2014 Subaru Impreza

THE GAS GUAGE INNACCURATELY DESCRIBES HOW MUCH GAS IS LEFT IN THE TANK. I FILLED MY TANK FROM 40 MILES TWO WEEKS AGO. I PAID $32 FOR THE GAS AND IT ONLY READ 170 MILES TILL EMPTY UNLIKE THE USUAL 300 MILES. 5 HOURS LATER, WHEN IT CORRECTED ITSELF, RETURNING TO 300 MILES. THIS WEEK, UPON FILLING MY CAR UP AT 40 MILES TILL EMPTY, I PAID $28. MY CAR READ 280 MILES TILL EMPTY AND THEN SHOT UP TO 300 MILES HALF AN HOUR LATER. I FEEL UNSAFE TO LET MY CAR GO LONG PERIODS OF TIME WITHOUT FILLING WITH GAS. I CALLED MY LOCAL SUBARU DEALERSHIP AND THEY WANTED ME TO WAIT ALMOST 3 WEEKS TO BRING MY CAR IN, EVEN WHEN STATED THAT I HEARD OF THIS HAPPENING PREVIOUSLY WITH OTHER 2011-2016 SUBARU IMPREZAS. THEIR RESPONSE WAS LESS THAN COMFORTING "CLAIMING" THEY HAVE HAD NO PRIOR KNOWLEDGE OR TRENDS OF THIS HAPPENING WITH MY GENERATION IMPREZA, ONLY THE NEWER MODEL IMPREZAS AND CROSSTREKS.

ABOUT 6-8 MONTHS AGO AS I WAS MAKING A TURN I PRESSED THE BRAKE PEDAL AND INSTEAD OF SLOWING DOWN THE ENGINE THROTTLED UP. AND AFTER A FEW MOMENTS WENT BACK TO NORMAL. TWO WEEKS AGO AS I PRESSED THE BRAKE PEDAL WHILE COMING TO A STOP SIGN THE ENGINE THROTTLED UP AND I HAD DIFFICULTY COMING TO A STOP. I PUT THE CAR IN PARK AND TURNED IT OFF. WHEN I STARTED IT AGAIN THE ENGINE IMMEDIATELY WENT TO HIGH THROTTLE TO THE POINT THAT THE FRONT OF THE CAR STARTED VIBRATING. I TURNED IT OFF AGAIN AND RESTARTED IT AND THIS TIME IT WAS OK. I TOOK THE CAR INTO THE SUBARU DEALERSHIP. THEIR MECHANIC RAN THE DIAGNOSTICS AND WAS UNABLE TO PIN POINT THE PROBLEM. THEY DECIDED TO CALL THE SUBARU TECHNICAL DEPARTMENT AND WERE TOLD TO NOT LET ME DRIVE THE CAR UNTIL THEIR ENGINEER TOOK A LOOK AT THE PROBLEM. THIS WAS A WEEK AGO AND I HAVE NOT BEEN ABLE TO FIND OUT WHAT THEY HAVE FOUND.
