🚗NHTSA Denies Defect Petition for 2023 Mercedes-Benz GLC300
This notice sets forth the reasons for the denial of a defect petition, DP23-003, submitted on July 2, 2023, by Aldelberto A. Cordova (the "Petitioner") to NHTSA's Office of Defects Investigation (ODI). The petition requests that NHTSA (the "Agency") investigate an alleged defect in the "ISG 48-volt on-board electrical system," which resulted in a warning light illumination and an inability to start the Petitioner's 2023 Mercedes-Benz GLC300. The Petitioner further requested a recall for 2023 Mercedes-Benz GLC300 vehicles based on this issue. After conducting a technical review of the Petitioner's submissions, reviewing complaints related to MY 2023 Mercedes-Benz GLC300 warning light illumination as well as the inability to start a vehicle, and reviewing information provided by Mercedes-Benz regarding the ISG 48-volt system, NHTSA has concluded that the issues raised by the petition do not warrant a defect investigation at this time. Accordingly, the Agency has denied the petition.

This document revises the chest jacket and spine box specifications for the Hybrid III 5th Percentile Female Test Dummy (HIII-5F). The jacket revisions resolve discrepancies between the jacket specifications in subpart O and jackets available in the field, and ensure a sufficiently low level of variation between jackets fabricated by different manufacturers. The spine box revisions eliminate a source of signal noise caused by fasteners within the box that may become loose during sled or vehicle crash tests. This rulemaking responds to a petition for rulemaking from the Alliance of Automobile Manufacturers.
