The California Department of Motor Vehicles has accused the company of deceptive business practices over its marketing of what it calls its "Full Self-Driving Capability."

According to the complaints, the marketing claims the cars function with "autopilot" or "full self-driving" capabilities, suggesting that the vehicles operate autonomously.

"All you need to do is get in and tell your car where you want to go," an advertisement for the company said. If you don't say anything, your car will take you to where you think you're going. The optimal route will be figured out by your car. When you arrive at your destination, simply step out at the entrance and your car will enter park seek mode, automatically searching for a spot and parking itself There is a tap on your phone.

The company's vehicles could not at the time of those advertisements, and cannot now, operate without a driver, according to the complaints.

There are two complaints against the manufacturing and dealership divisions of the electric car company.

The company's license to sell cars in the state may be suspended or revoked if it is found guilty of violating the law.

The complaint was signed by the chief of the industry services branch of the Department of Motor Vehicles' occupational licensing division.

In an interview in June, Musk said that self-driving technology is essential to the company's financial success.

Musk said in an interview with the "Tesla Owners Silicon Valley" that the focus was on full self- driving. That's important. It is the difference between being worth a lot of money or not.

Despite customer complaints, the billionaire has been making big promises about self- driving features for years.

At the end of the year, Musk said he was certain that the cars would be able to find you in a parking lot, pick you up, and take you all the way to your destination.

Representatives for the company did not reply immediately.
