2005 CADILLAC STS Fuelpropulsion System Problems

IT JUST STARTED MAKING A LOUD KNOCKING NOISE, AND IT DOSENT GO NO FASTER THAN 40MPH.

MY FUEL HAND IS ALWAYS INACCURATE. WHEN IT GET CLOSE TO THE 1/8TH MARKER THE ENGINE COMPLETELY TURNS OFF DUE TO LACK OF FUEL. FROM MY UNDERSTANDING MY VEHICLE HAS ALREADY BEEN TAKEN IN FOR ALL RECALLS BUT THIS PROBLEM HAS NOT BEEN FIXED.

TL* THE CONTACT OWNS A 2005 CADILLAC STS. THE CONTACT STATED THAT THE VEHICLE FAILED TO START. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE TECHNICIAN DIAGNOSED THAT THE FUEL MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE CONTACT STATED THAT THE FAILURE RECURRED AFTER THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 147,000.

THIS VEHICLE HAS PUMPED THROUGH 5-7 QUARTS OF OIL APPX EVERY 500 MILES. I KNOW THAT THIS IS NOT NORMAL. CAR WAS OVERHAULED, THE TRANS WAS BASICALLY REBUILT, WITH NEW COMPONENTS.PROBLEM WITH OIL EVAPORATING AT VERY LOW MILEAGE STILL AN ISSUE. ***NO LEAKS*** OR SYMPTOMS ASIDE OF DIMINISHING OIL EVERY SAID SET OF MILES. VERY FRUSTRATING ISSUE THAT HASN'T BEEN RESOLVED. *TR

THE CATALYTIC CONVERTER MAKES LOUD POPPING NOISES ON PASSENGER FRONT SIDE. NOW IS MISFIRING IN CYLINDER 1 AND ALSO HAS UNEXPECTED GAINED SPEED WITHOUT ANY GAS PEDDLE PUSHED. GM EXTENDED THE CATALYTIC CONVERTER WARRANTY TO 200,000 MILES DUE TO CONVERTER PROBLEMS. BUT MY VIN THEY SAY ISN'T INCLUDED. MY CAR IS A V6. MY SISTER WAS THE PREVIOUS OWNER SHE SAID SHE NEVER RECEIVED ANY RECALL INFORMATION. THE WEBSITE SHOWS NO OPEN RECALLS BUT THE WORK WASN'T COMPLETED SINCE SHE PURCHASED IN 2007. GM WEBSITE DOESN'T HELP AT ALL. *TR
