how do you know that it got disengaged? is the traction control light on? if so, the traction control computer may have detected a fault and turned off traction control as a fail-safe way to drive.
"Traction Control Disengaged" appeared on the instrumentation panel above the steering wheel. It just appeared one day while I was driving.
do you have any ck eng or trac lights on?
