GMC has built trucks and full-size SUVs that define American utility. The Sierra 1500 is one of the most capable half-ton trucks on the market, the Yukon and Yukon XL are premium full-size SUVs with genuine towing capability, and the Terrain and Acadia give you crossover versatility. But the same engineering that makes GMC vehicles dependable workhorse tools also makes them expensive to repair when key components wear out.
The most common failure point on GMC's 5.3L V8 EcoTec3 engine is the Active Fuel Management (AFM) system — specifically the lifter and camshaft follower components that allow cylinder deactivation for fuel economy. AFM lifter collapse is a well-documented issue on Sierra, Yukon, and Yukon XL models built between 2007 and 2023. The repair involves removing the intake manifold and replacing all 16 lifters and related hardware — it's a $3,000–$6,000 job at most shops. GMC's factory warranty covers 3 years/36,000 miles bumper-to-bumper and 5 years/60,000 miles on the powertrain. For a Sierra or Yukon with 80,000 miles, that warranty is long gone.
Priority Auto Protection gives GMC owners a flexible alternative to the GM Protection Plan's dealer-only, multi-year commitment model. Month-to-month coverage from $99/mo — cancel anytime, use any licensed shop nationwide. Whether you drive a Sierra 1500 crew cab, a loaded Yukon Denali, or a Terrain you bought used, check your eligibility free in under two minutes.

Every GMC model has its quirks. Here's what owners commonly report — and what coverage tier protects you.
Not every GMC needs the same coverage. Here's how to choose based on your model, mileage, and driving habits.
Covers the 5.3L or 6.2L engine internals, transmission, transfer case, and drivetrain. Protects against the most expensive GMC repairs — AFM lifter failure and transmission issues — at the lowest monthly cost. Best for owners who want core protection without paying for electrical and A/C coverage.
The most popular tier for Sierra and Yukon owners. Adds A/C compressor, electrical systems, power accessories, and steering to the powertrain base. Covers the AFM system, 10-speed transmission, A/C, and power running boards — the full suite of common GMC failure points.
Adds suspension components (air suspension on Yukon), advanced electrical systems, and broader factory technology coverage. Right for owners of premium trim levels where component costs are significantly higher — a Yukon Denali air suspension compressor can cost $1,200+ to replace.
Near-bumper-to-bumper coverage including infotainment, navigation, advanced driver assistance systems, and factory-installed technology. Best for 2018–2023 Sierra or Yukon models with lower mileage where breadth of coverage matters and you want the closest thing to the original factory warranty.
