They usually don’t put a lot of paint on the axle housing. Sterling axle builds & ships to Dearborn & KC plants I would just get some rattle can & spray it, if it bothers you.

... second two are under my 16-year-old Expedition. Notice any difference?

While agreeing that the amount of rust on a lot of the new F150's is completely unacceptable, the two pictures of your 16 year old Expedition are focused on parts that appear to be aluminum castings.

You know, these are probably early builds. As such, I wonder if some of these parts were not JIT and instead stockpiled and stored outside in the weather. So rusting away for at least a few months as Ford tried to start production of the new truck. I’m sure the new Bronco may see similar with all the production delays. Where have parts like frames and axles been stored in the meantime?

I’m debating on whether to get my new truck treated at Ziebart. Most all the rust was wire brushed off, but there’s still a little showing. I live in Dallas, so not an area known for rust. Should I get it treated or just chill? I have zero experience with Ziebart - not concerned about the $, but wouldn’t want them to screw something up.

Look at muffler and exhaust pipe...zero rust.

For some, thick metal under carriage rust on a brand new vehicle is a nit and should be expected. Sure, it would be nice for them to spend $3 on a quick coat of enamel for a $60K truck but I guess I'm expecting too much from Ford where every nickel counts.

But when you look at the other parts of the exhaust system that have rust already, that is a bit alarming. If they aren't using stainless steel or even aluminized metal on exhaust components and hangers these things will disintegrate in a few years in the northern climates. Perhaps Ford is expecting everyone to put an aftermarket exhaust on their truck.

Comparison to other new trucks. At about 9:10 he starts looking under brand new 2021’s.

Now, THIS is a dealer the way they should all be!!! (y) (y)

The early builds were run back and forth from one storage area to who knows where else. No doubt with salt on the roads, completely covering the underside. As I mentioned, my truck had something like 63 miles on it when I picked it up. I still would not expect as much rust as what some of our trucks have.

Fixable? Absolutely!

Who should fix it? No doubt Ford should cover the cost to put it back to what is expected.

Replace parts? Don't see that happening nor would I want that to happen to my new truck. The rust is not deep but excessive and should be cleaned and painted to the degree it is protected.
Hummm, not sure I would go that route. In fact I know I would not. You can create some other issues replace the pumpkin and axles.

Think I would go for rust removal and repaint.
I’m thinking of doing the same. As you can see my rust is just surficial and not as bad as others.

Picked up my Limited today (3/4). Built on 2/27, delivered to dealer on 3/2.

11 miles on the ODO, and coming from a long-in-the-tooth 2010 F150 Lariat, I absolutely love it!

Rear differential was pristine, as was the entire vehicle.

This is what my 2020 looked like and what I would’ve expected for my 2021. Not the rust bucket crap we have that looks like they were driven through a corrosive acid puddle immediately after they came off the production line!

With your area not being a snow and salt type environment, I would say that would be a waste of money for you. I would get some quality high heat (engine paint) and hit those area's with a couple coats of the paint. Don't have to be pretty, you just want it well covered and you will be just fine for many many years.

You can see by the brake bolt the steel looks bare with no paint, the same place that is showing rust on many of the trucks. You'd think they could put a little better paint system on these components so they wouldn't rust so quickly.
