the 5.7L found in the Challenger is the same engine found in the Ram, Charger, 300 & Grand Cherokee, not that many Challengers around, but that engine is out there in large quantities, last time i spoke to my field service engineer, questioned him regarding timing chain failure, he stated never even heard of one failing, does it happen probably, but 3 out of several million engines, does it matter....nope
Nobody said it was only 3 that failed. I find it strange that 3 people found and posted to this thread with the same problem in less than a month. If every owner of a HEMI was on this forum and posted and there were only 3 with problems that would be one thing...but 3 people out of a small percentage of the market, represented by the forum, isn't a statistic anyone can go by...other than there ARE people seeking out others that had the same problem.
Am I worried? No. My Ram hasn't had any problems with the DPF plugging up or the turbo getting stuck, does that mean the multitude of people that have are just subject to the "Bummer, crap happens" attitude? I appreciate that you're here and have as well as provide a lot of insight into what's going on, but on the flip side I think you're being too quick to shrug this off as a random problem simply because you haven't seen it personally. I've never seen a tornado here in southern California, but I know they've happened.
This timing chain problem is too coincidental to be a random, crap happens problem.
all you have to do is talk to any tech in a large dealership, he'll tell you in a hurry the issues we have....the new gen hemi's are kick ass engines, any engine pushed to the limit can and will break, doesnt necessarily make it a bad engine...
I agree, the HEMI is an awesome engine. However, having worked at a shop that did warranty work for a German auto maker, I can also tell you that a lot of common problems can be regional. Being the only shop in northern Arizona to provide warranty work, we were pretty busy. One of the most common problems we'd see were timing belt failures before they were supposed to be replaced at 60k miles. We literally had a continuous pile of heads sitting out back waiting to be shipped back to the manufacturer. Now, had you asked a large shop in another region that wasn't in a hot, dry area if they see a lot of premature timing belt failures the answer would be no.
Of course, these timing chain failures aren't a regional problem but my point is simply that you can't take a sampling of one or two shops, or one region, and apply your findings to everyone. If you were in Phoenix and never saw problems with the keyless door handles failing because it never rained, would you be quick to state there's no problem and they must be isolated and not a real problem? I'd hope not.
There are 3 documented problems in this thread alone in less than a month. I wouldn't be so quick to blame it on simply being a random problem or due to "operator error" because the engine was pushed too hard. That's rather presumptuous on your part and those impacted that haven't driven their car hard might take offense to such a statement, or even feel like you're sounding like a "typical dealer" that's "part of the problem."
Our local dealer tried to pull the same thing on my wife and I about the brakes on her Caravan. "Nobody else is having these problems, you must not be driving properly." Awesome way to make someone's blood boil, especially when the problem is well documented.
Like I said, I'm not saying this is a widespread problem, but CLEARLY there are people having failures and that simply needs to be acknowledged and not blown off as random or customer fault.
Would you consider it random of 3 people posted on here within a month that said their left front wheel fell off? That's a pretty major thing to happen, and pretty specific to be random, don't you think?
