Chrysler Group announced two global recalls covering more than 184,000 SUVs, including Jeep Grand Cherokees and Dodge Durangos, and nearly 382,000 trucks, including Ram 2500 and 3500 pickups.

The truck recall affects 2010-2014 model-year Ram 2500 and 3500 pickups, along with 4500 and 5500 chassis cabs. All are equipped with 6.7-liter Cummins diesel engines. An estimated 381,876 trucks are involved.

This recall was prompted by an investigation into two cases where fuel-heater housings showed signs of overheating. Chrysler engineers discovered that a terminal connector near the fuel heater may be susceptible to friction-induced corrosion – a condition that can lead to overheating and fuel leakage.

However, Chrysler said, there are no known incidents involving fire. Additionally, the company is unaware of any related injuries or accidents.

To fix the problem, service technicians will install new terminals made from upgraded material. The technicians will also inspect the fuel-heater housings for any signs of leakage. When necessary, the housings will be replaced at no cost to customers.

The truck recall affects an estimated 314,704 trucks in the U.S., 59,432 in Canada, 1,803 in Mexico, and 5,937 outside of the NAFTA region, Chrysler said.

The SUV recall, affecting an estimated 184,186 vehicles, will address a problem with the electronic stability control, the automaker said. This recall campaign covers 2014 model-year Dodge Durango and Jeep Grand Cherokee vehicles.

Chrysler engineers discovered that a debris cover protecting a circuit board might inadvertently disrupt a communication line and disable electronic stability control. The company said it isn’t aware of any injuries or accidents related to the problem. A software upgrade will restore proper communication and preserve ESC function.

This recall will begin next month. The repairs will be free of charge to customers.

An estimated 132,223 of the SUVs are in the U.S., 8,871 are in Canada, 4,742 are in Mexico, and 38,350 are outside of the NAFTA region, Chrysler said.

Chrysler Group will notify vehicle owners of the recall plans and advise them when to schedule service. Owners can reach Chrysler's customer information center at 1-800-853-1403.
