Kestrel Take
A Tahoe with better trim and the same lifters. Denali models add magnetic ride control, which is excellent until a shock fails and you discover what magnetic dampers cost. Otherwise, the same known quantity.
Known Issues for the 2015 GMC Yukon
Ranked by wallet impact. These are documented, recurring problems — not freak accidents.
The defining GM V8 issue of this era. Ticking, misfires, and an engine teardown.
Repair cost range: $2,500-$5,000

The same GM dash cracking as the Tahoe and Silverado of this generation.
Repair cost range: $800-$1,600
Torque converter shudder on the 6L80/8L90, often improved by the updated fluid.
Repair cost range: $250-$3,500
