If you read the TSB, it mentions that the software needs to be updated for the electronic steering. THIS is what I've been trying to tell guys for two full years now. My JL was HORRIBLE and after they totally reinstalled and updated the vehicle calibrations in the software, INSTANTLY it went to normal. Drove great after that. NO hard parts replaced. This was Jeep's first go at electronically controlling a solid axle steering system. It had some early bugs. Nobody gave it a chance and started throwing hard parts at it instead! Bad move!
