Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
