Tesla CEO Elon Musk said the company will upgrade HW3 self-driving computers for owners who have purchased its Full Self-Driving (FSD) package, marking a key update for customers using older hardware.
Speaking during Tesla’s fourth-quarter 2024 earnings call, Musk confirmed that all vehicles equipped with HW3 would receive an upgrade to new self-driving computers. However, he specified that the offer would apply only to customers who purchased FSD outright, not to those who subscribe to the service.

“The honest answer is that we’re going to have to upgrade people’s HW3 computer for those that have bought FSD,” Musk said. “It’s going to be painful and difficult, but we’ll get it done.”
Tesla introduced HW3 in 2019, featuring custom AI chips designed to process real-time driving data. However, with the rollout of its more advanced HW4 hardware in newer vehicles, HW3-equipped cars have fallen behind in software capabilities.

Musk did not provide a timeline for the upgrades, but the transition poses logistical challenges. HW4’s design differs significantly from HW3, making a direct swap impractical. Tesla may develop a modified HW4 system that fits HW3 vehicles or create a hybrid solution with increased processing power.
Camera compatibility remains a question, though Musk previously stated that existing cameras are “capable” and will not require replacement.
For Tesla owners, the biggest challenge may be scheduling service appointments, as retrofit requests could strain existing service center capacity.

Musk clarified that the upgrade will not be available to those subscribing to FSD at $99 per month. However, Tesla may expand eligibility in the future, potentially offering upgrades for a fee. Based on past computer upgrades, costs could range from $2,000 to $3,000.
