There is no situation where a 1% defect rate that would create a warranty claim within 90 days of purchase of a mass produced product is acceptable.  That's about 10x what most companies consider acceptable (though the accepted level varies by product type).  

That being said, I seriously doubt that 1% of Dualsense controllers are having this problem this close to launch.  If so, that would be pointing to a disaster in the long term, as the controllers age.  

Also, it does not seem likely that there are anywhere close to 15mm Dualsense controllers in the wild at this point.  

Are you sure? I've always heard %4-5 as being acceptable when it comes to electronics. Do you have any sources?

I don't have any specific sources to link you to. My info comes from my understanding of manufacturing practices.  

When you hear talk of 4-5% being acceptable, that's generally something that doesn't impact the ability of the product to do its intended job.  So, on a video game controller, it might be something like the X graphic on the button is slightly misaligned.  Things like drifiting analog sticks essentially render the controller useless, and result in a return or a warranty claim.  For those kinds of things, you're generally looking for less than O.1% defect rate.  I manufacturing in general, the goal is typically <0.075%.

Note that I have not studied manufacturing of video game hardware in particular.  So, it is possible that a bit more than 0.1% is normal.  I see no chance that 1% is considered acceptable though. That would be hugely expensive, and expenses like that are not tolerated in modern manufacturing.
