Has anyone seen this on the RDX models indicated in the pic?

 

That doesn't look like an RDX. Definitely NOT 13-15 model years. Possibly 16-18?

 

That looks just like mine and I drive a 2017 RDX Technology package.

 

2017 RDX Elite...

 

The photo is generic, not meant to represent a particular model. One would go by the part number. The photo you show is for a "warranty" part number. Those are probably rebuilt by the
vendor and used by dealers for warranty replacements. There is a different part numbers for a brand new one.
