Fuel & propulsion system
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 outlined in NHTSA Recall 24V331 for the 2022 EQB front axle drivetrain failure. …
Mercedes previously issued a software update for the battery fire risk, but we have received a letter more than a year later stating that this fix was not adequate. We pursued a vehicle buyback due to the safety risk this presents to my family, and Mercedes vehemently stated that the issue was resolved and the vehicle did not qualify. The vehicle is an inherent risk to my family's safety if it may just catch fire at any time.
