I have 2012 300c awd. My favorite car ever, but at 95k miles I'm concerned. She is noisy on cold starts. Hemi tick and it lasts for a couple of miles.
I also have a 2012 300C AWD. Mine also has the tick. But that tick is piston slap. That has been normal for years even on the GM V-8's. Mine has 60k miles. I'm not worried about it thoug. Keep the oil changed every 4K with synthetic and all will be good.
I personally think the failures are from lack of maintainance, extended idling, and abuse. Most of th failures we see are in trucks, a couple in cars. I know one year we had about 6 failures. 4 were in 2500 trucks and 2 were in cars. Rarely do you hear of a Grand Cherokee or Durango with a failure.
