An investigation into fuel tank problems could have the National Highway Traffic Safety Administration (NHTSA) recalling Ford F-150 pickup trucks. The investigation was started a year ago after 32 complaints of fuel tanks falling off. Today over 240 complaints have been received, with 95% of the reported incidents resulting in fuel spillage. If the investigation leads to a recall, almost three million 1997-2001 F-150 trucks could be recalled. Ford is cooperating with the NHTSA and encourages owners to contact their local dealer if they have any questions about the investigation.
