2022 GMC Sierra 1500 Model Year Overview
The 2022 Sierra combines truck capability with advanced powertrain and tailgate systems. While lower mileage helps, owners approaching the 60,000-mile powertrain limit should understand the vehicle's known DFM, transmission, and diesel-service risks.
Known Issues on the 2022 GMC Sierra 1500
DFM Lifter Failure Risk
DFM lifters can still collapse, creating a tick, rough running, or oil consumption in affected V8s. Repairs that replace lifters and address collateral wear generally cost $2,500–$5,000.
Owner-forum observations, GM TSB references, and NHTSA-style complaint records show that ticking and misfire reports remain useful warning signs for DFM-equipped 2022 Sierra V8 owners.
10-Speed Light-Throttle Shudder
The 6.2L/10L80 combination can exhibit shudder or hard shifts under light acceleration. If a major internal repair is needed, costs can be $3,500–$6,500.
Duramax DEF and Glow Plug Repairs
Diesel models may experience DEF-system warning messages or glow-plug faults. Diagnosis and component replacement normally cost $600–$1,500.
