cheap4tw I had the cam phasers done on my 2012 at around 45000km on the odometer. Not sure if I'm nuts or not but after they did them my mileage seemed to become more consistent.

DynoMax Exhaust So.. this just happened to my 2013 JKU with 3700 miles, getting replaced right now. Weird thing no code was thrown that I was able to see by doing the key trick. ECO didn't work and ran rough for a short time.

nitroz680 Hmm...yea Jceo noticed a bit different ride quality I think. I'm sure the dealer will be able to diagnose but make sure you ask them if they inspected for wear on the cam lobes.

Hope its not in the shop too long :/

A little at idle. You feel the cylinder misfire (I think). I'm sure the dealer will take care of it, but it's pretty annoying. Glad I found the thread, I will have to follow your progress.

jceo Glad to hear you have your Jeep back! You're right, it is probably an electronic issue that will have to manifest itself again for proper diagnosis. Enjoy the Jeep bonding this weekend and keep us posted if anything new happens

There seems to be some red herrings but my general feeling is that I just had/have an electronic issue and it will have to manifest itself again before it can be fixed.

I got it back Friday afternoon and drove it all weekend with no trouble, I was in serious Jeep withdrawal. In fact, I have some bonding planned for this weekend, maybe a nice wash, hopefully install a "new-to-me" 430 head unit, and more shirtless, topless Jeepin!

jceo Any updates Nitro?
06-06-2013 02:32 PM
nitroz680 Yea, just got a call from the dealership. They have been in contact with Chrysler, and the dingdongs at Chrysler think its a fuel quality issue, they had the nerve to ask me where I was filling up my tank of gas and with what grade...its a friggen Jeep, not a lambo, this thing should run off dog piss!

The dealership told me that there is no mechanical wear indications and the codes are all erroneously tripped. The engine thinks it is misfiring on cold start when they said they verified it isnt. Needless to say, it wont be ready today. I mentioned that i've heard of this issue before and that a colleague (that'd be you Jceo) had to have his cam shafts replaced, and the dealer insisted there was no mechanical wear, this is exclusively an electronic malfunction.

I asked what was going to happen with my rental agreement tomorrow when I reach my 5th day, and before i could finish the sentence he told me to not even worry about it, they'd get me covered, so at least that's encouraging.

You should definitely have leverage. All the dealer has to do is get Jeep Customer Assistance to authorize the additional charges for the extra days.
06-06-2013 02:17 PM
jceo I think you should have some leverage on the rental car. You bought a brand new $30k plus vehicle and are now without it. It is the least they can do.

jceo Nitro, it was there from last Thursday to this past Wednesday so 7 days but that is including the weekend. They had to order the parts. I know how you feel. Any updates on yours? I am curious to see if it is the exact same or a similar issue.
06-06-2013 08:42 AM
nitroz680 Jceo,

what was the total time in the shop? My Jeep has been in the shop since monday and by now its thursday. After all the work performed on your vehicle, it seems discouraging that I'll get mine back today
06-06-2013 08:35 AM
jceo Blastek, Nitro, Everyone: Here is an update on my situation. I have my 2013 back and it seems to be running well although I feel a slight rough idle occasionally. The dealer went through quite a bit of diagnosis and opened a Star case with Chrysler. The mechanic is a fellow Jeeper and quite sharp. They replaced both cam phasers, cam gear and both camshafts on the left head. They found flat spots on the camshafts which they have never seen before. Has anyone heard of this before? I am keeping my fingers crossed. Only around 2500 miles.
06-05-2013 10:30 AM
live_slow Hope it gets resolved. Subscribed.
06-05-2013 09:08 AM
jceo Nitro, Similar situation here. They determined the cam phasers were bad and are replacing them. I should be picking it up today so I will let you know the outcome. I also have a 2013 JKU Sahara that I got in March. Ours were probably going down the assembly line together and got the same batch of engines. That could explain why we are having the same issues. I know how much it sucks not having your Jeep. I have been having anxiety driving the loaner car hehe.
06-05-2013 07:54 AM
nitroz680 the Jeep has been in the shop for 2 days and the dealership is still on the horn with Chrysler engineers regarding the problem. The service manager said the cam sensors were verified to be working properly. Further compounding the confusion is that the code that caused the check engine light is a stored code, meaning the problem happened once but is no longer happening.

wtf

not necessarily. the misfire code could be caused by something else, like a fault in the injection or ignition system, a stuck valve, or other issue. Most of the people that have had their head replaced ended up with a P30x misfire code on the left cylinder bank, though.

Im in the same probability pool as you with less than 5k and issues, granted mine is not the ticking head. Chrysler engineers are boobs, they just throw random parts at common problems that doesnt result in a fix. Good luck with what they do.

nitroz680 From reading other threads on this forum, it seems like this has happened before.

In general, my ride quality is unaffected, i havent noticed a rougher ride or rough idling. I have noticed that ECO mode is never achieved anymore, not sure what thats about.

Leads me to believe that my issue is all electronic and not mechanical.

Thanks for the update! I hope your issue gets resolved. We've all been very focused on the '13s after all the 2012 head issues. Good luck, sir!
05-30-2013 10:57 PM
Martin10 That sucks guys. Is this a common issue?

Up Hill Bill IF I recall correctly - which is anything but a sure thing - in the early days of the well known Pentastar head issue, cam phaser problems were cited as a possible cause. Dealers tried a flash update for the phasers, cleared the codes, and sent people on their way. When the MIL came on again, they then replaced the drivers side head.


Anybody else remember it that way?
05-30-2013 12:49 PM
Blastek hmm cam phasers were a problem on the very early pentastars. Odd that it's back. Let's hope it wasn't a multiple misfire code.

jceo, please keep your outcome updated. I'm very interested to see if they go for a new head.
05-30-2013 12:43 PM
legitposter Your cam phasers are out of phase? You've been watching too much star trek.
05-30-2013 08:45 AM
nitroz680 unfortunately I didnt get the code number this morning from the guy that ran it, he only confirmed it was the same code as the code that registered last time I had it in there. I believe my cam phasers are either out of phase or have gone bad. Or i could be an idiot and have no idea what im talking about.
