What changed on the 2027 GMC Sierra EV?

GMC’s 2027 starting prices are higher on all three trims: the Elevation starts at $63,400 (2026: $62,400), the Denali at $78,700 (2026: $69,700) and the AT4 at $80,100 (2026: $79,300) (GMC, 2027). The EPA rates the 2027 Extended Range truck with the 11kW charger at 396 miles of range and 66 MPGe combined, against 410 miles and 68 MPGe for the 2026 (EPA, 2027).

What warranty covered the 2026 GMC Sierra EV?

The Sierra EV’s propulsion battery is covered for 8 years or 100,000 miles, whichever comes first, under GMC’s published 2026 model-year terms (GMC Electric Vehicle Limited Warranty and Owner Assistance Information, 2025). The vehicle itself is covered by a limited warranty against defects in materials and workmanship, for a shorter period than the battery.

The basic limited warranty runs 3 years or 36,000 miles, whichever comes first, and covers the complete vehicle for repairs to correct defects in materials or workmanship (GMC Electric Vehicle Limited Warranty and Owner Assistance Information, 2025). Items listed under What Is Covered and What Is Not Covered in GMC’s document change that coverage, so check those lists before you rely on it.

If the battery’s capacity falls below 75% of its original value during the warranty period, GMC replaces or repairs it. A certified dealer makes that call and uses a battery suited to the vehicle’s age and mileage (GMC Electric Vehicle Limited Warranty and Owner Assistance Information, 2025).

Under the California ZEV warranty, GMC also covers the battery against defects that drop its state of health below 70% for 8 years or 100,000 miles, whichever occurs first (GMC Electric Vehicle Limited Warranty and Owner Assistance Information, 2025).

GMC’s powertrain coverage is typically 5 years or 60,000 miles, and its corrosion coverage is typically 3 years or 36,000 miles, whichever comes first in each case. GMC notes other durations are available (GMC’s warranty protection page).

The Internal Revenue Service says the federal New Clean Vehicle Credit and Previously-Owned Clean Vehicle Credit have ended and are not available for vehicles acquired after September 30, 2025 (Internal Revenue Service, 2026). A new or used EV bought today does not qualify for either credit.

What does Texas charge to register an electric vehicle?

Fully electric cars and trucks rated at 10,000 pounds gross vehicle weight or less pay an annual $200 fee when registration is renewed.

Standard registration fees still apply, and the fee does not apply to hybrid vehicles (Texas Department of Motor Vehicles, 2026).
