Two Chrysler vehicle models have been recalled.

According to a press release, Chrysler Group LLC and the National Highway Traffic Safety Administration have resolved their differences with respect to the NHTSA’s request to recall two Chrysler models.

The two models recalled are 1993-2004 Jeep Grand Cherokees and 2002-2007 Jeep Liberty vehicles.

Chrysler Group says that the recall will include a visual inspection of the vehicle, and if necessary, provide an upgrade to the rear structure of the vehicle to better manage crash forces in low-speed impacts.

The group will reportedly install trailer hitches on the affected vehicles that do not already have the hitches installed.

Chrysler says their data analysis holds that the vehicles are not defective, but they are willing to take further steps to provide additional measures to supplement the safety features of the vehicles.

The NHTSA requested the recall, saying that the fuel tank placement in the vehicles leaves them less protected in the event of a rear-end crash, which could lead to leaks and fires.
