BMW recalls more than 100,000 vehicles due to engine starter fault

BMW is recalling 105,588 crossovers in the U.S. due to a software fault in the engine starter that could cause mechanical damage and prevent the engine from starting.

If drivers repeatedly attempt to start the engine for extended periods, it may cause the motor to overheat from an electrical overload. An overheated starter motor could ignite nearby flammable material in the engine compartment, increasing the risk of a fire, according to the NHTSA filing.

The recall covers the 2019-20 BMW X5; the 2019-20 X7 xDrive40i; the 2020-21 7 Series Sedan; and the 2020 X6, 8 Series Convertible, 8 Series Coupe, 8 Series Gran Coupe and 3 Series sedan.

BMW first became aware of the issue in March 2023 after receiving reports of engines not starting and thermal damage in the engine compartment, according to the NHTSA filing. By August 2023, potential fault patterns were identified. Further reviews this year linked specific engine starter configurations that could be associated with the reported cases of the fault. On July 25, BMW decided to initiate a voluntary safety recall.

BMW is aware of about 12 customer complaints and related field incidents but has not received any reports of accidents or injuries linked to this issue.

BMW is responsible for the software, and no specific hardware is involved in the recall. Potentially affected vehicles will receive a software update to prevent the engine starter from being electrically overloaded.

Dealers will be notified this month, with owner notifications planned for Sept. 23.
