Horrible grinding noise low speed rotating of steering wheel. Sounds metal on metal grinding and clunking, dragging across ridged plate doing parking lot and backing maneuvers. Took to dealership. They said had no trouble codes, but does have internal failure of drive components noted. Scheduling for warranty replacement currently. Metal on metal grinding crunching noise. Entire steering rack needs replacement. Truck only has 79877 miles. It is definitely faulty. Other than that, awesome truck and love it. Everything else works perfect.

When the vehicle had less than 10,000 miles I brought it to the dealer to inspect the steering because of a binding/clunking noise while turning the steering wheel at a stop or slow speed. The dealership was unable to locate the noise at that time. Around 17.000 miles, the noise had gotten worse and they were able to locate it and replaced the steering box as well as the rack and pinion steering. Again, a little after 30,000 miles the noise was back but intermittent. The dealership did not hear it and said the steering was fine. Yesterday, with 40,000 miles, the dealership said the steering gear box needed to be replaced again as something is binding inside on the replacement steering box. Gm is denying this issue yet my research shows many people with the 2014 gmc sierra have or have had this problem. The one technician even told me his steering gear box on his 2014 1500 sierra had the same problem and compley failed. My research shows that this electronic gear box was introduced in 2014 and changed for a different steering box in 2015 models. An apparent acknowledgment of the problem.
