Defect
On certain vehicles, the attachment points for the lower universal anchorage system (for attaching a child seat) could be damaged over time. As a result, a child seat may come loose.
Safety Risk
A child seat that is not properly secured could create an increased risk of injury in a crash.
Remedy
BMW will notify owners by mail and instruct you to take your vehicle to a dealer to add a reinforcing bracket to the lower anchor bars and the vehicle body.
