U.S. regulators have opened an investigation into 2.6 million Teslas after reports of crashes involving the use of company technology that allows drivers to remotely command their vehicle to return to them, or move to another location, using a phone app.

The National Highway Traffic Safety Administration also said Tuesday that Tesla did not report any of the accidents. Tesla is under order to report crashes on “publicly accessible roads” involving vehicles being operated through its autonomous driving technology.

The new investigation follows another probe launched in October looking into the company's “Full Self-Driving” system after getting reports of crashes in low-visibility conditions, including one that killed a pedestrian. That investigation covers 2.4 million Teslas from the 2016 through 2024 model years.

Tesla did not respond to a request for comment from The Associated Press on Tuesday.

One driver filed a complaint after a crash while using Tesla's “Actually Smart Summon” technology and NHTSA is looking into another three similar incidents based on media reports, the NHTSA said. The agency is looking into 12 total incidents reported by users of the technology.

Each of the vehicles failed to detect posts and other parked vehicles, according to the NHTSA.

Regulators say the vehicles struck objects because the users had "too little reaction time to avoid a crash, either with the available line of sight or releasing the phone app button, which stops the vehicle’s movement.”

Shares of Tesla Inc., based in Austin, Texas, slid more than 4% in late afternoon trading Tuesday.

Musk has complained that U.S. regulations are too onerous and are holding back the development of self-driving cars. Ethics experts are worried that once President-elect Donald Trump takes office, Musk will push him to ease oversight of Tesla, which just suffered its first decline in annual sales in more than a decade.

Musk donated an estimated $250 million to Trump's presidential campaign and is a frequent guest at Trump's Mar-a-Lago, vetting cabinet nominees and meeting with foreign heads of state. Trump has put Musk in charge of an advisory group, the Department of Government Efficiency, that will recommend where to cut government expenses and staff at federal agencies and reduce regulation.

The NHTSA said Tuesday it will look into the top speed that Teslas can reach when users deploy its “summons” technology, as well as restrictions on public roads and line of sights requirements. It also said it expects to check for any “connectivity delays" with the app that could result in increased stopping distance.

Tesla’s Model 3 owner’s manual says that its “summons” feature is designed for use only in parking lots and driveways on private property and is disabled on public roads.

The new probe covers 2016-2025 Model S and X vehicles, 2017-2025 Model 3, 2020-2025 Model Y equipped with Tesla's Full Self-Driving driver assistance system.

Electric truck charging network expands to Houston-Dallas freight corridor

electric trucking

Greenlane Infrastructure, an electric public charging station developer and operator, is expanding outside of its home state of California and into Texas.

The Santa Monica-based company plans to launch its high-power charging sites along the Dallas–Houston I-45 corridor, which is one of the highest-volume commercial trucking routes in the country, according to a news release from Greenlane.

The sites will feature 6-8 pull-through lanes with chargers supporting combined charging system (CCS) and megawatt charging system (MCS) connectors that allow electric truck drivers to recharge their vehicles during standard rest periods. They will also offer tractor parking and charging, as well as operations that will allow for overnight stops.

Drivers can reserve chargers in advance, monitor charging activity in real time, and manage billing from the Greenlane Edge platform.

“Our customers are making commitments to electrify their fleets, and they need a charging network that can grow alongside them,” Patrick Macdonald-King, CEO of Greenlane, said in the release. “This is the first leg of the Texas triangle, one of the more important freight arteries in the country, so bringing high-power charging there is the next logical step in building a network that serves how freight moves across America.”

Greenlane is also expanding across the West Coast, with five locations under development in California and Nevada. It opened its flagship Greenlane Center in Colton, California, in April 2025. The company plans to open locations in Blythe, California, and Port of Long Beach this year.

Greelane was founded in 2023 as a joint venture between Daimler Truck North America, NextEra Energy Resources and BlackRock. It has secured partnerships with electric long-haul truck developer Windrose Technology, Velocity Truck Centers and Volvo Trucks North America.

Houston startup lands $1B from Blackstone and Halliburton, plans acquisition

power deal

Houston-based power generation startup VoltaGrid has nailed down a $1 billion equity investment from asset management heavyweight Blackstone and Houston-based oilfield services provider Halliburton.

The investment comes in two forms:

  • A $775 million primary capital raise
  • A $225 million secondary capital purchase from existing investors

VoltaGrid, founded in 2020, provides behind-the-meter mobile power generation equipment for data centers, microgrids and industrial customers.

Aside from the $1 billion investment, VoltaGrid has agreed to buy Propell Energy Technology, a VoltaGrid supplier, for an undisclosed amount. Propell offers a natural gas power generation platform for AI data centers. VoltaGrid plans to add two manufacturing plants at Propell’s facilities in Granbury, a Dallas-Fort Worth suburb.

The investment and acquisition deals are expected to close in mid-2026.

Funds managed by Blackstone Tactical Opportunities are contributing to the $1 billion investment. William Nicholson, managing director of Blackstone, called VoltaGrid “a highly differentiated platform addressing one of the most important infrastructure needs of the AI era: reliable, rapidly deployable power. This investment is a strong example of Tac Opps’ focus on providing flexible, scaled capital to exceptional entrepreneurs and businesses operating in Blackstone’s highest-conviction investment themes.”

Nathan Ough, founder and CEO of VoltaGrid, said in a release that the Blackstone investment “is a powerful endorsement of the platform we have built and the role VoltaGrid is playing in delivering the energy infrastructure of the AI era.”

Last October, VoltaGrid and Halliburton said they had forged a partnership to supply power for data centers around the world, with the Middle East picked as the initial target. Two months later, the companies said they had arranged the manufacturing of 400 megawatts of natural gas power systems that’ll be delivered in 2028 to support new data centers in the Eastern Hemisphere.

Jeff Miller, president and CEO of Halliburton, said his company’s investment in VoltaGrid “reflects our shared focus on long-term solutions for the world’s most demanding power environments, and advances VoltaGrid’s ability to deliver reliable, distributed power at scale.”
