If the cars still under warrantee have the a chrysler dealship check them out, i had my o5 srt6 headlight units replaced and where covered by the warrantee, mine had hazing, continuous moisture, and minor discoloration, they were twice as bad as my 98 corrolla. dealership stated they had very poor seals which are a common problem with the car. not sure if thats what you meant by cosmetic damage but good info for anyone else with a similar problem.
