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.

Elon Musk
Tesla’s mysterious Robovan makes a sneak peek with Optimus in Terafab video
Elon Musk shared a new Terafab video showing Optimus, Robovans, and a stunningly futuristic campus.
Elon Musk posted a new video of Terafab on X Thursday morning, and the most eye-catching details in it were not the building itself, but two products still awaiting production: Optimus and the Robovan.
The concept render, credited to SpaceX, shows Optimus robots working the grounds of the roughly 2.5-mile-long facility planned for the Gibbons Creek site in Grimes County, while a Robovan glides along an elevated roadway cutting through the building itself, sharing the frame with a Tesla Semi and a Cybercab.
Robovan is the boxy, driverless people and cargo mover Musk unveiled alongside Cybercab at Tesla’s “We, Robot” event in October 2024. He pitched it as a way to move up to 20 passengers at once, or handle freight instead, at a target cost he claimed could fall under a dollar a mile, with no steering wheel or pedals, the same layout as Cybercab. Nearly two years later, Robovan still has no confirmed production timeline and has not shown up in any factory footage, which makes Thursday’s render one of the only recent looks at the vehicle in any form.

Optimus has moved further along. Tesla began converting Fremont’s old Model S and Model X assembly line into a Gen 3 Optimus production line earlier this year, and Musk visited the site on July 1 to mark the changeover. A second, larger Optimus plant is under construction at Giga Texas, targeting volume production in summer 2027 and eventual capacity of 10 million units a year. Tesla AI lead Ashok Elluswamy said this month the robot has “big shoes to fill” in replacing the S and X line, while Musk has repeatedly called Optimus the company’s biggest product of any kind, with a long-term price he has pegged between $20,000 and $30,000.

Check out the “Robovan” from @Tesla

“Terafab Texas will be the largest and most valuable building on Earth by far,” Musk wrote alongside the clip. “And it will be stunningly beautiful.”
One quote post summed up the reaction: “Futuristic scene with RoboVan + Cybercab + Tesla Semi + Optimus.”
Beyond the vehicles, the architecture wrapped around them stands out too. The building’s facade is canted at sharp angles, with illuminated horizontal bands running through what appears to be a multi level interior visible from outside. Below the elevated roadway, pedestrians walk along a plaza next to a reflecting pool, and the skyline behind the campus is dotted with angular spires that read more like sculpture than infrastructure, a departure from the strictly utilitarian look of Gigafactory Texas or Starbase.
The timing tracks with what Terafab representative Riley Trennell told Grimes County residents on Wednesday, when he said renderings of the facility would be released “within days.” Musk’s post followed less than 24 hours later, and Texas Governor Greg Abbott’s office sent out its own release Thursday confirming the project. As Teslarati reported this morning, Terafab’s tax abatement agreements with Grimes County are now signed and active, and SpaceX has sent the county its first $10 million payment under that deal. The dollar figure tied to this phase of construction, per Reuters, is $16.8 billion, one of the first hard capital expenditure numbers attached to Terafab since Musk unveiled the joint Tesla-SpaceX-xAI venture in March.Reaction on X ranged from enthusiastic to skeptical. “God Bless Texas! Everything is bigger and better in Texas!” one reply read. Another was more measured: “Terafab in a decade…..”
Whether the finished building matches the render is a separate question from whether Musk wanted people talking about the render itself. Less than a day after posting, the video had already crossed 5.5 million views.

Cybertruck
Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.
-
SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.
Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.
