occasionally the last couple of weeks, i will be driving the truck and the tow/haul feature will come on by itself!. i hit the button and it goes off. it may come back on a minute or two later or may be not- until days later. throwing no codes! any thoughts? thanks.

 

Sounds like a chaffed wire somewhere in the steering column.. Just a guess tho

 

**** that would suck! i was hoping it would be simpler-like a switch/solenoid or sensor down on the tranny.
