Rack and Pinion failed on me at 99k miles. I just got done with my workout and went to go start up the truck and the service power steering message came on with the power steering indicator light. That wheel would hardly move when I tried to move. I also decided to look under the truck and under the hood for any leaks and nothing and then soon realized after doing a quick google search that the 2013 and up models are electric power assist instead of hydraulic. The truck was towed next day to the dealer and they quoted $3600 to replace the rack and pinion.
