Is rust on hitch receiver covered under warranty?

I noticed this yesterday. Looks like some of the paint is flaking off.

Wondering if anyone knows if the warranty will cover it before I take it to the dealership.

 

That is just surface rust. The Toyota Warranty covers Corrosion, but not surface rust. Hit it with a wire brush, wipe it down, then paint it with matte black rattle can spray paint.

 

Strange question, it's all written in manual and Toyota web site:

CORROSION PERFORATION WARRANTY
Corrosion Perforation Warranty is for a period of 60
months unlimited km. This warranty covers repair of
any original body sheet metal found, under normal
use, to have developed a perforation (hole through the
body panel) from corrosion due to defects in material
or workmanship, subject to the exclusions listed under
Warranty Exceptions.
The application of additional rust inhibiting material
is not required in order to maintain the Corrosion
Perforation Warranty.

CORROSION PERFORMANCE WARRANTY EXCEPTIONS
• Corrosion as a result of a non-Toyota rust inhibiting
material that causes moisture and or contamination to
be retained between the rust inhibitor and body sheet
metal causing corrosion
• Corrosion other than perforation is not warranted
• Corrosion perforation due to external damages caused
by stones, gravel accident or other forms of impact,
industrial fallout or pollution, previous repairs or any
modifications not authorized by Toyota is not warranted
• External surface rust left un-repaired developing into
perforation due to neglect of vehicle care
• Non-Toyota parts and accessories resulting in perforation

 

If you tow at all, the paint on the hitch receiver is going to take a beating. Be prepared to see rust there.

 

Looks to me like it was backed into something, or something hit it. I think this is going to be the dealership's take as well. Just clean it up and paint it. The first time you put a receiver in, it's going to scratch and mar the paint.
