1999 BMW 5 Series

No clear pattern

1.9% of complaints about the 1999 BMW 5 Series arrived in its first year of service. That is an unusual figure for a 1999 vehicle, but with only 108 complaints on record the sample is too small to call it a pattern — the margin of error covers the range where ordinary vehicles sit. The figures below are reported without a verdict. The most-reported system is engine cooling (16 complaints), typically at 6.2 yr or about 54,750 miles.

Covers 3 variants: 528I (59), 540I (29), 540IA (11)

Complaints: 108
Median age at failure: 6.3 yr
Median mileage: 82,200 n=72
Crash / fire / tow: 12% of reports
Safety recalls: 1

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.

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.
