I have a 2009 Sierra Denali with 155k miles. Once it rolled 100k, it started becoming a bit of a money pit...
Had to replace control arms, ball joints, front hubs/bearings, brakes, front differential, a front axle halfshaft. Not a fan of the AWD system - lots more moving parts that wear out, and the front diff is pricier than the standard 4x4 front diff.
If you're considering the purchase, I'd suggest a prepurchase inspection at an independent/reputable mechanic.
