What owners say
Rear seat belt latch plates (both driver and passenger side) retracted into the rear side paneling behind the seat. Both seat belts are now unusable. Issue occurred after rear seats were folded flat and then returned to upright position. Vehicle does not have dynamic locking tongue latch plates in the rear seats. MB dealership and MB customer care both claim that vehicle is not under the federal safety agency recall 18V‑177 despite fitting the issue description, make & model, and production date.
The seat belt latch plates (the parts that insert into the buckles) for the outboard rear seats may retract into the interior paneling, preventing the occupants from being able to use the seat belts. If the rear seat passengers cannot fasten their seat belts, they have an increased risk of injury in the event of a crash.
Driver's seatbelt is latched and it shows as unlatched with tge seatbelt sensor going off. On the dashboard it also shows the airbag icon
Back seat passenger seatbelt will occasionally not latch.
The seat belt latch plates (the parts that insert into the buckles) for the rear seat retracted into the interior paneling, preventing the occupant from being able to use the seat belt. (refer to similar recall # 18v177000). Although there was a recall for the same issue, my VIN was not included. I was ultimately able to fix it on my own by fishing it out from the interior panel with my fingers which was difficult to do. It is not clear how it happened, but we think it was after the rear seat was down and when it was returned to it's normal position it pushed the latch plate into the interior. We contacted our local mb dealership and were told nothing could be done since the VIN was not on the recall even though we had the same exact issue as the recall.
