2018 Mercedes-Benz GLC 300 Seat belts Problems

“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. …”

“While driving and front driver seatbelt fastened, the seat belt unfastened warning will intermittently go on and off tightening the seat belt, as if first starting the car. This has occurred for several weeks now. Per the attached recall notice, this issue has already been identified in 2018 GLC models (my VIN does not show up, however, as part of the recall), and could cause failure of the restraint system. I showed the recall notice to a Mercedes dealer, but they could not replicate the intermittent problem and did not repair it (see attached).”

“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.”

“The contact owns a 2018 Mercedes-Benz GLC300. The contact stated that when the driver's side seat belt was buckled, the seat belt alarm chimed as if the seat belt was not buckled. The contact had to buckle and unbuckle the seat belt several times before the warning chime stopped. The contact had taken the vehicle to a local dealer who diagnosed the vehicle and determined that there was no issue with the seat belt system. The vehicle was not repaired. The contact stated that the failure was intermittent. …”

“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 NHTSA recall 18V-177 despite fitting the issue description, make & model, and production date.”
