NHTSA Complaint #10010746 — 2002 CHEVROLET IMPALA

02' CHEVROLET IMPALA. USING THREE DIFFERENT CONFINED SPACE MONITORS I HAVE FOUND CONTINUING PRESENCE OF CARBON MONOXIDE AND METHANE EMISSIONS IN THE INTERIOR/CAB OF MY VEHICLE. GM HAS INSPECTED THE VEHICLE AND HAS ALSO FOUND THE PRESENCE OF VEHICLE EMISSIONS INSIDE THE VEHICLE BUT, THEY CONTEND THE AMOUNTS ARE WITHIN EPA STANDARDS. THE PROBLEM IS ON GOING AND CONTINUES TO BE A HEALTH RISK FOR MY FAMILY. FREQUENT HEADACHES AND FATIGUE ARE OFTEN AFFECTS AFTER OPERATING THE VEHICLE. NAUSEA HAS OCCURRED AFTER LENGTHY TRIPS IN THE VEHICLE. WE HAVE RESULTED TO DRIVING WITH THE WINDOWS DOWN TO HELP ALEVE THE EFFECTS ON THE CARBON MONOXIDE, BUT THIS ISN'T THE SOLUTION. THE EMISSIONS ALSO CREATES AN ODOR THAT CLINGS TO YOUR BODY. WHAT CAN I DO? *NLM
