Have any of you had any problems with the plug hole threads on 2nd gen oil pans being stripped? My neighbor (a Chrysler mechanic) says he has seen it before because of the all-Aluminum engine. I'm suspecting the Jiffy Lube guys might have used an air tool on the plug or something. I think I'll be changing my own oil from now on. I'm curious if any of you have had similar problems. Thanks!
