Joy-Con Issue Not a Defect, Manufacturing Variant!

We got confirmation today via Kotaku that the infamous Left Joy-con issue is the result of a manufacturing variant and not a result of the product design. This aligns with a lot of the videos out there of fixes for the Joy-cons. And it would be surprising if their initial design itself had the flaw in them, considering the amount of UX research (you probably want to find out more about what that is to get a better idea) they must do before even starting manufacture of new products. Not to mention the extensive testing and quality control that the company would implement before release to the market. Therefore, it is very unlikely that the engineers do not carry out UX research process. Larger manufacturing units for companies such as these often tend to use ERP systems to maintain a well-oiled workflow which would include proper quality control checks along with the necessary units made. However, if a company is not as established as Nintendo, implementing an ERP system in a large manufacturing operation can be overwhelming. Seek a consultant dedicated to your space to help manage the details of effectively and efficiently scaling your business while managing your team and your tech. Well, it may be true that in spite of this, errors may crop up sometimes, but in this case, it is supposedly not a major mistake. So if you had this issue, you might want to contact Nintendo and they’ll set you up!

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 at Nintendo use credible quality inspection and quality assurance companies when necessary to make sure production standards adhered to the letter. We do this so that the games and gaming equipment you enjoy is of the highest quality.

It is unfortunate that this manufacturing variation has occurred but we have determined a simple fix can be made to any affected Joy-Con to improve connectivity.

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. Repair timing may vary by region.
