More than 500,000 Jeep and Dodge SUVs are being recalled because of two unrelated flaws, USA Today reports.

The global effort affects the 2014 Dodge Durango and 2014 Jeep Grand Cherokee, whose stability controls might not function properly.

The recall also includes the 2010-14 model years of the Ram 2500, 3500, 4500 and 5500, in that case because diesel-fuel heaters might overheat.

The fault discovered with the Jeep and Dodge brands is threefold, concerning features known as the Occupant Restraint Control, or OCR; the Steering Column Control Module, or SCCM; and the Electronic Stability Control, or ESC, Consumer Affairs explained.

"Due to a fault within the ... (OCR) module, the frontal air bags, seat belt pretensioners, and side air bags may be disabled. The malfunction indicator light 'MIL' should illuminate to initially warn drivers of a failure," the advocacy organization detailed.

A steering column control feature, meanwhile, could end in the stability control being disabled. In a worst-case scenario, this could lead to the driver losing control of the vehicle.

For the Ram models, the problem lies with fuel heater for their 6.7-liter Cummins diesel engine, according to USA Today. An investigation revealed that, in at least two cases, the device's housing showed signs of overheating.

Neither malfunction has contributed to any accident or injury, parent company Chrysler said in a statement. The automaker has formed part of Fiat Chrysler Automobiles since 2004, when the Italian automaker completed its acquisition of its American counterpart.

Chrysler will contact the owners of the affected vehicles to schedule the necessary repairs, which will be free of charge, the company announced.

Almost 90 percent of the cars were sold in the United States, while a little more than 1 percent went to Mexico. The remaining vehicles are located in Canada and outside North America.

Chrysler said it has made channels available for customers who wish to contact the automaker concerning the malfunctions, the Car Connection advised. Owners are asked to call 1 (800) 853-1403 and make reference to "Recall P64." They also have the option of contacting the National Highway Traffic Safety Administration at (888) 327-4236, referencing "Safety Campaign 14V636000."
