NHTSA Launches Investigation into Approximately 1,000 Tesla Cybercabs
The NHTSA initiated an audit inquiry AQ26002 on September 3 for about 1,000 Tesla Cybercab Robotaxis to review their self-certification compliance with federal motor vehicle safety standards, coinciding with the day of commercial deployment in Austin.
The Cybercab is a two-seat dedicated Robotaxi without a steering wheel, pedals, or rearview mirrors. Tesla has stated to the NHTSA that it has completed self-certification in accordance with applicable FMVSS and plans to gradually expand the vehicles and operational locations, unlike Zoox, which applied for a Part 555 temporary exemption.
The NHTSA is focusing on Tesla's certification process and technical data, particularly whether certain standards were deemed inapplicable due to the absence of traditional manual controls. On September 10, a special order was issued requiring sworn responses to 21 questions, originally due by September 30 but extended to October 30, with Tesla having requested an extension to November 20.
The special order inquires whether temporary manual controls were removed after certification, whether the touchscreen can control movement, operational speed and geographic restrictions, and how to meet FMVSS No. 135 requirements without a foot brake. Failure to fully or truthfully respond may result in fines of up to approximately $28,000 per day.
Initial deployment of vehicles in Austin is limited, with Texas records showing about 45 vehicles registered initially. Subsequent community tracking indicates an increase in unsupervised service vehicles in Austin. The NHTSA's investigation scope anticipates planned expansion, alongside a separate investigation into approximately 3.2 million vehicles equipped with FSD.
Regulatory scrutiny is driven by commercial deployment events, with funding and resources directed towards certification compliance and software updates. Beneficiaries include competitors like Zoox that have exemption pathways, while Tesla's Robotaxi commercialization process, which relies on self-certification for rapid expansion, is under pressure.
The NHTSA emphasizes support for AV innovation but insists on legal compliance, while also pushing for modernization of FMVSS to accommodate vehicles without manual controls. The investigation's outcome may impact future production and operational permits.

Tesla has previously faced multiple NHTSA investigations regarding its FSD system, including a preliminary evaluation PE25012 in 2025 for about 2.88 million vehicles related to red light and wrong-way violations, as well as visibility-related upgrades to engineering analysis, involving dozens of complaints and accident reports. Historical trends show that software iterations often accompany regulatory upgrades rather than immediate recalls.
On the capital front, Tesla positions Robotaxi as a core growth area, initiating validation through commercial charging for Austin Cybercab, shifting resources from traditional vehicle sales to dedicated vehicles without steering wheels and FSD data loops. The motivation is to bypass exemption processes for accelerated deployment, avoiding the Zoox-style Part 555 limit of 2,500 vehicles per year, while integrating xAI to enhance perception.
Similar cases include Amazon's Zoox, which applied for and received a two-year exemption in July 2026 to deploy control-free Robotaxis, and Waymo's multiple NHTSA preliminary evaluations regarding school bus stops and speed limits in school zones. Currently, Tesla is in a phase of commercialization expansion, relying on self-certification rather than pre-approval.
This essentially reflects regulatory changes: FMVSS is shifting from assuming human drivers to accommodating ADS, with mechanisms allowing self-certification as a default pathway for rapid market entry. However, audits and special orders compel disclosure of technical bases, and when hardware designs exceed existing standards, regulators recalibrate safety boundaries through information requests and potential penalties to prevent commercialization from prioritizing compliance verification.
