Comma.ai preliminary evaluation PE26007
Crashes involving comma.ai driving automation products. NHTSA’s Office of Defects Investigation opened this preliminary evaluation. Opened Sep 21, 2026 and still open — 2 days so far, against NHTSA’s goal of eight months for a preliminary evaluation. open
What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation ("ODI") has identified crashes involving vehicles equipped with devices manufactured by comma.ai (“comma”) occurring under similar circumstances. ODI received notice of five (5) crashes in which vehicles with comma devices installed reportedly struck stopped or slowly moving vehicles within the same travel lane. ODI has confirmed that the systems were powered on or engaged in multiple crashes. Preliminary data reviewed by ODI suggests that the comma system may not have adequately detected or responded to the in-lane vehicles. Two crashes resulted in a total of three (3) fatalities. Four of the five crashes contributed to various non-fatal injuries, including serious injuries, to eleven (11) other individuals. The comma devices are after-market accessory systems intended to augment a vehicle’s driving automation capabilities. The devices are sold with wire harnesses that connect to existing vehicle systems and use the device’s cameras alongside stock vehicle sensors as a basis to provide sustained automated control of speed and vehicle heading with options for other enhanced features enabled by software loaded onto the devices. The devices are sold directly to consumers, and the company’s provided setup instructions are intended for consumer installation. The company advertises on its website that, with its “step-by-step guide,” a consumer can “[g]et set up in your car in 15 minutes.” According to the website, the devices provide “hands free driving for the car you already have,” and the software (openpilot) that comma develops to operate on the devices is described as “an open source advanced driver assistance system that works on 325+ car models” and “[c]an drive for hours without intervention.” The company’s website states that “openpilot requires the driver to be alert, pay attention, and be ready to take over at all times.” ODI is opening this Preliminary Evaluation to investigate further any incidents involving the comma devices and openpilot, particularly crashes involving slower or stopped vehicles or hazards in lane. The investigation will obtain data to verify system status for each incident and evaluate system performance and safeguards that are intended to ensure safe operation of vehicles equipped with comma devices. Additionally, to the extent that modified software based on openpilot (i.e., a “fork”) is involved in a crash or other incident, ODI will evaluate the incident and consider the shared components between openpilot and the fork. The SGO incidents cited in the Opening Resume are listed below by report ID and are available for download at NHTSA.gov/laws-regulations/standing-general-order-crash-reporting 30351-15888 30351-14668 30351-11961 30351-1807 62-14853
A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one is open. Nothing is owed on the vehicle today; if it becomes a recall, owners are written to and the repair is free. The moment to know is the day the campaign number appears — Recall Watch checks each VIN against every new NHTSA campaign and emails you when one lands, or take a free one-line alert by model year.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE26007 a recall?
No. A preliminary evaluation is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one has not produced one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.
Is PE26007 still open?
Yes, as of NHTSA’s latest file: opened Sep 21, 2026, 2 days ago.
Which vehicles does PE26007 cover?
NHTSA filed it against comma.ai without naming a model year.
