Toyota Motor Sales U.S.A. Inc. is recalling 128,000 2002-04 Toyota Camrys because side airbag curtains may not work properly, the National Highway Traffic Safety Administration announced last week. The agency said the curtains may be twisted near their inflators and may not deploy fully in a crash. Volvo Cars of North America Inc. said last week it is recalling about 105,000 1994-97 850 sedans because their gasoline tanks may leak. The company said that new heat shield mounting bushings will be installed on all affected cars. Fuel tanks will be replaced if they have begun to leak. Volvo said the problem develops only after the cars have prolonged exposure to extreme heat, according to a report in Automotive News.
