A software malfunction that could lead to a loss of power and an increased risk of a crash was the cause of the BMW recall.
The recall applies to certain iX SUVs and i4 and i7 sedans that were produced between October 14th, 2021, and October 28th, 2022. The control unit is related to the software issue. It was said by BMW.
The high voltage battery electronic control unit software may, during certain vehicle operating conditions, cause an interruption of electrical power. Specifically, a misdiagnosis can sporadically occur within the battery management electronics, which could cause the electronic control unit to reset. If a reset occurs, this could cause an interruption of electrical power.
BMW discovered the problem through its own internal quality control process and is not reporting any accidents as a result of the recall.
While waiting for a software update, BMW owners can keep driving their vehicles. The update will be provided by dealerships free of charge, and letters to affected owners will go out next month to recommend they get their vehicles fixed.
This is the second time in less than a year that BMW's new lineup of electric vehicles has been recalled. The risk of battery fires led to the recall of a small number of i4 and iX SUVs.
EV sales have increased so have recall notices. The Toyota bZ4X was recalled after it was discovered that loose hub bolts could cause the wheels to detach while driving. Various software bugs and other minor issues have led to the recall of other EV's.
