19E058000 2019-08-28

Steering:linkages:rod:relay:connecting

ZF Group North America Operations (ZF) is recalling certain Lemförder Steering Center Rods sold as aftermarket parts for 1996-2004 BMW 5-Series (E39) vehicles. The steering center rods may have an insufficient ball pin pull force that may allow the rods to detach from the steering knuckle.

If the steering rod detaches from the steerable wheel knuckle, it can cause sudden loss of steering control, increasing the risk of a crash.

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.

THE BMW DEALERSHIP SAYS THERE ISN'T AN ISSUE WITH THE BMW IT'S JUST PRECAUTIONARY BUT THEY STILL DON'T HAVE THE AIRBAGS IN.

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.
