They would also be refunding gamers who sent their controllers in for repair and paid the repair costs. However, it seems that this might not be applicable to all regions around the world. According to UK website Metro, it seems that this repair policy might not be applicable to the UK. This was further confirmed by a post on Reddit in which a user tried to ask about the free repairs, only to be told that it seems that it might only be for gamers in the US.
According to the post, “Unfortunately not… A statement was released by Nintendo of America acknowledging known issues with Nintendo Switch Joy-Con controllers. Our Nintendo UK process remains the same – to provide recommended troubleshooting.” However, other users in other parts of the world, such as the Netherlands, have reported that Nintendo will repair the Joy-Cons for free and will waive shipping costs.
This means that depending on where you live, you may or may not have to pay for repairs, so maybe it’s a good idea to reach out to your local Nintendo and see where they stand on these repairs.
