National Highway Traffic Safety Administration September 29, 2016 – Federal Register Recent Federal Regulation Documents

General Motors, LLC (GM), has determined that certain model year (MY) 2016-2017 Cadillac CTS, CT6, XTS and Escalade motor vehicles do not fully comply with paragraph S5.5.5(a) of Federal Motor Vehicle Safety Standard (FMVSS) No. 135, Light Vehicle Brake Systems. GM filed a report dated August 17, 2016, pursuant to 49 CFR part 573, Defect and Noncompliance Responsibility and Reports. GM then petitioned NHTSA under 49 CFR part 556 for a decision that the subject noncompliance is inconsequential as it relates to motor vehicle safety.

In this rulemaking action, NHTSA is finalizing procedures for obtaining an exemption from the vehicle theft prevention standard for vehicles equipped with immobilizers. An immobilizer is an anti-theft device that combines microchip and transponder technology with engine and fuel immobilizer components that can prevent vehicles from starting unless a verified code is received by the transponder. This final rule streamlines the exemption procedure for immobilizer-equipped vehicles by adding performance criteria for immobilizers. The criteria, which roughly correlate with the types of qualities for which petitioners have been submitting testing and technical design details under existing procedures, closely follow the immobilizer performance requirements in the anti-theft standard of Canada. After this final rule, it would be sufficient for a manufacturer seeking the exemption of some of its vehicles to provide data showing that the device meets the performance criteria, as well as a statement that the device is durable and reliable. Adopting these performance criteria for immobilizers bring the U.S. anti-theft requirements more into line with those of Canada.
