NHTSA opens formal audit into ~1,000 Tesla Cybercabs
The NHTSA opened a formal audit (Open Audit Query AQ26002) into roughly 1,000 Tesla Cybercabs, examining the basis Tesla used to certify the driverless two-seater meets federal vehicle safety standards despite lacking a steering wheel, pedals or mirrors. The probe began the same day Tesla launched commercial service in Austin — regulatory risk resurfacing just as the robotaxi went live.
Hours after Tesla put Cybercab into commercial service in Austin on September 3, NHTSA's Office of Defects Investigation moved from a vague "evaluating" comment to a formal review.
The inquiry is registered as Open Audit Query AQ26002 and covers roughly 1,000 Cybercab vehicles. At issue is the basis for Tesla's own certification: Cybercab is a purpose-built two-seat autonomous vehicle with no steering wheel, brake pedal, accelerator pedal or side mirrors, while most Federal Motor Vehicle Safety Standards (FMVSS) assume a human-driven car. NHTSA says it will examine how Tesla determined which FMVSS provisions don't apply to the vehicle.
Reuters, WSJ and TechCrunch all confirmed the probe's opening. Regulatory risk has resurfaced just as the robotaxi moves into commercial operation — depending on what the audit finds, it could lead to a recall, service restrictions, or a formal exemption requirement. It is not, at this stage, a defect finding or an order to halt operations.
The morning after launch, Tesla shares opened lower — a reversal from the prior day's rally on robotaxi optimism — as Wall Street reaction (WSJ called the launch underwhelming) combined with the NHTSA news to weigh on sentiment. That said, this reflects intraday trading; the close-to-close move has yet to be confirmed.
Reuters analysis (Sept. 4) notes regulatory gray areas could work in Tesla's favor: since federal vehicle-safety standards (FMVSS) were written assuming a human driver, experts say Musk's litigious track record raises the chance Tesla self-certifies Cybercab compliance via a "creative interpretation" and floods the market before NHTSA or state regulators can resolve the question — a process that could take years, potentially letting the service keep expanding while the audit is pending.
