Elon Musk, the CEO of Tesla, revealed during the company's Q1 2026 earnings call that a significant number of vehicles will not be upgraded to the unsupervised Full Self-Driving (FSD) feature.
Approximately 4 million Tesla vehicles are impacted by this limitation, which is attributed to the Hardware 3 (HW3) computer system.
