Tesla to Upgrade 4M Older Vehicles for Full Self-Driving

Elon Musk announced that approximately 4 million Tesla vehicles manufactured between 2019 and 2023 will require hardware upgrades to achieve unsupervised full self-driving capability. The affected cars lack sufficient memory bandwidth in their current computer systems. This admission addresses long-standing concerns about the limitations of older Autopilot hardware. Owners of these vehicles will need to retrofit their cars with new computer modules to access future autonomous driving features. The upgrade program's timeline and costs have not been detailed.
