Tank Assembly problems of the 2011 Ford F-150

While braking to enter right hand turn in 2011 super crew fx2 f150 fuel sloshed causing engine to seize and power steering to shut off requiring hard break after loss of control of vehicle along with movement of the vehicle to level ground and restart of engine. Fuel level at time of incident was aprx 5. 3 gallons or aprx 1/5 of a 26 gallon tank. First incident at 600 miles, multiple incidents at 1600 miles, 2100 miles, 2500, 2800, and 3000 miles. Incident also occurs while nose down on anything above a 0% gradient. Also causes loss of control of vehicle. Ford advises that this is a known safety concern but there is no correction, advise was to always keep fuel levels above quarter tank at all times per advise of regional Ford service manager and town east Ford service department. Advised that fuel level indicator can't be relied on below this level (quarter tank) also advised by Ford that the safest level to maintain fuel level at was half tank. This failure does have the potential to and frequently does cause loss of control of vehicle. Ford also advises that this is an issue with all 2011 f150's and should be treated as normal. Additional information including photos, videos, and service records avail to NHTSA along with correspondence with Ford engineering department and service.
