What's wrong?
The front axle electric drivetrain on the 2022 Mercedes-Benz Eqb 300 4MATIC and Eqb 350 4MATIC helps send electric motor power to the front wheels. Inside that unit, a welded spur gear transfers rotation through the drive system. The park pawl is the parking lock that helps hold the vehicle when Park is selected.
In these vehicles, the spur gear material did not meet Mercedes-Benz specifications because of a supplier production deviation. Excessive material hardness can break the weld on the spur gear. A broken weld can affect front drivetrain function and has been linked to a park pawl malfunction, which is why the recall is tied to the federal theft protection standard.
There is no warning sign before failure. Once the issue occurs, the driver can hear loud, clear rattling noises while driving or while changing gears.

What happens at the repair
At the dealer, a Mercedes-Benz technician replaces the front axle electric drivetrain, including the improperly welded spur gear assembly identified in the recall. The replacement parts and labor are free under the recall, and the repair is available now. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty.
