Pros

  • RepairPal ranks it 6th of 14 fullsize SUVs, with below-average repair costs for the segment
  • Up to 8,400 lbs towing and 122.8 cu ft of maximum cargo space
  • Denali/Denali Ultimate trims offer genuine luxury-SUV features
  • Full Chevy/GM Safety Assist suite standard across the lineup

Cons

  • Shares the 5.3L/6.2L V8 engines under active NHTSA investigation for valve-lifter failures (~877,700 vehicles) with the Silverado 1500 and Sierra 1500
  • iSeeCars shows steep 5-year depreciation (53.3%) despite the solid reliability ranking
  • Starting price is among the highest of any non-luxury-badged SUV in this research
  • Fuel costs are among the highest of any non-truck vehicle reviewed on this site

Can this car reach 300,000 miles?

Likely

RepairPal's model-specific score (3.5/5.0) ranks the Yukon a solid 6th of 14 fullsize SUVs, with below-average repair costs for the segment. The main caveat: the Yukon uses the same GM 5.3L/6.2L V8 engines that are under an active NHTSA investigation for valve-lifter failures, shared with the Silverado 1500 and Sierra 1500.

First-Time Buyer Friendly

35/100

Livable, but the complexity or running costs here reward buyers who already have some ownership experience.

Reliability Timeline

What tends to need attention, and when — based on model-specific reliability data.

RoutineModerateMajor

30,000 miles

Oil changes, tire rotations
Watch for check-engine lights, misfires, or ticking/tapping noises — early signs of the documented valve-lifter issue on the 5.3L/6.2L V8

60,000 miles

Brake pads and rotors
Transmission fluid service

100,000 miles

Spark plugs

150,000 miles

Suspension and air-ride components on equipped trims, more so under heavy towing/hauling use

200,000+ miles

Engines that avoid lifter failure commonly run well past this mileage with routine upkeep

What It Actually Costs to Own

A solid class-relative repair-cost position is offset by steep depreciation and the same active lifter-failure investigation affecting its Silverado/Sierra platform-mates — budget for higher fuel costs too, given the size and weight.

Estimated Annual Fuel Cost$2,450
Estimated Annual Insurance$1,750
Estimated Annual Maintenance$570
Estimated Annual Repairs$747
Estimated Annual Registration$250
5-Year Depreciation~53% of purchase price

Check for open recalls before you buy

We don't yet have a live recall feed wired up for the GMC Yukon, so we won't guess at a number here. Before you buy any specific Yukon, run its VIN throughNHTSA's free recall lookup tool— it takes about 30 seconds and confirms whether that exact vehicle has any open, unrepaired safety recalls.
