Recall Issued for Mercedes-Benz EQB Electric Crossovers Due to Faulty Weld in Front Axle Motor
Mercedes-Benz has announced a recall affecting approximately 300 units of the EQB, the electric version of the GLB. The recall specifically targets vehicles built during the 2022 model year that could potentially roll away while parked. The culprit behind this potential safety hazard is a faulty weld in the front axle’s electric motor.
Assigned with recall number 24V-331 by the National Highway Traffic Safety Administration (NHTSA), the recall includes 183 units of the 2022 EQB 300 and 100 examples of the 2022 EQB 350. It is important to note that front-wheel-drive EQBs and the gasoline-powered GLB are not affected by this recall. The affected crossovers were manufactured between February 18, 2022, and January 23, 2023.
Mercedes-Benz has identified a welded spur gear within the front axle’s motor as the root cause of the problem. The company explains that the weld may fail, allowing the differential spur gear to rotate freely from the differential assembly within the front axle electric drivetrain. Consequently, the mechanism’s pawl will not prevent the EQB from rolling away, even when the driver selects Park. However, using the electronic parking brake can effectively prevent the crossover from rolling off, as it engages automatically when the EQB is turned off or when the driver’s door is opened.
Additionally, Mercedes-Benz highlights that the weld failure may occur without any prior warning signs. In some cases, a failed weld can lead to loud rattling noises while driving. The company’s engineers began investigating this issue in June 2022 when they received reports from international markets outside of the United States. They discovered that the weld on the spur gear broke due to excessive material hardness. Despite this problem, the EQB can still be driven since the rear-mounted motor continues to function as intended, even if the front motor develops an issue. While Mercedes-Benz has received five warranty claims, field reports, and service reports, there have been no reported accidents, injuries, or fatalities associated with this problem.
Fortunately, the fix for this issue is relatively straightforward. As it affects 100% of the recalled EQBs, owners will need to visit an authorized Mercedes-Benz dealership where a technician will replace the front axle’s motor. To ensure that every affected owner is aware of the recall, Mercedes-Benz plans to notify them by mail before July 9, 2024.
In conclusion, Mercedes-Benz is taking proactive measures to address a potential safety concern with the electric EQB crossovers. By issuing a recall and rectifying the faulty weld in the front axle’s motor, the company demonstrates its commitment to consumer safety. It is crucial for owners of the affected vehicles to follow the instructions provided by Mercedes-Benz and schedule a visit to an authorized dealership for the necessary repairs.
