Interesting. We bought a used 2010 Cherokee Laredo with the 6 cylinder like yours and the engine light is giving us fits too. Started searching the web and found conflicting remedies, as if the car had been produced by four different manufacturers. Dealers seem to be waffling on what to do. One even blamed the EZPass windshield stickers. The electronics for this year are beginning to look defective. Maybe a recall is warranted. Hope yours was finally repaired. Others on this site seem to report fewer problems than forums on other sites.Report it
