12E029000 2012-08-10

Engine and engine cooling:cooling system:fan

This recall involves aftermarket parts sold by Valeo. Valeo is recalling certain engine cooling fans, part numbers 696121, 696273, and 696275, used as service replacement parts for model year 2008-2011 BMW 1-Series, 2006-2011 BMW 3-Series, 2000-2009 BMW 5-Series, 2004-2005 BMW 6-Series, and 2006-2007 BMW 7-Series vehicles. A metal-oxide semiconductor may overheat due to insufficient screwing of the semiconductor on the aluminum heat sink. This primary failure could cause adjacent components on the fan assembly motor circuit board to overheat and short.

This condition could cause the fan motor to become inoperative, or cause the motor circuit board in the assembly to overheat, potentially leading to a fire in the engine compartment.

12V126000 2012-03-26

Electrical system:12v/24v/48v battery:cables

BMW IS RECALLING CERTAIN MODEL YEAR 2004-2010 5-SERIES, MODEL YEAR 2004-2010 6-SERIES, MODEL YEAR 2006-2010 M5, AND MODEL YEAR 2007-2010 M6 VEHICLES. THE INSULATED BULKHEAD CONNECTOR FOR THE POSITIVE BATTERY CABLE MAY HAVE BEEN INCORRECTLY ATTACHED TO THE TRUNK FLOOR PANEL, WHICH CAN LEAD TO A LOOSENING OF THE BOLT CONNECTION. AS IT LOOSENS, AN INCREASE IN ELECTRICAL RESISTANCE AT THIS CABLE CONNECTION IS POSSIBLE AND COULD CAUSE THE CABLE CONNECTION TO OVERHEAT.

OVERHEATING COULD LEAD TO A FIRE, EVEN WHILE THE VEHICLE IS NOT IN USE. AS A PRECAUTION, OWNERS ARE ADVISED TO PARK OUTSIDE UNTIL THE REMEDY HAS BEEN MADE.

10V446000 2010-10-01

Service brakes, hydraulic:power assist:vacuum

BMW IS RECALLING CERTAIN MODEL YEAR 2004-2010 5-SERIES, 6-SERIES, AND MODEL YEAR 2002-2008 7-SERIES VEHICLES. A CHECK VALVE OF THE BRAKE VACUUM PUMP MAY LEAK A SMALL AMOUNT OF LUBRICATING OIL. OVER TIME THIS COULD RESULT IN CONTAMINATION OF THE BRAKE BOOSTER.

POWER ASSIST BRAKING PERFORMANCE COULD BE ADVERSELY AFFECTED. IN EXTREME CASES THERE COULD BE A COMPLETE LOSS OF POWER ASSIST BRAKING. AN UNEXPECTED REDUCTION OR LOSS IN POWER BRAKING ASSIST MAY INCREASE THE RISK OF A CRASH.

In owners’ own words

Engine cooling 2,500 mi 1.0 yr in service

DRIVING ON THE HIGHWAY AND THE ENGINE STARTED TO RUN ROUGH. THIS IS THE SECOND TIME THIS HAS OCCURRED. THE FIRST TIME THIS HAPPENED WAS IN JULY AND BROUGHT IT TO DEALER AND COULD NOT FIND PROBLEM. SECOND TIME I HAD CAR TOWED AND SAID IT WAS FAULTY IGNITION COIL. REPLACED AND SEEMS OK NOW, BUT EVERY SO OFTEN IT RUNS ROUGH FOR A FEW MOMENT. *TR

Engine cooling 15,500 mi 1.4 yr in service

1. ROUGH RIDING - LOSS OF POWER ON HIGHWAY 2. DOZENS OF TIMES OVER THE LAST FEW MONTHS. CAR HAS BEEN IN SHOP FOR TWO MONTHS OUT OF LAST 12 FOR THE SAME ISSUE. 3. BMW KEEPS TRYING DIFFERENT THINGS BUT NO FINAL FIXES AS YET. *TR

Engine cooling 3,000 mi 1.3 yr in service

WE PURCHASED A 2008 BMW 528XI AS A DEMO. IT WAS SAID TO BE CERTIFIED. IT TICKED FROM THE DAY WE PURCHASED IT. BMW SAID ALL IT NEEDED WAS AN ENGINE BLEED-DOWN. THIS WAS DONE 4 TIMES. THE VEHICLE STILL TICKED AND WE TOOK IT TO OUR TRUSTED BMW DEALERSHIP AND WA STOLD IT NEEDS A NEW CYLINDER-HEAD DUE TO A MANUFACTURER DEFECT. THE CAR ONLY HAS 3,000 MILES ON IT. THIS IS UNACCEPTABLE. THE CAR HAS BEEN IN THE SHOP SINCE MARCH 2ND, NOT EVEN BEGUN TO START THE WORK. I FEEL THE CAR SHOULD BE REPLACED AS IT IS A LEMON , AND WE DESIRE A 2009 528XI WITH THE SAME OPTIONS. *TR

Fuel system 8,000 mi 1.0 yr in service

ADDED EXXONMOBIL GAS 9/2/2008. CAR DEAD BY 9/7/2008, AFTER DRIVING APPROX. 50 MILES. THE FUEL PUMP ON THIS VERY NEW CAR HAS FAILED. THE DEALER CLAIMS THE GAS WAS BAD (SAYS ALCOHOL LEVEL TESTED TO 15%), WHILE EXXONMOBIL INSISTS THE FUEL WAS FINE AT 10% ALCOHOL, FROM THE ETHANOL. I BELIEVE THE REAL PROBLEM IS THAT THE 2008 BMW 535XI'S CAN'T HANDLE EVEN 10% ETHANOL, SO THE FUEL PUMPS ARE FAILING. *TR

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
