Nintendo Switch Joy-Con Controller Issues Caused By Manufacturing Variation; Issues Won’t Be Present Moving Forward


Since the console's release earlier this month, several Nintendo Switch users have had to deal with some Joy-Con controllers issues, with the left controller having signal issues. Now it seems like the Japanese company discovered the reason behind the issues, which shouldn't present themselves moving forward.

In a statement sent to Kotaku, Nintendo of America confirmed that issues were caused by a manufacturing variation. This variation has been addressed, and issues shouldn't be there from now on.

There is no design issue with the Joy-Con controllers, and no widespread proactive repair or replacement effort is underway. A manufacturing variation has resulted in wireless interference with a small number of the left Joy-Con. Moving forward this will not be an issue, as the manufacturing variation has been addressed and corrected at the factory level.

We have determined a simple fix can be made to any affected Joy-Con to improve connectivity.

Nintendo also acknowledged that there may be other issues behind wireless interference, asking all customers experiencing issues to contact Nintendo.

There are other reasons consumers may be experiencing wireless interference. We are asking consumers to contact our customer support team so we can help them determine if a repair is necessary. If it is, consumers can send their controller directly to Nintendo for the adjustment, free of charge, with an anticipated quick return of less than a week.
