Can be triggered by an overpass, construction zones, truck in another lane, etc. Usually occurs on highways while at our top speed of 65 MPH. It will cause a hard brake down to 45 MPH. Can occur during night or daytime.”
NHTSA complaint #11112360, filed 2018-07, 238,380 miles“I started the truck after not driving for 1 day and a heavy rain storm the day prior. I attempted to drive bobtail when the brakes locked up. The traction control light came on then went back off. Then the adaptive cruise control notification came on. The regon came on then went back off. A speedometer sign with an exclamation mark came up and would not go away. After attempting to go down the road the brakes continued to lock up, would not release and caused the rear passenger tires to go bald and lose my job.”
