If recalls were the yard stick for reliability, Toyota and Honda would be the worst or 3rd worst (they flip flopped with each other) the past two years. I'd rather they fix the broken thing for free than spend millions to try and cover it up, like some other supposedly reliable car companies.
Only one warranty-related issue here (water pump replacement, which the Hemi engines are known for). Others have had no issues for over a hundred thousand miles, as ColdCase stated. I know many happy WK2 owners. There will always be some with issues, unfortunately, as they are designed and made by human beings. Sorry that you are one of those unlucky few, and I hope that things get only better for you and your son from now on.
