NHTSA Complaint #10949567 — 2015 FREIGHTLINER CASCADIA

WIPER RESERVOIR BECOMES HEATED DUE TO DPF SYSTEM WHICH CREATES PRESSURE WITHIN THE SYSTEM. AS A RESULT IT FORCES WIPER FLUID FROM THE NOZZLES DRAINING THE SYSTEM MOST TIMES UNDETECTED. RESULTING IN THE INABILITY TO CLEAN THE WINDOW WHEN IT BECOMES FOULED. DUE TO THE RESERVOIR BOTTLES LOCATION YOU CANNOT OBSERVE THE FLUID LEVEL THIS IS ALSO HINDERED DUE TO THE PLASTIC BECOMING STAINED BLUE BY THE WIPER FLUID OVER TIME. THERE IS ALSO NO INDICATOR THAT WIPER FLUID LEVEL IS LOW FROM WITHIN THE CAB. THIS OCCURS BOTH WHEN THE VEHICLE IS IN MOTION OR STOPPED WHEN THE VEHICLE PERFORMS A "REGENERATION" OF THE DPF SYSTEM.
