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.

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 Cybercab production ignites with 60 units spotted at Giga Texas

Designed exclusively for unsupervised Full Self-Driving, the Cybercab promises to deliver safe, affordable, on-demand mobility without human drivers. Early units with temporary controls allow engineers to refine hardware and software in controlled settings before full autonomous fleets hit the roads.

Tesla Cybercab production at Giga Texas seems to have ignited, as 60 units were spotted outside of the production facility on Wednesday, with speculation hinting the all-electric ride-hailing vehicle could be headed to the lineup sooner rather than later.

Interestingly, they were also spotted with steering wheels, which Tesla said the car would be void of.

Giga Texas observer and drone operator Joe Tegtmeyer shared on X a new post that revealed approximately 60 Cybercabs parked in two organized groups in the factory’s outbound lot—the largest concentration observed to date.

Tegtmeyer noted white seats inside several vehicles and clearly visible steering wheels on most. These are not yet the final steering-wheel-free production versions unveiled in 2024, but early units are likely undergoing validation testing for new features and real-world robotaxi operations across the country.

The timing could not be more symbolic. Tesla has consistently affirmed that mass manufacturing of the Cybercab would begin this month.

CEO Elon Musk has reiterated the April 2026 target multiple times, emphasizing that while initial output will be slow, following the classic S-curve of new-vehicle ramps, the Giga Texas line is being prepared to produce hundreds of units per week.

Tesla CEO Elon Musk outlines expectations for Cybercab production

The first Cybercab already rolled off the line in February, but April marks the official shift to volume production of this purpose-built, pedal- and steering-wheel-free autonomous vehicle.

These 60 Cybercabs signal far more than parked prototypes. They represent tangible proof that Tesla is executing on its ambitious robotaxi roadmap.

Designed exclusively for unsupervised Full Self-Driving, the Cybercab promises to deliver safe, affordable, on-demand mobility without human drivers. Early units with temporary controls allow engineers to refine hardware and software in controlled settings before full autonomous fleets hit the roads.

As production scales, Giga Texas, already home to Cybertruck production, will become the epicenter of Tesla’s autonomous revolution, targeting millions of vehicles annually in the years ahead.

For Tesla and its investors, this sighting underscores manufacturing excellence and timeline discipline. It counters skepticism about the company’s ability to deliver on next-generation vehicles amid a competitive autonomous landscape.

Broader implications are profound: lower transportation costs, reduced emissions, and safer roads as robotaxis proliferate. Musk’s vision of a future where Cybercabs operate 24/7, generating revenue for owners and riders alike, is now visibly underway.

With mass production officially ramping in April, today’s images are not just a snapshot of parked vehicles; they are the first frames of a mobility transformation. Tesla is not only meeting its commitments; it is accelerating toward an era where autonomy reshapes daily life. The Cybercab era has begun.

Tesla headlines will have you believe the company is dead to rights in Germany, selling nearly no cars, and stating consumers are more interested in other brands not run by CEO Elon Musk.

However, the latest data from Germany proves this might be a dying narrative.

Tesla delivered a striking performance in Germany’s automotive market in March 2026, with new vehicle registrations more than quadrupling year-over-year, according to official data from the German Federal Motor Transport Authority (KBA).

Newly registered Tesla vehicles jumped 315.1 percent to 9,252 units, marking the company’s strongest March on record in the country and signaling a sharp rebound after earlier challenges in the European market.

The March surge accounted for roughly 72 percent of Tesla’s first-quarter total in Germany. Q1 registrations reached 12,829 vehicles, a 160 percent increase from the same period a year earlier. For context, the implied March 2025 figure was approximately 2,229 units—one of the brand’s weaker months in recent years.

These numbers underscore Tesla’s ability to capitalize on renewed demand in Europe’s largest car market, where the company had faced softening sales throughout much of 2025 amid heightened competition and broader economic pressures.

Germany’s overall new passenger car market also expanded in March, with 294,161 registrations—a 16 percent rise from the prior year. Battery-electric vehicles (BEVs) performed even more robustly, climbing 66.2 percent to 70,663 units and representing about 24 percent of all new car registrations.

Tesla’s 9,252 deliveries captured approximately 13.1 percent of the BEV segment for the month and roughly 3.1 percent of the total new car market, highlighting its continued leadership among pure-play electric brands despite growing competition from both domestic German manufacturers and Chinese entrants like BYD, which saw its own registrations surge 327.1 percent to 3,438 units.

The strong showing comes as Germany’s EV incentives and infrastructure investments continue to support adoption. Tesla’s lineup, anchored by the Model Y and Model 3, appears to have resonated with buyers seeking premium electric options.

Industry observers note that the concentrated March registrations, accounting for the bulk of the quarter, may reflect strategic inventory management, competitive pricing adjustments, or pent-up demand following a slower start to 2026.

This performance provides a much-needed bright spot for Tesla in Europe, where the brand had seen market share erosion in prior periods.

With Q1 2026 registrations up significantly, Tesla has demonstrated resilience in a market that registered 699,404 new passenger cars for the quarter, up 5.2 percent overall. As the year progresses, sustained momentum in Germany could bolster Tesla’s European outlook, particularly if broader BEV growth persists amid evolving policy support and technological advancements.

The March 2026 data from the KBA paints a picture of Tesla’s renewed strength in Germany: a fourfold monthly leap, record quarterly gains, and a solid foothold in an expanding EV segment.

Whether this marks the beginning of a sustained recovery or a seasonal peak remains to be seen, but the numbers affirm Tesla’s enduring appeal in one of the world’s most competitive automotive landscapes.

Elon Musk reveals unfortunate truth of Tesla Full Self-Driving development

In a candid reply to a dramatic video of Tesla’s Full Self-Driving (FSD) system averting disaster, Elon Musk laid bare a harsh reality facing autonomous vehicle technology.

Published

Tesla’s Full Self-Driving suite is one of the most significant technological developments in terms of passenger travel in decades, but it is not all sunshine and rainbows, even with major strides in safety, CEO Elon Musk revealed.

In a candid reply to a dramatic video of Tesla’s Full Self-Driving (FSD) system averting disaster, Elon Musk laid bare a harsh reality facing autonomous vehicle technology.

The clip shows a Model 3 traveling at over 65 mph on a foggy, rain-soaked highway when a pedestrian suddenly steps into traffic.

Full Self-Driving instantly detects the threat and swerves safely, preventing what could have been a fatal collision for both the pedestrian and the driver’s cousin.

Musk’s response was unequivocal:

“Tesla self-driving saves a lot of lives – the statistics are unequivocal. That doesn’t mean it’s perfect, of course.” Even with a projected 10x safety improvement over human drivers, FSD would still prevent roughly 90% of the world’s approximately one million annual auto fatalities. The remaining 10%—roughly 100,000 deaths—would expose Tesla to relentless lawsuits. Meanwhile, the vast majority of lives saved would go unnoticed. “The 90% who are still alive mostly won’t even know that Tesla saved them. Nonetheless, it is the right thing to do.”

This “unfortunate truth,” as Musk implicitly framed it, highlights a fundamental asymmetry in how society perceives safety technology. Human drivers cause the overwhelming majority of crashes through distraction, fatigue, or error.

Yet when FSD errs, the incident becomes headline news and a courtroom target. Prevented tragedies, by contrast, leave no trace.

Survivors simply continue their journeys, unaware of the split-second intervention that kept them alive. The result is a distorted public narrative that amplifies failures while rendering successes invisible.

We have seen this through various headlines throughout the years, including the mainstream media’s obsession with only mentioning the manufacturer’s name in the instance of an accident when it is “Tesla.”

The video’s real-world example underscores FSD’s current capabilities. In near-zero visibility, the system’s cameras and neural network reacted faster than any human could, demonstrating the life-saving potential Musk cites.

Tesla’s latest safety data already shows FSD (Supervised) performing significantly better than the U.S. average, with crashes occurring far less frequently per mile driven.

Still, regulatory scrutiny, liability concerns, and media focus on edge-case failures continue to slow widespread adoption. Musk’s frank admission suggests Tesla is prepared to push forward despite the legal and perceptual headwinds.

As FSD edges closer to unsupervised autonomy, Musk’s post serves as both a progress report and a reality check. The technology is already saving lives today.

The unfortunate truth is that proving it and scaling it responsibly will require society to value statistical lives saved as much as dramatic stories of those lost. In the race toward safer roads, perception may prove as formidable an obstacle as the fog and rain in that viral video.
