The e53 may have a lot of annoying issues but NOTHING as serious and dangerous as a crystler product. I had an 08 grand Cherokee and the front differential seized up at 70mph stopping it instantly. My friends jumped out and refused to ever ride in it again. It had about 43,000 miles on it when I got rid of it and bought my current 02 4.6is that now has 130,000 miles on it and am living every single moment with it.
