The all-new 2019 GMC Sierra 1500 introduced the T1XX platform, 5.3L or 6.2L V8s with Dynamic Fuel Management, and new eight- or 10-speed automatics. At 80,000–100,000 miles, DFM lifter and 10-speed shudder repairs deserve attention.

Known Issues on the 2019 GMC Sierra 1500
DFM Lifter Failure and Oil Consumption
Dynamic Fuel Management lifters can fail in a manner similar to earlier AFM systems, causing a tick, misfire, or oil consumption. Lifter replacement and related repairs cost $2,500–$5,000.
Aggregated owner forums, TSB discussions, and NHTSA complaint records for 2019 Sierra V8s repeatedly cite ticking, misfires, and oil-use reports associated with cylinder-deactivation lifter concerns.
10L80 Light-Throttle Shudder
On 6.2L trucks, owners report shudder and shift quality concerns with the 10-speed. A rebuild if calibration or fluid work is insufficient can cost $3,500–$6,500.
MultiPro Tailgate Mechanism Issues
The new MultiPro tailgate's latches and powered components can require adjustment or replacement. These smaller repairs commonly total $200–$600.
