“The component that is failing is the frame. The vehicle is available for inspection upon request. The safety of myself and others is at risk due to the frame falling apart due to the lack of integrity. The lack of integrity and strength is from oxidation or major rust. The vehicle has not been inspection by a 3rd party. The rust is a common issue in this year/model from other owners and has appeared to be a manufacturing error.”
“The frame above the RT rear tire has rusted completely through. It's where the rear end bolts to the frame, at a wedge welded to the frame with bolt holes in it. It's like it wants to flip over and darts left or right every time there's a dip or rough spot in the road. I chained it and put a tow strap around everything I could to keep the rear end from coming out & killing me or someone behind me”
“I BOUGHT THIS TIRE FROM A FIRESTONE COMPANY. I WAS DRIVING ON THE I-60 EAST COMING FROM WORK. ALL OF A SUDDEN I HEARD A LOUD NOISE AND IMMEDIATELY MY CAR STARTED TO SHAKE VIOLENTLY. IT WENT OUT OF CONTROL, STIRRED TO THE LEFT AND HIT THE HIGHWAY SEPARATOR (A CONCRETE ROAD BLOCK). THE FRONT OF MY CAR DIRECTLY WENT CRASH INTO THAT CONCRETE BARRIER IN A PERPENDICULAR POSITION, MAKING A FULL FRONTAL CONTACT, THAT RELEASE BOTH FRONT AIRBAGS. MY WINDSHIELD CRACKED AND MY FRONT CAR AREA IS TOTALED. I CAME OUT OF THERE WITH NECK, HEAD, BACK AND CHEST INJURY. *TR”
