The above mentioned 2015 ford f150 platinum has since had the original problem, hard braking while passing a semi trailer while on the interstate at interstate speeds. This serious event happened oct 2, 2015. The recall did not fix the problem. The hard braking is a very sudden and serious event. It takes the truck from 70 to 55 or less MPH within the time it takes me to react and hit the gas pedal to stop the braking (1 second?).
