I bought 2017 gls 450 in july last year 2016.the passenger seat does not move properly forward and backward.after the initial review the dealer told me it was external influence that created the problem. the motor is under the seat in the middle of the seat. in no way it could be external problem. the seat will not move in the event of accident and there could be no deploy of the airbag due to malfunction of seat.i m just worried of the safety of the family. please can u check in this matter thanks.
Headrests in the 2nd row are unsafe, in the up position it has no protection for children or adults, in the down position it pushes the neck and head of all passengers forward.
