NHTSA Complaint #10421257 — 2004 CHEVROLET SUBURBAN

I OWN A 2004 CHEVROLET SUBURBAN 1500 WHICH I BOUGHT USED IN 2006. SINCE THE DAY I PURCHASED THE VEHICLE THE BACK DOORS WILL NOT AUTOMATICALLY UNLOCK EITHER WITH DECREASED SPEED OR WITH THE HAND HELD REMOTE. YOU ACTUALLY HAVE TO REACH BACK AND UNLOCK THE DOORS WITH YOUR HAND. NOW, IN THE LAST FEW MONTHS, THE REMOTE STILL WORKS BUT IT IS NOT UNLOCKING ANY OF THE DOORS AND YOU MUST USE THE KEY TO UNLOCK DRIVERS DOOR. I WAS TOLD THERE ARE MOTORS IN EACH DOOR FOR THE LOCKS AND THAT REPLACING THEM ARE EXPENSIVE, SO I'M WONDERING IF THERE HAVE BEEN ANY KIND OF RECALLS FOR THIS PROBLEM. *TR
