problem #1

Dec 262016

Yukon Denali 6.0L

  • Automatic transmission
  • 84,500 miles

I started having issues on dry pavement while accelerating very gently from a stop. The Yukon will hesitate due to the brakes being applied by the traction control. The "Traction Control Active" message displays on the instrument cluster. Releasing the accelerator or tapping the brake pedal seem to help it stop.

I took it to the dealership. They told me that the Brake control module was not communicating correctly. There was significant corrosion on the control module as well as the Control Valve assembly so both were replaced. After replacing one DOA control module, we seemed to have it corrected... for about 1 day.

Then the symptom came back.

I asked about Wheel bearings,Wheel Speed sensors, electrical ground connections all of which I was assured were OK. The dealership has not been able to diagnose the issue even after communicating with the engineers at GM (that is at least what I was told)

I am currently waiting to see how this plays out.

I will update when I have a resolution.
