On certain 2018 MY Sonata (LF) equipped with the 2.4L or 2.0L Turbo engine, the starter M-Terminal nut may become relaxed and loosened. If this condition exists, the vehicle may experience a no crank condition in colder ambient temperatures. In most cases the starter will function normally at room temperature. This bulletin provides the service procedure to properly tighten the starter M-Terminal nut.
