Elon Musk admits that millions of Tesla vehicles won’t get unsupervised FSD

Tesla has confirmed that approximately 4 million vehicles with Hardware 3 processors cannot support unsupervised Full Self-Driving capability due to insufficient memory bandwidth, leaving customers who purchased the feature locked out unless they undertake expensive hardware upgrades. This represents a significant product delivery failure with substantial customer trust and financial implications, requiring Tesla to establish new manufacturing infrastructure to retrofit vehicles at scale. For IT and technology leaders, this case demonstrates the critical importance of validating hardware sufficiency during product development and the substantial operational and reputational costs of platform obsolescence management.
