The U.S. automakers issued the separate recalls on Thursday. GM's recall involves certain 2010 and 2011 model year Cadillac DTS and Buick Lucerne sedans with V8 engines.
An alternator cable could wear through a power steering line, leading to a fluid leak that could cause a loss of power steering and lead to a crash.
Chrysler's recall involves certain 2008 model year Jeep Liberty SUVs. Water could get into the windshield wiper motor and stop the wipers. That could reduce a driver's visibility and lead to a crash.
