• 13-inch MacBook Pro (non Touch Bar) Battery Replacement Program
  

  "Apple has determined that, in a limited number of 13-inch MacBook Pro (non Touch Bar) units, a component may fail causing the built-in battery to expand. This is not a safety issue and Apple will replace eligible batteries, free of charge. Affected units were manufactured between October 2016 and October 2017 and eligibility is determined by the product serial number."

  The linked page has a serial number checker. Affected owners that paid for a replacement battery can get a refund.
