TOOK VEHICLE IN FOR INSTALLATION OF THE HEAT SHIELD FOR TURBO FEED LINE. THIS IS A RECALL AND NEWLY INSTALLED PART TO PROTECT THE TURBO FEED LINE DUE TO OVERHEATING. ONCE IT WAS INSTALLED I WAS INFORMED THAT THE TURBO LINE IS FAILING AND THE DEALER WANTS TO CHARGE ME $1500 TO REPAIR THE LEAKING LINE.

ENGINE ALL OF A SUDDEN STARTS MAKING A RATTLING NOISE. TOOK IT IN TO DEALER, TIMING CHAIN GUIDES HAD BROKEN AND CHAIN WAS STRETCHED. WAS INFORMED THERE WAS A MINI CAMPAIGN ABOUT THIS BUT MY VEHICLE WAS NOT INCLUDED. EXPENSIVE REPAIR AND POTENTIALLY DANGEROUS SITUATION IF CHAIN HAD BROKEN. WAS INFORMED AFTER WORK WAS DONE THAT CLUTCH WAS BAD AS WELL. HAD DRIVEN THE VEHICLE THE DAY BEFORE WITHOUT ISSUE BUT AFTER ONLY 10 MILES FROM THE DEALERSHIP CAR WOULD NOT MOVE FROM STOPPED SINCE CLUTCH WOULD NOT ENGAGE. EXTREMELY EARLY FOR THIS AMOUNT OF REPAIRS TO BE NEEDED, I QUESTION THE DURABILITY OF THESE PARTS AND THIS BRAND. BOTH OF THESE SUDDEN WEAR FAILURES COULD HAVE BEEN EXTREMELY DANGEROUS IF THEY HAD OCCURRED ON THE HIGHWAY. *JS

DRIVING ON 405 FWY IN SOUTHERN CALIFORNIA TURNING OUT OF FREEWAY OFF RAMP IN THE POURING RAIN. THE CAR DEAD STOPPED. VERY DANGEROUS, CARS COMING OFF FREEWAY BEHIND ME WAS A 911 SITUATION. AFTER SOMEONE PUSHED ME OFF TO THE SIDE OF THE ROAD HAD CAR TOWED. NO ENGINE LIGHT WARNING TO INDICATE PROBLEM OF TENSIONER (TIMING CHAIN BREAKAGE). ENTIRE ENGINE WAS REPLACED/REBUILT BECAUSE OF EXTENSIVE DAMAGE TO ENGINE. BMW APPARENTLY IS AWARE OF THE TIMING CHAIN DEFECT AND HAS NOT ISSUED SERVICE BULLETIN OR RECALL. I'M HEARING THERE IS A CLASS ACTION SUIT BECAUSE OF THE MANY COMPLAINTS. THE FACT THAT I COULD HAVE VERY EASILY BEEN KILLED OR SERIOUSLY INJURED IS WHY I AM ISSUING A COMPLAINT (NOT TO MENTION MY BILL FOR $6200.00 I HAVE ON MY CREDIT CARD) AND THE THREE WEEKS IT TOOK TO FIX.

MY CAR HAS BEEN LEAKING OIL AND THE DEALERSHIP DETERMINED IT WAS DUE TO THE TIMING CHAIN TENSIONER. THEY ARE CHARGING $357.98 TO HAVE IT FIXED. MY CAR WAS PURCHASED BRAND NEW AND HAS ONLY 50,000 MILES ON IT. AS SOON AS MY 4-YEAR WARRANTY EXPIRED, MY CAR HAS BEEN IN THE SHOP MULTIPLE TIMES DUE TO ENGINE ISSUES.

COOLANT FLUSH- $169.80 I USE ONLY PREMIUM GAS FOR MY CAR, PERFORM REGULAR OIL CHANGES, AND MAINTAIN MY CAR METICULOUSLY. THESE PROBLEMS SHOULD NOT BE OCCURRING AFTER 4.5 YEARS OF DRIVING. I BELIEVE THAT MINI PRODUCES FAULTY CARS THAT DO NOT LAST, HAVE ABSOLUTELY ZERO RELIABILITY, AND THEN CHARGES AN EXORBITANT AMOUNT TO FIX SOMETHING THAT SHOULD HAVE NOT BEEN BROKEN IN THE FIRST PLACE. *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.
