2025 GMC Sierra 2500hd

Compare 2 known trims and ownership for this model year, then open the exact trim and version when you want the details that change from one version to another.

2025 GMC Sierra 2500hd has 2 named trims in the lineup shown here: SLE and AT4.

The trim name matters because equipment, powertrain choices, capability and pricing can change as you move through the range.

Powertrain-specific details are still being filled in for this model year. AutoUnite leaves those numbers open rather than mixing different versions.

The feature census is not deep enough yet for a useful equipment summary. Missing equipment data is not treated as proof that the vehicle does or does not have a feature.

Package names currently documented include Gmc protection package, Preferred package, Snow plow prep camper package, Sle convenience package, Sierra hd pro safety plus package, and X31off road package. Package availability does not prove that a package is installed on a particular vehicle.

The Guide does not have enough applicable reliability evidence to support a pattern. That does not mean the model is problem-free; it means the available information is not strong enough for that conclusion.

Original manufacturer coverage shown here includes Basic: 3 years / 36,000 miles, Powertrain: 5 years / 60,000 miles, Roadside assistance: 5 years / 60,000 miles, and Corrosion perforation: 6 years / 100,000 miles. On a used or nearly new vehicle, remaining coverage depends on in-service date, mileage and eligibility.

The year-over-year record is not complete enough to say exactly what changed. A missing change record is not treated as proof that the vehicle carried over unchanged.
