Water leak issue coming from the windshield and cowl area leaking into the passenger side compartment shorting out the Smart junction box causing the gauges and all electrical to go haywire such as the headlight to go out while driving and the traction control to turn off as well as the windows and power locks to quit working and could cause an electrical fire inside the care if gone un noticed. I have the vehicle in the shop and this is going to cost me $600 or more due to Fords knowing of an issue they will not own up to fix to ensure safety.
