Mozilla Foundation dubs Tesla, Nissan, and fellow modern cars a “privacy nightmare”
A report published by the Mozilla Foundation has claimed that cars are the “worst category of products for privacy” that the firm has ever reviewed. As noted by Mozilla, out of 25 car brands that it studied, none made the cut. Tesla, arguably the most software-focused carmaker today, was singled out by the firm for its “untrustworthy AI.”
Mozilla noted that automakers today, if one were to closely look at their privacy policies, collect a lot of data. The firm noted that every single one of the 25 car brands that it studied collected more personal data than necessary. Around 84% of the carmakers also share or sell customer data, and 92% give drivers little to no control over their personal data.
Specifically, Mozilla studied Renault, Dacia, BMW, Subaru, Fiat, Jeep, Chrysler, Dodge, Volkswagen, Toyota, Lexus, Ford, Lincoln, Audi, Mercedes-Benz, Honda, Acura, Kia, Chevrolet, Buick, GMC, Cadillac, Hyundai, Nissan, and Tesla. Among these, Mozilla called out Tesla and Nissan for data privacy policies that are reportedly alarming.
As noted by Mozilla, Tesla is actually not too bad when it comes to its privacy policies. The company, for one, does not sell or rent personal information to third parties. Tesla also gives owners the choice of whether they wish to share their personal information with third parties or not. Mozilla, however, took issue with Tesla’s warning that customers who opt out of vehicle connectivity could have a car that’s unusable.
“If you no longer wish for us to collect vehicle data or any other data from your Tesla vehicle, please contact us to deactivate connectivity. Please note, certain advanced features such as over-the-air updates, remote services, and interactivity with mobile applications, and in-car features such as location search, Internet radio, voice commands, and web browser functionality rely on such connectivity.
-->“If you choose to opt out of vehicle data collection (with the exception of in-car Data Sharing preferences), we will not be able to know or notify you of issues applicable to your vehicle in real time. This may result in your vehicle suffering from reduced functionality, serious damage, or inoperability,” Tesla’s privacy notice read.
Nissan, for its part, is reportedly worse, Mozilla noted. The firm noted that in the Nissan USA privacy notice, the automaker makes references to some strange policies. In the “Types of Personal Data collected” section of the page, for one, Nissan noted that things such as “citizenship status, immigration status, race, national origin, religious or philosophical beliefs, sexual orientation, sexual activity, and genetic information” are collected.
Nissan also noted that the company could share and sell “inferences drawn from any Personal Data collected to create a profile about a consumer reflecting the consumer’s preferences, characteristics, psychological trends, predispositions, behavior, attitudes, intelligence, abilities, and aptitudes” to other parties for targeted marketing purposes.
“Nissan earned its second-to-last spot for collecting some of the creepiest categories of data we have ever seen. It’s worth reading the review in full, but you should know it includes your ‘sexual activity.’ Not to be outdone, Kia also mentions they can collect information about your ‘sex life’ in their privacy policy. Oh, and six car companies say they can collect your ‘genetic information’ or ‘genetic characteristics.’ Yes, reading car privacy policies is a scary endeavor,” the Mozilla Foundation noted.
The Mozilla Foundation noted that Nissan is probably the worst car company that it has reviewed with regards to privacy. However, in the firm’s rankings, it opted to put Tesla at the bottom of the list, below Nissan. This, according to Mozilla, was because Tesla also received marks for having “untrustworthy AI,” which is connected to Autopilot.
“Tesla is only the second product we have ever reviewed to receive all of our privacy ‘dings.’ (The first was an AI chatbot we reviewed earlier this year.) What set them apart was earning the ‘untrustworthy AI’ ding. The brand’s AI-powered Autopilot was reportedly involved in 17 deaths and 736 crashes and is currently the subject of multiple government investigations,” the foundation noted.

Tesla sees sharp November rebound in China as Model Y demand surges
New data from the China Passenger Car Association (CPCA) shows a 9.95% year-on-year increase and a 40.98% jump month-over-month.
Tesla’s sales momentum in China strengthened in November, with wholesale volumes rising to 86,700 units, reversing a slowdown seen in October.
New data from the China Passenger Car Association (CPCA) shows a 9.95% year-on-year increase and a 40.98% jump month-over-month. This was partly driven by tightened delivery windows, targeted marketing, and buyers moving to secure vehicles before changes to national purchase tax incentives take effect.
Tesla’s November rebound coincided with a noticeable spike in Model Y interest across China. Delivery wait times extended multiple times over the month, jumping from an initial 2–5 weeks to estimated handovers in January and February 2026 for most five-seat variants. Only the six-seat Model Y L kept its 4–8 week estimated delivery timeframe.
The company amplified these delivery updates across its Chinese social media channels, urging buyers to lock in orders early to secure 2025 delivery slots and preserve eligibility for current purchase tax incentives, as noted in a CNEV Post report. Tesla also highlighted that new inventory-built Model Y units were available for customers seeking guaranteed handovers before December 31.
This combination of urgency marketing and genuine supply-demand pressure seemed to have helped boost November’s volumes, stabilizing what had been a year marked by several months of year-over-year declines.
-->For the January–November period, Tesla China recorded 754,561 wholesale units, an 8.30% decline compared to the same period last year. The company’s Shanghai Gigafactory continues to operate as both a domestic production base and a major global export hub, building the Model 3 and Model Y for markets across Asia, Europe, and the Middle East, among other territories.
Tesla bear Michael Burry got blunt with his beliefs over the company’s valuation, which he called “ridiculously overvalued” in a newsletter to subscribers this past weekend.
“Tesla’s market capitalization is ridiculously overvalued today and has been for a good long time,” Burry, who was the inspiration for the movie The Big Short, and was portrayed by Christian Bale.
Burry went on to say, “As an aside, the Elon cult was all-in on electric cars until competition showed up, then all-in on autonomous driving until competition showed up, and now is all-in on robots — until competition shows up.”

For a long time, Burry has been skeptical of Tesla, its stock, and its CEO, Elon Musk, even placing a $530 million bet against shares several years ago. Eventually, Burry’s short position extended to other supporters of the company, including ARK Invest.
Tesla has long drawn skepticism from investors and more traditional analysts, who believe its valuation is overblown. However, the company is not traded as a traditional stock, something that other Wall Street firms have recognized.
While many believe the company has some serious pull as an automaker, an identity that helped it reach the valuation it has, Tesla has more than transformed into a robotics, AI, and self-driving play, pulling itself into the realm of some of the most recognizable stocks in tech.
Burry’s Scion Asset Management has put its money where its mouth is against Tesla stock on several occasions, but the firm has not yielded positive results, as shares have increased in value since 2020 by over 115 percent. The firm closed in May.
In 2020, it launched its short position, but by October 2021, it had ditched that position.
Tesla has had a tumultuous year on Wall Street, dipping significantly to around the $220 mark at one point. However, it rebounded significantly in September, climbing back up to the $400 region, as it currently trades at around $430.
It closed at $430.14 on Monday.
Tesla appears to be making a change to its exterior side repeater cameras, which are used for the company’s Full Self-Driving suite, and other features, like Sentry Mode.
The change appears to be a potential upgrade in preparation for the AI5 suite, which CEO Elon Musk said will be present on a handful of vehicles next year, but will not be widely implemented until 2027.
Currently, Tesla uses a Sony sensor lens with the model number IMX963, a 5-megapixel camera with better dynamic range and low-light performance over the past iteration in Hardware 3 vehicles. Cameras in HW3 cars were only 1.2 megapixels.
However, Tesla is looking to upgrade, it appears, as Tesla hacker greentheonly has spotted a new sensor model in its firmware code, with the model number IMX00N being explicitly mentioned:
Looks like Tesla is changing (upgrading?) cameras in (some?) new cars produced.
Where as HW4 to date used exterior cameras with IMX963, now they (might potentially) have something called IMX00N— green (@greentheonly) December 1, 2025
Sony has not announced any formal specifications for the IMX00N model, and although IMX963 has been used in AI4/HW4 vehicles, it only makes sense that Tesla would prepare to upgrade these external cameras once again in preparation for what it believes to be the second hardware iteration capable of fully autonomous self-driving.
Tesla has maintained that AI4/HW4 vehicles are capable of self-driving operation, but AI5 will likely help the company make significant strides, especially in terms of overall performance and data collection.
Tesla last updated its exterior cameras on its vehicles back in early 2023, as it transitioned to the 5-megapixel IMX963. It also added additional cameras to its vehicles in January with the new Model Y, which featured an additional lens on the front bumper to help with Full Self-Driving.
