Carbon monoxide problems plague Ford Explorers

Excess carbon monoxide (CO) emissions could be behind several crashes and injuries involving Ford Explorer models, including Police Interceptor Utility variants. The National Highway Traffic Safety Administration (NHTSA) in the US opened a Preliminary Evaluation into certain Explorer models in July 2016 after receiving 154 reports of exhaust odours in the vehicle occupant compartment. It is now stepping this up into an 'engineering analysis', one step before it would issue a recall instruction to the OEM. The analysis covers an estimated 1,333,000 model year (MY) 2011 to 2015 Explorers.
