Elon Musk is under investigation over CEO benefits received from Tesla and whether they were properly disclosed. According to a new report, the perks may date back further than investigators previously realized, and broadened interest from federal prosecutors appears to signal the pursuit of potential criminal charges.
Federal prosecutors are conducting an investigation of Musk and Tesla over the disclosure and use of company resources for various personal benefits, including a project to build a house for the CEO, according to a report from The Wall Street Journal. Musk is under investigation from the U.S. Department of Justice (DOJ) over the Tesla benefits, which may date back as far as 2017. Additionally, criminal charges could be on the table.
The WSJ says it spoke with “an array of people” about Tesla and the government investigations for this report.
According to people familiar with the matter, the U.S. Attorney’s Office for the Southern District of New York has also been investigating Musk for transactions made between Tesla and other entities connected to him. Prosecutors on the case have alluded to potential involvement from a grand jury, the WSJ reports.
In addition, a separate civil investigation has been opened into allegations of the house project for Musk by the Securities and Exchange Commission (SEC). The housing plans were internally dubbed “Project 42,” set to construct a large glass building near Tesla’s Gigafactory Texas.
The SEC requires publicly traded companies to disclose executive perks and benefits if their total exceeds $10,000, including reimbursement for private security, housing or airplane use. Companies are also required to disclose transactions over $120,000 in which executive officers have a material interest.
Notably, Musk posted last year about wanting to build himself a home on a nearby horse farm on the other side of the Colorado River from Giga Texas. He met with an architect to talk designs and even suggested utilizing a glass shard coming out of a lake, according to Walter Isaacson’s recent biography of the billionaire. Ultimately, Isaacson says Musk just “put off building it.”
Project 42 and its purpose were considered a secret within the company, the WSJ explains.
When employees became worried about the use of millions of dollars in glass panels ordered by Tesla, lawyers and board members began scrutinizing the project. One such concerned party reportedly included former CFO Zachary Kirkhorn, who stepped down last month but will remain through the end of the year.
Earlier this month, Musk denied claims of his plans to have Tesla build a glass house or any house in a post on X, and he and his representatives didn’t respond to the WSJ’s requests for comment.
Just want to reiterate that there is no glass house (metaphors don’t count lol) built, under construction or planned!
I’m not building any house of any kind anywhere. Period.

“Companies have been paying attention to the SEC’s enforcement efforts and tightening their controls in this area, which is likely resulting in changes to perks or increased disclosures,” says Sidley Austin lawyer and regulatory enforcement group leader Stephen L. Cohen. “But I believe there is also a view at the SEC that the public cares about executive perks.”

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
