Tesla makes its cars lie about their mileage, lawsuit claims

But Musk isn't programming this 'cheat' in himself, some programmer was told to do this by management and that individual didn't have enough of an issue with it to say no, and so they did it.
Which means your fellow man/woman (but who's kidding who, it's likely a man), one of the ones that say "I'm a programmer at Tesla", is responsible for cheating the common, faceless, consumer. That, to me, is the shittiest part..

If VW could hide their emission cheating program for years I don't see why Tesla wouldn't be able hide an odometer cheating program. It wouldn't be that hard to detect normal driving habits and implement the odometer cheating only then.
Tesla's own data-collection should serve nicely. They likely have both odometer and GPS logs for every car they have ever sold.

I despise Musk, and hope to see him in jail. I'm no Tesla fan, and will never buy one of their vehicles. That said? This accusation seems unlikely to me, especially when it is backed only with "these numbers seem different from what I had in the past with different cars".
Did you read the whole article? Because it isn’t just “different numbers from different cars”.

If there was some direct empirical evidence, such as "We put a Tesla on a measured 10 mile track and drove the track 100 times, and it added 11160 miles to the odomoeter, whereas when we did the exact same test with a Hyundai Ionic, it added 10002 miles.", I could easily believe it. While somewhat costly, such an experiment is easily doable.
Why would someone do that to their own personal vehicle? If the car gives one mileage at one point in time and then seemingly gives a different distance at a different point in time over the same route… that would be odd, to say the least.

So easily doable, in fact, that it would greatly surprise me if Tesla actually did this.
For someone who describes themself as “no Tesla fan”, you’re carrying a lot of water for them.

Companies absolutely commit fraud all the time, but in order to do this, Tesla would have left a blazing red trail of evidence in the code a mile wide. It would be simply impossible to hide, both via the aforementioned easy-to-perform empirical test and via an analysis of the codebase that drives the odometer.
Yeah… but the code isn’t out there for anyone to review. If the code is flawed, then it will come out during discovery, if the trial goes that far.

Plus, the savings? Pretty minimal, especially when compared to the exposure.
People/companies cut corners all the time for cost savings. And considering how it certainly seems that Teslas have a decent amount of problems… not having to fix those problems on their own dime can add up fast.

If they DID do this? It would sink Tesla. It would cost them billions of dollars.
Doubtful. I’m willing to bet that the damages would be capped at some amount per incident. And theoretically, Tesla could settle to avoid crazy damages and admitting liability.

They know this. And with a strong likelihood of being found out? Why would any manager with sufficient authority to do this approve it to save a few tens of millions at most. This would only shave off a relatively small portion of warranty claims, and would do nothing to save any recall costs.
Maybe Musk was the one who demanded this. After all, less money that Tesla has to spend, the better they look on their quarterly and yearly earnings reports, therefore increasing his wealth.

Is this possible? Sure. But it is an extraordinary claim, and before I would believe this, I would have to see MUCH more evidence than what is mentioned in this lawsuit.
That’s what a trial is for.

I dislike Musk as much as the next person, but this seems pretty ludicrous and backed by nothing more than "I have a feeling", and people describing their average daily commute. Mileage can easily rack up on trips that are outside of our norm that we easily forget.
Who knew that one’s daily commute would be considered “trips that are outside of [one’s] norm…”? :rolleyes:

Talk about a random nonsequitor. Why Trump isn't locked up in Georgia right now has nothing to do with pardons.

It has everything to do with the prosecutor fucking up the biggest and most important case that the state of Georgia may ever have come through its courts.
A case about the material application of state law is hardly random in a discussion about how state law will save us any day now. A system is what a system does, not what it claims to be.

Have to update the list for people who only recently decided Tesla was bad.

"I only supported Tesla when they were:
  • lying about FSD capabilities putting the public at risk
  • firing anyone wanting to unionize
  • promoting a hostile workplace
  • taking billions from china
  • fake greenwashing projects
  • cooking the books
  • designed cars that get totaled in a fender bender
- falsifying odometers to screw their customers

But I don't any more."
don't forget that they were/are openly racist to their employees in their factories

I don't believe that GPS is the primary "sensor" here. Otherwise you wouldn't be able to get speed or miles tracked while, say... in a tunnel. I think it would've been widely reported if driving into a tunnel suddenly made your speed go to 0 (or get stuck on whatever the last speed reading was while slowing).
Are you telling us there are downsides when everything's computer?!

This is something that could be tested very easily by someone else with a sub-50k mile Tesla (quick, before they do an OTA update to hide their tracks). Pick out a 50-mile route and drive the Tesla and two normal cars down it, then read the change in the odometer. This would be much more compelling evidence of fraud.
cough Sounds like a job for an automotive journalist. cough

To be clear, I'm not defending Tesla here, but going through the effort to insert an algorithm to inflate odometer readings predictively versus taking readings off a sensor and simply doing the conversion to miles feels like a lot of extra work for something that ought to be fairly easy to expose. It could be that they're doing something even more convoluted OTA and going to great lengths to hide it and only do so on some cars? I think I'd like to see data before I don my tin foil hat. Then again they did make it play farts and has a "rainbow road" easter egg so god only knows what Tesla developers are doing with their time.

This got me curious, so I checked where my Model Y is at. I had my tires replaced on July 19, 2024 and my mileage was at 55,312 as recorded on the invoice. According to my car I'm currently at 78,151, so that's 22,839 in 9 months.

Work is 45 mi roundtrip. Assuming an average of 22 workdays per month x 9 months, that's 8,910 for my work commute during that time, leaving 13,929 for recreational use. It's hard to say for certain because I don't track personal driving, but that seems like a lot.

It's also why Tesla engineers make such good sycophants for Musk dragging them along with him to his other debacles like X or DOGE, because they're already conditioned to "just following orders" at best and are guzzling his kool-aid at worst

They were probably at least semi smart about it. Like VW did it probably tries to detect patterns indicating it's on a dynamo and then doesn't lie assuming it's being tested, which means the real testing can only be done in real world conditions which massively increases the calendar time window to do the study using typical driving

Makes you wonder how Tesla vehicles measure speed since the speedometer and odometer usually use the same sensor or mechanical takeoff from the axle or drive shaft.

ABS wheel sensors like every other car. But that doesn't preclude them doing something shady.

But I note this guy seems to be going largely based on his assumptions of monthly mileage.

You could just run an independent GPS and check this.

IMO, If it was that far off, many would have noticed something before now. I'd bet a lot of testers use GPS in their testing.

If you have a Tesla check it...

True, and I think mechanics have equipment designed to do just that.
It can be much more simple than that. Next time you are driving a nice, straight-ish piece of interstate highway, note the mile markers on the side of the road as you cruise along. Over a distance of 10 miles or so, they are usually quite accurate. It's easy to see if your odometer is within a few percent of correct.

seems like it'd be easy to add an external sensor to compare the odometer to how much the wheels actually spin
I like how none of the Ars commenters question this happening but dive right into how, as well as expressing overall doubt that anything will come of it.

When I was switching away from my prior Tesla Model S, I decided to lease a different EV. I figured that I was only using about 12k miles per year, as that's about how much I usually drive. Even back with my earlier Model 3, I was logging all of my trips using TeslaFi, so when I checked my odometer history on TeslaFi, I was shocked to see that I had actually used around 17k-18k in the first year. This article makes me curious to do a deeper dive on the numbers.

You don't even need a dyno, you just need a fifth wheel. They've been a standard part of the automotive testing landscape for forever. Not used so much now due to GPS but they're simple and would be very difficult to cheat. I guess it'd be technically possible to use the car's cameras to detect if there's something hanging off of it but that's getting pretty damn convoluted.

actually wondering if the power to pardon applies to legal entities now. can you just pardon Tesla fur any past and future crimes? (not that pesky things as "the law" will stop fascists)
I think the president can pardon corps for federal crimes. But only past crimes not future crimes. And they cant pardon them from lawsuits.

Yes, because odometer tampering and fraud are both state level crimes.
I'm sure lots of DA's in the remaining Free States would jump on this. But the plaintiff needs more evidence before bringing it.
  1. Disconnect the cellular modem so Musk can't tamper with the car remotely.
  2. Using something like Waze, plan a trip of something like 100 miles.
  3. Take a photo of the odometer before starting the trip.
  4. Make the trip with Waze on.
  5. Take a photo of the odometer afterwards. Any significant variation is your proof.
  6. Take all of this to the DA and offer to demonstrate it. And with that, you have Diesel Gate.

My point was more over the driving patterns than the mechanism of measure. My suspicion is that the tesla software will try to detect what looks like a test on a dynamo rig, aka driving at constant speed in a straight line for a prolonged amount of time, and stop fudging the numbers in that scenario just like VW kicked in their hidden special emissions trap in those cases.

A track course is less certain but my point was more that testing will likely need to be wheels on pavement with a driver as your picture shows vs a test done on a test stand

Is this relatively recent? Or an EV thing? I'm most familiar with 'golden age' Hondas that use a sensor in the distributor for RPM and a gear on the differential for distance.
I think we're saying the same thing:

distance = measured using gear (or electromechanical sensor) on the differential (or drive shaft or axle Edit: or wheel).
speed (mph/kph; not rpm) = first derivative of the distance with respect to time.

Can an Elon-owned company commit crimes?

That comment aside, I am actually curious about the comment in the article about arbitration. If a company is committing fraud (allegedly), I have to go through arbitration? Does that sit right with anyone? Well, anyone not on the board at Telsa, at least?

Uh, this is America. The President can't commit crimes.
I wish I could call you a liar for saying this.
GPS. Your phone ccan count mileage easy
I hope unaltered gps logs can be pulled from the car. My car has a trip record.
That plus records from a personal device should be enough to prove what is happening (I know it's an invasion of privacy but I can use google maps to pull trip data and it even knows if I am walking).
But you can compare the logs to independent data. If you drive from point A to B you can look at how far Tesla's log says you drove vs how far google maps says the same route is. He's mostly talking about his commute so that's a lot of trips where you can't fudge what point A and B are. Does the recorded milage vary unreasonably from day to day on his commute? Is there really a change is the relative performance once it's out of warranty, like sub 50,000 miles the logs says the distances are 20% higher than your reference but over 50,000 miles the logs say the distances are 10% shorter than your reference. Tampering with large datasets with lots of connected variables in ways that don't cause findable discrepancies is very difficult.
If Tesla is manipulating customer data I hope they get in a lot of trouble.

The evidence presented in the article is rather weak. He needs to have somebody do some testing on a measured path. I realize it's too late for him to do this with his car, since it's no longer under warranty.

I'm not saying it's not true, just that I think a good lawyer could argue this is not compelling.
Do you not know how trials work?

At this point, just as likely that it is one person trying to game the anti Tesla vibes and get an extended warranty on a car he drove the crap out of after buying it.
I see what you're getting at but what would be the point of such an individual trying to form a class action with other owners when as the article states that will likely be an uphill battle?
