Probably the first questions would be:

1. Was the vehicle stock when it happened?
2. Does the vehicle have any mods?
3. What oil is being used and when was it last changed?

I'm going to wait and see if any failures show up in 6-speed Challengers. Until then, I'm keeping my car (and my fingers crossed).

Exactly right. No difference between the 5.7L and the 6.4L engines. They both use the exact same set up, i.e., same MDS, timing chain and tensioner.

Based on the average annual miles driven by most people (15,000 miles), I figured we would be well into the first part of 2013 before we'd start seeing reports of the 2011 5.7L and 6.4L begin rolling in.

Just waiting for the first 392 report to come in now.

Probably time to trade this POS in on a truck, like I should have bought in the first place.

And when I DO trade it in on a truck, I want to see a timing chain from the engine FIRST.
There's no reason to think there will be a failure with a 6-speed car, there have been zero reports of TC failure with them. It's only been with autos with MDS.

I have a 400 mile round-trip I need to do this weekend. Should be a beautiful, sunny, warm and dry late summer / early autumn weekend in northeastern Wisconsin. Just the kind of weekend you'd like to take your cool Hemi Orange retro-musclecar for a spin with some Rammstein cranking on the tunebox.

You know, like I had planned all along.

I shouldn't have to worry about a goddam busted timing chain.

NONE of us should have to worry about a goddam busted timing chain.

The 5.7L TC is still weak and spindly looking.

Oddly, so is the OEM TC for my 5.3L GMC truck motor (with 136K on it).

Agreed, but if you live your life waiting for something that hasn't happened to any 6-speed cars then you're going to be miserable. Likewise, if you have an auto you'll still be miserable because this problem isn't happening to most owners, only a small percentage of them.

Does it suck? Yup.

I'm not going to live my life based on "what if" scenarios, that's no way to live. I am happy that I have a 6-speed, I'm not worried one bit about busting a timing chain. Even if one person with a 6-speed had a chain break that still wouldn't stop me.

Your choice. Keep it and enjoy it or get something else and not have to worry about the TC (No promises that whatever else you buy won't have some other problem). Keeping it and worrying about a problem that hasn't been documented yet just isn't something I'd do.

Can't judge a book by its cover. Pretty sure I've read somewhere that the revised TC in our engines is actually stronger than the previous one even though it looks like it shouldn't be.

I'm not going to "worry" about the TC issue either, and I've got the automatic that's just hit 24k. I'll fight that fire when it happens.

Last week I did a 2k Colorado "road trip", and it was the most fun trip that I've taken. The Challenger is just such a great cruiser, and going through the Rockies in it was a blast.

I wouldn't want a breakdown there, but there could be worse areas to "get stuck in" LOL

I'm going to enjoy this car to the end

Statistically these numbers are still too low to draw any conclusions (for us) yet anyway. Yes, there seems to be a common theme here: MDS (keep in mind though that MDS worked fine in the first gen HEMIs). I still believe most of us (other than maybe DesertBum who has done his own repair) have enough information that goes beyond anything but speculation. Hopefully Chrysler though has more info by now and is looking into this. These kind of investigations need time. The last thing you want to do is make things worth with a fix that wasn't... And I agree with Yahooligan: Can't judge a book by its cover.
