I just had this fixed under warranty. There is a TSB on it, so take your car in now. I drove with it since I owned the car, and I cannot explain how much better the car runs now that I took care of it. They replaced all the lifters for me and I actually have acceleration the way the car was supposed to accelerate.
I've had no more ticking and my gas mileage is way better as of late. Take it in soon, should only be a one day fix (I got mine fixed when I was at work).
