Tesla’s Biggest Market Just Threatened to Shut Down Sales Over False Ads

The States Biggest EV Maker Got Caught

Tesla just got an ultimatum from the state where it sells more cars than anywhere else in America. For a company that controls more than half the state’s electric vehicle market, that’s not a slap on the wrist.

A California judge ruled that the company has been misleading drivers for years by calling its driver assistance systems Autopilot and Full Self-Driving, when neither feature actually lets the car drive itself.

Now Tesla has until mid-March 2026 to fix its marketing language or lose the right to sell vehicles in California for 30 days.

And the timing couldn’t be worse, because Elon Musk is betting Tesla’s entire future on the idea that his cars will soon drive themselves.

Judge Rules the Names Are Deceptive

Administrative Law Judge Juliet Cox didn’t mince words after a five-day hearing in Oakland in July 2025.

She found that Tesla had engaged in deceptive marketing for years by using terms that made consumers believe their cars could operate without human attention.

The phrase Full Self-Driving was called “actually, unambiguously false and counterfactual” in the ruling.

Cox originally recommended suspending both Tesla’s dealer and manufacturing licenses for 30 days, but the DMV softened the penalty to give the company time to comply.

This Lawsuit Started Back in 2022

The California DMV didn’t wake up one morning and decide to go after Tesla.

The agency filed formal accusations of false advertising in July 2022 after years of watching the company market features that didn’t match what the technology could actually do.

An amended complaint came in 2023, and the case wound through administrative courts for two more years before reaching Judge Cox’s courtroom.

The state’s argument was simple: Tesla was telling the DMV one thing and telling customers something very different.

Four Phrases Got Tesla in Trouble

State officials zeroed in on specific language from Tesla’s website.

The company advertised that its system was “designed to be able to conduct short and long-distance trips with no action required by the person in the driver’s seat.”

Another claim promised that a Tesla could drive you to your destination, navigate streets and freeways, and then park itself.

California Attorney General Rob Bonta wrote that these phrases “represent specifically that respondent’s vehicles will operate as autonomous vehicles, which they could not and cannot do.”

Level 2 Means You Still Drive

Here’s the thing Tesla doesn’t advertise loudly: its Autopilot and Full Self-Driving systems are classified as Level 2 by the Society of Automotive Engineers, the industry standard.

Level 2 means the car can help with steering and speed, but the human driver must stay alert and ready to take over at any moment.

True self-driving starts at Level 3, where the car handles everything in certain conditions. Level 5 is full autonomy with no steering wheel needed.

Tesla isn’t there yet, and the judge ruled that reasonable consumers didn’t know that.

At Least 65 Deaths Linked to Autopilot

The marketing language isn’t just a branding problem.

Federal data tracked by safety researchers shows at least 65 fatalities connected to Tesla’s Autopilot system through late 2025, including two involving Full Self-Driving.

The National Highway Traffic Safety Administration found that Autopilot had a “critical safety gap” linked to at least 467 collisions.

Investigators pointed to a “weak driver engagement system” that let drivers get distracted while the software was active.

Some fatal crashes involved drivers who were watching movies or looking at their phones.

California Is Where Tesla Makes Its Money

Losing sales in California for even 30 days would hurt. The state accounts for about 35% of all EV sales in America, and Tesla still holds roughly 52% of that market.

The Model Y was the best-selling vehicle in California in 2024, outselling the Toyota RAV4 by nearly two to one. But there’s trouble underneath those numbers.

Tesla’s California sales have dropped for seven consecutive quarters, falling 18% in the first half of 2025 while competitors like Honda and Toyota posted gains.

A sales ban would accelerate a slide that’s already underway.

Tesla Says Nobody Actually Complained

The company isn’t backing down.

A spokesperson dismissed the ruling as “a consumer protection order about the use of the term Autopilot in a case where not one single customer came forward to say there’s a problem.”

The DMV didn’t cite consumer complaints when it filed the lawsuit.

But Tesla is also facing a separate class action suit from drivers who say they were misled about what their cars could do. The judge’s ruling that Tesla lied about Full Self-Driving could become ammunition in that case.

Musk and Newsom Were Already Fighting

This ruling drops into a relationship that was already hostile. Governor Gavin Newsom and Elon Musk have traded insults on social media for more than a year.

In July 2024, Musk announced he would move SpaceX and X headquarters out of California after Newsom signed a law protecting transgender students.

Newsom’s press office responded to one Musk post by writing, “We’re sorry your daughter hates you, Elon.” Musk fired back by misgendering his transgender daughter.

The two have also clashed over deepfake laws and AI regulation.

Tesla Already Changed One Name Quietly

The company hasn’t ignored the lawsuit entirely.

After California filed its accusations, Tesla renamed its premium package from Full Self-Driving Capability to Full Self-Driving (Supervised).

That parenthetical addition was supposed to signal that drivers need to pay attention. But regulators say it’s not enough.

The word Autopilot remains, and the judge found it “follows a long but unlawful tradition of intentionally using ambiguity to mislead consumers while maintaining some level of deniability about the intended meaning.”

Robotaxi Plans Make This Fight Critical

Tesla isn’t just defending old marketing language. The company’s entire future strategy depends on autonomous driving.

Musk announced that production of the Cybercab, a dedicated robotaxi with no steering wheel or pedals, will begin in Texas in April 2026.

Tesla is already testing driverless vehicles in Austin without safety drivers. Analysts at Wedbush estimate that autonomous technology could add a trillion dollars to Tesla’s valuation.

But if California won’t let Tesla call its current systems self-driving, getting approval for actual robotaxis becomes much harder.

The Clock Runs Out in Mid-March

Tesla has 90 days from the December 17 ruling to fix its marketing, which means the deadline lands around mid-March 2026. If the company doesn’t make changes that satisfy the DMV, it loses its dealer license for 30 days.

Manufacturing at the Fremont plant can continue, so Tesla could still build cars. It just couldn’t sell them to anyone in California.

The company could also appeal, dragging the fight into state courts. Either way, Tesla will have to decide whether the word Autopilot is worth losing its biggest market over.

The Petersen Automotive Museum at 6060 Wilshire Boulevard explores everything from early automobiles to autonomous vehicles and electric cars.

General admission runs $21 for adults and $13 for children, with the museum open daily from 10 a.m. to 5 p.m. Exhibits have covered Tesla’s impact on the industry and the broader push toward self-driving technology.

If you want to understand where the automotive world is headed and why California regulators care so much about what companies call their features, this is the place to start.
