A:Answer Yes, geek squad can fix it. Unfortunately, joy con drift is common. You can also try to send it to Nintendo they used to do free joy con repairs. For information on how to do that check this website: https://www.ign.com/wikis/nintendo-switch/How_to_Fix_Joy-Con_Drift#Send_it_to_Nintendo_for_a_free_repair_.28.2Fget_a_refund_for_previous_repairs.29
Info from the website:
Here's how to send your Joy-Con in for a repair:
go to support.nintendo.com/joyconrepair
submit a ticket
Here's how to request a refund for a previous repair:
call in (US & Canada) to 1-855-548-4693 to get your refund.
You can send in multiple Joy-con with one shipment. Again, the only downside is that Joy-con that can't be repaired may result in a replacement of a different color.
