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.  

My deep scientific research in to this via Google University has 5% showing up across the board. but that rate is based off product use over one year and is for the overall industry, and 15% over 4 years. the only figure I found for Sony was for the PS4 and that was a failure rate of .04% based on the first 1 million launch units with blod . seemingly the leading cause.
