CarGurus Analysis: 2018 GMC Sierra 2500HD
Summary
With 569 currently listed for sale and an average price of $39,658.00, 27.9% of 2018 GMC Sierra 2500HDs for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 GMC Sierra 2500HD 3.8 / 5 stars.
68.0% of 2018 Sierra 2500HD models on CarGurus are accident free.
Why it stands out
The 2018 GMC Sierra 2500HD stands out as a heavy-duty pickup that blends work-truck capability with a more upscale feel than many rivals. It sits in a lineup that offers a wide range of trims and configurations, and GMC gives it a broader spread of upscale options and features than the related Chevrolet Silverado 2500HD. That makes it appealing to buyers who want a truck that can handle serious duty but still feel well equipped inside.
For 2018, the Sierra 2500HD could be had with a 6.6-liter V8 gas engine paired with a six-speed automatic transmission, or with a 6.6-liter Duramax turbodiesel V8 and a 10-speed automatic transmission from Allison. Rear- and four-wheel drive were available, and the truck could be configured as a Regular Cab, Crew Cab, or Double Cab with 7' or 8'2" cargo beds. Available equipment included Bluetooth, Android Auto, Apple CarPlay, and wifi hotspot accessibility, while higher trims could add features such as a Bose Premium audio system, power-adjustable front seats, chrome grille trim, dual-zone automatic climate control, and a power-folding tailgate option.
That breadth of equipment is part of the Sierra 2500HD’s appeal, especially for shoppers who want a heavy-duty truck that feels more polished than basic. At the same time, used buyers should be aware that these trucks can be expensive, and the model line has known issues that include check engine lights, infotainment sluggishness, rough or delayed shifts, electrical glitches, MultiPro tailgate problems, and faulty trailer brake controllers.

Entire undercarriage is covered in rust. All control arms and linkages are in extremely poor condition from rust to the point I wouldn’t feel safe driving it. Let alone using it for its intended purpose for heavy duty towing.

Powerful, dependable, quiet interior and looks great! The duramax with the Alison transmission is the best diesel on market!
