Consumer Description

N20 Timing Chain failure/broke. My daughter's safety was put at risk because the chain broke while she was driving on a 2 lane back road, causing the vehicle to go into limp mode. The car stopped suddenly, in the middle of the road. The problem has been confirmed at the BMW service center. We have since found out that this is a known problem that BMW North America is aware of, and several class action lawsuits have been filed. The "transmission malfunction warning" appeared on the dashboard within seconds before the timing chain failure.
