13 pentastar tick

Ok so I checked out the thread on the ticking 3.6 I didnt read all 144pages of it tho. Does the 13 have the tick issue also? We've got about 900 miles on so far and it seems like it idles louder than it did at first. It doesnt sound anything like the video I watched, more like a lifter wearing out.

Maybe Im being paranoid after my last Dodge thar EVERYTHING broke on.

What's the build date on the door jam? The ticking problem was supposedly fixed with the 2013 models but a few very early builds might still have the old head from the 2012 models.

There were three designs, the AA, AB, and AC. The ticking seems to be only occurring on the AA head - at least last I heard. The AB was a short run, then AC started and continues now.

Read this thread, it explains how to ID the head. I also noticed a louder noise until about 1500 miles.

I've got a '13, build date of Feb 13, no ticking so far with 2800 miles on it.
The Air Force FINALLY sent me back home to Florida. Ahhhh, Emerald Coast sugar sand.

Both of our 13's idle loud if listened to while sitting in between other vehicles or in the garage. There is the usual, extremely loud, injector ticking as well as other ticking. After experiencing these same sounds, most likely lifters, in modern vehicles like an '05 Mustang GT, '07 Benz SLK and '09 Accord, I've come to realize ticking is very common on modern vehicles.

If I were you I wouldn't worry about it. Watch for the engine light and if it comes on then take it to the dealer.
