The bottom line
Don't buy the clean paint job. Repaints are common here but no worse than the wider used fleet, and structural repairs stay rare, so body history is not the Yukon problem. The engine is. Fuel trim out of range shows up on 56% of these trucks, oil leaks sit right behind it, and active electronic codes are nearly as common. Scan it and look for wet oil before you negotiate. Tires and shocks wear out often enough to knock the price down, not to scare you off by themselves. Walk if the same truck has bad trim, leaking oil, and live codes together — that stack is the deal-breaker, not a bargaining chip.
