The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 17V627000 (AIR BAGS). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 60,000.

I was backing out of my driveway and was putting the car in Drive when the airbag located in my steering wheel deployed without a reason. The car has not been inspected by anyone as of today. I was told there was a warning but that it was not of immediate attention in November of 2024.

The contact owns a 2018 Mercedes-Benz GLC300. The contact stated while driving approximately 30 MPH, the air bag warning light illuminated. Additionally, the contact stated that he observed a rattling noise emanating from the steering column while making right turns. The vehicle was taken to an independent mechanic where it was diagnosed that the clockspring needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 72,000.

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. The contact researched online and related the failure to NHTSA Campaign Number: 19V788000 (Seat Belts) however, the model year was not included. The manufacturer was informed of the failure. The failure mileage was approximately 48,000.

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.

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

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).

Back seat passenger seatbelt will occasionally not latch.

I was involved in a minor collision with a deer. I was driving alone and the deer hit my front passenger side. The airbags deployed. The knee bag completely destroyed the flesh on my entire right shin. It is one giant open wound that will take months to heal. I am short so I sit close to the dash. Had this knee bag not deployed I would have no injuries from the incident. The main airbag caused no damage so I feel I sit far enough away from that one. I am now scared to drive a vehicle with knee bags for fear of a repeat injury. I believe the knee bag is not safe for shorter people.

TL* THE CONTACT OWNS A 2018 MERCEDES-BENZ GLC300. THE CONTACT STATED THAT THE AIR BAG WARNING LIGHT WAS ILLUMINATED AT START-UP. THE CONTACT TOOK THE VEHICLE TO MERCEDES-BENZ OF MYRTLE BEACH (936 JASON BLVD, MYRTLE BEACH, SC 29577) WHERE SHE WAS INFORMED THAT THE AIR BAG CONTROL UNIT PROCESSOR WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THE VEHICLE WAS NOT UNDER RECALL. THE FAILURE MILEAGE WAS APPROXIMATELY 57,000.

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.
