Both the driver and passenger seatbelts have been replaced due to wear and shredding. Dealership has told us it was caused by the seatbelt extender “becoming delaminated” in both cases. This seems like a design flaw given the age and relatively low mileage (30,800). The more severe damage in the photograph is the driver’s side. The other is the passenger side that we proactively had replaced while the vehicle is still under its new vehicle warranty.
