Mile ratingKnown issues to check on the 2017 GMC Yukon XL
One widely reported problem pattern applies to this model year. That does not mean this car has the fault — many were fixed under warranty or recall — but it is what to check, and what to ask the seller for, before you buy.
- 8-speed automatic transmissionWorth checking
The 8L90/8L45 eight-speed is widely reported to shudder and clunk on light throttle — the well-known "Chevy shake" — traced largely to the torque converter and transmission fluid.
What to check: Drive at 25–50 mph on light throttle and feel for a vibration through the floor. Ask whether the torque converter was replaced or the fluid changed to the revised Mobil 1 spec.
Patterns are drawn from NHTSA recalls and complaints, manufacturer service bulletins and consistent owner reporting. Always confirm open recalls against the VIN and get an independent pre-purchase inspection.

The verdict
The 2017 GMC Yukon XL Denali 4WD is listed at $20,950 with 119,000 miles. The Caboose score is 8.0 out of 10, built from three things: how far below market the price sits, how much of the 200,000-mile target is still ahead of the odometer, and how often this model reaches 250,000 miles in the iSeeCars study (8.6% of GMC Yukon XLs do).
The asking price is $2,848 (12.0%) under the CarGurus expected price of $23,798, which is a real discount rather than a rounding gap. That puts it in the top group of cars on this site, so it is worth a same-week inspection before someone else books one.
