Here's an update from the issue eof my front bumper rusting.
The Dealership took a look at the bumper, took pictures and let the area manager know too. They also directed us to Chrysler Canada to submit our defect in the truck. This is all normal "protical", so recalls can be started for this make,model ect.
While all this was happening, it ended up taking 2 weeks, for them to get the okay, to move forward and replace with a new bumper at no cost.
After having the bumper rusting, I'm sure it would have buffed out with metal polish. The rusting I think, and from reading into this more, might be metal flakes from shipping because the bumper is not protected. It seems if the trucks are moved by train/rail, the brakes from the train cars while being shipped throw alot of metal "dust" up, which lands on the front of the vehicals while being shipped. So the rusting is actually not the chrome, or under the chrome. But bare metal dust rusting on top of the surface.
I'm not 100% sure, but to me it does make some sense. The chroming on the bumpers doesn't seem to be cheaply done.

 

09 here and chrome bumper as good as new.

 

When I first climbed under my 2010 Ram to do some work I noticed how badly rusted my front bumper was on the inside. Now I've got spots rusting all over the front of it.

 

Finally got around to washing mine and I've got rust spots all over the front bumper. Odd that I didn't have this problem last winter, but its pretty bad now. Once it warms up a bit more I'll have to see if any kind of polish will take care of it. 47K on the truck so it won't be a warranty item fo rme.

 

I wish I took pictures but I haven't been out much this winter and the truck hasn't been clean often although it has been washed but by the time you get home it's white with salt but we had it washed and actually have it washed at the dealer they have a 20 dollar special inside and out. What I find interesting is my Chrome clad rims corroded....sorry to but into your post here since I posted about this but I wanted people to watch their rims also, I went in day before yesterday to show them, they replaced them yesterday...warranty.So a rusty bumper should be warranty no problem.

 

vette68 i had same problem on my 4x4trx cc blue/gray. pitted rust on the front bumper. dealership manger emailed dodge and dodge told them to replace bumper. no argument, no discussion just good service from blevins motors in potsdam ny

 

I have been in contact over the phone with Chrysler Service about both our chrome bumpers and the chrome clad wheels on my wife's 09. The Chrysler Service Rep. tried for several days to text and call the service manager at our dealer. They finally did talk and now I am suppose to take the truck back in again for more pictures. Well, I won't be taking it back in till Spring is here. Also, the Chrysler Service Rep. danced around the warranty on the replacement chrome. I told the Chrysler Service Rep. that if the 2011 Rams have chrome problems, why would I want them replaced until the chrome problems are corrected. We just turned 12K miles and have over a year of warranty remaining.

 

vette68...I purchased my 2011 truck in Nov 2010. In 3 weeks my front bumper looked like yours. In 2 months the front looked like it was 15 years old. Then the rear started to rust as well.
Just had the rear bumper replaced by dealer and the front will be replaced by dealer in a couple of weeks, all warranty.
Rail dust is what I was told, which someone already said. Take it in, get them to take pictures and make sure they start a claim for you (lesson learned) and then keep on them. Squeeky wheel gets the grease.

Good luck

 

Soooooo......Here's an up date, to my up date.......
The replaced front bumper is now rusting as well!
So I am going to rule out rail dust, I'm quite sure the bumpers aren't shipped openly on the railways.....

 

Yeah, you never see rusted chrome in south Louisiana---I noticed that everyone with the problem is from a state where the roads are probably treated for ice & snow.
