NHTSA may reopen case on Jeep gas tanks as study links issue to 75 deaths. The Consumerist (4/10, Kieler, 54K) website reported that NHTSA may be “relaunching the investigation into millions of model year 1993 to 2007 Jeeps.” The announcement comes only five months after the agency closed the investigation on whether the rear-mounted fuel tanks in those models “sit too low and put the vehicle at risk of catching fire if involved in a rear-end explosion.” The article noted that Chrysler maintains that the design is not safety defect, but documents show “nearly 75 deaths” have resulted from the issue.
