Recommended Plan for GMC Sierra 1500
Based on typical Sierra 1500 repair patterns and costs
The Sierra's AFM lifter failure is the most catastrophic and expensive engine issue, and the 8L90 transmission has known reliability concerns. Deluxe Coverage protects the engine internals (including lifters), transmission, A/C, fuel delivery, and 4WD drivetrain — the systems most likely to cause expensive repairs on a Sierra.

GMC Sierra 1500 Extended Warranty FAQ
New GMC Sierra 1500s include a 3-year/36,000-mile bumper-to-bumper warranty and a 5-year/100,000-mile powertrain warranty. Once factory coverage ends, repair costs — including AFM lifter failures — are entirely your responsibility.
Active Fuel Management (AFM) — used on Sierra 5.3L and 6.2L V8 engines — deactivates cylinders to improve fuel economy. A known design flaw causes the AFM lifters to collapse, leading to engine knocking and requiring lifter replacement or a full engine rebuild costing $2,500–$5,000.
Most GMC Sierra 1500s with a clean title and under 150,000 miles at enrollment are eligible. This includes GMT800 (1999–2006), GMT900 (2007–2013), K2 (2014–2018), and T1 (2019–present) generations. Call us with your VIN for a specific eligibility check.
