2014 V6 - Cylinder Head Failure

Hello everyone,

I was on my way to work today on the highway. I had the cruise control set at ~70mph and all the sudden my engine started hesitating and the check engine light started flashing. I know that a flashing CEL is bad so I immediately pulled off to the shoulder. When I came to a stop, the CEL turned off but the Jeep was shuddering and idling very rough. I turned the engine off and tried to figure out what to do next.

I was figuring flashing CEL = Jeep was going to have to be towed. Traffic was whizzing by me at 70+ mph and I was very close to my exit, so I decided to attempt to get off the highway to a safer location. When I started the Jeep back up, the idle was back to normal and there was no shuddering. The CEL came on but, this time, it was solid instead of flashing. I started driving again and the Jeep seemed to be running normal except for a very slight hesitation, but nothing compared to the original hesitation.

I ended up making it all the way to work with no issues. I called the Jeep dealer that's local to my office and asked if I could bring it in but they told me they were too busy and couldn't take any appointments until next week. So, after work, I carefully drove the Jeep back toward home and took it my local dealer since they don't require appointments for service. Again, the Jeep seemed to be running normal - just a very slight hesitation in comparison to earlier.

The dealer diagnosed the CEL and told me I need a new cylinder head. They ordered the part and said it will hopefully be in next week. They released the Jeep back to me and said it's OK to drive until the part comes in. They just said I might notice some hesitation though.

I did some searching and saw quite a few posts about this issue for 2011-2013 WK2s but I didn't really see anything for 2014+ WK2s. I was just curious if anyone else has experienced this issue with their 2014+ WK2? I'm a little surprised that a vehicle with only ~10,500 miles needs a new cylinder head. Also, is it really OK to drive the Jeep until the part comes in?

Re: 2014 V6 - Cylinder Head Failure

I wonder you had a misfire code and the tech simply jumped to the conclusion that it was the head because that was a common symptom with the earlier head failures. Lots of other things can cause a misfire ( bad coil, bad plug, loose wire, sticky injector, etc.) Your rough running condition improved after a restart so I'm guessing you probably had something that caused a temporary misfire condition. If you were really having the head problem, you likely would have been hearing a valve tick at idle for a while before you got the check engine light. You definitely would have noticed the tick.

Re: 2014 V6 - Cylinder Head Failure

What code are you getting ? Was the tank getting low ? Sure sounds like a termorarily clogged injector or something similar.

A misfire (P030x) will set anytime one (or more) cyls slows the engine which is why the exact code (one cyl vs many and which) is important.

ps with a $10 dongle (OBD-II) and a $5 app (Torque Pro) any Android device with BlueTooth can read codes and a lot more (plug). I check mine about monthly and e-mail the results to myself.

Re: 2014 V6 - Cylinder Head Failure

I'm with airgas, I too believe the left cylinder head issue was resolved with the 2013s. I have a 2013 with an October 2012 build date and am supposed to be OK. get yourself a code reader with the ability to clear the codes as well, I got one from harbor freight for $80 bucks on sale, used it once to clear a code for the emissions system, which I believe was caused by my using the pressure washer under the hood, 3000 mi. later, CEL never came back on, no trip to the dealer, so it paid for itself already!

Re: 2014 V6 - Cylinder Head Failure

I agree with what others have said. This does not sound like the cylinder head problem to me. Did the dealer do a leak down test? That would tell them for sure.

Re: 2014 V6 - Cylinder Head Failure

Hello everyone,

Sorry it took me so long to update this thread. Thank you all for your input. I'm not very mechanically savvy but I'm thinking I should invest in a code reader for going forward. When I initially brought the Jeep to the dealer on 12/5, they got code P0300. According to the paperwork, they found a misfire on cylinder #2. They performed the leak down test and found 60% leakage which is how they determined that the cylinder head needed to be replaced. I have the Jeep back now after having the left cylinder head replaced and so far, so good. It seems to be running a lot better than before but that could be because I've been driving a Hyundai Santa Fe loaner for the past two days. I was so happy to get back behind the wheel of the Jeep! I'll be sure to keep you posted if any other issues come up from this.

Re: 2014 V6 - Cylinder Head Failure

Bumping this thread to ask a question. If either of you guys are still around, did you have an engine tick before the head was replaced? My '14 V6 has a very loud tick that seems to be coming from the passenger side head area. I'll be taking it in soon to be looked at under warranty. Hopefully it's just a bad injector or something, but it makes the Jeep sound like a hooptie.

Re: 2014 V6 - Cylinder Head Failure

My engine was quiet, never any indication that it was a cylinder head issue. Drove fine just kept seeing the check engine light. Hopefully your problem is not too serious.

My engine was also quiet and I didn't notice any ticking before the cylinder head was replaced.
