National Highway Traffic Safety Administration May 29, 2019 – Federal Register Recent Federal Regulation Documents

This notice sets forth the reasons for the denial of a petition submitted on August 6, 2014, by Mr. Donald Friedman to the National Highway Traffic Safety Administration's (NHTSA) Office of Defects Investigation (ODI). The petition requests that the agency commence a proceeding to determine the existence of a defect related to motor vehicle safety with respect to the rollover crash performance of the model year (MY) 2010 Chevrolet Tahoe and similarly constructed General Motors (GM) vehicles. The petition alleges that the rollover side curtain air bag system in these vehicles is defectively designed and can allow second and third row occupants to be ejected in rollover crashes. In addition, the petition alleges that the side window glass, rear seat belts, and roof structure are defectively designed. After examination of the petition and available data relating to the rollover crash performance of the subject vehicles, NHTSA does not believe that a safety-related defect currently exists in the design of the rollover side curtain air bags in the MY 2010 Chevrolet Tahoe and other similarly designed Chevrolet Tahoe and GMC Yukon vehicles. The agency has accordingly denied the petition. The petition is hereinafter identified as DP15-004.
