Does the 2017 Ultra Limited have cooling issues? Shortly after buying my Ultra the cooling fan motor went out, that was in September 2017. Today I had liquid on the right foot board after a short ride (10 minutes) and have a low coolant level. Any ideas?

 

I don't think "they" do, but yours clearly does.

 

Not that I know off, I've heard of loose clamps on the coolant hoses causing leakage.

 

It is a machine built/assembled by humans.

No matter the brand or model, there will always be a certain percentage of them experience some type of issue.
That is why all manufacturers offer a warranty.
