My son's Sebring is a 2001 with the 2.4, we love it, the thing has been awesome and it's about to roll 155k. When we bought it we were specifically trying to avoid the 2.7.
We had the drain plug problem develop as well, the threads eventually stripped, we just bought one of those butterfly replacement plugs at AAP, it works just fine.
Over time we've noticed his car seems to really like Maxlife, so that's all we give it now.
