Jacksonville, FL – May 4, 2022 – Daimler (OTCMKTS:DMLRY), which owns the Mercedes-Benz brand, is recalling 21,306 vehicles with an electrical installation that could overheat. This may cause a vehicle fire, increasing the risk of injury and property damage.

All models on this are so-called “mild hybrids,” meaning they have an electric motor which works together with an engine to make it more fuel-efficient. This electric motor runs on 48V and has a separate electrical installation with several ground connections to power different components in the car.
In affected vehicles, the nut that secures one of the connections under the front passenger seat might not be tightened sufficiently. This may cause the connector to overheat and catch on fire.
The component in question is the ground connection nut, with part number A0029906850.
