FIRST NOTICED THE RATTLE WHILE DRIVING THE CAR. EVERYTIME SUBSEQUENTLY AFTER THAT WHENEVER I TURNED THE CAR ON I WOULD HEAR A LOUD RATTLING NOISE UNDER THE HOOD. CAR IS A 2009 MINI COOPER S WITH 38,005 MILES ON IT. TIMING CHAIN AND ASSEMBLY NEEDS TO BE REPLACED. DEALERSHIP QUOTED ME $5,000 TO REPAIR. THE CAR WAS JUST OUT OF WARRANTY AND MINI USA DIDN'T WANT TO HELP OUT WITH REPAIR COST. SEEMS LIKE A LOTS OF THESE FAIRLY NEW CARS HAVE THIS ISSUE. DEALERSHIP THAT QUOTED ME SAID THEY HAD 5 THEY WERE WORKING ON JUST THIS WEEK. THEY EXPECTED MINI TO ISSUE A RECALL BUT WERE SURPRISED THEY HADN'T.

MINI RELEASED A SERVICE BULLETIN (CAMPAIGN: SIM 11 02 12) REGARDING FAULTY TIMING CHAIN TENSIONER. AT APPX. 40K MILES, MY COOPER S WAS TAKEN IN FOR SERVICE AND IT WAS REPORTED THERE WAS A "RATTLE" IN THE FRONT OF THE ENGINE. THE DEALERSHIP REPLACED THE TENSIONER UNDER WARRANTY. NOW THE SAME ISSUE HAS OCCURRED. I AM BEING TOLD THE ENTIRE TIMING CHAIN ASSEMBLY NEEDS REPLACEMENT AT AN APPROXIMATE COST OF $3K. MINI HAS OFFERED TO PAY 1/2 THE COST. THERE IS NO EXPLANATION WHY THE REPAIR IS NOT COVERED UNDER 2 YEAR REPLACEMENT TENSIONER WARRANTY; SINCE THIS ORIGINAL ISSUE WAS ONLY PARTLY ADDRESSED WHILE IN 50K CAR WARRANTY. MY MINI NOW HAS 77K. ONCE WARRANTY REQUEST IS SUBMITTED FROM DEALER TO MINI CORPORATE, DECISION IS FINAL. THERE IS NO APPEAL. FAILURE TO PERFORM SERVICE WILL RESULT IN ENGINE FAILURE IN NEAR FUTURE. *TR

12/14/12: I DROVE HOME FROM WORK. I HAD NO PROBLEMS DRIVING, BUT HEARD A BIT OF A COLD START KNOCK. 12/15/12: CAR DIDN'T START IN THE MORNING. I IMMEDIATELY GOT THE CAR TOWED TO HERB CHAMBERS IN BOSTON, WHERE I HAD EXCLUSIVELY TAKEN IT TO EVERY MAINTENANCE CHECK-UP AND ISSUE I HAD SINCE I PURCHASED IT NEW AT THE SAME LOCATION, EVEN AFTER MY WARRANTY HAD EXPIRED. 12/16/12: HERB CHAMBERS PERFORMED A DIAGNOSIS FOR $135, AND SAID THAT THE TIMING CHAIN WAS BROKEN, WHICH WOULD COST $2,500 TO FIX. HOWEVER, THEY ALSO SAID THAT OTHER ENGINE PARTS MAY BE BROKEN, BUT THEY WOULDN'T KNOW UNTIL THEY STARTED WORKING ON THE TIMING CHAIN. AS YOU CAN SEE, I WAS NOT HAPPY AT ALL WITH THIS INCONCLUSIVE DIAGNOSIS. DO I PAY $2,500 FOR THEM TO THEN TELL ME IT ACTUALLY NEEDS A NEW ENGINE FOR CLOSE TO $10,000, OR DO I TOW IT ELSEWHERE? 12/17/12: TOWED CAR TO GERMAN PERFORMANCE SERVICE FOR A MORE COMPLETE DIAGNOSIS, WHICH SHOWED THAT THE TIMING CHAIN AND TENSIONER WERE BROKEN, AS WELL AS MOST VALVES AND OTHER ENGINE PARTS. WE CONCLUDE THAT IT IS CHEAPER TO REPLACE THE ENTIRE ENGINE ($3,213 + $1,980 OF LABOR = $5,193) THAN TO FIX EVERYTHING INDIVIDUALLY, WHICH WOULD BE MORE LABOR INTENSIVE. 12/21/12: I CONTACTED MINI USA TO INFORM THEM ABOUT MY SITUATION AND HOW UNPLEASED I WAS WITH HERB CHAMBER'S EXTREMELY VAGUE DIAGNOSIS, AS WELL AS MINI'S MAJOR TIMING CHAIN FLAW. MINI USA COMPLETELY IGNORED MY REQUEST FOR THE SOLE REASON THAT I TOOK MY CAR TO A 3RD PARTY MECHANIC. THEY SAID THAT IF I HAD STAYED AT THE DEALER (EVEN THOUGH THEY GAVE ME AN INCOMPLETE DIAGNOSIS), THAT THEY MAY HAVE HELPED ME OUT. 12/30/12: I CONTACTED HERB CHAMBERS BOSTON WITH THE SAME CONCERNS. THEY UNDERSTOOD MY POINTS, BUT SAID THAT UNFORTUNATELY THEY CANNOT FORCE THE MANUFACTURER TO DO ANYTHING THEY DO NOT WANT TO DO. AS A SMALL GESTURE, THEY DID GIVE ME BACK WHAT THEY CHARGED ME FOR THEIR INITIAL DIAGNOSIS ($135). *TR

Status: closed (inferred from source dates) · Engine And Engine Cooling
In a January 10, 2012 letter to NHTSA, BMW of North America, LLC. (BMW) submitted a Defect Information Report (DIR) identifying a defect in the electric auxiliary water pump in approximately 88,911 model year (MY) 2007-2011 Mini Cooper vehicles manufactured from November 14, 2006 through January 18, 2011 (Recall 12V-008).According to BMW, the auxiliary water pump on vehicles equipped with 4-cylinder turbocharged engines may overheat.Electro-migration can cause the pump electronic circuit board to overheat resulting in smoldering of the water pump. If smoldering occurs, it may lead to an engine compartment or vehicle fire.The pump supplier, Pierburg Pump Technology GmbH, redesigned the pump to address factors that may contribute to circuit board overheating.The redesigned pumps were completely implemented in production vehicles by January 2011.Recall 12V-008 was the third recall initiated by BMW to address electric auxiliary water pump fires in vehicles equipped with Pierburg pumps.In two October 20, 2011 letters to NHTSA, BMW submitted DIRs for similar auxiliary water pump defect conditions in approximately 32,084 MY 2008-2011 BMW 5-Series, 7-Series, X5 and X6 models equipped with 8- and 12-cylinder engines and manufactured from May 2008 through December 2010 (Recall 11V-521); and for approximately 589 MY 2010 Rolls-Royce Ghost vehicles manufactured from September 2009 through September 2010 (Recall 11V-522).In three separate April 5, 2012 letters to NHTSA, BMW submitted amendments to Recalls 11V-521, 11V-522 and 12V-008.The amendments all described a common defect condition related to a manufacturing process deviation in a certain production range of the redesigned Pierburg water pumps that could result in cracks in the pump housing, which may allow coolant to enter and contact the pump?s circuit board.BMW indicated that further analysis identified a specific machine process error at the sub-supplier that manufactures the water pump housing.Pump housing cracks may cause the circuit board to overheat and lead to smoldering of the water pump.Recall 12V-008 was, thus, amended to include approximately 1,457 MY 2011 Mini Cooper vehicles manufactured from March 31, 2011 through April 22, 2011, when pumps manufactured with the suspect manufacturing process may have been used in vehicle assembly.The amendment to Recall 11V-521 was assigned a new recall number, Recall 12V-161, and covered approximately 2,846 MY 2011-2012 BMW 5-Series, 6-Series, 7-Series, X5, and X6 vehicles manufactured from April 1, 2011 through August 1, 2011.The amendment to Recall 11V-522 was assigned a new recall number, Recall 12V-166, and covered approximately 69 MY 2011 Rolls-Royce Ghost vehicles manufactured from April 7, 2011 through June 2, 2011.The Office of Defects Investigation (ODI) analyzed complaint data provided by BMW as well as complaints submitted to ODI from consumers. In total, there were 30 unique Mini Cooper reports indicating engine fire.In addition, BMW provided warranty data showing 493 claims for replacement of the subject component on Mini Cooper vehicles.Owners of the recalled vehicles are notified to take their vehicle to a BMW dealer, who will replace the auxiliary water pump to prevent any incidents related to this issue.This preliminary evaluation is closed.The ODI reports cited above can be viewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers (ODI Nos.):10286597, 10286663, 10289793, 10310677, 10314796, 10342365, 10394808, 10394192, 10403982, 10418325, 10422646, 10429003.

If smoldering occurs, it may lead to an engine compartment or vehicle fire.The pump supplier, Pierburg Pump Technology GmbH, redesigned the pump to address factors that may contribute to circuit board overheating.The redesigned pumps were completely implemented in production vehicles by January 2011.Recall 12V-008 was the third recall initiated by BMW to address electric auxiliary water pump fires in vehicles equipped with Pierburg pumps.In two October 20, 2011 letters to NHTSA, BMW submitted DIRs for similar auxiliary water pump defect conditions in approximately 32,084 MY 2008-2011 BMW 5-Series, 7-Series, X5 and X6 models equipped with 8- and 12-cylinder engines and manufactured from May 2008 through December 2010 (Recall 11V-521); and for approximately 589 MY 2010 Rolls-Royce Ghost vehicles manufactured from September 2009 through September 2010 (Recall 11V-522).In three separate April 5, 2012 letters to NHTSA, BMW submitted amendments to Recalls 11V-521, 11V-522 and 12V-008.The amendments all described a common defect condition related to a manufacturing process deviation in a certain production range of the redesigned Pierburg water pumps that could result in cracks in the pump housing, which may allow coolant to enter and contact the pump?s circuit board.BMW indicated that further analysis identified a specific machine process error at the sub-supplier that manufactures the water pump housing.Pump housing cracks may cause the circuit board to overheat and lead to smoldering of the water pump.Recall 12V-008 was, thus, amended to include approximately 1,457 MY 2011 Mini Cooper vehicles manufactured from March 31, 2011 through April 22, 2011, when pumps manufactured with the suspect manufacturing process may have been used in vehicle assembly.The amendment to Recall 11V-521 was assigned a new recall number, Recall 12V-161, and covered approximately 2,846 MY 2011-2012 BMW 5-Series, 6-Series, 7-Series, X5, and X6 vehicles manufactured from April 1, 2011 through August 1, 2011.The amendment to Recall 11V-522 was assigned a new recall number, Recall 12V-166, and covered approximately 69 MY 2011 Rolls-Royce Ghost vehicles manufactured from April 7, 2011 through June 2, 2011.The Office of Defects Investigation (ODI) analyzed complaint data provided by BMW as well as complaints submitted to ODI from consumers. In total, there were 30 unique Mini Cooper reports indicating engine fire.In addition, BMW provided warranty data showing 493 claims for replacement of the subject component on Mini Cooper vehicles.Owners of the recalled vehicles are notified to take their vehicle to a BMW dealer, who will replace the auxiliary water pump to prevent any incidents related to this issue.This preliminary evaluation is closed.The ODI reports cited above can be viewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers (ODI Nos.):10286597, 10286663, 10289793, 10310677, 10314796, 10342365, 10394808, 10394192, 10403982, 10418325, 10422646, 10429003.
