Yeah I saw that, yet we've had that motor here in Oz since 2011 and I haven't heard of this failure happening here yet.

Biggest kms on one I can find 263k:

From what I've been able to research about it, is that it's not a lubrication issue, but rather a manufacturing one. From what I understand this gear is a press fit on to the camshaft. Depending on the degree of "press", which can vary because of manufacturing tolerances, determines how tight of a fit it is. If the camshaft bearing surface is on the low end of the tolerance, (small side), and the hole in the sprocket is on the high end, (large side), the fit can be loose enough that the sprocket can slip on the shaft in time.

This of course throws the cam timing out the window, and the engine basically self destructs, destroying the engine. (Pistons, valves, and possibly the cylinder heads). Resulting in very expensive repair costs. I've heard of this happening to engines with as little as 20K on the clock. Or as much as 148K. And just about everywhere or anywhere in between. A "ticking bomb" so to speak. Needless to say, between that and the lack of a lifetime warranty, I walked away from the Eco Diesel option, and ran to the HEMI. So far I'm very pleased. (Especially with plummeting gas prices). I wish the Eco Diesel owners well, and hope Chrysler / Fiat comes up with a warranty fix soon. There is a lot of money, as well as peace of mind riding on this one.

I do not like the sound of V6 engines, so will not buy any vehicles equipped with them.

I know what you mean. I was close to buying a V6 till I test drove the V8 and heard the rumble in cabin from that engine.

At some point, that will become difficult...but I do understand the sound thing!

Re: The end of V8 Hemi in 2019?

The Harman Uconnect system will make the V6 sound as good as the Hemi inside the vehicle via sound simulation tied to engine rpm.

BS in my mind, but what's coming.
