I got a email from my service center. Good afternoon ____, Your Tesla was built with the world’s most sophisticated software which includes Tesla auto-pilot hardware. One feature of our auto-pilot will allow your vehicle to brake autonomously. There is an updated part to this feature we would like to install on your vehicle as soon as possible. Tesla is proactively installing this part on all applicable vehicle with the auto-pilot hardware. We would like to schedule this as our earliest availability will allow. Please contact us via any means below so we can schedule you in. I already have the current model s autopilot sensors and software, what could this be?
