Tesla began commercial Cybercab service in Austin on Thursday, September 3, and opened it more widely the following day. NHTSA’s Office of Defects Investigation opened Audit Query AQ26002 the same day, covering roughly 1,000 vehicles.
NHTSA says it will “examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues,” and specifically the extent to which that certification rested on Tesla deciding that certain federal safety standards do not apply to the car at all.
Every vehicle sold in the United States is certified by its own manufacturer. The government runs no approval step and no type inspection before the first car ships. The manufacturer affixes a label saying the vehicle meets every applicable Federal Motor Vehicle Safety Standard, and the government’s role begins after that.
Tesla used that system exactly as written.
The complication is the word applicable. FMVSS were drafted around a person sitting behind a wheel, and a two-seat car with no wheel, no pedals and no mirrors forces someone to decide which of those rules still bind. Zoox asked the government to make that call and waited nearly a year for an answer. Tesla made the call itself.
Key Takeaways
- An audit query is an investigative step, not an enforcement action. The opening documents order no recall, no stop-sale and no service halt. A September 10 Special Order requires Tesla to answer 21 requests under oath by September 30.
- Tesla filed no exemption petition. It self-certified the Cybercab as compliant with every standard it determined applies, which is the default path for every carmaker in the country.
- Self-certification carries no volume ceiling. The Part 555 exemption route Zoox used caps a manufacturer at 2,500 vehicles introduced into commerce in any 12-month period, the maximum federal law allows.
- NHTSA’s stated concern is the reasoning, not the hardware. The agency notes the Cybercab “lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors.”
- The audit population is far larger than the fleet. About 45 Cybercabs were registered to Tesla’s robotaxi fleet in Texas records as of August 31. AQ26002 covers roughly 1,000.
- Zoox reached the same road by the opposite route. It applied in August 2025, was granted Temporary Exemption No. 2026-01 in July 2026, and its waiver names eight standards and expires in two years.
What Tesla Did Instead of Asking
The American system is self-certification. A manufacturer determines which standards apply to its vehicle, tests against them, and certifies compliance on its own authority. Nothing in federal law requires a company to seek permission first, and nothing keeps a self-certified automated vehicle off public roads.
A carmaker can meet FMVSS 111 by installing the mirrors and rear visibility display the standard demands. It can also conclude that a paragraph written to govern a driver-side mirror has no meaning in a vehicle with no driver’s seat, and that the requirement therefore does not attach.
Those are different claims. The first is a test result. The second is a legal interpretation, and it is the one NHTSA has asked Tesla to show its work on.
Why this differs from the FSD investigations. NHTSA’s open defect investigation into 2.88 million Teslas over red-light behavior asks whether software performs safely in the field. AQ26002 asks whether the paperwork behind a compliance label holds up. A vehicle can drive flawlessly and still be improperly certified, and it can be properly certified and still drive badly.
What an Audit Query Is and Is Not
NHTSA’s Office of Defects Investigation runs several kinds of file. A Preliminary Evaluation and an Engineering Analysis look for a safety defect. An Audit Query examines a manufacturer’s own process, most often the adequacy of a recall or, as here, the basis for a certification.
The opening documents order nothing. No recall, no stop-sale, no suspension of service. Tesla continues carrying passengers in Austin while the audit runs, and the company has announced plans to expand to more vehicles and more cities.
On September 10, NHTSA Chief Counsel Peter Simshauser signed a Special Order under AQ26002. It contains 21 requests, and Tesla must answer by September 30 under an officer’s sworn affidavit, with civil penalties of up to $27,874 a day, capped at $139,356,994, for failing to respond. Request 21 asks Tesla to explain how the Cybercab complies “without any exemption under 49 CFR Part 555.”
The order’s questions reach FMVSS 101, 102, 108, 111, 126 and 135. Three of those, 101, 102 and 126, fall outside the eight standards in Zoox’s exemption.
What an audit query can produce is a finding that vehicles were sold without meeting a standard that did apply. That outcome is a noncompliance recall, and the remedy for a noncompliance is the same as for a defect: fix it, replace it, or buy it back. On a car with no steering column to install one into, the remedy question gets difficult quickly.
“NHTSA fully supports the safe development and deployment of automated vehicles,” the agency said. “But as the federal regulator, we need to ensure that all of our laws are followed.”
The Standards Written Around a Driver
Tesla has not published the list of standards it determined inapplicable to the Cybercab, and NHTSA has not published it either. What exists in public is the list Zoox needed waived for a vehicle with a comparable problem, and it is a useful map of where a car without controls collides with the rulebook.
| Standard | What it normally requires |
|---|---|
| FMVSS 103 | Windshield defrosting and defogging |
| FMVSS 104 | Windshield wiping and washing |
| FMVSS 108 | Self-cancelling turn signal control and headlamp beam switch |
| FMVSS 111 | Inside mirror, driver-side mirror, rear visibility display |
| FMVSS 135 | Service brakes operated by a foot control |
| FMVSS 201 | Sun visor |
| FMVSS 205 | AS1 glazing in the windshield |
| FMVSS 208 | Airbag warning label on the sun visor |
A sun visor rule, a mirror rule and a foot-pedal brake rule are not safety philosophy. They are equipment specifications for a seat that a Cybercab does not have.
The Cybercab has no steering wheel, no accelerator or brake pedal, no side mirrors and no rear window, and it runs a camera-only sensing stack. Two seats, butterfly doors, a central screen.
Zoox Took 11 Months and a 2,500-Vehicle Ceiling
Zoox applied to NHTSA on August 22, 2025, under Part 555, the provision that lets the agency exempt a small number of vehicles from standards they cannot meet. NHTSA published the application that September, the docket took comments, objectors filed against it, and the grant arrived at the end of July 2026.
Temporary Exemption No. 2026-01 names its eight standards, runs two years, and caps Zoox at 2,500 vehicles introduced into commerce in any 12-month period. That ceiling is not a number NHTSA chose. It is the statutory maximum, and no exemption can exceed it.
Zoox also did not start there. It self-certified its robotaxis in 2022 and petitioned only after a federal inspection found what NHTSA called multiple apparent noncompliances.
The exemption grants less than it appears to. NHTSA wrote that its analysis was “limited to the specific requirements under the FMVSS for which Zoox sought an exemption,” and that the agency “has not made any conclusions regarding whether the vehicle otherwise complies with all other applicable FMVSS requirements.” A Part 555 grant waives named rules. It does not certify that a robotaxi drives well, and it is separate from the operating permission that comes from NHTSA authorization and state licensing.
2,500 Vehicles a Year Against a $30,000 Car
Zoox operates a fleet it owns inside a Las Vegas geofence. At that scale, 2,500 vehicles a year is a ceiling the company will not touch for years.
Tesla is building toward something else. Elon Musk has held to a target price at or below $30,000, which is a consumer number rather than a fleet-procurement number, and Tesla lists more than 125,000 units a year of installed Cybercab capacity at Gigafactory Texas. The first unit came off the line in February 2026 and production started in the second quarter, though Tesla’s July shareholder update dropped the Cybercab from its list of 2026 volume-production launches.
A 2,500-unit annual ceiling is fatal to that plan.
It is roughly a week of output from a line built for a mass-market car, and it would cap the Cybercab at a rounding error against Tesla’s other products for as long as the exemption governed it.
Self-certification carries no such limit. A manufacturer that certifies compliance can build as many vehicles as it can sell. The trade is that the determination stands on the manufacturer’s own analysis, and the government tests it afterward.
45 Cars Inside an Austin Geofence
Texas motor vehicle records showed 45 Cybercabs registered to Tesla’s robotaxi fleet as of August 31, and Tesla described its September launch as a limited deployment it intends to expand.
Riders book through Tesla’s robotaxi app inside a geofenced part of Austin. Early fares varied by route and demand. A Not a Tesla App comparison priced one Cybercab trip at $7.77 against $12.10 for a Model Y on the same route, while the Austin American-Statesman was quoted $12.15 for a 2.5-mile Cybercab ride that Uber priced at $7.96.
NHTSA estimates the audit population at 1,000 vehicles, well beyond the Austin fleet.
Tesla has not commented publicly on the audit.
What Happens If NHTSA Disagrees
Three outcomes are available. The agency can accept Tesla’s reasoning and close the file, which would settle self-certification as a route to market for vehicles without controls and make the Part 555 process optional for everyone behind Tesla.
It can find the certification deficient in part, which would produce a noncompliance recall on a specific standard and force a remedy on hardware that was designed without it.
Or it can conclude the vehicles required an exemption they never obtained. That is the outcome with no clean fix, because the remedy for selling a vehicle that cannot comply is not a software update.
Regulators have been rewriting this corner of the rulebook throughout 2026, including work to streamline the exemption process for automated vehicles. Whatever AQ26002 concludes will land on top of rules that are themselves in motion.
What the Audit Settles
NHTSA has not questioned how the Cybercab drives, and it has not told anyone to stop riding in one. The question is whether a manufacturer can decide on its own that the rules written for a driver’s seat stop applying when the seat is gone.
Zoox spent 11 months and accepted a 2,500-vehicle ceiling to get a government answer to that question in writing, for eight named standards, for two years. Tesla answered it internally and started selling rides. Both cars are on public roads today.
For a rider in Austin, the practical effect is none. For every company building a vehicle without controls, AQ26002 is the file that determines whether the exemption process is a requirement or a formality, and whether the ceiling that comes with it is one they need to plan around.
Frequently Asked Questions
What is NHTSA investigating about the Tesla Cybercab?
NHTSA opened Audit Query AQ26002 on September 3, 2026, covering roughly 1,000 Cybercabs. The agency is examining the process and technical data Tesla relied on when it certified the vehicle as meeting federal safety standards, and in particular the extent to which Tesla concluded that certain standards do not apply to a car without manual controls.
Does the audit mean the Cybercab has been recalled?
No. An audit query is an investigative step. The opening documents order no recall, no stop-sale and no halt to service, and Tesla continues operating the vehicles in Austin. A September 10 Special Order does require Tesla to answer 21 requests under oath by September 30.
Did Tesla get government approval to build a car with no steering wheel?
No, and it did not need to ask for one in advance. The United States uses manufacturer self-certification. Tesla affixed a compliance label on its own authority, which is the same mechanism every carmaker uses for every vehicle it sells.
How is this different from what Zoox did?
Zoox applied under Part 555 for an exemption from eight specific standards, waited about 11 months, and received Temporary Exemption No. 2026-01 in July 2026. Tesla filed no petition and sought no exemption.
What is the 2,500-vehicle cap?
A Part 555 exemption limits a manufacturer to 2,500 vehicles introduced into commerce in any 12-month period. It is the statutory maximum, and it applies to manufacturing volume rather than fleet size. Self-certification carries no equivalent limit.
Which safety standards does a car without a steering wheel run into?
The Zoox exemption named eight: windshield defrosting and defogging, windshield wiping and washing, the turn signal and headlamp beam controls, mirrors and rear visibility, foot-operated service brakes, the sun visor, AS1 windshield glazing, and the airbag warning label attached to the visor. Tesla has not published its own list.
Where can you ride in a Cybercab?
Inside a geofenced portion of Austin, Texas, booked through Tesla’s robotaxi app. Tesla began commercial service on September 3, 2026 and has said it plans to expand to more vehicles and additional locations.
How much does a Cybercab ride cost?
Fares have varied by route and demand. One comparison priced a Cybercab trip at $7.77 against $12.10 for a Model Y; the Austin American-Statesman was quoted $12.15 for a 2.5-mile Cybercab ride that Uber priced at $7.96. Tesla has not published a fare schedule.
How many Cybercabs are there?
Texas motor vehicle records showed about 45 registered to Tesla’s robotaxi fleet as of August 31, 2026. NHTSA’s audit covers roughly 1,000 vehicles, a wider population than the cars carrying passengers.
Can you buy a Cybercab?
Not yet. Musk has held to a target of $30,000 or less, but Tesla published no consumer price at the Austin launch and the vehicle is operating as a fleet robotaxi.
What could NHTSA do if it disagrees with Tesla’s certification?
A finding that vehicles were sold without meeting an applicable standard would produce a noncompliance recall, with the same remedy obligations as a defect recall: repair, replacement or repurchase. On hardware designed without the equipment a standard requires, a repair is not always available.
Does this have anything to do with the Full Self-Driving investigations?
No. NHTSA’s open defect investigation into 2.88 million Teslas concerns how the software behaves at red lights. AQ26002 concerns whether the Cybercab’s certification paperwork is sound, which is a separate question from how the vehicle drives.
