Shares slid 3.0% to $374.38 Thursday afternoon as Tesla found itself squeezed between a worsening safety investigation, a shrinking vehicle lineup, and a charging network it's now sharing with virtually every competitor — all while the broader market buckled under Iran-US tensions and surging oil prices.
A Federal Probe That Could Force a Recall of 3.2 Million Cars
NHTSA escalated its investigation into Tesla's driver-assistance system to an Engineering Analysis — the final step before the agency can seek a recall — covering an estimated 3.2 million vehicles.
The scope now includes nine incidents involving one fatality and one injury. The core issue: Tesla's camera-only system may not detect common road conditions like glare, dust, or fog, or warn drivers before a crash.
A serious recall or ban would strike at the heart of the Tesla investment story, especially as it bets its future on robotaxis. With three concurrent NHTSA investigations now open into the system , Tesla's autonomous ambitions face their steepest regulatory wall yet.
Killing the Model S and X to Make Robots Instead
Tesla will discontinue the Model S and Model X by the end of Q2 2026 , with South Korea becoming the first country where Tesla has officially set a March 31 order deadline. The models' impact was already negligible: In Q4 2025, "other models" including Model S, X, Cybertruck, and Semi accounted for just 11,642 unit deliveries versus 406,585 for Model 3/Y — roughly 2.8% of sales.
Tesla is converting Fremont factory space to manufacture its Optimus humanoid robot as part of a $20 billion capital spending plan for 2026. The bet is bold: swapping proven car revenue for a robot that has zero commercial sales.
Opening the Charger Network Helps Competitors Catch Up
Stellantis EVs can now charge on Tesla's Supercharger network — the largest in North America — making Stellantis the last major brand to gain access. Charging fees generate revenue, but the network was once Tesla's exclusive competitive edge for buyers. Now GM, Polestar, Rivian, Lucid, and others all have access , eroding a key reason consumers chose Tesla over rivals.
The Delivery Problem Funding Everything Else
UBS cut its Q1 2026 delivery estimate to 345,000 vehicles, down 18% from Q4 and 7% below consensus. That matters because the cash funding Tesla's robotaxi program, Optimus, and its $20 billion capital budget comes almost entirely from selling cars. Fewer cars means less cash for Tesla's most ambitious bets — at the worst possible time.
