2012 Jeep Wrangler Sport Blown Engine

Well, it finally caught up with me. I just got word from the local dealer, after a week in the shop, that I need a new engine. It began a week ago when the engine lite came on and eventually stalled. I called AAA and it went to the local dealer. Now after a week I get this upsetting news. They had replaced a fuel injector, were able to start it and drove it for 25 miles. They then said it would run OK for a while and then would not idle. They then asked to go deeper into the engine. After a week I was told that the pistons on the passenger side were scored, and the block looked as though it was warped. I have taken the best of care of this Jeep. I took care of all the recalls. Replacing the drivers side head which was a recall item. Power windows wiring recall, I replaced the master cylinder out of pocket. Replaced the Clock Spring which became a recall. Replaced the Thermostat. Passenger airbag recall. The Jeep is 7 yrs old and has 56,500 miles. Today I was told I needed a new engine. Rebuilt out the door $9,038.56! New $10,819.00 On both, a three year unlimited mileage warranty. I called Chrysler-Jeep and so far they are unwilling to assist with any compensation. Any suggestions?

Try and find a take off from one of the Jeep shops that do hemi swaps and such.

Ouch! And unfortunately out of powertrain warranty so they will not compensate. Find some of the big wrencher guys in a local Jeep club to hunt down and install, check local craigslist and offroad shops and pick & pull places for a used engine. You could get it done for a fraction of that, just be out some money for pizza and beer and the engine parts. But it may not give you a 3 year warranty. Or ask the dealer what they will give you for it on a trade and just get a whole new Jeep, assuming at 7 years old its paid off.

I did a Jasper reman engine in a a previous vehicle, Dakota AWD Quadcab, for $4000 OTD. Dealership actually gave me better price than local trusted shop. $9000 seems like a lot.

Dealers always charge excessively high fees for work. Do yourself a favor and have the rig towed to a reputable independent shop for a quote. Bet the out the door price will be several thousand lower. Or just sell the rig as a roller and buy a replacement. You’ll never recover the costs associated with the replacement engine.

Unless you actually trust this dealer, I would take it to a local independent shop you trust and have them look at it. The story seems odd. And the prices they quoted are crazy, not only that is too much money to replace a motor but the difference between new and rebuilt is less than I would expect from a dealer (because I can't imagine a dealer being that good about the price of a new motor, I would expect a bigger difference in price).
I would not only want to know what happened, but why it happened. If they can't tell you that I am not sure I would trust them to replace the motor.

To your story, which "engine light" was on? And why did you keep driving it like that and how far / long?

Thanks to all for your suggestions.


Answering some of your questions. The engine lite came on and the Jeep stalled. I was able to start and drove about 2 miles with very little engine power.


The Jeep is paid for but without an engine a new Jeep as a trade in on a new one was not a viable option. I could not buy a new Jeep for the cost of the new engine and note the Jeep is in excellent condition.


I checked prices with a respected Independent Jeep repair service and prices for used & new engines were about a thousand lower than the dealer estimate. Remember this is California and everything is higher priced from carrots to Jeeps! Getting the Jeep to this independent location also presented additional problems.


I was able to arrange a meeting with the Service Advisor and the Service Manager. The Service Manager had been an Advisor and was helpful with an earlier problem. I was glad he had been promoted. He's ex Marine I'm ex Army and he was great to work with. We were able to come to an agreement on the cost of the new engine, to which I am comfortable.


As many of you know dealerships have their problems, poor customer service, unqualified mechanics, etc., but I feel this dealer will back their agreement.


I guess I'll call this an inconvenience and be glad that I have the resources to make the fix happen. I should have the Jeep back in a week. I'll keep you posted.

FCA should hang their collective heads in shame. A well-maintained vehicle should not need a new engine at 7 years and less than 60,000 miles.

Ask the dealer to shop around for an engine, or ask your local non-affiliated mechanic to do it.

I had my 2014's engine replaced with a new take-off from LKQ in 2017. $3,374 for the engine, $5,012 total with labor (and covered by my insurance, long story...)

2012 Jeep Wrangler Sport Blown Engine

This is frightening. When I was talking to a mechanic friend of mine before buying my ‘17 (after having good luck with several “old” Jeeps) he warned me that “all Fiat/Chrysler vehicles are junk, including Jeeps”.

I didn’t believe him and bought a Jeep anyway.

Then I read a story like this and I have to say it scares me. To think of needing a new motor in a vehicle with 60,000 miles is absolutely incomprehensible. Especially nowadays when Toyota’s and Honda’s regularly hit 250,000 miles. Heck I have a Ford Ranger with 230,000 miles on its 4.0 and other than oil changes the only thing I’ve done is a couple of spark plug replacements, a radiator ($80) and a thermostat housing ($100 for a cast aluminum one).

I hope you figure out what went wrong...

We might never know. I will be sending a complaint letter to Fiat/Chrysler regarding this issue. I'm sure nothing will come of it but at least I will have made a formal complaint.


Thanks for all your comments.

There is no reason to be scared. Engines don't just randomly die or wear out prematurely without reason and Pentastar is no exception to that.

OP's engine has overheated, which is clear from the "warped" comment. He states having had prior head replacement done and it is very possible that the mechanic of that time did not do the job well and subsequently OP's engine was eating up coolant, which was not noticed until the engine overheated.

Know and understand the Achilles Heels of this engine and treat it accordingly including replacing items of the cooling system ahead of their failiure.

Keep much more rigorously checking your fluids than you otherwise would have, use the proper viscosity oil that this engine was designed for (do your research) and your engine shall last just as long as the competition.

Very sad. I wish you had the lifetime warranty. Been interesting to see if they would have replaced the engine. I have lifetime on my 2018 JKS, but from reading different post, it seems somethings they honor them, sometimes they find an excuse not too.

Sounds all a bit suspect to me. I mean they went from a faulty injector diagnosis to an unsalvageable engine that "looked like it might be warped"? Seems like it might have been a simple problem that turned complicated because they took the engine apart. I bet they just thought it would be easier to replace after tearing it apart. I've been there.

Granted, there are plenty of Pentastars running troublefree with high mileage. This situation, though - a known issue of bad heads likely contributed to, if not directly resulted in, a dead engine just out of Powertrain warranty.

And the vast majority of vehicle owners do not do their own maintenance, let alone repairs. Dealerships service departments are not going to give you a list of "Achilles Heels" so you can monitor them at home. If the OP chose to maintain/service the vehicle at the dealership, and they were the ones who replaced the head, I would definitely be pushing hard to show the head replacement (or whatever else they might have done) resulted in premature failure. If they can look at you with a straight face and say: "Sorry, you're out of warranty and out of luck," then no one should support FCA or this particular dealer any longer.

And you can add to the list of crap engineering and manufacturing, along with corporate greenlighting, that leads to potential premature failure: the oil filter adapter/oil cooler assembly; frequently leaking raidiators; casting sand issues; the HOAT/OAT coolant changeover and subsequent destruction of entire cooling systems when the two are mixed....

I agree with you, but only to a certain extent.

Because none of these problems pose any issue for someone who is skilled to work on the engine. As a matter of fact, these days and in it's class, Pentastar is one of the simples and easiest engines to work on and it's Achilles Heels are relatively easy to deal with.

This is in stark contrast to many other engines in the market today, that arguably do have their Achilles Heels as well, except that in many cases those require way more serious, invasive and time intensive corrective action that in the end still will only resolve the issue temporarily.

But hey, this is the world we live in. You have to chose your demons. As someone who exclusively does ALL the repairs on our vehicles, which really means ALL the repairs, no matter how big or invasive, I choose (and have chosen) Pentastar over any other engine any day.

However I like to empahsize, that once those simple issues are properly monitored and attended, there is no reason for this engine not to last for a very long time.

To be even more clear to me this means:

- I use 5W30 oil.

- preemptively and prematurely change your coolant and corresponding components (radiator cap, thermostat and related thermostat housing/channel plastic component AND the whole oil cooler assembly)

- frequently check your hoses and radiator for leaks and change or update things as needed.

- check coolant level in you recovery bottle very, very often. In addition, check the level when the engine is cold and verify that the level rises when the engine is hot. Should the level NOT rise between cold engine and hot engine condition (so if the coolant just sits there), then you know you have a cooling system problem already pending.


Most importantly, stop paying attention to anyone who tells you that THIS cooling system is sealed - it is NOT!
This is a recovery tank type system by design and as such coolant level needs to be checked and coolant added periodically!

I think Wrangleur makes several good points. When the left head was replaced, maybe it was installed incorrectly because I had noticed Jeep was going thru coolant on a regular basis. I especially paid more attention to coolant levels after the spring clamp at the radiator came off and I had to have the radiator flushed and fresh coolant added. I also got rid of the spring clamp and went with a screw down clamp. Regarding oil. I had been using Pennzoil Gold Synthetic Blend Oil 5W20. I never noticed a drop in oil level. The Pentastar engine does run extremely hot, yet I never noticed the temperature gauge indicating an overheat during this last episode. Thanks for your comments Wrangleur.

How it could be possible - coolant is not expanding?

When the coolant level in the recovery bottle does not rise and fall with the transition from cold engine to hot engine and vice versa, then that indicates a leak in the cooling system somewhere. This rise and fall can only occur with a properly working radiator cap in a cooling system that is pressure tight. In cases when the coolant just sits in the recovery bottle, a leak in the cooling system is present and coolant is simply going to be used up from the radiator. The radiator might be e.g. only 80% full. Thereby this is a very dangerous scenario, with a serious cooling system problem present and worse, OVERHEATING PENDING, that is MASKED by the seemingly proper coolant level in the recovery bottle.

In other words radiator cap needs to be removed periodically and coolant level inspected in the radiator (when cold off course)?

Yes, that can be done to double check (when cold of course), but that would be only required if the above mentioned 'rise and drop' condition can not be observed.

If the the above mentioned 'rise and drop' condition can be positively observed, then it means that the radiator must be full and the system is operating as it should.

There are around 1 million JK's running around and some of them are going to blow up... much sooner than expected... and some won't. Statistically we know that Jeeps are more prone to failure than other brands, and have higher variations in build quality.

I had a 2008 Sequoia break a valve-spring retainer, drop the valve and eat the motor... 220,000km. It was expensive and made me hate Toyota, though collectively my other Yota's have well over 1,000,000km of trouble-free driving.

So... it's just playing the odds really, that you buy a used motor and have great luck and away you go. Or, you dump Jeep and get something else. Either way, you are resetting the probability of a massive failure. Putting a rebuilt motor in though is way, way more chance of failure than even putting a long-block out of a wreck... People just don't have the same skills they used to have in overhauls... and the tolerances are way tighter... you can get good work done, but it takes time and will cost more. The robot-built motors are simply better value...

Or as in my case, the timing cover and left front axle seal leaked, both well under 60,000 miles on a babied, well-maintained vehicle. And we won't get into goop in the coolant early on.

And to think this one replaced my '12, which was such a possessed, glich-laden POS that I dumped it at the 8-month mark.

I hope to have no more issues with my '13 but it won't surprise me a bit if there are more before I move on to the next DD. I highly doubt I'll buy another FCA product, as the last three haven't been great. I can accept recalls, but no late model vehicle should see a service bay for any repair under 100,000 miles, IMO.

Probably reasonable to speculate that the failure is in some way related to prior work, but since there's no way to ever know or prove anything it's all moot anyway.

For the current situation.... Jasper reman engine, as good as or perhaps better than new, should run around $4k.

I would be very careful with REMAN engines, if it comes to Pentastar.

Pentastar's (and many recently made open deck engines) engine block is different from earlier designs in that it is a High pressure Die Cast engine block WITH cast-in cylinder liners that are spec'd to be NON-serviceable. There are companies that claim that they can despite all service such liners, but their success rate is hard to establish especially if it comes to the long term.
