The National Highway Traffic Safety Administration (NHTSA) is in the process of investigating close to 280k 2001 to 2004 Pontiac Aztec and Buick Rendezvous SUVs after consumers filed 213 complaints with the organization.

Apparently, a faulty weld on the fuel tanks' filler pipe is causing a leak, allowing either gasoline fumes or fuel itself to escape from the pipe.

The announcement by NHTSA is part of the second stage of the investigation, however, no recall has been issued thus far.
