The 2023 BMW X4 has two recalls, both rated at the same severity level, with the more consequential being a starter assembly defect that can cause a fire.
The starter motor can overheat and ignite, raising the risk of injury to occupants or bystanders. On the drivetrain side, transmission oil can leak into the transmission control unit, causing the gears to seize and cutting drive power without warning, which raises the risk of a crash.
