Yup, my 2014 TH AWD just 💩 the bed!I got the W47 recall notice in the mail for my '15 TH and had the programming update done @ the dealership where I bought it. I agree with the OP as now I have a 4X4 BUT if the splines do sheer off I will only have a RWD Trailhawk. Unacceptable.
FCA should have to restore their vehicles to the original status they were when purchased. Their defect.
After 5 Jeeps over a 25+ year period, this could be the end of that.
They flashed software still got message to service AWD! Need to replace PTU for big $$$!! Car drives fine but no more AWD!
