Mine does that too.
nothing a little chrome polish cannot fix in the spring.
I work for a Dodge dealer and they are the same.Dodge says road rash...no warranty.
I was going to say the same thing about dodge too. I have an 08 with 30,000 kms on it.
I have a 2010 Chev I keep the truck in my heated shop, It is washed all the time. Rust started to show on my rear bumper. I just had my dealer polished my bumpers and the whole truck last Friday. The dealer said it was from transporting the truck from down east on the train. I do have a speaker making a buzzing noise. The truck was not cheap, But I can't complain it has been a good truck.
Parked in infloor heated garages with no dehumidifier gets alot of people too! They think cause it's heated it's great but its probaly worse!
I like my 07 Classic more and more each day........
Slamnek, they were replacing and bumpers and running boards for free here in town i seen today
