NHTSA Complaint #10220387 — 2003 CHEVROLET IMPALA

I DISCOVERED ACCIDENTALLY THAT MY 2003 CHEVROLET IMPALA HAS A DESIGN DEFECT THAT MAY CAUSE SOME HEALTH PROBLEMS AND POSSIBLE LEAD TO DEATH. IN THE RIGHT REAR QUARTER PANEL OF THE CAR IS A DEVICE THAT IS CALLED A BODY PRESSURE VALVE THAT VENTS CABIN PRESSURE. THE PROBLEM IS IT LETS SNOW AND RAIN IN THE STAGNANT WATER SITS IN YOUR FENDER AND IS A BREEDING GROWN FOR GERMS. THE DEALER WAS SHOCKED WHEN I BROUGHT IT IN AND ASKED ME WHAT MADE ME THINK TO REMOVE THE CARPET AND LOOK IN THE FENDER. ALL THEY COULD DO WAS TAKE THE WATER OUT. STANDING WATER IN A FENDER WILL CAUSE A RUST PROBLEM. I ASKED THEM WHAT COULD BE DONE AND THEY TOLD ME TO PUT A NEW VALVE IN. THAT WILL NOT CORRECT THE PROBLEM BECAUSE THE FLAP IS NOT AIR TIGHT AND IS VENTED WATER AND FUMES SUCH AS CARBON MONOXIDE CAN ENTER THE CAR THROUGH IT . THE EXHAUST IS ONLY 12 INCHES OR LESS FROM IT. THE OWNERS MANUAL STATES DO NOT RUN THE CAR WHEN SITTING STILL LETS ME KNOW THAT GM KNOWS ABOUT THIS PROBLEM . WE ALL HAVE BEEN TOLD NOT TO RUN CARS IN ENCLOSED BUILDINGS BUT THIS IS TOO MUCH. IF IDLING IN TRAFFIC ONE MUST BE ASTUTE ENOUGH TO KEEP THEIR VEHICLE FAN ON AND OUTSIDE AIR COMING INTO THE VEHICLE AT ALL TIMES SO NOT TO ALLOW THE CAR TO FILL UP WITH FUMES FROM THE TAIL PIPE THAT SITS BENEATH THE PRESSURE VALVE. WHAT A DUMB DESIGN. CAR WAS SERVICED ON 03/04/08 I WAS ALWAYS SPRAYING DEODORIZER IN THE TRUNK AND IT SMELLED LIKE A CESSPOOL AS FAR AS THE REST OF THIS REPORT GOES THE NUMBER OF FAILURES IS TOTAL FAILURE IT HAS NEVER WORKED AND COULD BE CONSTRUED TO BE CRIMINAL NEGLECT. *TR
