What might cause this?
Similar symptoms can have different causes across models and software versions. These are possibilities, not a diagnosis.
Possible causes

If the buttons still fail, do not disassemble the Joy-Con; contact Nintendo support.
How can you confirm the fix?
Joy-Con buttons respond consistently in the button test and game menus.
When should you contact service?
Seek Nintendo service for physically stuck buttons or persistent failure.
⚠ Stop using a device if it overheats, shows liquid damage, smells burnt or has a swollen battery.
Will a repair cost money?
Settings, cables and user checks may require no repair. Hardware costs depend on the exact model, warranty and service diagnosis; no fixed price is promised.
Quick answers
Could these checks affect warranty?
Use only external checks recommended for end users by the manufacturer. Opening batteries, electronics or sealed parts can create safety and warranty risks.
What if the steps do not help?
Write down your model, software version and test results. Share those details with official support rather than repeating potentially unsafe actions.
