The National Highway Traffic Safety Administration (NHTSA) has denied a petition from Aldelberto A. Cordova requesting an investigation into an alleged defect in the 2023 Mercedes-Benz GLC300's 48-volt system, which reportedly caused warning lights to illuminate and led to starting issues. After reviewing the petition and information from Mercedes-Benz, NHTSA concluded that the problems may be linked to a software error in a different component, the Central Powertrain Controller (CPC), which is already being addressed through a service campaign by Mercedes-Benz. NHTSA found no grounds for a safety defect investigation at this time, but will continue to monitor any new safety information.
Simple Explanation
The U.S. car safety agency, which checks if cars have problems, looked into a complaint about a special battery in a 2023 Mercedes car that made warning lights turn on and stopped the car from starting. After checking it out, they found it wasn't a big safety problem since Mercedes is already fixing something else that might be the cause, and they'll keep an eye on the situation.
