JAKARTA - Unpleasant news came from Mercedes-Benz. The reason is, electric vehicles consisting of EQE and EQS have problems in the United States (US), triggering a recall in these two models.
Reporting from Carscoops, Wednesday, June 5, safety concerns in the battery management system's software system could trigger the high voltage system to shut down.
The recall includes a total of 14,912 vehicles in Uncle Sam's country consisting of EQE and EQS models, both sedan and SUV versions. The manufacturer says that this software defect affects 100 percent of vehicle performance.
The problem started in October 2023 when Mercedes-Benz investigated reports from dealers in Denmark regarding a high-voltage battery warning message displayed on a new vehicle instrument panel before delivery.
Then, the problem arose for units in the US in November 2023 showing a reduced driving force accompanied by a warning message.

The manufacturer has carried out an initial investigation focused on potential faults in high-voltage battery management systems, but further analysis found that excessive diagnostic requests from other control units in cars could strain the memory of battery management systems.
Because this excessive burden triggers the resetting of the system. Further investigations were carried out between December 2023 and April 2024 aimed at identifying the causes of this excessive diagnostic request.
While no initial software defects were found in the control unit, testing ensures that excessive diagnostic data could cause a reduced power output or have the potential to completely lose driving power or vehicle shut down suddenly.
Long story short, last May Mercedes-Benz discovered a potential safety risk and began a recall period after reviewing production records.
Mercedes-Benz will begin to notify affected vehicle owners before July 23, 2024 and urge them to take their cars to the dealer network. To deal with this problem, the dealer will upgrade the battery management software system for free.
