I have a 2011 Ram 5.7 Hemi that I bought used a year ago. When I bought it, it had a tick to it but wasn't bad. Just within the past couple weeks ot got a lot worse. It lost power, mpg went down, and was dying when I turned the wheel while idling. I took it to a local service shop and was told it was it was internal so I had it towed to my local Dodge dealer where I was told it was the cam and a seized lifter. Lucky for me I bought a powertrain warranty. My question is, has anybody had this problem and had it fixed and it come back again? Thanks for your help.
