Tesla (TSLA) stock falls on report of alleged Department of Justice criminal probe
Shares of Tesla (NASDAQ:TSLA) fell by more than 5% in midday trading Tuesday following a report that the Silicon Valley electric carmaker is under investigation by the US Justice Department over statements made by company CEO Elon Musk last month pertaining to the company’s possible privatization and the fact that funding had been “secured.”
News of the Justice Department’s investigation was related to Bloomberg News by two individuals familiar with the matter. The criminal investigation will reportedly run alongside a previously reported civil inquiry by the Securities and Exchange Commission (SEC). The criminal investigation is reportedly in its early stages.
Federal prosecutors reportedly opened the fraud investigation due to Elon Musk’s now-infamous “funding secured” tweet last August 9, which resulted in TSLA stock soaring 11% to $387.46, according to the publication’s sources. Inasmuch as the announcement pushed the company’s stock near its all-time highs on the day of Musk’s tweet, TSLA stock began a long trek down as questions emerged about the source of funding the CEO was referring to in his tweet.
Few details are currently known about the ongoing investigation. That being said, Justice Department probes like the civil inquiries being undertaken by the SEC, are known to take months to complete, with investigations at times ending with prosecutors deciding to take no enforcement action.
A few days after announcing that he is thinking of taking Tesla private, Elon Musk published a blog post stating that the “funding secured” tweet came from talks he has had with Saudi Arabia’s sovereign wealth fund, which took a 5% stake in Tesla earlier this year. The weeks following these announcements were incredibly volatile, as SEC investigations were reportedly begun, lawsuits were filed, and TSLA shares took a dive.
Tesla, for its part, began the process for its possible privatization. Musk hired several high-profile advisers including bankers from Goldman Sachs, as well as attorneys from Wachtell, Lipton, Rosen & Katz. He also hired Silver Lake Partners’ Egon Durban, who brokered and helped bankroll the buyout of Dell when it went private. By August 22, Tesla’s advisers had a list of possible investors that would provide funding for the company’s privatization at $420 per share.
Among the investors that were willing to fund Elon Musk’s go-private initiative were German auto giant Volkswagen AG, as well as Silver Lake Partners itself. Together, the investors reportedly agreed to contribute as much as $30 billion for the deal. At this point, though, Elon Musk already had reservations, particularly since it would be incredibly difficult to bring over TSLA’s retail investors into a privatized Tesla.

Ultimately, Elon Musk opted to walk out of a possible $30 billion deal. An announcement about the company staying public was posted on Tesla’s official blog soon after. Since then, Tesla has focused itself on its original Q3 2018 targets — that is, the continued production ramp of the Model 3 and the company’s aim to become profitable. The company appears poised towards a record quarter, particularly after Elon Musk noted in a letter to employees that Tesla is “about to have the most amazing quarter in (its) history, building and delivering more than twice as many cars as (it) did last quarter.”
Following is Tesla’s official response to the reported DOJ investigation.
“Last month, following Elon’s announcement that he was considering taking the company private, Tesla received a voluntary request for documents from the DOJ and has been cooperative in responding to it. We have not received a subpoena, a request for testimony, or any other formal process. We respect the DOJ’s desire to get information about this and believe that the matter should be quickly resolved as they review the information they have received.”
As of writing, Tesla stock is trading down 2.22% at $288.27 per share.
This story is currently developing.
Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
-
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled

Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
