The Ford Explorer recently made headlines due to exhaust fumes entering the cabin and making people nauseous. The National Highway Traffic Safety Administration received more than 2,400 reports on the issue, with at least 41 citing injuries and three reporting crashes due to the ill effects of the carbon monoxide fumes on the 2011 through 2017 Explorer. However, investigations by the NHTSA and Ford turned up no significant changes in CO levels in the cabin. Well, except for Police Interceptor models. Ford says the issue stems from aftermarket up-fit companies leaving unsealed holes from the installation of police equipment. Still, Ford says it will fix any of the 1.3 million affected Explorers at the owner’s request, despite Ford calling the vehicles safe.
