Since Tesla delivered the first units of its all-electric Semi to Frito-Lay facilities in Modesto, California, in December 2022, any instance of one breaking down on the side of the road has been photographed and highly publicized. However, Teslarati has been told that at least some of the “breakdowns” are caused by a glitch within a software switch, and drivers are pulling over voluntarily as a precaution because the dash screens will flicker and sometimes shut off.
Since December, there have been at least eight instances of Tesla Semi vehicles breaking down. Some attributed it to a loss of range from carrying a load of products, as weight and hauling affect how far an EV can go.
Others suspected it was a mechanical issue, as the Semi is still a relatively young product that has been in development for some time but has only been used in real-world applications by a company that is not Tesla for a few months.
Tesla Semi developers reflect on first deliveries: ‘Out the door. For the world.’
While these are a possibility, they would be expected. Vehicles break down all the time for various reasons, including mechanical failures, and people often run out of gas in combustion engine vehicles and/or range in EVs.
Tesla Semi drivers are experiencing dash issues
At least some of the Semi breakdowns can be attributed to a glitch with a software switch, Teslarati has learned. How many of the breakdowns can be attributed to this issue is unknown, but more than one has been described as having this problem.
According to a source close to the operation in Modesto, drivers are pulling over their Semis as a precaution, as the glitch is causing the dash screens and lights on those screens to flicker and sometimes shut off. “They don’t know what to do,” said the person who did not want to be identified. “So they just pull over, and then they are towed.”
Drivers and others involved in the logistics portion of the operation at Frito-Lay that use the Tesla Semi have stated that the screens will not operate properly. Drivers are pulling over as the screens hold valuable information, such as speed, range, camera views surrounding the truck, suspension information, trailer hitch controls, and more.

Without the screens being operational, drivers run into issues that can affect how their jobs are performed, including important safety metrics like speed.
The vehicles are then towed to what we were told is a “secret location” in Lathrop, California, for inspection and repair.
A tow truck driver that has been responsible for transporting the Semis to Lathrop said they had towed at least four units to that location thus far.
Why This Isn’t So Bad
The Semi has only been in Frito-Lay’s hands for about four months, and it is an extremely early project that is still a very limited operation. Frito-Lay expects to have only fifteen Tesla Semis in Modesto this year, so the vehicle is not taking over the entire fleet. In fact, Frito-Lay has adopted various sustainable technologies from several companies to make the Modesto plant more environmentally friendly.
The issues, if completely software-related, can be fixed by Tesla engineers. While the Semi is much different than its passenger vehicles, Tesla has a reputation for having some of the best software in the EV industry. There would likely be much more concern if these breakdowns could be attributed to a part failure or range depletion.
Tesla already displayed the Semi’s capabilities with a full load during the unveiling event in December, showing the all-electric class 8 truck traveling 500 miles on a single charge. We were not told about or made aware of any hardware failures or breakdowns that were caused by parts failures.

The problems with the Semi are likely expected by both Tesla and Frito-Lay as it is still an early-stage vehicle that is being rolled out in a very limited fashion.
Frito-Lay/PepsiCo. did not immediately respond to our request for comment.
What’s Next
Tesla is still moving forward with its plans to expand Semi production in Nevada, as earlier this year, it announced it would build a $3.5 billion expansion to Giga Nevada.
As for Frito-Lay and PepsiCo’s facility in Modesto, there is no indication that they will let a few early issues with the Semi ruin their fleet. In fact, the facility is set to have Megachargers installed at its plant in Fresno, California.
As far as we know, the Semi is still operating daily. Yesterday, it was spotted in Sacramento.
The big picture is that vehicles break down, and new vehicles sometimes have issues that need to be ironed out. It doesn’t mean the project is a failure or that the Semi is doomed to be a dud. It’s the growing pains of the Semi operation.

Tesla V2L adapter for Model Y stirs up a new complaint among owners
On Friday, Tesla launched the Outlet Adapter that enabled Vehicle-to-Load (V2L) energy transfer, meaning owners could essentially utilize their cars as a power source for things like laptops, electric grills, or string lights.
However, even owners of some of the newest builds of the Model Y are finding out that their cars are not compatible with the new $80 accessory, stirring up a new complaint among members of the community.
Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.
Upon the release of the Outlet Adapter on Friday, I signed into my Tesla account to order the accessory. However, I was met with the dreaded “This product is not compatible with your 2026 Model Y” message at the bottom of the screen.
Some said their accounts also displayed the same message, but they ordered anyway. However, they might be surprised to find that this is no mistake; some of the newest Model Ys do not have the appropriate Power Conversion System (PCS). Mine, which was ordered on this day last year and delivered on August 31, has the old 48A, single-phase PCS.
Vehicles with the new, two-piece PCS are able to utilize V2L features on their cars:
🚨 Looks like you can hit the Parts Catalog and enter your VIN and check to see if your Model Y will be able to use the adapter for V2L.https://t.co/QA9zRk7n2k
h/t to @SawyerMerritt for finding this out.
I am sad but this isn’t a huge loss. https://t.co/AYpI12QVV9 pic.twitter.com/LRFSrtRywo

Obviously, it’s disappointing. Many owners have taken delivery this year and still can not utilize the Outlet Adapter because their cars feature the old PCS:

It looks like if you have one of these older PCS units, you can upgrade, but the parts alone are $1,750, and that’s before Tesla adds labor for installing. It is honestly more logical to get some kind of portable power supply or power station at that point.
It is great that Tesla has enabled V2L for Model Y vehicles, but it is also unfortunate that vehicles that are less than one year old are not able to take advantage of this awesome new feature.
With that being said, it truly is a first-world problem; can you really complain when Full Self-Driving is available, maintenance is incredibly inexpensive, and the car has been so good through a year of ownership?

Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.
Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.
It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.
If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.
🚨 Tesla has launched the Outlet Adapter for Model Y Premium in the U.S., enabling V2L capability for all Premium trims (that’s what it appears to be as it is available for purchase with all Premium trims)
It’s available for $80. 2.4kW max power and rated for 120v, 20A pic.twitter.com/lDxlVIk5s8
— TESLARATI (@Teslarati) August 14, 2026
For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?
They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.
Tesla launched the Outlet Adapter in China last year:
Tesla China rolls out Model Y L V2L adapter, and it’s free for early owners
You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.
It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.
You can buy it here from Tesla for $80.

Tesla Roadster unveiling nears, and it will fly: The Information
Tesla is nearing its long-awaited unveiling of the all-electric Tesla Roadster, a new report from The Information claims, as the company has said several times this year that the event would take place “soon.”
Now, it appears there is movement on Tesla’s end regarding when it will happen.
The report says that Tesla will unveil the Roadster as soon as this month with a SpaceX version that will utilize cold-gas thrusters to help the vehicle float for a short period of time. This is something CEO Elon Musk has talked about with the Roadster for years.
🚨 The Information is reporting this morning that Tesla is ready to unveil the “flying” Roadster as soon as this month
It’s almost here, folks. pic.twitter.com/IdL4atsucQ
— TESLARATI (@Teslarati) August 14, 2026
Additionally, due to the delays, Tesla explored “a variety of designs” for the Roadster, potentially planning to abandon the design it showed off for the first time in 2017 and adopting an entirely new aesthetic.
According to The Information, Tesla considered utilizing a repurposed Model S Plaid and even wanted to upgrade the look to something like a Lamborghini Countach.
We’ve heard all of these things before, including teases about the date and how “soon” the Roadster will finally be ready to be shown off to the world (for the second time). Musk said that the event would occur in April, then May, then Chief Designer Franz von Holzhausen continued to say it would be coming “soon.”
We do expect to see the Roadster by the end of the year, and now with this new report swirling, it appears it could be sooner rather than later.
The wait has been incredibly long, but there is likely a good reason for it. Tesla’s desire to make the Roadster the craziest vehicle on the road was non-negotiable, and it likely took a lot of time and resources to develop and perfect into something that was safe and suitable for a vehicle like this.
