_ About 400 Twister Hammerhead dune buggies, manufactured in China and imported by TJ Power Sports LLC, because the seat belt's shoulder buckle adjustment can break under stress or if the buggy hits another object. This puts the driver and passenger at risk of being thrown from the buggy or other injuries. The company has received one report of a seat belt break that resulted in nerve damage to a rider's arm. The buggies were sold online and by Twister dealers around the country between July and December 2004. Details: by phone at 800-638-2772; by Web at http://www.tjpowersports.com or http://www.cpsc.gov.
