Chrysler Group announced plans to conduct three recalls affecting approximately 1.2 million trucks, though as many as 726,000 may not need repair.

Approximately 968,000 of the 1.2 million vehicles are in the U.S. About 157,000 are in Canada, 37,100 in Mexico, and 18,000 outside the NAFTA region. The recall campaigns will target an estimated 453,000 vehicles with steering-system tie rods that may have been misaligned during assembly or steering-system service, the automaker said.

Chrysler Group said it is “casting the net wider than necessary to identify those vehicles that require repair. Any found to have suspect tie-rod assemblies will have those components replaced at no cost to customers.”

One recall will inspect an estimated 842,400 2003-2008 model-year Ram 2500 and 3500 trucks to find approximately 116,000 repaired with tie-rod assemblies that could become misaligned. This condition could lead to component fracture and steering loss.

Two additional recall campaigns will target those vehicles known to have tie-rod assemblies linked to previous recalls. They comprise 294,000 2008-2012 model-year Ram 2500 and 3500 pickups, chassis cabs and 2008 Ram 1500 4x4 Mega Cabs, as well as 43,500 2008-2012 model-year Ram 4500 and 5500 4x4 chassis cabs.

Chrysler Group said it is aware of six accidents and two injuries involving 2008-2012 model-year 2500 and 3500 trucks and one additional accident with no injuries involving the remaining models.

Vehicle owners will be notified by mail next month with instructions for making service appointments.

Work could begin as early as January. Customers who own affected 4500 and 5500 models may bring their vehicles to Chrysler Group dealers for interim service because replacement parts may not be available until late 2014, the company said. Interim service would involve component inspections and, if necessary, realignment.
