Summary:

The 2006 GMC Yukon, while generally reliable, can suffer from common issues related to engine oil consumption and lifter tick, especially in the 5.3L V8 engines. Transmission problems such as harsh shifting and torque converter failure with the 4L60E are also relatively frequent. Suspension issues, particularly with the Autoride system, and electrical problems like instrument cluster and door lock actuator failures, can add to the ownership costs. Severity ranges from minor inconveniences like AC actuator clicks to major repairs like engine or transmission replacement. The cost of repairs can range from a few hundred dollars to several thousand, depending on the issue and the extent of the damage.
