Tesla’s autonomous driving system is in doubt amid a battery issue, a software engineer who has been with the electric carmaker said on Friday.
In a tweet, Tesla’s CTO, John Krafcik, said the software “is not performing as expected,” and that the Autopilots Autoplay system has been disabled.
He added that Tesla is “evaluating” Autopillering, an in-vehicle system that helps the car determine where it should and should not be driving.
Tesla is the only automaker with a fully autonomous driving feature that uses computers to detect and avoid obstacles.
The company has not said what caused the problem.
Krafcik said Autopilt is a program “that runs continuously,” and Tesla is using it “to improve performance and safety.”
He did not specify what the Autoplayer program does, but Tesla said it “provides autonomous driving capability for Model S, X, and XR vehicles.”
A spokeswoman for the National Highway Traffic Safety Administration did not immediately respond to a request for comment.
