The 3.6L Pentastar engine for this year has been shown to be highly problematic. We have had the #2 and now the #1 cylinder heads fail, causing misfires, poor engine performance and complete failure. We’ve also had multiple injectors fail, #2 (twice), 4 & 5. The engine failure is a safety issue and has been proven as such.

- Check engine light - code: P0302 (Misfire Cylinder) - This is a converted wheelchair mini-van and I am in a wheelchair. Break-down on freeway would leave me stranded. - Apparently this #2 cylinder problem was part of a recall for 2011-13 Pentar 3.6L engines and from what I have read online the problem still persist and in 01/2022 a class action lawsuit has been filed against FCA for this exact problem (See attached). - I have taken the van into both the dealer and independent service center - Heads need replacing due to known bad cylinder head problem with these engines. - Check engine light came on in 03/2022 and I paid to have plugs and head gasket replaced only for the P0302 light to come immediately back on. Took back in and 2nd experienced tech confirmed head problem and instructed me to go to dealer; dealer confirmed head problem but said no recall available as of yet. Dealer quoted repair cost to heads of $5,145!!!

Light came on (not flashing) took to Auto Zone for a diagnostic which the ASE Certified Technician said the error code was PO301 cylinder 1 misfire was detected and it was the #1 spark plug and it needed new one. However the spark plugs are not scheduled for maintenance until 100 k miles and my van is just over 60 k and I had my dealership do the 60k maintenance in March but didn’t include the spark plugs. We had a mechanic from out of town look at it per our dealership as we were out of town. He reset the code on 6-1-2021and it came back on after 7 days for two weeks it went off and came back on again on 6-11 and went off on the 14th. Today is the 15th of June, 2021.

(automatic) highway, local roads, uphill or straightaway. Car has difficulty accelerating past start up speed. When starting from a red light into 2nd gear the car will quickly slow then go from 1st gear to 3rd. Sputtering, hesitation. After I've already reached speed limit. This has caused many issues with close 'rear ending ' issues. People rear ending me or my rear ending them because of the quick/hard shifting. Car has been seen 2x since feb. 2020 going on 3x. Same complaints. Exhaust has thick white smoke, smells slightly of gas. Engine check light diagnostic: 2nd cylinder misfire. 1st service fix focused on thermostat and repaired it. 2nd service diagnostic showed cylinder 2misfire again. Repairs focused on changing spark plugs and fuel injection decarbonizer. Last seen 8/2020 today is nov 1st. I have another check engine light with same issues. 2nd cylinder misfire. I feel as many unsafe issues this car has I'm afraid to drive it. So it is sitting in my drive way. I've read it could be the transmission or it could be a coil. I've heard the repairs could cost upward of $2500 and that this is a common issue with this type of engine.
