The 2007 Aveo LT Sedan has silver painted plastic interior door handles that has been wearing off. I think there's a service bulletin on this. I've been advised that GM is about to release into their part's inventory, newly improved door handles so this won't happen again - hopefully. The bad news is - I've been waiting almost a month to be told that the parts are now backordered due to improvements. The problem also is with the door handles in the Cobalts.
