According to Nissan’s 2019 Warranty Information Booklet...None of the regulations or statutes administered by NHTSA require manufacturers to provide a lifetime warranty for seat belts. However, NHTSA has the authority to require manufacturers to replace seat belts under certain circumstances. If a vehicle or item of equipment is not more than ten years old and is determined to have a safety-related defect or fails to meet an applicable Federal motor vehicle safety standard, NHTSA can compel the manufacturer to remedy the defect or noncompliance without charge to the vehicle owner.
