Motor Bricked at 19,600 miles..

The motor in my 2014 WK2 Diesel died in the Service Drive of Glendale D-C-R last Saturday. No reason has yet been given. The service writer I'm dealing with doesn't seem to have much basic knowledge of auto mechanics in general, let alone the strife of the MY '14 Diesel. In her latest attempt to dazzle me with her brilliance she mentioned that while it does need a motor they (the technician) are not sure if it needs a "long block" or a "short block". What does that even mean???


In any case, I'm seeking to talk to a FCA rep who can help me get this expedited. We were planning a 2400 mile road trip in May up to the Pacific Northwest that we're now going to have to do in a rental. Not thrilled.

Hopefully a new motor will final bring an end to the litany of the MY 2014 issues.

Re: Motor Bricked at 19,600 miles..

Very sorry to hear that. I'm not sure if you were asking us the difference between long and short block but I'll chime in. A long block has more accessories than a short block, meaning a long block is more 'ready' to be installed and a short block will need to have major components taken from the donor motor (such as oil pump / pan, valve heads, intake manifold,etc.) The tech may not know if the heads are damaged or if it the failure was contained within the engine casting. I hope that helps.

Thanks Teamsmith. My hope is as much of it is replaced as possible.

Re: Motor Bricked at 19,600 miles..

A simpler definition. A short block is the lower block where the crank / pistons and rods reside. A long block includes the short block and the cylinder head (s) including timing belt / chain assemblies. A complete engine includes the intake and exhaust manifolds and throttle body(s) an often any forced induction system if applicable.

Yup. The indicator was still registering 35% oil life having gone 6700 miles since it's last oil change. I did not get any DIC messages, no telltales, nothing. I was exiting the freeway last Saturday morning and noticed an odd noise that started as some kind of skip, or light valve tap or knock, which progressively got louder to the point it sounded like someone dropped a bolt in a blender. No smoke or leaks anywhere. I located the thread on the TSB for the stuck valve which requires a top-motor rebuild. While the symptoms seem to fit, the service writer said the tech found " a whole lot of metal fragments in the oil pan".

I'm going to try to contact someone at FCA and press the issue on the whole "rebuilt engine" thing. I get there were there were issues with the MY 14 motor, but at 20 months and 20k miles I feel entitled to more than a "rebuilt" motor.

Re: Motor Bricked at 19,600 miles..

first q from fca: when was the last time you checked the oil? Pulled the dipstick and checked?

what does it say about the oil check in the owners manual.

i assume there is some manual check required beyond watching the gauges, but I could be very wrong too.



hope they take care of you properly.
every state is different but might be time to look at a lemon or some type of buyback program.

Re: Motor Bricked at 19,600 miles..

Perhaps your high pressure fuel pump blew itself to smithereens. Engine won't work without that...and metal fragments in the oil pan can be a result. Google VW Bosch diesel fuel pump problems...IIRC, VW claimed the problem is a result of contaminated diesel fuel (contaminated with gasoline) that caused this problem because the fuel pump's lubricant is the diesel fuel...but NHTSA found that this was not the case for most users (in fact, it suggests that for some users, it was determined they had misfueled their vehicles...but for most others it was not the case.)

NHTSA closed the investigation because it wasn't a safety related issues as they claimed...

Interestingly enough, they haven't asked me for anything except for documentation of any service the vehicle received outside of the dealership. That would be one oil change where I purchased the oil and filter (Mobil 1 ESP and AFE Premium oil filter) on Amazon and had my local mechanic do the labor. I'm not a gearhead, don't own a creeper and I'm not interested in getting my fingernails dirty. I know that cuts against the grain of many who post here, but hey, it takes all kinds right?

Now, I appreciate that most of the people here have forgotten more at lunch about auto mechanics than I'll ever know but I do know where the dipstick is. However, absent any evidence to indicate a problem (like leaking, burning, telltale, DIC Message, noise...anything) I'm not inclined to check the oil at every fuel stop. On a road trip maybe, but around town, nah.

As to the last part, I live in California and I'm still trying to determine the teeth in our Lemon Law, but a buyback is certainly NOT out of the question. We really love the vehicle and up until now it's performed flawlessly. Outside of the CAT replacement under recall, there has been no problems to report.

More to come, I guess.

I remember reading in one of the oil change threads on this site that, while many guys here use it, Mobil 1 isn't approved by FCA. I hope you don't run into any issues with that.

I researched it carefully before using it.

Re: Motor Bricked at 19,600 miles..

Mobil 1 ESP certainly meets the spec.

While I'm not seeing a lot of Jeep Grand Cherokee Ecodiesels with engine failure, over at the ram forum they have documented far too many.

GRAND TOTAL as of 04/23/2016
Engine Failures = 56
Oil Cooler Failures = 26
