DURAMAX LMM DIESEL ENGINE HAD ALL 8 GLOW PLUGS FAIL ONE AT A TIME. REPLACEMENT GLOW PLUGS FROM GM HAVE A HIGHER VOLTAGE RATING ON THEM INDICATING GM WAS AWARE THESE WILL ALL FAIL IN TIME. THE ORIGINAL GLOW PLUGS VOLTAGE RATING MADE THE ENGINE START QUICKER LESS TURNOVERS AT THE EXPENSE OF THE OWNER WHO HAD TO REPLACE ALL THE ORIGINAL GLOW PLUS AS THY FAILED AFTER THE WARRANTY PERIOD. FEW FAILED DURING WARRANT AS OTHER REPORTED AND MOST FAILED MONTHS TO YEARS AFTER THE WARRANTY. IN M CASE THEY ALL FAILED AT YEAR 7 OF OWNING THE TRUCK AND ALL FAILED OPEN DUE TO THIS OVER VOLTAGE THAT GM CORRECTED IN THE REPLACEMENT GLOW PLUG. REPAIR WAS NOT CHEAP AND COULD LEAVE YOU STRANDED AS THE GLOW PLUGS FAIL AND ARE NEEDED TO START A COLD MOTOR IN A COLD CLIMATE. GM SHOULD REPLACE OR REIMBURSE OWNERS FOR THESE KNOW TO FAIL GLOW PLUGS. ORIGINAL GLOW PLUG VOLTAGE RATING 4.72V, REPLACEMENT GLOW PLUG RATING 4.85V. DEFECTIVE GLOW PLUGS CAUSES CHECK ENGINE LIGHT TO COME ON AND SETS PCM CODES AS WELL AS HARD STARTING AND EXCESSIVE CRANKING TO START. UPON START ENGINE COULD BE VERY ROUGH AS IT RUNS WITHOUT THE CYLINDER THAT HAS THE FAILED GLOW PLUGS.

GM NEEDS TO GET THERE STUFF TOGETHER AND GET THESE SAME REPETITIVE PROBLEMS FIXED ON THESE TRUCKS BECAUSE ITS THE SAME ISSUES OVER AND OVER AND OVER AGAIN DATING BACK TO THE EARLY 2000'S....

HAD EXHAUST LEAK FIXED BY DEALER SHIP ON 7/02/2010 COWORKER SAID HE COULD SMELL EXHAUST IN CAB THAT'S WHY I TOOK IT IN I COULD NOT SMELL IT. I HAVE HAD A LOT OF TROUBLE WITH EXHAUST SYSTEM FILTER LIGHT COMING ON WITH ENGINE POWER REDUCED. TAKING BACK TO DEALER SHIP. THEY SAID IT NEEDS TO BE PUT IN REGEN MODE MANUALLY, ON 12/17 2012 IS STARTED TO PASS OUT ON ROAD DOING 35MPH STARTED TO LOOSE VISION, HEADACHE, DIZZY FELT LIKE MY HEART POUNDING IN MY CHEST AND THAT'S NOT ALL MORE TO LIST. BUT STARTED GO TO DOCTORS ON MY SYMPTOM'S FOR OVER A MONTH TAKING SICK TOME AND VACATION TIME. WHEN I REALIZED EVERY TIME I GOT IN MY WORK TRUCK IT ALL STARTED OVER AGAIN. SO TOOK BACK TO DEALER FOR EXHAUST LEAK AND THEY SAID WAS LEAKING AT TURBO AND DOWN PIPE. SAID THEY FIXED IT BY TIGHTENING CLAMP. GOT DOWN THE HWY 15 MILES AND STARTED HAPPENING AGAIN. I ROLLED THE WINDOWS DOWN AND DROVE HOME BLOOD PRESSURE 170/110 THAT'S ANOTHER THING IT DOES. MY BOSS TOOK IT IN TO A DIESEL TRUCK SPECIALIST AND THEY SAID THE DOWN PIPE IS CRACKED AND LEAKING AND ADVISED TO FIX OR DRIVE IT WITH THE WINDOWS DONE. THEY STARTED TO SEND IN ALL OUR LOCAL TRUCKS TO GET TESTED AND WE FOUND 5 TRUCKS LEAKING. I'M SURE THERE ARE A LOT MORE OUT THERE. WE HAD ANOTHER GUY CRASH HIS TRUCK FROM PASSING OUT AT THE WHEEL BEFORE I FOUND THE DEFECT IN THE TRUCK. NOW THE COMPANY KNOWS WHY HE CRASHED. THIS ISSUE IS IN 2007 AND 2008 MODELS DIESELS. *TR

DURING THE WINTER HERE IN NORTHERN OHIO I HAVE BEEN EXPERIENCING A REDUCED POWER MODE IN MY CHEVY DIESEL POWERED TRUCK. IT HAS HAPPENED REPEATEDLY,ALMOST DAILY, AND ON FRIDAY, MAR 20TH, WHILE DRIVING ON THE FREEWAY THE TRUCK UNEXPECTEDLY WENT INTO THIS REDUCED POWER MODE TWICE AND DROPPED FROM 65 MPH TO LESS THAN 40 MPH, ALMOST CAUSING A CRASH BECAUSE OF THE SUDDEN DECELERATION IN ONE INSTANCE. I HAVE BEEN TO THE DEALERSHIP TWICE NOW OVER THIS ISSUE, IN BOTH CASES THEY SAID IT WAS MY AFTERMARKET AIR INTAKE PRODUCT AND IT'S SUPPOSED FOULING OF A KEY ENGINE SENSOR, THE MAF SENSOR. THEY BLAMED OIL FROM THE AIR FILTER FOULING THE SENSOR, AND YET THE AIR FILTER WAS THERE AND THERE WAS NO SIGN OF OIL SEEPAGE OR FOULING OF THE SENSOR. SINCE THEN I HAVE, AT MY EXPENSE, REPLACED THE AIR INTAKE SYSTEM BACK TO FACTORY AND THE MAF SENSOR, AND ALL THAT WAS BEFORE FRIDAY WHEN I ALMOST GOT HIT BY A SEMITRUCK. I HAVE RESEARCHED THE INTERNET, CONSULTED WITH TWO AFTERMARKET AIR INTAKE MANUFACTURERS AND HAVE DETERMINED THAT THIS ISSUE IS NOT WHAT HAS BEEN BLAMED TO DATE BUT SOMETHING ELSE FAULTY ON MY TRUCK. EITHER IN THE WIRING HARNESS AFFECTING SENSOR OUTPUT OR A DIFFERENT SENSOR THAT WORKS IN CONJUNCTION WITH THE ONE SENSOR THAT THE DTC SAYS IS AT FAULT. THERE HAS BEEN ISSUED TSB'S ON THIS ENGINE FAMILY RELATING TO MY ISSUE, GMC IS AWARE THAT THERE EXISTS AN ISSUE, AND YET I HAVE TO PAY OUT OF POCKET FOR REPAIRS AND PARTS AND LABOR FOR SOMETHING THAT SHOULD HAVE BEEN RESOLVED THE FIRST TIME UNDER WARRANTY. THE DTC IS P0102, MAF SENSOR LOW INPUT, THE SENSOR I REPLACED LOOKS IDENTICAL TO THE ONE I PUT IN, NO SIGNS OF FOULING. I EVEN AT ONE POINT PURCHASED A MAF SENSOR CLEANER MADE BY CRC, USED IT ACCORDING TO DIRECTIONS AND STILL GOT THE DTC, THE REDUCED POWER MODE AND A CHECK ENGINE LIGHT. THE TRUCK WILL RESUME NORMAL OPERATING AFTER 15 TO 20 MINUTES, BUT THEN WILL FAULT OUT AGAIN SOON AFTER OR ON THE NEXT RESTART. NO ISSUE LAST WINTER, EVEN W/ THE AFTERMARKET AIR SYSTEM. *TR
