VEHICLE DISPLAYS "REDUCED POWER" "SERVICE STABILITRAK SYSTEM". I REPLACED THE THROTTLE POSITION SWITCH (TPS) AND IT HAS CAME BACK AGAIN. SERVICE LIGHT IS ON AND READS P2138, TPS. ON HUNDREDS OF FORUMS PEOPLE ARE COMPLAINING OF THIS SAME PROBLEM, SHOULDN'T THIS BE RECALLED?

WHEN I LEFT MY HOUSE TO RUN TO THE STORE THE GAS GAUGE WAS READING HALF A TANK. THE STORE I RAN TO WAS 6 MILES UP THE ROAD, WHEN I STARTED THE CAR AND WAS COMING HOME I NOTICED THE GAS GAUGE WAS BELOW A QUARTER OF A TANK. BY THE TIME I GOT BACK HOME (6 MILES AWAY) THE GAUGE WAS READING BETWEEN HALF AND A QUARTER TANK. I ALSO HAD A 2007 SILVERADO THAT DID THE SAME THING, NOT SURE BUT MAYBE CHEVROLET NEEDS TO SEED A RECALL OUT FOR THE FUEL GAUGE SENDING UNITS. I HAVE TALKED TO OTHER CHEVY OWNERS THAT HAVE HAD THE SAME ISSUE. *TR
