I was driving from lufkin to hemphill at 70 mph. Something blew up, I thought something hit me. Engine died, brakes started, emergency lights came on, and seatbelt locked down, truck stopped, I got out to see what hit me. Nothing! when I got back in the truck a white powder (not smoke) was coming out of the seat belt on drivers side. When seat belt locked down I had to back seat up to get out of the belt. I was lucky that I did not hit someone.

In cold weather, the brakes may stay engaged, even upon releasing the brake pedal. This will happen sporadically, and usually upon starting for the first time at a given day. I will start driving, then brake when required, release the brake when I want to resume driving, but the brakes may remain engaged.
