Carbon monoxide leakage into cab of 1998 Ford Ranger caused severe sleepiness while driving to and from work and while at home. Each day for about a month I was experiencing dizziness, sleepiness and nausea. I had a small accident when I feel asleep while stopping for a red traffic light and ran into the back of another vehicle. I reported my dizziness and sleepiness to my supervisor who notified our medical department and they sent me home. I had a medical stress test performed; it was ok', a sleep study performed and the cardiologist increased my dosage of a beta blocker. I was finally released to return to work two months later. I had taken my vehicle to my local Ford dealer shortly after I was sent home and they reported there was no co leaking into my cab. I tried discussing my problem with the Ford Motor Company's customer service department a couple of times, but they said the service technician could find nothing wrong and that's all they could do for the carbon monoxide was entering into my cab from the exhaust of other vehicles on the road. I finally found and bought a digital carbon monoxide detector which would read any level of co detected. The first day I drove to work it indicated 18 ppm co poison and another 16 ppm co poison on the drive home after work which totaled around 34 ppm per day for over a month. I immediately went to my doctor and requested a blood gas test which indicated a high level of co in my blood. It was confirmed by the pulmonary doctor that the sleepiness was caused by co poisoning entering the cab of my truck. My truck is now parked in my drive way and has not been driven for over three months.
