are built for serious work, and the truck’s easy-to-use technology and broad configuration range support long-term usefulness.

The 6.6-liter gas V8 and available Duramax turbodiesel V8 both make strong power, and the diesel’s 10-speed automatic helps keep it in the ideal gear for optimal performance. The truck also comes with a five-year, 60,000-mile powertrain warranty, which adds some ownership reassurance.

If you plan to keep one long term, the biggest risk is buying a truck that has been worked hard without proper maintenance or inspection.

What should I look for when buying a used 2021 Chevrolet Silverado 3500HD?

Accident-free inventory is solid at 79.5% — always verify the vehicle history report.

You should start with a history report and then prioritize a close inspection of the truck’s condition, especially if it has been used for towing or hauling. Pay attention to visibility-related concerns, cabin wear, and whether the equipment on the truck matches the listing.

Key things to evaluate:

• Trim level: The W/T comes with two USB ports, vinyl seat trim, two-tier trailering mirrors, and a 7-inch touchscreen with Apple CarPlay and Android Auto. The LT adds cloth seating, body-color door handles, Chevy’s EZ lift-and-lower tailgate, a 4.2-inch driver information display, an integrated trailer brake controller, a 4G LTE WiFi hotspot, and an 8-inch touchscreen. The LTZ adds chrome exterior accents, leather upholstery, heated front seats, remote start, dual-zone automatic climate control, 120-volt wall-style power outlets, and side mirrors that extend and have integrated turn signals. The High Country adds heated and ventilated front seats, chrome side steps, a Bose premium sound system, and a spray-in bed-liner.
• Powertrain: There are two engines: a standard 6.6-liter V8 with 401 horsepower and 464 pound-feet of torque, and an optional Duramax turbodiesel 6.6-liter V8 with 445 hp and 910 lb-ft of torque. Both powertrains can be paired with rear-wheel drive or available four-wheel drive with low range, and the diesel’s 10-speed automatic helps keep it in the ideal gear for optimal performance.
• Safety package: The truck comes standard with a backup camera and a full array of front- and side-impact airbags. Forward collision avoidance, lane-departure warning, automatic emergency braking, automatic high beams, blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, and a 360-degree parking camera system are available, so you should confirm which items are actually fitted on the truck you’re considering.
• Infotainment: The standard setup is a 7-inch touchscreen, while upgraded trims get an 8-inch touchscreen and the High Country adds navigation. The system is described as easy to use and benefits from hard buttons and dials, plus a helpful home button.
• Fuel efficiency: Drivers can expect fuel economy between 12 and 15 mpg.

Which 2021 Chevrolet Silverado 3500HD trim should I buy?

The 2021 Chevrolet Silverado 3500HD is offered in 4 trim levels: W/T, LT, LTZ, and High Country.

Here's the short version:

• W/T: This is the work-focused starting point, with vinyl seat trim, two USB ports, two-tier trailering mirrors, and a 7-inch touchscreen with Apple CarPlay and Android Auto. It makes sense if you want the Silverado 3500HD’s core capability without paying for extra comfort features.
• LT: This is the best-value trim for many buyers because it adds cloth seating, the EZ lift-and-lower tailgate, an integrated trailer brake controller, a 4G LTE WiFi hotspot, and an 8-inch touchscreen. It gives you a more useful and more comfortable truck without jumping too far up the price ladder.
• LTZ: This trim adds leather upholstery, heated front seats, remote start, dual-zone automatic climate control, chrome exterior accents, and extended mirrors with integrated turn signals. It’s the right step up if you want more comfort and trailering convenience.
• High Country: This is the luxury-oriented choice, with heated and ventilated front seats, chrome side steps, a Bose premium sound system, spray-in bed-liner, and navigation. It suits you best if you want the most upscale version of the truck.

For safety, the truck comes standard with a backup camera and a full array of front- and side-impact airbags, while many driver-assistance features remain optional.

Is now a good time to buy a used 2021 Chevrolet Silverado 3500HD?

This is a moderate market for selective buyers, so it pays to compare listings carefully and move quickly on the right truck.

• Deal availability: 30.1% of listings are priced as good or great deals.
• Inventory: There are 989 listings available.
• Price trend: Prices have softened 4.00% compared with last year.

If you find a listing below $46,747, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Chevrolet Silverado 3500HD's resale value?

The current average of $47,103 sits slightly below last year's $49,064.

That decline suggests the market has eased a bit, which can help you as a buyer today but may temper what you can expect on a future trade-in. The current pricing also sits within a fairly tight year-round range, which points to a truck whose value is being shaped by steady demand rather than dramatic swings.

If you buy well and keep the truck in strong condition, you should be able to preserve more of its value over time. Heavy-duty trucks with broad usefulness and strong capability tend to stay relevant with shoppers who need real towing and hauling strength.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Chevrolet Silverado 3500HD safe?

It earns an 8/10 safety score from our experts.

The Silverado comes standard with a backup camera and a full array of front- and side-impact airbags. For safety features such as forward collision avoidance, lane-departure warning, automatic emergency braking, automatic high beams, blind-spot monitoring, and rear cross-traffic alert, you’ll have to pay extra.

You’ll also have to shell out for the front and rear parking sensors and a 360-degree parking camera system, which are especially helpful given the truck’s size. That means you should pay close attention to the exact safety equipment on any used example you’re considering.

Should I buy a 2021 Chevrolet Silverado 3500HD or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 30.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79.5% — always verify the vehicle history report.
• Price trend: Prices have softened 4.00% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 model combines heavy-duty towing strength with everyday usability, easy-to-use technology, and plenty of cargo space.

The bottom line: If you want a heavy-duty truck that balances serious capability with everyday livability, the 2021 Silverado 3500HD is the primary year to target. If your priority is simply finding the lowest price, you can also compare nearby model years and focus on the truck with the best equipment, condition, and history rather than the badge year alone.
