2011 Chevrolet Impala Fuel System Problems

MULTIPLE THROTTLE BODY FAILURES, FIRST ONE WAS REPLACED BY GM AT 33K MILES LAST UNTIL ABOUT 70K SINCE 2017 HAD TO REPLACE 3 MORE TIMES ALL NEW PARTS BEING UNDER WARRANTY. ON 4TH THROTTLE BODY NOW, USUALLY HAPPENS WHEN CAR IS IN NORMAL CITY DRIVING...

FUEL TANK SHIFTS WHEN TAKING OFF .I BELIEVE THIS COULD CAUSE THE TANK TO LEAK AND COULD CAUSE A FIRE. I BELIEVE THIS VEHICLE SHOULD BE PUT ON THE RECALL LIST..IWAS TOLD BY GM THAT THERE WAS NOTHING THE COULD DO ABOUT IT. *TR

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? ALSO I EVEN CLEANED THE THROTTLE MOTOR AND POSITION SENSOR UNDER THE HOOD, IT SEEMED TO HELP FOR A LITTLE WHILE. *TR

FUEL SHIFT AROUND IN BRACKET.I AM AFRAID A HOLE WILL DEVELOP AND COULD LEAK FUEL AND CAUSE A FIRE I BELIEVE THE FACTORY SHOULD BE RESPONSIBLE FOR THE REPAIR.I WAS TOLD BY GENERAL MOTORS THAT IT WAS NOTHING THEY COULD OR WOULD DO. *TR

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
