Tesla continually improves their vehicles with over-the-air software updates that include enhancements to Autopilot and Full Self-Driving (FSD) features in the future.
How Often Do Firmware Updates Occur?
Tesla continually rolls out updates to vehicles. They typically test new updates on a smaller set of vehicles first (e.g. 1,000) to ensure there are no issues ‘in the wild’ before rolling firmware updates out to the broader fleet. How often your Tesla is updated depends on your patch cycle. Each car typically has a 30 to 60 day patch cycle, which means that you may not get every incremental update. This ensures the fleet is relatively heterogeneous and not prone to single-bug failures.

Listed below are recent software updates with notable Tesla Autopilot improvements.
