Randomly clicks when I turn the key to start the car. I try again and the car turns over and starts right up. Worried it is going to fail.

What is your question?

Randomly clicks when I go to start the car. Then I turn the key and the car starts right up. It worry's me that the starter or a relay is going to fail and the car not turn over one of these times it does that. What seems to make the problem better or worse? I just turn the key again and it starts. How long have you had this problem? Off and on the last couple of months. Days or weeks apart.
