Bought my 2016 GMC Sierra 2500 HD diesel crew cab 4x4 in July after retiring the same truck (2007 1/2, new body style) with 267,000 miles and never a problem (still has original brakes). Put 15,000 highway miles on my new truck, various trips, TX to CO twice for scouting/hunting elk, fly fishing here/there with pleasure/ease - this thing is cadillac! On a short trip (180 miles) to do some deer scouting in TX I noticed slack (lash) in my steering. Heading home the next day and the lash had increased to 3-4 inches before the wheels would take up and turn from left to right. WTF? Brand new truck? Contacted the dealer when I got home, service department said don't drive the truck - call roadside assistance and have it towed in. Dealer had if for a day and made the repair. Nut on top of steering box had backed off - they tightened, retorqued (with red permatex) and called it good. Steering back to tite as new, but we'll see. Geez.
