So this is the info I wanted to know...

"Betts said the problem has been found in about half of 1 percent, or about 7,500 of the approximately 1.5 million Pentastar engines that were built over the past two years"

This makes me a feel a little better that I can beat the odds of having problems.

Matt I hope all owners are treated that way.

Roy he says they have "found" the problem in .5%. I'm skeptical that it's limited to 7500 heads, I hope I'm wrong.

The reprogram or new lifter process must have cost millions in worthless warranty work for Chrysler on top of head replacement costs.

I'd rather know what the percent is of 2012 Wranglers with/without the issue, even if the numbers just come from this forum. Maybe someone with a 2012 who has this issue should start a poll... or some industrious soul could count the number of people in this thread reporting the issue and compare it to the number of people in the Class of 2012 thread or the two original 2012 order threads.

If you have a 2012 you obviously have a warranty, so the only worries you have are inconvenience, lost time, and possibly stress. I had a head on my 2011 3.8 replaced for ticking, so I know it's discouraging to have a major engine repair at low mileage. I say 2012 owners can feel good knowing they will have their problem fixed one way or another, yet those considering a 2012 or even a 2013 should buy with eyes wide open. I'd love to have the 3.6, but I want to see what happens first. I'm more inclined to hold out for a diesel or the model redesign since I already have the new interior.

I m really suprised they would try to spread the problem out to all pentastars. Other then a few Grand cherokees and All these Wranglers I have not read about this issue in other cars such as challengers or avengers.

I am a meber of about 5 other forums which I will not name because the rules say not too but only on this Forum do I find so many. I would think they would say its mostly Wranglers since there are 12 complaints filed with the governemnt. Where are the other model years or Makes of Pentastars complaints to the feds? I would have expected the complete opposite more like put it all on Wranglers since your going to upset people who probably are already upset because the word of mouth is getting out. Also as noted the heads are supposedly different on the Wrangler then others where as I never heard of the heads being different for the Grand Cherokee or challenger or Journey.

And again on all those other forums there is no where close to anything like this thread. Of course just as someone else stated back in the 90s the transmission failures which were suppose to be isolated and sooner or later all failed.

I m just getting rid of mine. Anyone wana buy it? I didnt think so. AND I also worry about a recall or when this gets out even more or hits the mainstream Media whats that going to do to resale value?? I mean is the 12 Wrangler going to have a reputation as the 2002 Ford Explorer still to this day has as the worst model year ever built and to stay away from them (they had defective rear axles)

I've been following this thread since I bought my 2012 jeep 2 months ago, at first I felt sick knowing I just purchased my first new car and there are people having major problems with them. I drove around paranoid for about a month and a half but have now realized that being paranoid every time I drive is probably worse then having to take my jeep in and get it fixed, so I just turn up my music and enjoy driving.

If I hear this tick, I'll take my jeep in, get a loaner, and tell them I'll pick it up when they show me what's been done and I am happy with it. And if the new heads aren't a permanent fix, I'll cross that path when I get to it, but for now, I'm enjoying my jeep carefree, a vehicle isn't worth losing sleep over in my opinion.

Thanks for your service! And whatever you do, get it fixed there. Like politicians in Illinois, the dealers here are a bunch of liars and crooks. I should have you take mine with you and get it fixed there!

I am in NC and my dealer is a jerk and so is the dealer in the town 20 miles west and the one 10 miles South. So I just clarify if he found a cool dealer, it has nothing to do with being in NC.

From the article.

He said the malfunctions were the result of "an interaction of a lot of rare things that ultimately come together to affect a small percentage of the population." Those could include different fuel mixes and the way the vehicle is driven, he said, though he did not explain further.

Lee said there are limits to the percentage of Pentastars that will experience the malfunction because of the variables involved.


"You have to have this fuel characteristic, you have to have this drive cycle -- and all of these things have to line up in order to have this situation occur," Lee said. "That's why" the number of potentially affected engines "is so small. If it were a design defect, or if it affected [a basic component] like the integrated exhaust, we'd have issues on everything, which we don't."
So did they just inadvertently say that ANY 3.6 will start ticking if you drive it a certain way and with a certain fuel mixture in a certain pattern over time? Obviously they figured out how to reproduce the problem and cause the issue to manifest itself. So I'm wondering what all the people with this problem use for fuel (ethanol content, octane levels), how they drive (hard, slow, highway, city), and how often they drive.

Isn't that the measure of a design defect: when it can happen to anyone? How does the fact that it's rare make it not a design defect?

That might be another interesting poll. What Octane rating is being used by those with the problems. I'd also be curious as whether or not anyone had issues with a 3.6 that was mainly driving at high altitudes, i.e. Denver, or is this an issue mostly for people at sea level.

it s a crock is what it is.

Everytime they dont wanna admit its their fault they say "It's bad gas"

I for one get gas at many different places hardly ever the same place and use Reg unleaded.

I bought mine because I planned to drive from East Coast to West and back again thats roughly 5,000 miles so what happens when I get the code in Nebraska.... I mean I bought a brand new car just for this now I might as well set out in a 76 PAcer with my fingers crossed and I would feel just as secure as taking my brand new car.

OUTRAGEOUS!
