Has the motor on a 2013 gmc terrain been recalled for an oil leak?

Hello, for any concerns with "recalls", you should consult your local GMC dealership and provide your Vehicle Identification Number (VIN) for them to look up and see what kind of open recalls your vehicle may have. Note that "safety' and "emissions" recalls differ from owner notification programs where warranty is extended on certain components for a certain period of time for customer satisfaction purposes. I highly doubt you have an oil leak that is covered by a "safety" or "emissions" recall; it is far more likely - if anything - to have coverage from some kind of other program. Good luck!
