After a prolonged dispute with the National Highway Traffic Safety Administration (NHTSA), Chrysler has recalled 2.7 million Jeeps at the government’s request.

The models affected: 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty vehicles.

According to the NHTSA, the vehicles are frequently involved in deadly fires after rear crashes.Regulators say the position of the gas tank, behind the rear axle, makes the Jeeps more susceptible to a fiery crash than similar models.

Chrysler insists the claims are untrue. However, the automaker noted that “this matter has raised concerns for its customers” and has agreed to the recall.

Chrysler will have dealers conduct “visual inspection of the vehicle” and “will, if necessary, provide an upgrade to the rear structure of the vehicle to better manage crash forces in low-speed impacts.”
