2014 GMC Sierra 1500 body & structure problems

My vehicle has side board steps. The tread pattern is such that when wet or icy the step is a virtual skid pad. When you place weight on the foot on the tread it immediately slips out from under your position. Last year I broke a foot when I slipped and this year it was an ankle. Tread design needs to be improved and turned 90. As designed there is no traction protection. Just the opposite, it promotes lack of traction resulting in slipping and falling.

Tl* the contact owns a 2014 GMC sierra 1500. The contact stated that the vehicle was taken to an independent body shop to have some damages repaired. The contact was advised that the frame underneath the vehicle was rusted. The dealer (anchor buick GMC, 1 automotive blvd, elkton, md 2192) was contacted and stated that there was a technical service bulletin for the failure; however, the vehicle was no longer under warranty due to high mileage. The vehicle was not repaired.
