Example complaints

Air bags: “The contact owns a 2003 Bmw 525I. The contact stated that while starting the ignition the air bag warning light illuminated until the engine was turned off.

NHTSA complaint #10693622, filed 2015-03, 20,000 miles

Electrical system: “I was driving along the freeway when all of a sudden my car engine started to run very rough and the service engine light came on. My car have to be towed to the Bmw dealership and I was told the all of the ignition coils have to be replaced. My car then had only 29k+ miles.”

NHTSA complaint #10307921, filed 2010-02, 29,600 miles

Exterior lighting: “I have a complete failure of the passenger(right) side tail light assembly on our 2003 Bmw 525I. The tail light is connected to a wiring harness via a connector. One of the connector pins has been overheated by the electrical current and has been burnt to a crisp. This exact problem has forced Bmw to do a recall in 2011 on the 3-series of automobiles and yet they have ignored the safety of series-5 owners and have yet to issue a recall for this highly dangerous component failure. This failure causes the driver into believing that they have working turn signals when in actuality they do not. …”
