Affected vehicles were sold between 2 December 2019 to 31 January 2020.
Lodged with the Australian Competition and Consumer Commission (ACCC), the defect relates to incorrect head restraints being fitted to the vehicle’s rear bench seat.
CarAdvice has been told notches in the head restraint rods used for height adjustment are not adequately spaced, resulting in a reduced amount of height options and increased chance of an incorrect head restraint height being set.
Mercedes-Benz Australia reports that if an incorrect head restraint height is set, there is an increased risk of neck injury in the instance of an accident.
CarAdvice understands there is no risk of the head restraint separating from the seat assembly.
At time of publishing, there are no known incidents as a result of the faulty head restraints.
Mercedes-Benz is asking customers to contact a dealer for inspection and replacement of the faulty unit.
