NHTSA Complaint #10758684 — 2000 CHEVROLET CAVALIER

I HAD THE AIR CONDITIONER REPLACED. THE TECH SAID THE TENSIONER NEEDED TO BE REPLACED. ONE WEEK LATER I RETURNED AND HAD A NEW BELT TENSIONER INSTALLED. ABOUT A MONTH LATER THE NEW AIR CONDITIONER HAD PREMATURE FAILURE. I HAD IT REPAIRED UNDER WARRANTY AND ALSO HAD A NEW DRIVE BELT INSTALLED DURING THE REPAIR. ABOUT ONE YEAR LATER I BEGAN HEARING A CHATTER WHEN ACCELERATING FROM STOP POSITION AND HAD EXCESSIVE VIBRATION. I TOOK TO THE SHOP AND THEY SAID THE BELT TENSIONER WAS BAD. THIS SEEMS EXCESSIVELY SHORT LIFE SPAN FOR A REPLACEMENT PART OF GOOD QUALITY. TODAY THE SHOP TRIED THREE DIFFERENT TENSIONERS AND STILL IT WAS NOT CORRECTING THE ISSUE. I EVEN DOUBLE CHECKED THE BELT ROUTING PATTERN TO ENSURE IT WAS CORRECT. I DONT UNDERSTAND WHAT THE PROBLEM IS WITH THE BELT TENSIONERS FOR THIS VEHICLE. ALL MY PRIOR FORD VEHICLE NEVER HAD THIS PROBLEM WITH THEIR TENSIONERS OF SAME DESIGN. PLEASE LOOK INTO THIS PROBLEM AS A BELT THAT BREAKS OR SLIDES OF A PULLEY DUE TO A FAULTY TENSIONER CAN CAUSE IMMEDIATE LOSS OF POWER STEERING RESULTING IN HAZARDOUS AND POTENTIALLY FATAL DRIVING CONDITIONS AND SITUATIONS. ALSO THE BACKLIGHTING ON THE ODOMETER DOES NOT WORK.THE ODOMETER REGISTERS MILAGE DRIVEN BUT THE BACKLIGHT DOES NOT WORK AT ALL.PLEASE LOOK INTO AND DONT WAIT FOR SOMEONE TO HAVE TO DIE BEFORE THIS ISSUE BECOME IMPORTANT.THANKS.
