Glad to hear it is trouble free now. Looks like your gonna be home free from here on out.
I wonder how many jeeps have had the problem so far? Just on this forum, it seems like a lot. Just think of how many owners are not on this forum and have had it. Would like to see a thread with a poll. Of course, a ton of jeep owners have yet to have 5K miles on their cars. I'm at 500 right now...and going to get my oil changed here next week. I might just go to the dealer and ask him to change out my heads as soon as they get them in..and maybe have a clause in there to pay me back in full if there is a TSB, or recall. What do you think a replacement head would cost installed?
First oil change at 500? I had that just getting home from san antonio. Then drove 2000 miles to washington on before first oil change. I would wait to see if you hear a ticking first. Otherwise you wouldnt be able to prove yours had it and I doubt they woyld just give you money back if you had no proof. They have to run tests and stuff and talk to STAR before a head replacement is done. Dont go all hypocondriac on us now. LOL
just dropped my 2012 off at the dealership :-( infected with the tick. build date was december 2011. now ill see how good my dealership is. i hope they don't act like nothing is wrong, or try to blame the problem on my 285/70r17 tires
i have a 2012 built 2-12 with a low ticking but im at 10,200mi now without an increase in the ticking...as a auto tech myself i would say its normal engine noise if it doesnt get any louder.
Well after 6+ months in the buy back/ lemon law process. The Heep is gone. A total bummer. Probably wont be getting back into a wrangler anytime soon. Unless they surprise us with a diesel option in a few years.
I have a 2012 with 2900 miles and just had the first oil change. Cant really hear anything yet, this motor is not the quietest I have heard to begin with.
Just got the JK back with 16,114 on the ticker. New cylinder head installed on Friday 7/20. Low RPM power is back and ovbiously the ticking/roughness is gone. We'll see if this affects my 18.47 mpg any.
New issues though: The damn air conditioning stopped working. Ugh.
The last time I got mine back the AC wasnt working. Since I picked it up at closing on a Friday I thought I would be screwed but then I checked the connectors. It want hooked up when they put it back together. Check that first
just got my jeep back, they said they didn't hear any noises that were abnormal to the 3.6, and that there was no power loss. they had it for a few days and took it for a test drive. driving it home i couldn't help but have the feeling like i was going out with a girl after i knew she cheated on me...ugh
built in december 2011, a little over 5k miles on it. i feel like im hearing the same ticking noise as the ones on the videos that have been posted before. it could just be like a self fulfilling prophecy though, where im so over worried that my jeep has the issue, i keep "hearing" it and want to get it fixed. idk, heres a video of my engine, not the best quality but i think the sound is best heard around 20 seconds and beyond.
for the JK owners that have had the tick, what do you guys think? i could just be that crazy over protective father...
Quick update. My dealer said a new head will arrive in 2 weeks. It did. Was a little worried about this whole back order thing. My only hold up now is that they are short-staffed due to vacations so my vehicle will go in for the head replacement maybe next week.
From what I've heard, you'll surely know when the ticking is there. Also, check your gas mileage over a tank. If you notice your not getting fairly close to the estimated MPG, something is up. Right now I'm sitting at 20.5 MPG average, but only have 1200 miles on it. Already had an oil change at 700 miles. I hear no ticking noise at all after warm up. We'll see how long it lasts... Hope I got a good one...but nobody really knows. I feel bad for the guy that has 100,001 mile and the head fails.
Its the fuel injectors, they seem to be noisier in the newer cars. New ford explorer V6 (non-Direct injection) sounds like a diesel with the hood open.
Probably not going to be anything significant. Maybe half a mile per gallon but it changes with every tank because I'm towering my boat on a regular basis.
