BMW has issued recalls for about one million vehicles in North America over two separate problems it said raised the risk of fire.
One recall affects BMW 3 series models from 2006 to 2011, which it says contain wiring that could cause the luxury sedans to overheat.
The other recall involves a faulty valve heater installed in some 2007-2011 models.
BMW said dealers will replace the faulty equipment for free.
The firm expects to notify owners in December.
Each problem potentially affects about 700,000 vehicles, according to the notification on the National Highway Traffic Safety Administration site.
