Ford had a rough time with the Explorer after reports of exhaust fumes entering the cab of the vehicle, especially with police versions of the vehicle.

But, consumers and Ford were concerned enough to offer to inspect 2011-2015 for carbon monoxide leaks from the exhaust system.

From our BFF's at The Consumerist:

"The inquiry came about after the agency (National Highway Transportation Safety Administration) received 154 consumer complaints — including one crash — related to the smell of exhaust fumes in the passenger compartment."

And Ford will take certain steps to ensure the vehicles are safe.

From Ford:

" To reduce the potential for exhaust to enter the vehicle, dealers will reprogram the air conditioner, replace the liftgate drain valves and inspect sealing of the rear of the vehicle at no cost to the customer."
