Check Engine Light On problems of the 2012 Jeep Grand Cherokee
Four problems linked to check engine light on have been reported for the 2012 Jeep Grand Cherokee.
Check Engine Light On problem #1
The car involved was a 2012 Jeep Grand Cherokee. The VIN of this vehicle was 1C4RJEBG3C_. I bought the vehicle from a dealer with 14,500 miles on it. Still under the 3 year, 36000 mile warranty. Started the engine only to have the check engine light illuminate. Drove byautozone and red the code, p0304, misfire on cylinder 4. Brought the vehicle to the dealer where purchased and he sent it to the Jeep dealer for service. I was given a loner car from the dealer I purchased it from. I received the vehicle back on wed. July 31st from my purchasing dealer and was told the computer was flashed and re-programmed. Thursday morning, the day aftr the repair the check engine light illuminated again. Called the dealer I purchased the vehicle from and will be dropping off Friday morning. I know of the inherent issues with the 3. 6 l pentstar engine cyllinder heads and want both heads replaced. It was Friday, July 26, 2013 when this check engine light on issue occurred.
Check Engine Light On problem #2
The car involved is a 2012 Jeep Grand Cherokee. 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 that have now been redesigned in more current builds. Letting people drive cars that can stall in motion is dangerous. Not having parts readily available when they are having 300 to 400 of these failures a week is ridiculous. The attached link shows that Chrysler had this part shortage since last summer, and is not meeting the demand for replacements even now. This check engine light on problem happened on 05/14/2013..

We took it to autozone and they plugged into it and they displayed a misfire on 2. This is the 2nd time it happened. The first time Chrysler changed the head. Now its in the shop for the same issue.
