Q: Logic board failure

I own a late-2011 MacBook Pro model, infamous for its logic board failures. In 2015, my MacBook quit displaying properly, let alone booting. I took it into my local Apple Store and they were able to diagnose the issue as the logic board having failed. they replaced it, free of charge, and I had high hopes that that was the end of my worries. Lo And behold, my MacBook has begun having several kernel panics at random times, making schoolwork a hassle. At this point, is it even worth returning to the genus bar? Or should I give up and replace me entire system with a new model?
