2005 LINCOLN AVIATOR Structure Problems

I HAVE A LINCOLN AVIATOR AND FORD REFUSES TO FIX THE LIFTJAR CRACK IN THE BACK IT IS A CONCERN SINCE THERE IS SO MUCH RAIN IN FLORIDA HOW DO I KNOW WHAT LEAKS IN THERE AND ITS THEIR DEFECT JUST BECAUSE ITS NOT A SAFETY ISSUE DOESN'T MEAN THEY SHOULDN'T HONOR THE FIX ITS RIDICULOUS I MADE NUMEROUS CALLS AS WELL AS A DEALERSHIP TRYING TO HELP ME OUT BUT FORD REFUSED. *TR

A VERTICAL CRACK ON PLASTIC COVERING OF HATCH COVER. STARTS AT THE LINCOLN MEDALLION THAT IS CUT INTO THE PLASTIC PIECE AND EXTENDS VERTICALLY TO BOTTOM EDGE. I TOOK IT TO A LINCOLN DEALER. ESTIMATE WAS $500 FOR A PIECE OF PLASTIC THAT MEASURES APPROXIMATELY 12 INCHES HIGH AND THE WIDTH OF THE HATCH DOOR. THIS IS DEFINITELY A DESIGN ERROR ON THE PART OF FORD. THE SERVICE MANAGER TOLD ME THAT HE SEES A LOT OF THIS SAME COMPLAINT AND IT IS NOT COVERED BY FORD. A $42,500 AUTOMOBILE WITH A DEFECT IN DESIGN THAT RESULTS IN AN UNSIGHTLY SPLIT IN PLASTIC PIECE WANTING AN OUTRAGEOUS FEE OF $500 TO REPLACE THE PIECE. DO YOU THINK I WILL EVER BY ANOTHER FORD PRODUCT. NOT IN THIS LIFETIME! THANKS FORD WHO ALWAYS PUTS QUALITY FIRST. *TR
