NHTSA Complaint #10240471 — 2008 FOUR WINDS PRESIDIO 400

I OWN A 2008 PRESIDIO 400 MOTORHOME BUILT BY MANDALAY. THE WIPER SYSTEM ON MY MOTORHOME HAS NOT WORKED SINCE THE FIRST TIME I TRIED TO USE THEM. AT A SPEED OF 60 - 65 MPH, THE PASSENGER BLADE TRAVELS TO FAR TO THE DRIVERS SIDE AND LOCKS UP WITH THE DRIVERS SIDE WIPER AND THEY BOTH CEASE TO WORK. I HAVE TAKEN THE MOTORHOME INTO THE DEALERSHIP TWICE AND TO THE MANDALAY SERVICE CENTER IN ELKHART, IN. ONCE AND THE SYSTEM IS STILL NOT WORKING CORRECTLY. THE DEALERSHIP TRIED ADJUSTING THE SYSTEM, DID NOT REPLACE ANY PARTS. THE MANDALAY SERVICE CENTER TRIED TO REPLACE THE 2008 WIPER ARM AND BLADE THAT CAME ON THE MOTORHOME WITH THE 09 WIPER ARM AND BLADE, AND THIS DID NOT WORK. NOW THEY FEEL THAT THE WIPER ARM "ACORN" WAS NOT SEATED CORRECTLY AND THEY ARE SENDING ME NEW ACORNS TO REPLACE THOSE I HAVE. I FEEL THAT THIS SITUATION IS A SERIOUS SAFETY CONCERN. HOW CAN I CONTINUE TO DRIVE THIS MOTORHOME DOWN THE ROAD IF I DO NOT KNOW IF THE WIPER SYSTEM IS GOING TO WORK OR NOT!! I GUESS I DON'T THINK MANDALAY FEELS THE SAME WAY ABOUT THIS SITUATION. *TR
