FCA US is recalling 75,364 2015 model-year Jeep Cherokees in the U.S. because air conditioning lines may have been installed too close to the engine exhaust manifold, posing a fire risk, the automaker said.

FCA US launched an investigation into the problem after the National Highway Traffic Safety Administration received two customer complaints involving smoke and fire, the company said.

“Affected customers will be advised when they may schedule service, which FCA US will provide free of charge,” the company said in a released statement about the recall. "Customers who observe air-conditioning loss or any other concern, such as a dashboard warning light, should contact their dealers.”

Additional vehicles are affected in other markets, too. They include an estimated 7,571 in Canada, 4,018 in Mexico, and 6,942 outside the NAFTA region, FCA US said.

Vehicle owners can reach the FCA US customer information center at (800) 853-1403.
