This thread has become more about how MDS functions and why chains break then focusing on the fix to this problem, don't get me wrong, I think we have some great minds on this topic but it's time for theories on how to prevent this disaster from happening to these motors.Ive heard a few ideas, such as - 1) tuning out MDS with the predator- 2) changing the timing setup-3) using autostick. I don't believe dodge will address this mess, so I check in with this thread every day in search of a solution to this problem. So please keep the suggestions coming. Thank you all for your input so far. I do not want to get rid of this car, still hangin on.

I agree, the only fix will be from the aftermarket, if any. Allpar and several other sources tell the tale on how the MDS system was tested and only 5 percent of the buying public would exceed their benchmark. Are we witnessing this 5 percent? Every case thus far has cliaimed the failure happened while cruising at or around 70mph, most likely in MDS mode. A question that needs to be asked is how much of your daily commute is in MDS mode.....
I my case, I drive 122 miles round trip per day, on very flat terrain. I pop the cruise control on at 80mph and the car stays in MDS mode 99% of the time. Does that put me in the 5 percent club?? I can speak only on my challenger, but my MDS will engage at 90mph, as of where my wife's 2010 Ram won't engsge past 80mph..
And as far as Chrysler's testing goes, they claim testing cycles of over a million miles, etc...... The testing miles they speak of are based on calculations and projections of wear, not actual. The timing chain failure was never an issue while testing and analysis was evaluated, due to the fact it wasn't actual miles???? I'm guessing.......
And I'm with you, I have no intention of getting rid of the car, overall it is a fantastic automobile despite of a few flubs. The new Gen Hemi is a great engine, it could be a bulletproof package if A: the timing chain issue is corrected B: the SRT rods were used, C: forged crank and pistons with a sane ring width replaced the cast ones.
