my husband is sick, from carbon monoxide poisoning

I told my husband that I cant stand the exhaust smell in his truck,, the Journey,, and he would just try to close of the ventilation to reduce the odor,, but he then began falling asleep, with head aches, and nausea. He is very ill, from carbon monoxide poisoning due to the exhaust from the engine in blowing back into the cabin of the truck,, I am so pissed, American made sucks...
