Three Tesla owners have sued the automaker in a class action lawsuit that was filed on August 2, 2023, after a report from Reuters last week claims the company “exaggerates” its range ratings.
Teslarati examined the complaint, and we are here to give you a breakdown of what the suit says and what the three plaintiffs are suing Tesla for.
The Plaintiffs
Tesla is being sued by James Porter, Bryan Perez, and Dro Esraeili Estepanian, who state in their complaint against the automaker that their action “arises out of Tesla’s false advertising of its electric vehicles’ range, which Tesla grossly overvalued when selling the vehicles to consumers.”
According to the complaint, Porter owns a Model Y Performance and noticed a discrepancy in his vehicle’s range was compared to what it told him:
“After taking delivery of his Tesla vehicle in June 2022, Plaintiff Porter fully charged his vehicle to 100% battery charge and took a 2-hour trip to visit family, approximately 92 miles away. When he arrived at his destination, Plaintiff Porter noticed that the vehicle was left with approximately 40% charge.”
Perez owns a Model 3 Long Range, and the complaint states he had the same issue:
“After receiving his Tesla vehicle, Plaintiff Perez fully charged his vehicle to 100% battery charge and took an approximately 90-mile trip to visit his parents. After returning home from the approximately 180-mile round trip, he noticed that his vehicle showed that it had roughly 10-15% charge remaining.”
Estepanian also has a Model 3 Long Range, and the complaint describes a similar situation:
“Plaintiff Estepanian travels 140 to 150 miles round trip for his daily commute, and he routinely charges his vehicle to 90% battery charge (which equates to approximately 299 miles), per Tesla’s recommendation. Based on a 90% battery charge (and 299-mile starting range), he typically returns from his approximately 150-mile round trip each day and his Tesla vehicle’s screen displays that approximately 100 to 110 miles of range remain, which equates to roughly 33% battery charge remaining. Thus, Plaintiff Estepanian’s electric vehicle consistently loses approximately 189 miles of range during his daily commute—despite only driving approximately 140 to 150 miles round trip each day.”
The Plaintiffs’ Claims
The plaintiffs state that range is a key feature of electric vehicles and is “one of the most important features that consumers generally consider when purchasing an EV, because it correlates to the distance they can travel before needing to recharge the vehicle.”
Throughout the suit, the complaint shows images of Tesla’s website, highlighting range ratings and other “key features,” including top speed and acceleration.
They also include other pieces of evidence that seem to indicate Tesla has exaggerated range estimates.
One part of the complaint states:
“Tesla’s tactics to inflate the range estimates for its vehicles has continued. Recently, South Korean regulators fined Tesla for false advertising the ranges of its vehicles. Specifically, the Korea Fair Trade Commission found that Tesla exaggerated the “driving ranges of its cars on a single charge, their fuel cost-effectiveness compared to gasoline vehicles as well as the performance of its Superchargers.”
They also stated that other car companies to do not exaggerate range ratings, citing Recurrent’s testing of the Ford Mustang Mach-E, Chevrolet Bolt, and Hyundai Kona:
“Other electric vehicle manufacturers do not overestimate the range of their vehicles to the same extent. For example, Recurrent tested the Ford Mustang Mach-E, the Chevrolet Bolt, and the Hyundai Kona—all electric vehicles and direct competitors to Tesla model vehicles—and found their estimated ranges to be more accurate. In fact, the Hyundai Kona generally underestimated the range the vehicle could travel before requiring a recharge.”
Allegations in the Class Action Suit
The plaintiffs seek to represent anyone in California who purchased any Tesla vehicle and hope to solve questions including:
- a. Whether Tesla model vehicles fail to deliver the advertised estimated vehicle range in normal driving conditions;
- b. Whether Tesla exaggerated its advertised estimated vehicle ranges;
- c. Whether Tesla knew that its advertised estimated vehicle ranges were exaggerated and could not be met under normal driving conditions;
- d. When Tesla gained such knowledge;
- e. Whether Tesla designed, manufacture, marketed, advertised, sold, or otherwise placed its model vehicles into the stream of commerce with such knowledge;
- f. Whether Tesla intentionally concealed the fact that its advertised estimated vehicle ranges were exaggerated or otherwise could not be met under normal driving conditions;
- g. Whether Tesla’s conduct to divert complaints from Class Members who voiced concerns over their Tesla model vehicle’s range violated the terms of Tesla’s warranties;
- h. Whether Plaintiffs and Class Members were harmed by the fraud and deceptive practices alleged herein;
- i. Whether Tesla was unjustly enriched by its deceptive practices; and
- j. Whether Plaintiffs and the Class are entitled to equitable or injunctive relief
The case is 3:2023cv03878, Porter et al v. Tesla, Inc., and has been assigned to Judge Laurel Beeler.

Tesla’s two defunct flagship models are getting a big upgrade
Tesla’s two recently-defunct flagship models, the Model S and Model X, are getting a big upgrade, according to the company’s Head of AI, Ashok Elluswamy.
Older Hardware 3 Model S and Model X vehicles have been the last major holdouts in Tesla’s Full Self-Driving v14 Lite rollout, and that wait now appears to be ending.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
At Tesla’s Cybercab launch, AI chief Ashok Elluswamy told Ryan McCaffrey that he thought the S and X build “was supposed to go out last week.” Evidently, Elluswamy expects the suite to be rolled out to those HW3 Model S and Model X very soon:
For my @Tesla friends – and specifically Model S & X owners with HW3 who are waiting on FSD v14 Lite – I spoke to @aelluswamy at the Cybercab launch, & when I asked for an ETA on v14 Lite for S/X owners, he said, “Oh, I thought it was supposed to go out last week.”
So: soon! 🙌
— Ryan McCaffrey (@DMC_Ryan) September 7, 2026
Those cars are not the current Model S and Model X, which already ship with Hardware 4. They are the pre-refresh flagships built around Tesla’s older Autopilot computer, often called HW3 or AI3.
Tesla stopped putting that computer in new vehicles years ago, which is why owners treat these S and X cars as a closed generation. Model 3 and Model Y vehicles on the same computer began receiving v14 Lite in late June 2026 and saw a wider North American expansion in July. South Korea followed as an early international market. The S and X versions of the same software never joined that wave.
v14 Lite is Tesla’s way of squeezing the current v14 driving stack onto hardware that cannot run the full AI 4 model. The company describes the process as distillation: behaviors learned on the newer computer, including reinforcement learning and offline models, are compressed so the older chip and cameras can use them as a guide.
Early descriptions put the distilled network at roughly 15 percent of the original size. The result is still supervised Level 2 driving. Tesla has been clear that HW3 cannot support unsupervised Full Self-Driving or robotaxi operation because of memory and bandwidth limits.
The feature list is what made the wait so frustrating for S and X owners, as plenty of new features are to be shipped with it.
Official notes for the first Lite build, firmware 2026.20.5.1, added parking, unparking, and reversing; arrival options for a parking lot, street, driveway, or curbside; speed profiles that stay available at all times; and start-from-park engagement. Tesla also claimed better handling of merges, forks, pedestrians, traffic lights, and cut-ins, plus fewer false slowdowns and smoother lane centering.
A mid-July follow-on build, 2026.20.6.10, added more of the Hardware 4 interface, including a standalone Self-Driving app and the ability to start a trip from Park without a brake-pedal confirmation.
Elluswamy called that version the one “likely going to wide release.”
That wide release already reached most other HW3 cars in the United States and Canada. International timing still depends on regional validation and regulatory approval. For S and X owners, the remaining work appears to be model-specific validation rather than a new software stack.
There is no official Tesla changelog or build number for those two models yet, only Elluswamy’s offhand timeline. Some HW3 drivers who already have Lite report large gains over v12.6; others have described new indecision or phantom braking. The next test will be whether the same software lands cleanly on the older flagships that have waited the longest.

This tiny Tesla Cybertruck adjustment has big advantages
Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.
Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup
One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.
Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.
Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.
The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.
The side repeater camera was updated – the version on the left is the newer part which uses passive geometry to create airflow disturbance that better keep water off the lens while driving. No cost penalty, just pure vision improvement. pic.twitter.com/wAbXtcL1Jf
— Wes (@wmorrill3) September 8, 2026
The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.
In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.
Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.
The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.
The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.
New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.
A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.
This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.

Tesla is rolling out a new FSD version with a massive safety addition
Tesla is rolling out a new version of its Full Self-Driving suite to some owners that comes with the massive addition of a safety feature.
Tesla is rolling out Automatic Collision Evasion with the 2026.27.6 Software Update, which started rolling out to some vehicles last night. We received the update, along with Full Self-Driving v14.3.9, as well as v14.2 Lite, which has identical release notes as the previous version and seems to have some refinements and improvements in behavior and performance.
🚨 Tesla FSD v14.3.9 is rolling out as well as 2026.27.6 which includes Automatic Collision Evasion
Brand new safety features from a software update. My Tesla gets better everytime I get one of these pic.twitter.com/ctrMiQXWhM
— TESLARATI (@Teslarati) September 8, 2026
However, most of the attention has fallen on the Automatic Collision Evasion feature, which we covered in an article last week.
The function will activate Full Self-Driving to “try to keep your vehicle safe and then continue driving. It can engage in the following situations while you are driving manually:
- Scenario 1: A frontal collision is imminent and braking alone may not avoid it.
- Scenario 2: Your vehicle detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.”
Essentially, FSD will take over when the vehicle determines you are not paying sufficient attention or are heading toward a potential collision. The addition of this feature is incredibly useful as distracted driving is a major issue in today’s world.
Along with the new safety feature is Tesla FSD v14.3.9, which has no additional release notes compared to the previous version, but in my first drives, my first impression is that operation is great, and parking is still sort of a pain point.
Just took a 15-mile round trip to the gym and back
Pretty on par with what FSD is nowadays – really good. Not enough time to see what’s good and what’s bad, but these first rides on any version feel shockingly good. They’re all pretty identical https://t.co/WN1qTg4bhE

Additionally, Tesla v14.2. Lite has arrived. A great review of that is available here:
— Zack (@BLKMDL3) September 9, 2026
The addition of an Automatic Collision Evasion feature is similar to that of other collision avoidance systems that are used by companies like Hyundai, Kia, and Genesis. These programs typically utilize radar and camera sensors to apply emergency brakes autonomously, though evasive steering in a manual driving mode is pioneered primarily by Tesla’s newest addition.
