    No accident happened. I purchased a motorhome had two new tires steering tires 315 8022 five size tires when they hot driving is a tremendous shake to the front end and I’ve had it back to the tire company and nobody seems to want to do anything to help me? I think it’s a bad safety issue you could lose control of the motorhome. It’s 45 foot And the brand of the tire is. Yokohama I have filed a complaint with him. They have no one seems they won’t call me back. She told me to go to some dealer and I talked to the dealer and the dealer says no we don’t undo it. I don’t know what their problem is, but I think this is a tremendous safety issue you get a semi or a motorhome like I got always 45,000 pounds with some tires on the front you lose total control. My name is [XXX] . My email is [XXX] my phone number is [XXX] thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    THIS IS NOT A SINGLE ISOLATED INCIDENT. THERE HAVE BEEN A LARGE NUMBER OF OWNERS WITH THIS ISSUE AND THE MANUFACTURER HAS NOT PROVIDED AN ACCEPTABLE SOLUTION. *DT ON THE 2015-2018 TIFFIN ALLEGRO BUS ON THE POWER GLIDE CHASSIS, A CRITICAL DESIGN DEFECT EXISTS WITH THE ENGINE FAN DRIVE TENSIONER BRACKET AND TENSIONER PULLEY ASSEMBLY. THE FAN DRIVE IS DESIGNED TO ENGAGE AT A PRE-DETERMINED ENGINE COOLANT TEMPERATURE AND IS UTILIZED TO LOWER ENGINE TEMPERATURE AS THE ENGINE COOLANT TEMPERATURE REACHES A HIGH LEVEL. THE TENSIONER BRACKET IS CONSTRUCTED FROM HEAVY GAUGE STEEL PLATE THAT IS WELDED TOGETHER AND THE TENSIONER PULLEY ASSEMBLY IS A CAST/MACHINED ALUMINUM ASSEMBLY. THE ASSEMBLY WEIGHS OVER 20 POUNDS. AS DESIGNED, THE FAN DRIVE TENSIONER ASSEMBLY CANNOT SUFFICIENTLY HANDLE THE TORQUE AND VIBRATION GENERATED WHEN THE FAN DRIVE ENGAGES. THE TENSIONER BRACKET AND PULLEY DEVELOPS MICRO-CRACKS THAT QUICKLY DETERIORATE INTO MAJOR CRACKS IN THE STEEL BRACKET AND TENSIONER PULLEY CAUSING A SUDDEN TOTAL FAILURE OF THE BRACKET, WHICH IN A WORSE CASE SITUATION, RESULTS IN THE BRACKET BREAKING INTO SEVERAL PIECES AND BECOMING DISCHARGED FROM THE REAR OF THE MOTORHOME AT HIGHWAY SPEEDS. WHEN THE BRACKET FAILS, THE ENGINE FAN DRIVE IS INOPERABLE, AND THE MOTORHOME OPERATOR EXPERIENCES A RAPID INCREASE IN ENGINE TEMPERATURE AND THE ENGINE SHUTS DOWN, POSSIBLY CAUSING A LOSS OF VEHICLE CONTROL.. SHOULD THE FAN DRIVE TENSIONER AND TENSIONER BRACKET BECOME DISLODGED FROM THE MOTORHOME ENGINE COMPARTMENT, IT COULD STRIKE ANOTHER VEHICLE OR PERSON CAUSING SEVERE DAMAGE, INJURY, OR POSSIBLE DEATH. TO DATE THE MANUFACTURER HAS BEEN UNABLE TO DESIGN/PROVIDE A FAN DRIVE TENSIONER ASSEMBLY THAT WILL WITHSTAND THE TORQUE AND VIBRATION BEING GENERATED. THE MANUFACTURER SHOULD IMPLEMENT A RECALL OF THE FAN DRIVE TENSIONER BRACKET AND TENSIONER PULLEY ASSEMBLY,

    This was a letter to our dealers we sent out when we first heard of the Kidde fire extinguisher recall, even though it was still unofficial. We knew our coaches on the dealers' lots contained Kidde and could not be sold unreplaced.
