Power Steering system failure warning message followed by a Stabilitrac system failure warning which caused the drivers front side brake to apply. I could not duplicate the brake application issue with the dealer but the other failures which included loss of power steering at highway speeds and lack of stabilitrac system was repeatable. A full replacement of power steering rack was performed with a front end alignment after dealing with the problem for weeks. Was told this manufacturing failure was covered for free in models newer and older than my truck (same model) but my truck was not covered. This is unsafe and not acceptable.
