The first recall covers nearly 542,000 Dodge Journeys and Fiat Freemonts from 2012 to 2015. Moisture can build up in the anti-lock brake control module, disabling the system and the electronic stability control.
Fiat Chrysler found the problem by investigating warranty claims. Dealers will apply a sealant and replace electrical parts if needed.
The company also is recalling 352,000 Jeep Grand Cherokees and Libertys from 2003 and 2004 because the air bags can inflate for no reason. Seven people have been hurt. Dealers will replace the occupant restraint control computer or the side impact sensors.
