Having an ongoing issue while driving. I've ben on the highway in the rain and snow going 65-70 mph as well as dry pavement. All of a sudden my dashboard will light up saying service traction control, brake system, abs , park assist off and check engine lights up and blinks . I will loose my brakes I then have to pump my brakes several times to get to even slow down or stop . It's also happened when I am driving down a residential street. When I pull over turn the truck off and goes back to normal for a short distance. Weather doesn't seem to be a factor or speed. Taken vehicle to dealership and they don't find anything wrong. Had them replace bearings as well as speed sensors and it is still happening. And I had a code come up for cylinder misfire and knock sensor. Then take it garage and nothing is wrong.
