The National Highway Traffic Safety Administration (NHTSA) has provided guidance on the requirement that manufacturers provide NHTSA with any communications to dealers, owners or purchasers about a product defect or noncompliance. NHTSA is required to post these communications, including technical service bulletins, on the agency’s www.safercar.gov website. The communications must include an index with a concise summary of the subject matter. For equipment manufacturers, the index should include descriptive information about the equipment when it is not associated with a specific vehicle make, model and model year.
