The 2021 Chevrolet Silverado 2500 HD is a formidable heavy-duty pickup truck, part of Chevrolet's fifth generation Silverado HD line introduced for the 2020 model year. Available in Regular Cab, Double Cab, and Crew Cab body styles, key trims include WT, Custom, LT, LTZ, and the luxurious High Country. New prices ranged from approximately $36,000 to over $70,000. It stands out for its exceptional towing and hauling capabilities, powerful engine options, and robust work-oriented design, making it a popular choice for serious truck users.
The Good
The 2021 Silverado 2500 HD offers immense towing and hauling performance, particularly with the Duramax diesel, appealing to practical buyers needing serious work capability. Its bold design, spacious interior, and available creature comforts also provide emotional appeal. While not "efficient" in a traditional sense, its robust reliability and strong resale value offer excellent long-term practicality and value.
The Bad
Watch out for its notably firm ride quality when unloaded, which can be less comfortable for daily driving. Its large dimensions make urban maneuvering challenging, and the gas engine's fuel economy can be quite poor. Some interior plastics might feel less premium than rivals, especially in lower trims.

What Problems Does the 2021 Chevrolet Silverado 2500 Have?
The 2021 Chevrolet Silverado 2500 HD, being part of the updated generation introduced in 2020, has generally shown solid reliability, particularly its renowned 6.6L Duramax diesel engine and Allison 10-speed transmission. However, like any vehicle, some issues have been reported.
Frequently Reported Problems:
Recalls:
The 2021 Silverado 2500 HD has had several recalls issued by NHTSA, which are important for potential buyers to check if addressed. These include:
When considering a used 2021 model, it is crucial to verify that all applicable recalls have been completed by a certified dealership to ensure safety and proper functionality.
Frequently Reported Problems:
- Infotainment System Glitches: Some owners have noted occasional freezing, lag, or connectivity issues with the MyLink infotainment system, though often resolvable with software updates.
- Transmission Shifting Concerns (Gas V8): While the Duramax's Allison transmission is robust, the 6-speed automatic paired with the 6.6L gas V8 has had isolated reports of harsh shifting or hesitant gear changes, though not widespread.
- Brake System Wear: Due to the truck's weight and common use for heavy hauling, brake components (pads and rotors) may experience faster wear than in lighter vehicles, requiring more frequent inspection and replacement.
- Steering System Noises: A few owners have reported minor creaks or groans from the steering system, particularly at low speeds or when turning, which usually points to minor lubrication issues or worn bushings.
- Emission System Components (Diesel): Diesel particulate filters (DPF) and Selective Catalytic Reduction (SCR) systems, while vital for emissions, can be prone to issues if the truck isn't driven enough to allow proper regeneration cycles, leading to potential warning lights or reduced performance. This is common across modern diesels.
Recalls:
The 2021 Silverado 2500 HD has had several recalls issued by NHTSA, which are important for potential buyers to check if addressed. These include:
- Fuel Pump Module: A recall (NHTSA Campaign Number 21V630000) for certain diesel models where the fuel pump module could fail, potentially leading to an engine stall.
- Power Steering Assist: A recall (NHTSA Campaign Number 21V111000) for an issue that could cause intermittent or complete loss of power steering assist.
- Air Bag System: Recalls related to potential issues with the air bag sensing and diagnostic module (NHTSA Campaign Number 21V726000) or incomplete deployment of the passenger frontal air bag.
When considering a used 2021 model, it is crucial to verify that all applicable recalls have been completed by a certified dealership to ensure safety and proper functionality.
How long will the 2021 Chevrolet Silverado 2500 last?
With proper maintenance, the 2021 Chevrolet Silverado 2500 HD is built for long-term durability, often reaching 200,000 to 300,000 miles or more, equating to 15-20 years of service for average drivers. The Duramax diesel engine is particularly renowned for its longevity. However, heavy use, especially consistent towing at maximum capacity, can accelerate wear on suspension components, brakes, and tires. Over time, expect potential for electrical gremlins with age, and the emission systems on diesel models may require attention. Consistent fluid changes, filter replacements, and addressing minor issues promptly are crucial for maximizing its lifespan and reliability, making it a strong long-term investment for those who need its capabilities.

2021 Chevrolet Silverado 2500 Prices and Market Value
When new, the 2021 Chevrolet Silverado 2500 HD ranged from approximately $36,000 for a base WT Regular Cab 2WD to over $70,000 for a fully-loaded High Country Crew Cab 4WD. As of early 2024, used market prices typically range from $38,000 to $65,000+, heavily dependent on mileage, trim, engine (diesel models command a premium), condition, and regional demand. Heavy-duty trucks generally depreciate slower than light-duty trucks and passenger cars due to their utility and longer expected lifespan. Factors positively affecting resale value include the powerful Duramax diesel engine, 4WD, higher trim levels (LTZ, High Country), low mileage, a clean maintenance history, and the inclusion of advanced trailering and safety packages. Conversely, high mileage, basic trims, and significant wear and tear will negatively impact its value.
2021 Chevrolet Silverado 2500 Cost of Ownership
Owning a 2021 Chevrolet Silverado 2500 HD is generally costly. Insurance premiums are higher due to its size, power, and repair costs. Fuel costs are significant, especially with the 6.6L gas V8, often seeing 10-14 MPG. The Duramax diesel improves mileage but requires more expensive diesel fuel and Diesel Exhaust Fluid (DEF). Maintenance is also pricier; larger tires, brakes, and specialized diesel service add to regular costs. Repairs, when needed, involve more robust and expensive parts. Long-term ownership is therefore on the higher end of the spectrum. This is not an economical vehicle to own, but its high utility justifies the cost for those who truly need its capabilities.

How Does the 2021 Chevrolet Silverado 2500 Compare to Other Truck?
The 2021 Chevrolet Silverado 2500 HD competes fiercely against the Ford F-250 Super Duty and the Ram 2500 Heavy Duty, forming the "Big Three" in the segment.
Performance:
The Silverado's 6.6L Duramax diesel (445 hp, 910 lb-ft) and Allison 10-speed transmission offer outstanding towing and hauling, often praised for its smooth power delivery. The Ford F-250's 6.7L Power Stroke diesel (475 hp, 1050 lb-ft) boasts higher figures, making it a slight leader in raw capability for some configurations. The Ram 2500's 6.7L Cummins diesel (370 hp, 850 lb-ft or High Output 400 hp, 1000 lb-ft) is also a strong contender, known for its longevity. All three are incredibly capable, with choice often coming down to brand loyalty or specific payload/towing needs.
Features:
The Silverado 2500 excels with its available 15-camera trailering system, offering unparalleled visibility for towing. Its infotainment system is user-friendly, though some interior plastics, especially in lower trims, might feel less refined than the Ram. The Ram 2500 is often considered the segment leader for interior luxury and ride comfort (thanks to its coil-spring or optional air suspension). The Ford F-250 offers robust work-oriented features and an intuitive infotainment system, balancing utility and comfort well.
Reliability:
All three have strong reputations, particularly their diesel engines. The Duramax and Cummins are celebrated for their long-term durability, while the Power Stroke also stands strong. General reliability for heavy-duty trucks tends to be high, assuming proper maintenance, as they are built for demanding tasks. Recalls and minor issues can occur across all brands.
Price:
Pricing across these heavy-duty trucks is competitive, with base models starting in the high $30,000s to low $40,000s and fully-loaded top trims easily exceeding $70,000. Used market values are strong for all, with diesel engines generally holding their value better.

- If ultimate towing capacity is paramount: Consider the Ford F-250/F-350 Super Duty.
- If luxury interior and ride comfort are top priorities: The Ram 2500 HD is a strong contender.
- If a balanced approach to towing tech, power, and traditional truck feel is desired: The 2021 Silverado 2500 HD remains an excellent and highly recommended choice, especially for those who appreciate its unique camera system and powerful Duramax engine.
Final Verdict: Is the 2021 Chevrolet Silverado 2500 a Good Truck?
The 2021 Chevrolet Silverado 2500 HD is ideal for individuals and businesses requiring serious towing and hauling capabilities, such as contractors, farmers, or those frequently towing large RVs or trailers. It's a worthwhile purchase if its heavy-duty capacity genuinely aligns with your needs, as its robustness comes with higher operating costs.
Buying used, particularly a Duramax-equipped model, often provides excellent value, as depreciation has already occurred, yet the truck retains much of its capability and longevity. For those prioritizing luxury and advanced tech, the LTZ or High Country trims offer a comfortable and feature-rich experience. If the primary goal is raw work utility, a WT or LT trim with the Duramax is a pragmatic choice. However, if you don't regularly haul heavy loads, a light-duty truck would be more economical and comfortable.
