I had a '12 rt that threw a few codes that correlated to timing chain replacement. My car was at 26k miles when it did this, and I was surprised to see it was an incredibly common occurrence. Theres even an article on Hotrod.com about it. Anyways, you have to go to chryslers recall web site and type in the vin number in the designated area. I thought all RTs were covered, they're not. Its a huge load of bull$hite. Best of luck.
