The cars have alternator cables that can wear through a power steering line, leading to a fluid leak. A leak 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, which could reduce a driver's visibility and lead to a crash.
GM and Chrysler said no crashes or injuries have been reported in connection to the recalls.
Jeep dealers will replace the windshield wiper motor free of charge. The recall is expected to begin this month. Owners can contact Chrysler at 800-853-1403.
GM dealers will secure the steering lines and reroute them if necessary to prevent contact with the alternator cable at no cost to owners. The recall is expected to begin by Nov. 19.
Owners can contact Cadillac at 866-982-2339 and Buick at 866-608-8080 or either online at www.gmownercenter.com.
