2004 BMW 6 Series common problems

The most-reported problem areas from 14 owner complaints filed with NHTSA — and what to check before you buy.

Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Seat Belts
Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
Seats
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
