Known issues on the 2012 Grand Cherokee. Four recalls are on federal record for this model year: a connecting-rod failure that can lead to engine seizure and a crash, vanity-lamp wiring that can short and cause a vehicle fire, an electrical-system fault that can stall the vehicle (crash risk), and an alternator failure that can make the vehicle stall without warning. Owners have filed 2,318 complaints and Jeep has issued 121 technical service bulletins for the year. This manual carries the factory diagnostic and repair procedures behind each of those systems.

From a routine service interval to a control-module reflash or a hard-to-trace wiring fault, it keeps you on the OEM procedure and the correct specification for your specific 2012 Grand Cherokee.
