Daimler Truck has launched a global recall covering more than 131,000 commercial vehicles after identifying a defect in the electrical energy supply system that could increase the risk of overheating and fire.
The recall includes diesel-powered Actros and Arocs trucks as well as first-generation battery-electric eActros 300 and eActros 400 models equipped with AGM batteries. The company’s latest eActros 600 long-haul electric truck is not affected.
First-Generation eActros Models Included in Recall
According to Germany’s Federal Motor Transport Authority (KBA), the issue stems from an improperly installed ACE chip within the battery system. Corrosion may develop on the chip’s electrical contacts, potentially generating excessive heat during vehicle operation and, in extreme cases, leading to a fire.
In Germany, the recall covers 27,084 vehicles manufactured between March 2021 and October 2025.
Affected battery-electric models include the first-generation eActros 300 and eActros 400, which are primarily used for regional heavy-duty distribution. Depending on the configuration, these trucks are equipped with three or four battery packs providing capacities of more than 300 kilowatt-hours.
Daimler Truck confirmed that the second-generation eActros 400, which entered series production in December 2025, and the flagship eActros 600, which began production in November 2024, are not included in the recall campaign.

Repair Involves Disconnecting Defective Component
As an interim corrective measure, authorized service centers will disconnect the affected ACE chip on recalled vehicles.
According to the company, some of the components were manufactured with insufficient resin sealing, allowing corrosion to develop on the electrical contacts over time.
Daimler Truck said it is working closely with the KBA to manage the recall and monitor the effectiveness of the corrective action.
“Daimler Truck AG is aware of only isolated incidents related to this issue, and no personal injuries have been reported.”
The automaker said the recall is part of its ongoing quality assurance process and urged affected vehicle owners to arrange service appointments through authorized workshops.
