Known issues on the 2021 430i. Six recalls sit on the federal record for this year. One concerns a seat belt retractor that may not work as intended in a crash, leaving an occupant less restrained than the belt is meant to keep them. Another covers a head-thorax air bag that can fail to deploy properly in a side impact. A third involves an engine starter that may overheat and catch fire as an internal component wears. Restraint diagnostics, air bag circuit testing and the starting-system wiring and procedures in this manual bear directly on all three.
