A new tsb came out today for those with the thud or bump in the steering wheel. It requires replacing the intermediate shaft. I already had mine replaced a couple weeks ago and it took care of the problem.
Does it feel like a little looseness in the steering/small movement?
Yes it feels like someting is loose and a thud in the wheel when braking and making parking lot turns. Replacing the shaft on mine took care of the issue even though mine probably did not get this new part number.
