So I am currently on vacation 300 miles from home. My truck is a 16 1500 Z71 and has about 33000 miles on it and all of the sudden driving on a flat surface grade braking will enable. The truck is also shifting randomly and violently. Sometimes when making turns in auto mode it will feel as though the 4wd system is engaged. Anyone else encounter these issues? Anyone might know what could wrong that I can fix real quick while I'm away?
