During tight, slow speed turning, a rubbing noise can sometimes be heard from the rear of the car. This noise is likely coming from the clutches in the limited slip differential. If the noise persists, the differential fluid can be replaced with a special oil available from BMW. On higher mileage vehicles, this noise may never be eliminated unless the differential is replaced.

In a crash that deploys the driver's front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front driver's air bag module free of charge to correct the concern.

Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. BMW dealers will replace the affected airbag inflator modules to correct this concern.

Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.

I have a 4 door M3 with 225K miles on it. You would never be able to tell it has that kind of mileage. It still looks and drives like new. I am very impressed with the build quality of this car. No problems at all!

What a fun car to drive! Over 80K miles on our M3 and absolutely no problems. We have a fantastic local auto shop, Phaedrus, here in San Francisco to thank for the great experience. The car gets relatively good gas mileage too. It's too bad BMW isn't making 4-door M3s anymore.

1995 M3 133,000 miles. You know you have a great car when people still ask do you want to sell it? Have replaced exhaust system, needs minor body work a little rust hear and there, but still a great looking/handling car. Could never sell it!
