NHTSA Complaint #11397365 — 2018 FORD F-150

WINDSHIELD FLUID IS FREEZING UP. 1ST TIME I THOUGHT IT WAS BECAUSE THE FLUID USED WAS ONLY FOR WARMER TEMPS AS THERE WAS ALSO SOME ICE FLOATING IN THE RESERVOIR BB. TOOK TO A DEALER IN NY, HAD THE OLD FLUID REMOVED & REPLACED WITH FLUID GOOD TO -20 DEGREES. IT WORKED FINE AT FIRST AFTER REPAIR BUT THEN OVERNIGHT IT FROZE AGAIN IN THE LINES (NOT RESERVOIR). IT EVENTUALLY DEFROSTED IN SOUTHERN VIRGINIA, AFTER DRIVING @6 HOURS. LUCKILY THE ROADS WERE RELATIVELY DRY. I'VE LIVED IN COLD CLIMATES THE MAJORITY OF MY LIFE NEVER HAVE EXPERIENCED THIS. I FOUND INFO ON YOU TUBE THAT ONE OF THE VALVES NEEDS TO BE ENLARGED TO PREVENT FREEZING.
