That thread was about an AWD drifting to the right. My 2012 R/T (RWD) has had zero problem traversing some really lousy streets with joints, cracks, repairs, etc. Zero problems, the steering is positive and never veers, swerves or even trammels. The OP's dealer is either a liar or an idiot, he needs to run away from the guy and try a different dealer. A Jeep dealer may work better and should still service the Durango, worth a try if there is one.
