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.

Lemonade has expanded its innovative Autonomous Car insurance program to Tennessee, giving Tesla owners in the state a substantial discount on Full Self-Driving (FSD) miles. Announced on August 3, the product offers 50 percent off every mile driven with FSD activated, positioning the digital insurer as a leader in pricing insurance around autonomous technology.
The program, marketed as Lemonade Autonomous Car insurance, uses a direct connection via Tesla’s Fleet API (with customer permission) to automatically distinguish FSD-engaged miles from manual driving. Policyholders pay a low base rate when the vehicle is stationary and a few cents per mile when moving, with the 50 percent reduction applied specifically to FSD miles.

Coverage includes standard protections such as liability, collision, comprehensive, roadside assistance, and Tesla-specific benefits like access to certified repair shops and emergency crash services. Eligible vehicles require Hardware 4, as well as recent firmware.
Lemonade first unveiled the product on January 21 of this year, describing it as a first-of-its-kind offering designed for self-driving cars, starting with Tesla FSD. It began rolling out in Arizona on January 26, followed by Oregon about a month later. Subsequent expansions brought it to Indiana in early June 2026 and Colorado later that month.
Tennessee marks the fifth state.

Tesla Full Self-Driving gets outrageous insurance offer with insanely cheap rates
The discount rests on Lemonade’s strong belief in the safety of Tesla’s FSD system. The company cites Tesla’s data showing that FSD-driven miles are twice as safe as those driven manually, or associated with roughly a 50 percent crash reduction.
Lemonade Co-founder and President Shai Wininger has emphasized this distinction: “Traditional insurers treat a Tesla like any other car, and AI like any other driver. But a car that sees 360 degrees, never gets drowsy, and reacts in milliseconds can’t be compared to a human.”
He added that “Teslas driven with FSD are involved in far fewer accidents” and committed that as FSD software improves and becomes safer, Lemonade’s prices will drop further.
Tesla Full Self-Driving gets an offer to be insured for ‘almost free’
This approach leverages Lemonade’s existing pay-per-mile technology and AI-driven risk models, which analyze nuanced vehicle data including software version and sensor performance. The company expects the model to reward higher FSD usage with greater savings while supporting mixed households that include both Tesla and non-Tesla vehicles under one policy. Bundling with home, renters, or pet insurance can yield additional discounts.
As autonomous driving technology advances, Lemonade’s state-by-state expansion of usage-based pricing that directly reflects real-world safety data represents a notable shift in how insurers evaluate risk.

Tesla owners in the five available states – Arizona, Oregon, Indiana, Colorado, and now Tennessee – can obtain quotes quickly through the Lemonade app or website, potentially lowering the overall cost of ownership for vehicles equipped with advanced driver-assistance systems. Further states are expected as regulatory approvals progress.
Tesla has continued to flex the strength, rigidity, and robustness of its all-electric pickup, the Cybertruck. In fact, since 2019, Cybertruck’s ability to avoid dents, dings, and even gunfire has been one of the main selling points Tesla has used to attract buyers who are looking for a vehicle that can handle the most intense challenges.
But that does not mean Tesla is not still actively trying to make it even better.
In a new hardware update, Tesla has decided to change the material of the Cybertruck’s underbody panels from aluminum to carbon fiber, a move that aims to not only increase pricing efficiency but also improve strength.
RELATED:
Cybertruck Lead Engineer Wes Morrill confirmed the change was made to the Cybertruck recently after it was spotted by Coleton Guerin of Out of Spec. This particular trim level was a Cyberbeast, but it is being applied to all trims to keep supply chain efficiency high and have less variance across trim levels.
Morrill said that Tesla tested different materials for the underbody panel protection, and carbon fiber performed better than aluminum, which is what the company was using since its first deliveries in 2023.
-
Additionally, there are some efficiency improvements because Tesla can better form the areas around the bolts to keep underbody airflow cleaner than previously.
good eye – it’s a new material. Testing showed it to be more durable than the aluminum while being lower weight and cost. Also slight efficiency improvement since we can better form the areas around the bolts to keep the underbody airflow cleaner than what stamped aluminum allows
— Wes (@wmorrill3) July 30, 2026
Carbon fiber is traditionally lighter and more durable than aluminum, which is why it is such a popular material among luxury automakers, and EV makers will utilize some of the materials around battery packs to save weight.
This is the first instance of Tesla utilizing carbon fiber on the Cybertruck’s exterior to help with overall performance and strength. As previously mentioned, Tesla used aluminum to protect the underside of the body, but it is pretty typical for the company to continue making engineering changes that will improve the car in the future.
Tesla released Full Self-Driving version 14.3.7 yesterday, and after about 90 miles of testing today, it is evident there are some definite fixes from version 14.3.6, which I wrote about last week and called a regression.
Within the first 40 minutes of my drive on v14.3.7, it saved me from getting into an accident with an unaware Dodge Charger driver, and some of the things Tesla seemed to miss in v14.3.6 were definitely improved. All in all, the release so far has some really great performance, and I’m looking forward to testing it further.
For now, here’s everything I noticed with v14.3.7:
Overall Improvement
Just generally speaking from a ride perspective, this was a really great experience. A lot of the hesitancy I experienced on v14.3.6 was gone. There were no instances of brake-stabbing, wheel-jerking, or any uncertain or unconfident movements. It was void of anything that I felt made it timid with v14.3.6.
The one thing I do hope to see down the road is a smaller need to adjust Speed Profiles so often. Because Tesla calls FSD “Supervised,” I’m okay with needing to hit the scroll wheel a few times a drive.
However, I hope that things can be incrementally improved upon with speed. Sometimes it’s too fast; other times it’s too slow. It’s a difficult thing to hone in and refine, but I hope it eventually gets there.
I didn’t notice any significant left lane camping or any behaviors that were completely out of line. I am hopeful that this opinion does not change, but after driving a few days with this version and putting it in a variety of different situations, you are exposed to more behaviors, some of which are not necessarily what I’d prefer.
-
The big things to notice, at least in my experience thus far, are that the major issues with previous versions — meaning the braking stabbing and wheel jerking — simply weren’t there. That’s enough to already consider this progress compared to .6.
Manual Signal Override is More Responsive
On .6, I had quite a few issues with FSD ignoring my manually input turn signals. If Tesla wants to call it “Supervised,” then the car should not ignore any input the driver gives. If I touch the accelerator on FSD, the car speeds up.

The car did a great job of obeying my turn signals when I wanted it to change lanes, which is welcome.
Parking Lot Performance
Before .6, I traditionally took over in nearly every parking lot my car entered, because I knew it would not park somewhere that I wanted, and usually, it was just a tad too timid in this setting.
The one bright spot of .6 was how well it handled parking lots. This continued with v14.3.7:
-
I’m always really happy to see progress at all, but once parking preferences come to FSD, as long as this performance is still around, that could potentially be the biggest improvement I’ve seen in FSD in the year I’ve been using it personally on a daily basis.
Full Self-Driving Averts Disaster
A Dodge Charger changed into my lane without checking if I was there, running me off the road. FSD made the initial avoidance maneuver; I grabbed the wheel out of instinct, looked in my side mirror to ensure I had nobody following closely behind, hit the brake, and straightened the car back up to avoid a curb:
🚨 Guys this is why you all NEED to stay vigilant behind the wheel, even on Tesla Full Self-Driving
Human drivers are UNHINGED and have no idea what they’re doing anymore. This was a kid obviously younger than 20 years old with zero awareness.

There have been quite a few responses to this video stating that I should never have grabbed the wheel. To be honest, I really wish I had not done so, because I do believe FSD would have avoided any sort of collision with anything, including the car or the curb.
However, this was the first time I had ever been this close to being hit while using FSD. My natural reaction was to take over. I think if I had had something like this happen before, my reaction might have been different.
Hitting the brake avoided hitting the curb, while FSD swerved to avoid the car. My concern after the car was clear of my front end was the curb. All in all, I’m really happy with how things turned out, and I think anyone could be a critic of how I handled it. I only had a split second to really make a decision, and thankfully, any damage was avoided.
It is clear FSD managed to avoid the car coming down before I was able to. I truly credit FSD for avoiding the collision.
What Needs to Improve
Better Recognition of Potholes, Uneven Roads, Sharp Changes in Roadway/Bumps
On Friday, my Fianceè and I were in the car, and FSD was driving us. We crossed over a roadway that has a traffic light, and FSD was traveling at 40 MPH on Standard, 5 MPH over the speed limit. Everything was more than reasonable.
However, the road we were crossing at the light has a major bump both as you start and finish crossing it. Without a speed reduction, your car can go airborne. The Tesla did just this on Friday on v14.3.6; it was an uncomfortable bounce that pretty much confirmed I would not ever let FSD go over again unless we were sitting at that intersection when there is a red light.
I even tried scrolling down into Sloth quickly, but I ended up just taking over:
-
This is that big bounce that I mentioned in the quoted post.
It’s just a tad too drastic to take at the speed FSD wants to go over it. You can see me quickly swipe down into Sloth, but I intervened. https://t.co/K20PK9ysBg pic.twitter.com/81Oc82ZJcZ

A few people have said it remains related to the vision-based approach and its difficulty comprehending 3D. This is a huge issue because this can cause serious damage at certain speeds.
Navigation
Nothing new here. I still turn off “Online Routing” quite frequently to get the car to take logical routes from time to time.
Auto Wipers
Auto Wipers are just plain bad. I really hope Tesla just uses a rain sensor. I thought they had improved at one point, but I still get dry wipes, Speed 4 on a drizzle, and Speed 2 on a steady rain. In reality, these should be switched.
