2012 Chevrolet Impala Fuel System Problems

Fuel pump replacement with Gm dealership parts provider now car engine doesn't shut off right after key is turned off and car doesn't want to talk gas when fueling then doesn't want to start after fueling

CHECK ENGINE, FUEL TANK WILL NOT FILL, CAR RUNS OK

WHILE DRIVING ON THE HIGHWAY THE CHECK ENGINE LIGHT & TRACTION LIGHT CAME ON AT THE SAME TIME AS THESE 3 MESSAGES, ENGINE MAY LOOSE POWER, SEVERICE TRACTION CONTROL, STABILITRACK. THE ENGINE STARTED SLOWING DOWN & HAD A HIGH PITCHED WHINNY NOISE. AFTER ABOUT 10 MILES THE MESSAGE CHANGED TO ENGINE IIS LOOSING POWER, WOULDN'T GO OVER 35 MPH AND THE WHINNING BECAME LOUDER AND FASTER. I HAD TO HAVE IT TOWED TO A GM DEALERSHIP, WHERE THEY DIAGNOSED IT AS THE HIGH PRESSURE FUEL PUMP. I WAS TOLD THE PARTS ARE ON BACK ORDER UNTIL MAY 15, 2018.

I WAS DRIVING TO WORK. MY CAR STARTED TO LOSE SPEED. UNTIL IT CAME TO A COMPLETE STOP. I CALLED FOR A TOW TRUCK, THAT TOWED MY VEHICLE TO A REPAIR SHOP. AFTER DIAGNOSIS OF MY CAR THE REPAIR GUY, INFORMED ME IT WAS MY MODULE FUEL PUMP FLOW CONTROL. I WANTED TO KNOW MORE SO I GOOGLE THE PROBLEM. I CAME ACROSS A RECALL ON GM SITE, BULLETIN 14515B. I NOTICED IT WAS A RECALL FOR EXACTLY THE SAME ISSUE I WAS HAVING. SO I CALLED CHEVROLET TO SEE WHAT STEPS I NEEDED TO TAKE ON GETTING REIMBURSED FOR AN ISSUE THAT CLEARLY HAS BEEN A PROBLEM ON SEVERAL 2012 IMPALA'S. I WAS TOLD,IT WAS A RECALL BUT NOT ON MY 2012 BECAUSE MY VIN # BEGIN WITH A W. I EXPLAIN TO HER THAT DIDN'T MAKE SENSE TO ME. ALL 2012 WAS IN PRODUCTION AT THE SAME TIME. I'M PRETTY SURE THEY USED THE SAME PART ON THE VEHICLE. I WAS TOLD IT WAS NOTHING SHE COULD DO. I INFORMED HER I WILL BE FILING A COMPLAINT.

THE ENGINE GOES DEAD WITHOUT WARNING WHILE I'M DRIVING DOWN THE ROAD. NO LIGHTS ON OR ANY OTHER INDICATIONS THAT IT IS ABOUT TO HAPPEN. WILL NOT RE CRANK. REALIZE THAT IT HAPPENS WHEN MY FUEL SYSTEM IS ABOUT 60 MILES TO EMPTY. AFTER PUTTING GAS IN I CAN CRANK IT RIGHT UP AND GO UNTIL IT HITS AROUND 60 MILES TO EMPTY AND IT WILL GO DEAD AGAIN WITHOUT WARNING, VERY DANGEROUS AND SCARY THING TO HAPPEN IN TRAFFIC. DEALERSHIP TECHNICIAN IS STUMPED AS TO WHAT IT IS, THEY HAVE CHANGED ONE PART AND IT DID NOT WORK, ENGINE WENT DEAD ON HIM ALSO WHEN HE TESTED DROVE IT, CAR HAS BEEN THERE FOR ALMOST 2 WEEKS NOW AND THEY DON'T KNOW WHAT TO DO. I NEED MY CAR BACK.

THE VEHICLE HAS A LOUD KNOCKING SOUND FROM THE HIGH PRESSURE FUEL PUMP WHEN YOU TAKE OFF FROM A STOP. *TR

2012 CHEVROLET IMPALA LT. CONSUMER STATES HIGH PRESSURE FUEL PUMP IS VERY NOISY WHEN ACCELERATING FROM A STAND STILL AND ALSO STATES ISSUES WITH VIBRATION *TGW THE CONSUMER STATED THE ACCELERATOR MOTOR MADE A LOUD NOISE. THE CONSUMER STATED THE FUEL LINES, WHICH APPARENTLY RUN DIRECTLY UNDER THE DRIVER'S SIDE FLOOR, VIBRATE DUE TO THE HARMONICS SET UP BY THE HIGH PRESSURE FUEL PUMP. THE VIBRATION IS CONTINUOUS AND CAN BE FELT THROUGH THE FLOOR AND UP INTO THE DRIVER'S SEAT. *JB
