I have been finding many reports of the timing chain breaking on the Dodge Challenger, mostly in the 5.7L Hemi engines. The timing chain breaks in most reported instances around the 35K-40K mile range.
Once the timing chain breaks, the end result is usually the valves smacking the pistons which bend the valves, damages the pistons and leads to catastrophic engine failure. This often requires a new long block.
How many of you have had the timing chain break? How many miles on the car when when it happened? and what was your experience in getting it repaired?

lost it on the interstate doing 73 in MDS
The things in common when the timing chain breaks so far are:
1. MDS is activated (auto trans., so 6-speed are excluded)
2. Traveling at freeway speeds
3. 2009-2011 model years affected so far.
4. Limited to the 5.7L motor so far
5. Dodge Challenger only
Things ruled out thus far:
A. 6-speed manual transmissions not affected
B. Other 5.7L vehicles not affected, i.e., Charger, 300, Ram truck
C. New tensioner (white color) has also failed (see #8 on list of failures)
D. New crate motor has also failed (see #3 and #8 on list of failures)
E. Both stock and mod cars affected
F. Both stock tune and Predator tune (with MDS turned on) affected
G. All oil change intervals affected, i.e., 3,000 miles, 5,000 miles, etc.
H. All types of oil affected, i.e., both synthetic and conventional oil
