2008 CADILLAC DTS Complaints

THE CAR GIVES OFF FALSE OIL PRESSURE INFORMATION ON CARS MESSAGE CENTER. I REPLACED THE SENSOR AS DISCRIBED, VERIFIED MY OIL LEVEL, CLEANED THE CONNECTOR TO OIL PRESSURE SENSOR AND STILL EVERY 2 OR 3 MINTUES I GET ENGINE OIL PRESSURE LOW, STOP VEHICHLE. WHEN I STOP THE OIL LEVEL IS GREAT AND THE OIL IS VERY CLEAN. THIS HAS BEEN GOING ON FOR OVER 3 MONTHS. IF THE OIL PRESSURE WAS LOW THE ENGINE WOULD HAVE SIEZED UP BY NOW. THIS IS ONGOING ISSUE WITH THESE 08 CADILLAC DTS 4.7L NORTHSTAR ENGINES.

REAR PASSENGER FUSE BLOCK (P/N 19116816) GETS MELTED BY A FAULTY FUSE PUMP RELAY BURNING UP DUE TO A FAULTY DESIGN WITHIN THE FUEL PUMP SYSTEM. FUEL PUMP PUTTING A LOT OF RESISTANCE ON THE WIRING, RELAY WON'T BLOW, BUT IT MELTS. WITHOUT CORRECTING THIS, THE FUSE BOX WILL BE AFFECTED ONCE THE FUSE PUMP RELAY OVERHEATS AND EVENTUALLY MELTS AND BURNS. CAR WAS STATIONED. THIS IS UNSAFE BY ANY MEANS. THE FIRE COULD HAVE SPREAD AND CAUSED THE SEATS TO BURN AND WORSE, IT'S RIGHT BY THE GAS TANK.

MY 2008 CADILLAC DTS WOUDL NOT START, I FOUND THE FUEL PUMP RELAY TO BE BURNT. I REPLACED AND WAS ABLE TO DRIVE FOR 150 MILES, SAME THING HAPPENED AGAIN. REPLACED THE RELAY AGAIN IN ORDER TO GET HOME. I THEN REPLACED THE FUEL PUMP, SAME THING HAPPENED. THEN I RESEARCHED THAT THIS IS A KNOWN PROBLEM AND THAT THE FUSE BOX UNDER THE REAR SEAT NEEDS TO BE REPLACED. FUEL PUMP RELAY KEEPS BURNING UP UNDER THE REAR SEAT, POTENTIAL FIRE HAZARD. IT WILL CONTINUE TO BURN UNTIL YOU REMOVE IT.

2008 CADILLAC DTS (100K MI) WAS PARKED AND ENGINE WOULD TURN OVER BUT NOT START. I DETERMINED THAT THERE WAS NO FUEL TO ENGINE BY CHECKING SCHRADER VALVE ON FUEL RAIL. PROCEEDED TO CHECK FUEL PUMP (FP) FUSE (OK) AND FP RELAY (BURNED ON PIN 30 ALONG WITH FUSE BLOCK). REPLACED FP RELAY; HOWEVER, AFTER A FEW MINUTES FROM VEHICLE START, THE RELAY HEATS TO ABOUT 200 DEGREES F. AFTER READING SEVERAL FORUMS, THIS IS NOT UNCOMMON: IT APPEARS THE FUSE BLOCK (UNDER REAR SEAT ). IS DEFECTIVE. I HAVE ORDERED GM BLOCK 19116810 WHICH APPARENTLY SUPERSEDES THE ORIGINAL FACTORY GM BLOCK 13599106. THIS PROBLEM CLEARLY POSES MANY SAFETY ISSUES: FIRE, ENGINE SHUT DOWN WHILE DRIVING, ETC. GM NEEDS TO TAKE OWNERSHIP OF THIS PROBLEM. MOREOVER, I HAVE ALSO EXPERIENCED THE BURNED OUT CONNECTOR (UNDER PASSENGER SEAT) FOR THE HEATED SEATS. FORTUNATELY, I DID NOT HAVE THE HEATED WINDSHIELD WASHER OPTION WHICH ALSO EXPERIENCED ELECTRICAL ISSUES. SHAME ON GM FOR NOT CORRECTING THESE ENGINEERING DESIGN DEFECTS. SAFETY SHOULD BE PARAMOUNT WITH THESE TYPES OF ISSUES ON YOUR VEHICLES ESPECIALLY YOUR PREMIER BRAND (CADILLAC).

TL* THE CONTACT OWNS A 2008 CADILLAC DTS. THE CONTACT STATED THAT THE WINDOW WASHER FLUID WAS LEAKING AND COULD POTENTIALLY SHORT OUT THE OTHER ELECTRICAL COMPONENTS OF THE REAR WINDSHIELD WIPER. THE FAILURE WAS BURNING UP THE FUSES AND COULD CAUSE A FIRE. THE VEHICLE WAS EXPERIENCING THE SAME FAILURE AS LISTED IN NHTSA CAMPAIGN NUMBER: 08V441000 (ELECTRICAL SYSTEM). THE CONTACT SPOKE WITH BRITAIN CHEVROLET CADILLAC (4495 INTERSTATE HWY 30, GREENVILLE, TX 75402, (903) 274-4401) AND WAS INFORMED TO BRING IN THE VEHICLE. THE CONTACT WOULD BE CHARGED FOR THE REPAIRS. THE MANUFACTURER WAS NOT CONTACTED. AN INDEPENDENT MECHANIC DIAGNOSED THAT THE ENTIRE FUSE BOX AND HARNESS LOCATED UNDER THE BACK SEAT NEEDED TO BE REPLACED. THE MECHANIC WOULD NOT PERFORM ANY REPAIRS DUE TO A POTENTIAL FIRE. THE FAILURE MILEAGE WAS 200,000.

THE CHECK ENGINE CODE SHOWED THE INTERNAL POWER MODULE FAILURE CAUSED THE ENGINE TO SHUT DOWN WHILE TRAVELING AT A HIGH RATE OF SPEED. THIS WAS WITHOUT WARNING AND MADE THE CAR'S POWER BRAKES AND STEERING TO BECOME ALMOST IMPOSSIBLE TO STEER AND BRAKE THE CAR BY MY WIFE. I TOOK THE CAR TO THE DEALER WHO TOLD ME WITH THE CHECK ENGINE OFF THEY SAID I HAD TO DRIVE THE CAR UNTIL THE CHECK ENGINE LIGHT CAME BACK ON. WHILE DRIVING THE CAR THE CHECK ENGINE LIGHT CAME ON WHILE I WAS IN HEAVY TRAFFIC AND AGAIN AN ACCIDENT WAS NARROWLY AVOIDED. THE DEALER DID A DIAGNOSTIC CHECK AND REPLACED THE MODULE PLUS THE COMPUTER AT A COST OF $750. THIS IS THE NINTH CADILLAC I HAVE OWNED SINCE 1980 WHEN I PURCHASED A SEVILLE WITH A DIESEL ENGINE AND THIS IS THE FIRST THAT HAD A DEFECTIVE POWER MODULE AND COMPUTER. THIS WAS A SAFETY HAZARD AND BOTH CADILLAC AND I WERE LUCKY THAT THERE WAS NO ACCIDENT WITH INJURIES. NOW WITH THE PROBLEM CORRECTED MY WIFE IS HESITANT ABOUT DRIVING AFTER THE CLOSE CALL SHE HAS EXPERIENCED. SHE ALWAYS INSISTED ON DRIVING A CADILLAC BECAUSE OF THEIR SAFETY RATING AND BECAUSE THEY WON THE MALCULAM BALDRIDGE QUALITY AWARD BACK IN THE 1980'S. I THINK A RECALL TO REPLACE THOSE MODULES AFTER HIGH MILEAGE OF AT LEAST 65K MILES. MY 2008 CADILLAC DTS MILEAGE INDICATOR SHOWS 84,000 MILES.

THE DEALER STATED THAT FURTHER REPAIRS WOULD REQUIRE THE MOTOR TO BE REPLACED. THE CONTACT HAD THE OIL PAN, OIL HOUSING, AND VALVE COVERS REPLACED; HOWEVER, THE FAILURE RECURRED. THE FAILURE MILEAGE WAS 99,000.
