2001 Chevrolet Suburban 1500

WHEN VEHICLE IS IDLING WHILE NOT MOVING EXTREME AMOUNTS OF EXHAUST FUMES ARE ENTERING THE CABIN AREA THROUGH THE VENTILATION SYSTEM. THIS IS DUE TO DEFECTIVE EXHAUST MANIFOLD BOLTS WHICH ARE BREAKING ALLOWING THE EXHAUST MANIFOLD TO OPEN AND ALLOW FUMES TO ENTER THE ENGINE COMPARTMENT WHICH RESULTS IN THE EXHAUST FUMES ENTERING THE PASSENGER CABIN AREA THROUGH THE VENTILATION SYSTEM. THIS IS A HEALTH ISSUE FOR PASSENGERS INSIDE THE CABIN BREATHING THE TOXIC EXHAUST FUMES. THIS SHOULD BE A SAFETY RECALL ON GM TO FIX THE PROBLEM DUE TO POOR ENGINEERING DESIGN AND FOR USING POOR QUALITY COMPONENTS WHICH FAIL FOR NO REASON. ALSO THIS IS AN EXTREMELY DANGEROUS SITUATION FOR PASSENGERS INSIDE THE VEHICLE, WHICH HAVE TO BREATH THE DANGEROUS EXHAUST FUMES. GM SHOULD BE MADE TO REPAIR ALL VEHICLES AFFECTED BY THIS PROBLEM WHICH WERE DESIGNED AND ENGINEERED WITH INFERIOR PARTS WHICH ARE CAUSING THIS DANGEROUS SITUATION FOR MILLIONS OF PEOPLE ACROSS THIS COUNTRY.
