he vehicle intermittently fails to shift from Park (P) to Drive (D). Recently, the car was completely immobilized for over 6 hours because the gear would not engage, making it dangerous and unpredictable to drive. Additionally, the vehicle has experienced multiple charging failures where charging repeatedly cuts off unexpectedly. A formal diagnosis from Mercedes-Benz of Cary confirmed a front axle drive unit failure and high-voltage insulation faults, triggering codes U041A00 and P154800. Crucially, the certified technician noted a grinding noise coming from the axle drive module, which occurs specifically when slowing down. These symptoms perfectly mirror the known manufacturing defects…

This urgent safety issue with the high voltage battery on the 2022 Mercedes EQB has been known to Mercedes since at least July 2025. As of May 15, mercedes tells me I will have a repair scheduled by December 30, 2026. They offer no explanation for the delay. This is unreasonable and unacceptable. I am requesting that the NHSTA inform Mercedes that they must do better to eliminate this known fire hazard, and inform me of the penalties you can impose on Meercedes if they do not complete this recall in a timely fashion.
