Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2022-2023 EQB 350 4MATIC, and EQB 300 4MATIC vehicles. The bus bar in the high voltage battery may be secured with incorrect screws, which can cause the system to have a sudden loss of drive power without warning.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“The contact owns a 2022 Mercedes-Benz EQB 300 4Matic. The contact received notification of NHTSA Campaign Number: 26V073000 (Electrical System); however, the part to do the recall repair was not yet available. The contact stated that the EV battery warning light was constantly illuminated. The vehicle was taken to two dealers, including Napleton Autowerks of Indiana (1349 Indianapolis Blvd, Schererville, IN 46375), who confirmed that the parts were not yet available. The manufacturer was notified of the failure by phone and referred the contact to the dealer, who then referred the contact back to the manufacturer for assistance. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 38,000.”
“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. Despite clear connections to documented, catastrophic high-voltage safety hazards, Mercedes-Benz USA has denied warranty coverage and is demanding an outrageous repair cost of over $14,000 from the owner.”
