How much does the 2019 GMC Sierra 2500HD cost?

Prices have softened 7.48% compared to this time last year, making it a favorable time to shop this model year.

With 863 listings available, you have a solid pool of trucks to compare across trims, mileage, and condition.

If you find a listing below $39,685.49, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2019 GMC Sierra 2500HD a good car?

Yes — the 5/5 user rating points to strong owner satisfaction, and this model year is aimed at buyers who want heavy-duty capability with a more upscale feel than many rivals. The Sierra 2500HD also offers a broader range of upscale trims than the related Silverado 2500HD, which makes it especially appealing if you want a work truck that feels more polished inside. Its available tech and utility features add to that appeal if you want a truck that can handle both job-site duty and everyday use. 26.2% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2019 GMC Sierra 2500HD reliable?

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

The overview also points to a truck that can be appealing for its capability and upscale presentation, but it flags several issues you should take seriously on the used market, including check engine lights, infotainment sluggishness, rough or delayed shifts, electrical glitches, MultiPro tailgate problems, and faulty trailer brake controllers. That means reliability can depend heavily on how well a specific truck was maintained and whether known trouble spots were addressed. For used buyers, the main long-term ownership risk is ending up with a high-cost repair truck if you skip a careful inspection.

What should I look for when buying a used 2019 GMC Sierra 2500HD?

At 70.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. Put inspection priority on the diesel emissions system, infotainment behavior, shifting quality, electrical operation, and trailer-brake functionality. Because this truck can be expensive to fix, condition matters more than chasing the lowest sticker price.

Is now a good time to buy a used 2019 GMC Sierra 2500HD?

This looks like a moderate, selective buyer's market, so you can shop patiently and still find worthwhile options.

• Deal availability: 26.2% of listings are priced as good or great deals.
• Inventory: There are 863 listings available.
• Price trend: Prices have softened 7.48% compared with last year.
• Clean inventory: 70.6% of listings are accident-free.

If you find a listing below $39,685.49, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2019 GMC Sierra 2500HD's resale value?

The current average of $39,674 sits slightly below last year's $42,883.

That softer pricing suggests the market has become more favorable for buyers, but it also means future sellers may need to price competitively to move a truck quickly. If you buy well now and keep the truck in strong condition, you can help protect your exit value later. Trucks with cleaner histories and fewer unresolved issues tend to hold buyer interest better in this segment.

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

Should I buy a 2019 GMC Sierra 2500HD or consider a different year?

If you're weighing the 2019 against nearby model years, here's how to think about it:

Choose the 2019 if:

• 26.2% of listings are priced as good or great deals.
• At 70.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.48% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2020 if:

• At $49,100, the 2020 costs more than the current year's $39,674 average.
• It adds a more luxury-leaning Denali identity with a stronger premium focus.

The bottom line: If you want the better value play, the 2019 is the smarter starting point because it combines a lower average price with meaningful inventory and deal availability. If you care more about a newer, more premium-feeling truck and are willing to pay up, the 2020 is the secondary path to consider.
