- Mercedes-Benz is recalling 632 EQBs in Canada, and another 7,362 in the U.S.
- There is an issue with the high-voltage battery that could overheat, causing a fire risk
- Mercedes-Benz is asking owners to avoid fully charging the SUV
Mercedes-Benz is recalling certain EQB Class EVs due to a potential fire risk stemming from an issue in its high-voltage battery. The company says 632 vehicles in Canada are affected by this recall, along with another 7,362 in the U.S. While Transport Canada (TC) lists the EQB Class as a whole, the National Highway Traffic Safety Administration (NHTSA) lists the affected vehicles as the EQB 250, 300, and 350.
While TC lists the 2022 and 2023 model years of that vehicle as being covered by the recall, the NHTSA includes the 2024 models, as well. Interestingly, in the recall report provided to the NHTSA, Mercedes also includes the 2025 model year in the description, and indicates the issue doesn’t affect anything built after January 24, 2024, due to “optimizations in the production process of the supplier.”
To confirm if your vehicle is affected by this recall, you can also check online at Transport Canada, using your VIN, to see if your vehicle is affected by this, or any other past recall. Transport Canada’s number for the Mercedes-Benz recall is 2025-041, while the manufacturer’s recall number is 5496507.
Apparently, the defect in affected vehicles include battery cells from a supplier in its “early-stage production period.” The report notes the combination of prototypical production and vehicle use conditions (such as mechanical damage) could cause an internal short-circuit of a battery cell in the high-voltage battery. This could cause the battery to overheat, which poses the risk of a fire.
If this happens while the vehicle is being driven, the driver will see a battery-warning-malfunction message in the digital dash. However, note that if the car is parked and turned off, there will be no indication or warning of this issue.
Currently, the remedy for this recall is still being developed. Once it becomes available, owners will be notified by mail and advised to take their vehicle to a Mercedes-Benz dealership to have the battery management system software updated, free of charge. Until then, Mercedes is advising owners to refrain from fully charging their vehicle to 100%, and asks them to instead set the maximum charge to 80%.
According to the report, Mercedes received reports of “fire incidents” from the Chinese market beginning in 2023. While no root cause was found, including external conditions related to the local market, Mercedes could not guarantee it wouldn’t happen in other areas, which led to this safety recall campaign.
