Some Jeep Patriot owners report experiencing starting issues characterized by no crank and illuminated warning lights, which may be linked to a malfunctioning Wireless Control Module (WCM). Common causes include weak batteries that can lead to clicking noises and prevent cranking, even if the battery appears to be in good condition. Additionally, loose or corroded battery posts and terminals, as well as poor starter electrical connections, are known to contribute to these starting problems. Ignition issues, such as a lack of spark or misfire-related codes like P0300, can also prevent the engine from starting. Furthermore, engine mechanical concerns, such as timing belt failure, can hinder proper engine function and lead to starting difficulties. Some owners have found that resetting the WCM by disconnecting the battery for a short period may help resolve these issues. It is important for owners to systematically address these potential causes and consult a professional mechanic if the problem persists.
