Periodic steering fluid fill up

For the 3rd time since 2013 I've found my steering fluid reservoir almost empty. Not low, almost empty. I don't remember ever having to refill a steering fluid reservoir on any vehicle I've ever owned, much less three times over the course of 4 years.

Odd thing is that I have not been able to find any leaking fluid at any of the 3 times I've had to refill the reservoir. Anybody else have a similar problem?

 

Nope, sorry OP. Good luck

 

Internal steering rack leak? Any hard steering? Are the boots filled with fluid?

 

Sounds like you have a seal on one end of the rack leaking.
