Standard Sport Utility Vehicle 4WD
Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 3 tested variants for this model year.
The 2020 to 2024 GMC Yukon XL received a four-star overall rating from NHTSA's New Car Assessment Program for US-market vehicles. The model earned four stars in frontal crash protection and five stars in both side crash and side pole crash tests. Rollover protection received three stars. NHTSA applies these ratings across model years until a significant redesign occurs, so this assessment covers the entire 2020 to 2024 range.
4/5 Overall
NHTSA 5-Star Safety Rating
The 2024 GMC Yukon XL has 3 recalls, the most serious involving the transfer case and engine internals, both of which can cause sudden loss of control or engine failure while driving.
Vehicles equipped with four-wheel or all-wheel drive may experience front or rear wheel lockup through a defect in the transfer case, which can cause the vehicle to veer or skid without warning. On the engine side, this recall only affects models with the 6.2L V8: internal components including the connecting rod and crankshaft can fail, causing the engine to seize or shut down unexpectedly while the vehicle is in motion. The third recall involves the electronic brake control module software, which can fail to trigger a warning light when brake fluid drops to a low level. Without that alert, a driver may continue using the vehicle unaware that reduced fluid is gradually weakening brake response, leaving less stopping power available when it matters most.
