NHTSA Complaint #11233255 — 2018 FORD F-150

I PURCHASED A NEW 2018 F-150 PLATINUM WITH HANKOOK DYNAPRO HTM 275/55/20 TIRES. AT 5,000 MILES THE REAR DRIVER TIRE DEVELOPED A BULGE IN THE SIDEWALL APPROXIMATELY 3 INCHES LONG AND 3/4 INCH WIDE FROM CENTER OF SIDEWALL TO THE TREAD. AT 7,500 MILES A SIMILAR BULGE DEVELOPED IN THE FRONT DRIVER TIRE. FRONTIER FORD IN SANTA CLARA, CA SERVICE DEPARTMENT TOLD ME TO CALL HANKOOK AND HANKOOK TOLD ME IT WAS THE DEALERS RESPONSIBILITY TO WARRANTY THE TIRE. THESE TIRES ARE DEFECTIVE AND UNSAFE TO DRIVE ON AND I NEED HELP TO GET SOMEONE TO TAKE ACTION. THERE ARE SEVERAL REPORTS ONLINE REGARDING HANKOOK TIRE SIDEWALL AND TREAD DEFECTS AND THIS TIRE NEEDS TO BE ADDED TO A RECALL LIST BEFORE IT CAUSES HARM. PICTURES AND SERVICE RECORDS CAN BE OBTAINED FROM FRONTIER FORD AND FORD MOTOR CORP CASE #CAS-22012913. IF YOU ARE EXPERIENCING A SIMILAR ISSUE WITH HANKOOK TIRES PLEASE REPORT YOUR CONCERNS TO HELP PREVENT THESE TIRES FROM CAUSING AN ACCIDENT OR REAL HARM. THANK YOU
