Pros

  • 328-hp turbo engine is stronger than most rivals' base powertrain
  • Denali/Denali Ultimate trims add genuine luxury-tier features and materials
  • AT4 trim offers a more off-road-styled 3-row option than most rivals

Cons

  • RepairPal ranks it 23rd of 26 midsize SUVs, with a 19% severe-repair rate — well above the class average
  • iSeeCars shows steep 5-year depreciation (52.4%)
  • Shares its platform and reliability pattern with the similarly low-scoring Chevrolet Traverse
  • 21-23 mpg combined trails most 3-row hybrid/efficient rivals

Can this car reach 300,000 miles?

Unlikely

RepairPal's model-specific score (3.0/5.0) ranks the Acadia 23rd of 26 midsize SUVs, with a 19% severe-repair probability — well above the 13% class average. It shares its turbo-4 platform and general reliability pattern with the similarly low-scoring Chevrolet Traverse.

First-Time Buyer Friendly

48/100

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

60,000 miles

Brake pads
Higher-than-average odds of a repair being severe by this point, per RepairPal's data

100,000 miles

Spark plugs and turbo engine components

150,000 miles

Suspension bushings and shocks, more so under 3-row-hauling loads

200,000+ miles

No strong track record at this mileage; near-bottom-of-class RepairPal ranking suggests budgeting well above a Highlander/Telluride/Santa Fe rival for unscheduled repairs

What It Actually Costs to Own

One of the more expensive 3-row crossovers on this site to actually own — above-average repair costs stack on top of steep depreciation, similar to its Chevrolet Traverse platform-mate.

Estimated Annual Fuel Cost$1,820
Estimated Annual Insurance$1,550
Estimated Annual Maintenance$500
Estimated Annual Repairs$734
Estimated Annual Registration$210
