U.S. model years 2021–2026
GMC factory warranty
GMC factory-warranty guide for U.S. MY2021–MY2026. No exact-year, brand-wide baseline term is retained. Scope-limited overlays are retained separately for MY2026 heavy-duty overlay for powertrain and MY2026 named-model overlay for new-vehicle, powertrain, surface-corrosion, corrosion-perforation, and roadside-assistance. Official route: gmc.com / Account warranty.

Historical changes
Each MY2021–MY2026 entry is an exact-year record for GMC. There is no retained exact-year, brand-wide baseline term. Scoped material appears only as MY2026 heavy-duty overlay for powertrain and MY2026 named-model overlay for new-vehicle, powertrain, surface-corrosion, corrosion-perforation, and roadside-assistance. No displayed term is carried to an adjacent model year, another propulsion type, or a different named-vehicle scope.

Program structure
GMC is presented as nine distinct factory-warranty or benefit categories for each exact model year. No exact-year, brand-wide baseline term is retained. Scope-limited overlays are retained separately for MY2026 heavy-duty overlay for powertrain and MY2026 named-model overlay for new-vehicle, powertrain, surface-corrosion, corrosion-perforation, and roadside-assistance. Retained affirmative source records use official manufacturer web page evidence. The guide records an exact official locator: Build & Price summary; selected state: 2026 Sierra 2500 HD Pro RWD, Crew Cab/Standard Bed; Warranty section; Powertrain/Drivetrain Limited Warranty card; exception line: 3.0L & 6.6L Duramax Turbo-Diesel engines and certain commercial, government, and qualified fleet vehicles: 5 years/100,000 miles.

Separate benefits
For GMC, roadside-assistance terms are retained only in MY2026 named-model overlay; no affirmative included-maintenance term is retained. Those entries are displayed as separate benefits, not warranty-repair conclusions; every other roadside or maintenance cell remains unverified.

Vehicle-specific verification
For a vehicle-specific determination, use the recorded GMC official route: Sign into myGMC, select the vehicle, then Warranty icon/Warranty Tracker; retrieve documents by model year/make/model in GM Manuals and Guides. Then compare the VIN-specific record with the original model-year material before relying on an unverified cell or a scoped overlay.

Factory warranty and service-contract overlap
The Federal Trade Commission distinguishes the manufacturer warranty included with a new vehicle from an optional separately purchased auto service contract. For GMC, this guide displays scope-limited overlays only (MY2026 heavy-duty overlay for powertrain and MY2026 named-model overlay for new-vehicle, powertrain, surface-corrosion, corrosion-perforation, and roadside-assistance). Compare a proposed contract only against the displayed terms and VIN-specific record; do not broaden an unverified cell or scope-limited overlay.
