I BOUGHT A USED 2004 IMPALA IN AUG. 2008 AND BASICALLY SINCE THE FIRST DAY I GOT IT I HAVE HAD PROBLEMS WITH THE SPEEDOMETER. THE DEALER PROMISED TO HAVE IT REPAIRED, BUT HAS YET TO DO SO. THEY KEEP GIVING ME THE RUN AROUND, AND NOW FOR THE PAST MONTH MY STEREO HAS STOPPED WORKING. YESTERDAY MY FUEL GAUGE STARTED GOING HAYWIRE. THE INTERIOR LIGHTS ONLY WORK SOMETIMES. THE LOW TIRE PRESSURE WARNING LIGHT WONT RESET. THIS IS A SAFETY PROBLEM THAT NEEDS TO BE RECALLED. BECAUSE OF MY SPEEDOMETER NOT WORKING I ALMOST WENT OFF THE SIDE OF A FREEWAY ON RAMP FROM NOT BEING ABLE TO TELL HOW FAST I WAS GOING. I JUST HAD TO PRAY THAT I HAD SLOWED DOWN ENOUGH TO MAKE THE CURVE. IS SOMEONE GOING TO HAVE TO BE SERIOUSLY INJURED OR DIE BEFORE THERE IS A RECALL ON THIS. I HAVE BEEN TO SEVERAL WEBSITES RESEARCHING THE 2004 IMPALA AND THERE ARE HUNDREDS OF COMPLAINTS ALL SAYING THE SAME THING. ITS TIME THAT GM TAKES RESPONSIBILITY AND DOES SOMETHING ABOUT IT. I AM NOT ABLE TO HAVE MY CAR REPAIRED BECAUSE OF THE COST. IT'S WAY TO EXPENSIVE. I WILL NEVER BUY ANOTHER GM VEHICLE. *TR

THE TIRES KEEP LOOSING AIR IT TAKES ABOUT 2 DAYS FOR THEM TO LOOSE ABOUT 10LBS. THEY ARE LEAKING BECAUSE OF CORROSION OF THE WHEEL WHERE THE TIRE BEAD HAS TO SEAL. THE CAR HAS THE INDY SPECIAL EDITION CHROME PLATED ALUMINUM WHEELS. THE PROBLEM IS CAUSED BY THE CHROME PEELING OFF OF THE ALUMINUM IN THE BEAD AREA THE CORROSION CAUSES DEEP PITS THAT WILL NOT LET THE TIRE SEAL. THE DEALERSHIP RECOMMENDED TO PUT INNER TUBES IN THE TIRES WHICH ARE UNSAFE BECAUSE OF SUDDEN DEFLATION IN CASE OF A PUNCTURE. THE WHEELS WOULD COST I THINK OVER $2000 TO REPLACE THE SET. I THINK THIS IS VERY BAD QUALITY ON CHEVY PART. 4 WHEELS BAD ON A CAR IS NOT A NORMAL MAINTENANCE ISSUE. IT IS A SAFETY ISSUE BECAUSE OF THE CONSTANT AIR LOSS. 2004 CHEVY IMPALA SS INDY EDITION. *TR
