Microsoft's Xbox 360 had a 54% failure rate — the $1.15B Red Ring of Death

Microsoft launched the Xbox 360 in November 2005, a year ahead of Sony's PlayStation 3, capturing a crucial head start in the console wars. But the rushed development left a critical flaw: the GPU's C4 solder bumps cracked under thermal stress from repeated heating and cooling cycles. The soldering used a combination of high-lead bumps and low-temperature underfill that IBM and Amkor had warned was unreliable. An engineer requested a production line shutdown before launch; management denied it.

Consoles began failing almost immediately. The 'Red Ring of Death' — three flashing red lights around the power button — signalled a general hardware failure. By March 2006, about 30% of manufactured consoles had been returned or had failed factory checks. Failure rates ranged from 16% to 54% in independent surveys. The crisis deepened for nearly two years before Microsoft acknowledged it publicly. In July 2007, Peter Moore published an open letter extending the warranty to three years for all consoles with general hardware failure.

Microsoft took a $1.15 billion charge to cover the extended warranty, of which $240 million was FedEx shipping costs alone. CEO Steve Ballmer approved the expense without hesitation — Peter Moore later said that without that decision, 'the Xbox brand and Xbox One wouldn't exist today.' Microsoft redesigned the GPU with a proper underfill, and the Falcon and Jasper motherboard revisions (2008) brought failure rates below 4%. The Xbox 360 S (2010) eliminated the problem entirely. The full technical root cause was not publicly disclosed until 2021.
