Doesn't Nintendo generally do well with replacing/fixing left joycon drift, though? I hope so, as mine's starting to get too annoying to use when I'm playing Smash with my roommates.

You can recalibrate them in the settings, it usually does the trick.

When that doesn't work, try a can of air, or if you are hardware and electronics savvy, take it apart and give it a real good cleaning.
