250KMile ratingKnown issues to check on the 2018 GMC Yukon
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.
