NHTSA Complaint #10663800 — 2007 TOYOTA TUNDRA

I RECENTLY PURCHASES A USED 2007 TOYOTA TUNDRA DOUBLE CAB FROM A PRIVATE PARTY. I TEST DROVE THE VEHICLE ON AC PAVEMENT WITH NO MAJOR ISSUES, BUT UPON PURCHASING AND DRIVING ON MY TYPICAL FREEWAY COMMUTE TRAVELING AT NORMAL SPEEDS (55-70MPH) IT SHAKES VIOLENTLY. THE SHAKING RESONATED AT ONE POINT SO VIOLENTLY THAT I LOST CONTROL OF THE VEHICLE AND HAD TO DRASTICALLY SLOW DOWN TO REGAIN CONTROL. I AM FEARFUL OF MY SAFETY AND THAT OF ANY PASSENGERS, ESPECIALLY MY CHILDREN. I HAVE SUBSEQUENTLY FOUND FORUM INFORMATION ONLINE THAT SPEAKS TO THIS "BED BOUNCE" PROBLEM, AND A RELEVANT TSB FROM TOYOTA. HOWEVER, I CANNOT FIND AN OFFICIAL TSB FROM TOYOTA ONLINE OR A GENUINE FIX TO THE PROBLEM. PLEASE HELP BECAUSE I FEEL LIKE I JUST BOUGHT A VEHICLE THAT IS NOT SAFE TO DRIVE, AND NEEDLESS TO SAY VERY ANGRY THAT TOYOTA HAS NOT ADDRESSED THIS PROBLEM IN FULL. *TR
