2025 MERCEDES-BENZ Gls 450 4MATIC

We recently noticed visible damage to one of the seatbelts in our 2025 Mercedes-Benz GLS450. The affected component is the seatbelt webbing. The belt has visible fraying and pulled/cut fibers along the edge in two separate spots near the area where the belt retracts. The vehicle is very new, and the damage appears abnormal for a safety-related component. The damage is localized near the belt path/retractor area, and we are concerned it may be related to an issue with the seatbelt path, retractor mechanism, surrounding trim, alignment, or another defect in the restraint system. The component is available for inspection upon request. This creates a safety concern because the seatbelt is a critical occupant restraint system. If the webbing fibers are damaged, the seatbelt may not perform as intended in a crash or sudden stop. We are currently avoiding use of that seating position until the issue is inspected and resolved. The problem has been brought to the attention of a Mercedes-Benz dealer. The dealer quoted approximately $2,250 to replace the affected seatbelt and indicated that it would not be covered under warranty. To our knowledge, the dealer has not yet fully inspected the seatbelt mechanism, belt path, surrounding trim, or retractor area to determine whether the damage is related to a defect or abnormal condition in the vehicle. The vehicle/component has not yet been inspected by the manufacturer, police, insurance representatives, or an independent service center. We are requesting further inspection by Mercedes-Benz because this is a safety-related component on a new vehicle. There were no warning lights, dashboard messages, or other symptoms before we noticed the seatbelt webbing damage. The first symptom was the visible fraying/pulled or cut fibers on the seatbelt webbing. The exact cause is UNKNOWN.
