BMW expands recall over fire risk – 145,000 more cars affected

Following an earlier recall of nearly 200,000 vehicles, including the Toyota Supra, BMW has now expanded its global fire-risk recall, adding six more models and a further 145,000 cars in the United States. As first reported,  the issue stems from a faulty starter motor that may corrode and overheat, potentially leading to a fire risk.

Recall affected BMW models

The expanded recall now includes:

• BMW 340i (2019-2022)
• BMW 840i (2019-2022)
• BMW 740i (2019-2022)
• BMW X5 (2019-2022)
• BMW X6 (2019-2022)
• BMW X7 (2019-2022)

All affected vehicles feature the BMW B48 2.0L Turbo-petrol engine. In North America, the engine starter relay may corrode, potentially overheating and causing a short circuit, which increases the risk of fire.

Details from the investigation

According to a report by the US Department of Transportation (DOT), the starter motor at the centre of the recall was supplied by DENSO of Europe and carries the part number 8671505. The report confirms that three vehicle fires were reported in March 2025, prompting the initial investigation, while a further three “thermal events” occurred during testing in April and May.

No injuries have been reported in connection with the issue.

The US DOT also confirmed that affected owners will be contacted by dealers directly. A full VIN search tool for North American customers is expected to go live on November 17, 2025, to help owners identify if their vehicle is part of the recall.

Impact in Australia

While a local recall notice has not yet been issued, BMW Australia confirmed that the Australian market is expected to be impacted.

The spokesperson said, “We are aware of the global recall and can confirm that the Australian market is impacted. We are in close contact with our head office to determine the specific implications for our market.” 

Many BMW and Toyota models sold locally use versions of the B48 and B58 turbo-petrol engines, which share components with those affected in North America.

What should owners do?

Owners of potentially affected BMW and Toyota vehicles are advised to monitor official recall channels for updates and avoid parking in enclosed spaces until the repair program begins.

The recall builds on a smaller campaign from April 2025, when BMW Australia recalled 273 vehicles — including 520i and X3 models — due to a similar starter generator fault linked to the same engine family.
