I RECEIVED A LETTER FROM CHEVROLET STATING IN SOME VEHICLES, THE FUEL LEVEL SENSOR MAY WEAR PREMATURELY CAUSING THE FUEL GAUGE TO READ EMPTY AFTER FILLING THE TANK. IT ALSO STATES THE GAUGE WILL EVENTUALLY STOP WORKING. THIS IS EXACTLY WHAT HAS HAPPENED TO MY TRUCK. IT ALSO STATES THAT GM WILL PAY 50% OF THE TOTAL COST FOR AN AUTHORIZED CHEVROLET DEALER TO REPAIR MY VEHICLE. I BELIEVE THIS SHOULD BE A RECALL AND I SHOULD NOT HAVE TO PAY ANYTHING FOR IT SINCE I AM NOT THE ONLY ONE WITH A 2005 TRAIL BLAZER WITH THE SAME PROBLEM. *TR
