unfortunately no, there isn't anything that tracks membership expiries and allows for the sending of a reminder email built into the memberships add-on. All it does it create the new user, add them to the groups necessary and send them an email with their login details. Anything beyond that opens it up to a whole range of different options and complexity, I didn't see an appropriate way to add it as a feature.
Where I've needed this kind of thing for projects, I've actually looked to add a person's details to a bulking emailing system like Mailchimp or Sendy when they enter a user group - that emailing campaign is set up to email them at intervals throughout their 'membership' period (often called a drip campaign). That avoids several issues of sending lots of email from a web server, having to run automated jobs, allowing you to create nice looking emails etc.
This did require the development of a custom package though, it's not overly complicated, but it is a coding job.
The other thing to consider is that in more sophisticated membership systems renewals tend to work out pro-rata prices depending on how much time you have left on your membership. As this uses concrete5's user groups, adding a members to a group again doesn't _add_ another year of time to membership, it simply resets it. So with something like this it's more a case of only allowing someone to renew after their membership period has elapsed. This can be handled quite nicely by using permissions that hides whatever content/blocks that allows membership to be purchased.
Memberships with reminders and renewals is something I've tried to tackle with concrete5 in the past, but it's a real headache. I'd recommend keeping it very simple with whatever option you end up with!
