Engine has ticking sound from the left side of the engine and continues to. Chrysler and Jeep complain this ticking is "normal valve noise". but, I have heard other engines of the same year and they do not have this sound. It appears to affect quite a few people from research as well. Engine also feels like it stutters when reversing.

Engine developed a ticking sound on driver's side engine bay. Sounds like engine is missing or tapping on driver's side. Loss of power/stalls more common now. Took vehicle to Chrysler and they say that my engine is just "loud" compared to all other 2012's and that it's normal. They told me to just drive it until it fails and then bring it back in because Chrysler corporate will not allow a dealership to work on the engine and fix it until a failure occurs. So, now I am stuck with a 3 month old 2012 Wrangler waiting for it to breakdown on the side of the road before the dealership will fix the known issue. Mechanic says "that doesn't sound right" when I took it in. Mind you I took the Wrangler into two dealerships at this point for multiple opinions. Both agree the Jeep will fail and to just "wait" until it does because they are told by Chrysler to not work on faulty Wrangler with the new pentastar engine until the engine completely fails. Real proactive on that decision Chrysler. I'm not looking forward to the day power is lost when I'm on the highway or crossing train tracks. Thanks a lot for putting my life at risk over a known issue yet not acting on the known fix. Both dealerships claim they know heads are being replaced when this symptom is found on 2012 Wrangler. That's all I'm looking for, fix what was not built correctly in the first place like others.
