Unexplained Sudden Acceleration
By emzomarja on


2009 GMC Yukon XL SLT2 1500 4dr SUV 4WD (5.3L 8cyl 6A)


Purchased our vehicle new in 2009.
Generally satisfied with the SUV.
In December 2012 the vehicle unexpectedly accelerated without explanation.
The car was towed to dealer - who could not re-create the defect.
The vehicle has a bulletin out on a throttle defect but claim that it is due to a loss of power rather than a sudden acceleration. The manufacturer declined to pay for the cost of analysis of the defect, in spite of the throttle bulletin indicating they will pay the cost of the repair.
Have 75K mi. on car but now wrestling with keeping it due to the concern.
Expected another 2 years out of the vehicle, especially at this price for car - but now may have to find another option.
