  • A brittle weld in the front drive unit of 283 Mercedes EQBs in the USA could break.
  • In this case, the parking lock will be disabled and the electric vehicle could roll away when it is supposedly in the park position.
  • Mercedes will contact affected owners of the 2022 EQB 300 and 350 and replace their front engines free of charge.

The owners of 283 EQBs in the U.S. can expect a letter from Mercedes on July 9 because their vehicles may have a safety defect that allows them to roll away even when supposedly in “Park.”

Mercedes first noticed the problem in June 2022 when it received complaints about drivetrain noise and vibration from EQB customers outside the US. The automaker began investigating the problem and determined that the rattling was caused by a spur gear in the front engine that could break due to a weld that was too brittle.

This could cause the differential spur gear in the front motor to rotate freely in its assembly, effectively cutting off power to the front wheels. Luckily, since the problem only affected one axle, the EQB was still able to drive with the rear engine and didn’t leave consumers stranded on the road – which is the reason for many recalls.

When Mercedes investigated the issue further, it discovered that the loss of power was not the only potential safety risk associated with this error, as the parking lock is located on the front axle of the EQB.

Therefore, if the differential spur gear is free to rotate, the pawl cannot prevent the front wheels from rotating and the electric vehicle may roll away even when in park. Although the parking brake still works, there is a risk of consumers being caught and an out-of-control vehicle is dangerous. Therefore, Mercedes is recalling the model.

The issue affects the 2022 EQB 300 and 350 models. Owners of these vehicles are asked to return their vehicle to a nearby dealer where the front electric powertrain will be replaced free of charge.

Owners can check the National Highway Traffic Safety Administration website to see if their specific model is affected by this error. You may notice a loud rattling noise while driving or shifting gears if your spur gear has already cracked.
