The Ford F-150 is now a part of an investigation by the National Highway Traffic Safety Administration (NHTSA) for fuel tank straps that may break due to corrosion, which could lead to a fire. In total 1.4 million F-150 models are affected, dating from 1996-2001.
NHTSA has received 32 complains regarding this issue from owners and in 28 of those cases one or both of the straps broke, causing the fuel tank to drop.
The number of complaints is minimal but NHTSA is being extra cautious lately and official investigation announcements are usually followed by a spike in official complaints.
