Carbon monoxide in the passenger compartment of a 2018 Ford interceptor utility (a honeywell bwc2r-m carbon monoxide alarm had been installed in the vehicle due to the history of carbon monoxide issues with these vehicles). On October 21, 2019 two officers were patrolling in the 2018 Ford interceptor utility. The officer were accelerating quickly as they entered the highway when the carbon monoxide alarm activated. The officer stopped accelerating and rolled down the windows. The carbon monoxide alarm reset and no further activations have been reported. (this report came a month after another of the city's Ford interceptor utility vehicles went to the dealership twice for carbon monoxide in the passenger cabin. The first incident was accompanied by a foul odor and the egr purge valve was replaced. The vehicle was placed back in service and within a week the carbon monoxide alarm activated again. Ford was unable to duplicate the carbon monoxide in the passenger cabin so no repairs were done. ).
