12-25-2016 after drooping off maid and gardener here in huatulco mexico my power steering quit. since going so slow down hill on village street i thought that motor had quit. realized that motor was running. then noticed dash warning that said hill descent control fault, power steering assist fault, service advance track . called dealer that we bought truck from they told me there was a computer update needed for truck. not to happy since i had told dealer when truck was in shop that we drive 2850 miles to our home in huatulco mexico each year and that i was in hutulco. had local dealer look at. local dealer now tells me that truck needs power steering column and that he did put in service update also blinker will not stay on unless held down
