THE CAR HAD NOT YET HAD THE CUSTOMER SATISFACTION SERVICE FOR THE PLUGS AND SEALS COMPLETED. I HAD NOT NOTED ANY EXHAUST ODORS IN THE CAR AND HAD NOT PROBLEMS DURING MANY ALL DAY DRIVES. AFTER AN 11 HR DRIVE THIS WEEK WITH THE AC ON THE WHOLE TIME (NOT ON RECIRCULATING), I HAD MANY SYMPTOMS OF CO EXPOSURE (HEADACHE, DIZZY, NAUSEA) AND ALL 3 OF MY DOGS WER AFFECTED (POOR APPETITE, LETHARGIC). ONE OUT OF THE CAR I'M FRESH AIR FOR SEVERAL HOURS, THE SYMPTOMS SLOWLY DISSIPATED. WISH I HAD HAD A CO METER IN THE CAR. I HAD MILDER SYMPTOMS ON SEVERAL TRIPS (4-7HRS DRIVING IN ONE DAY) IN THE WEEKS BEFORE THIS LONGER TRIP. THESE WERE ALL HIGHWAY DRIVING AND CAR DID NOT IDLE WHILE SITTING.
