Separately, Tesla told a California regulator it may not achieve full self-driving technology by year-end, Reuters reported, citing a memo written by the California Department of Motor Vehicles.
Tesla Chief Executive Elon Musk had said in January that he was "highly confident the car will be able to drive itself with reliability in excess of human this year."
Tesla since October has also rolled out what it describes as a beta version of its full self-driving program to a limited number of employees and customers, Reuters reported. Musk also has touted the capability on Twitter.
"Elon's tweet does not match engineering reality per CJ. Tesla is at Level 2 currently," the California DMV said in a memo about its conference call in March with Tesla representatives, including autopilot engineer CJ Moore.
Level 2 technology means the car can steer itself and accelerate but the driver still must be ready to take the wheel.
The memo was released by legal transparency group PlainSite, which obtained it under the Freedom of Information Act.
Musk, meanwhile, will be hosting "Saturday Night Live" this weekend.
