Severity: medium.

What is the 2015-2020 GMC Yukon MyLink / IntelliLink 8-Inch Touchscreen Failure?

The 8-inch MyLink/IntelliLink infotainment touchscreen (RPO IO5/IO6) develops ghost touches where it presses buttons by itself, dead zones that stop responding, and delamination/bubbling where the digitizer separates from the LCD. Because so many K2XX Yukons share this radio, it… Repairs typically run $150-$600. Severity: low.

What is the 2007-2014 GMC Yukon HVAC Blend Door Actuator Failure (Clicking Behind Dash)?

The small electric blend-door actuators that control temperature and air-flow direction strip their internal plastic gears, producing a repetitive tapping/clicking noise from behind the radio or glovebox and causing the HVAC to blow the wrong temperature (e.g., stuck cold on the… Repairs typically run $60-$500. Severity: low.

What is the 2000-2006 GMC Yukon Intermediate Steering Shaft Clunk / Pop?

A hallmark GMT800 complaint: a clunk or knock felt in the steering wheel and column when turning at low speed or driving over small bumps and rough pavement.
