On certain vehicles, the rear passenger seat belts may contain defective automatic locking retractors (ALR). As a result, the seat belts may not properly lock to secure a child seat.
Safety Risk
A seat belt that is used to secure a child restraint but is not properly locked could increase the risk of injury in a crash.
Corrective Actions
Porsche will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the rear seat belt(s).
