Frequently Asked Questions
What is the GMC factory warranty?▼
GMC's factory warranty is 3 years/36,000 miles bumper-to-bumper and 5 years/60,000 miles powertrain (engine, transmission, drive axles, transfer case). GMC also provides 5 years/60,000 miles roadside assistance. These are the same terms as Chevrolet — both are GM brands sharing the same warranty program. Buick and Cadillac receive longer coverage: 4-year/50,000-mile bumper-to-bumper and 6-year/70,000-mile powertrain.
Can I buy a GMC extended warranty online?▼
Yes — both GMC's factory-backed Protection Plan and third-party extended warranties can be purchased online. GMC's dealer program requires visiting or contacting an authorized GMC dealer. Third-party providers allow full online purchase, instant quote comparison, and coverage that begins after a short waiting period (typically 30 days or 1,000 miles). Buying online from a third party often costs 25-40% less than the same coverage from a GMC dealer.
What is the GMC Protection Plan?▼
The GMC Protection Plan is GM's factory-backed extended warranty sold through GMC dealerships. It offers three main tiers: Powertrain (engine and transmission), Major Guard (major systems), and Bumper-to-Bumper (near-comprehensive). It is the same program as Chevrolet Protection Plan with different branding. Dealer pricing for Bumper-to-Bumper typically runs $1,800-$3,800 as a lump sum. Third-party providers offer equivalent coverage for less with monthly payment options.
What happened to Suzuki extended warranty?▼
Suzuki exited the US automotive market in 2012 after filing for Chapter 11 bankruptcy protection for its American operations. Suzuki's factory warranty obligations for vehicles sold before the exit were honored through American Suzuki Motor Corporation's wind-down. There is no longer a Suzuki dealer network in the US for factory warranty service. Suzuki owners who purchased vehicles before 2012 have seen their factory warranties expire, but third-party extended warranty providers do cover Suzuki vehicles on the used market, providing continued protection for owners of well-maintained Suzuki cars and SUVs.
What are common GMC Sierra and Yukon problems?▼
Common GMC Sierra and Yukon problems include: 5.3L and 6.2L V8 AFM (Active Fuel Management) lifter failures ($2,000-$4,500), 10-speed transmission shudder (2019-2022 models), 6L50/6L80 six-speed transmission issues on older models, AC compressor failures above 80,000 miles, infotainment and wireless module failures, oil consumption on the 5.3L, and air suspension failures on Denali trim trucks with the air-leveling system.
How much does a GMC Sierra extended warranty cost?▼
Third-party extended warranty for a GMC Sierra 1500 under 80,000 miles runs $110-$155/month for mid-tier coverage, or $145-$195/month for exclusionary. For the Yukon and Yukon XL under 80,000 miles, expect $130-$175/month mid-tier and $165-$220/month exclusionary. GMC dealer Protection Plan pricing for the Sierra runs $2,200-$4,000 as a one-time premium for equivalent 3-year coverage.
