Check engine light (cel) is on with p0300 and p0302 codes, exhaust escaping #2 piston head- causing rough idling, cel flashes, and several stalls while in motion. Found out this is "common" on pentastar engines, and parts are not readily available from chrysler to make repairs, and dealers let people drive the car instead of providing alternative transportation. They should have to repair and replace these heads…

My issue with the jeep is that i believe it has an design and engineering flaw. This vehicle has an automatic transmission.
