The Office of Defects Investigation (ODI) received a DP on September 23, 2026, requesting an investigation into model year (MY) 2026 Tesla Robotaxis (Model Y and Cybercab) with the Automated Driving System (ADS) engaged. The Petitioner alleges that the ADS exceeds posted speed limits in active school zones.
Along with the request, the Petitioner provided 3 links to video footage as supporting evidence.
A DP has been opened to evaluate the allegations and determine whether to grant or deny the petition.
The petition itself can be reviewed at NHTSA.gov under ODI Number: 11766676.

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\u2019s driving automation capabilities. The devices are sold with wire harnesses that connect to existing vehicle systems and use the device\u2019s 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\u2019s provided setup instructions are intended for consumer installation. The company advertises on its website that, with its \u201cstep-by-step guide,\u201d a consumer can \u201c[g]et set up in your car in 15 minutes.\u201d According to the website, the devices provide \u201chands free driving for the car you already have,\u201d and the software (openpilot) that comma develops to operate on the devices is described as \u201can open source advanced driver assistance system that works on 325+ car models\u201d and \u201c[c]an drive for hours without intervention.\u201d The company\u2019s website states that \u201copenpilot requires the driver to be alert, pay attention, and be ready to take over at all times.\u201d
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 \u201cfork\u201d) is involved in a crash or other incident, ODI will evaluate the incident and consider the shared components between openpilot and the fork.

On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations. The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla\u2019s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.

These complaints allege a hard brake pedal, followed by a \u201cBrake System Failure\u201d message at start up or while driving.
GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual \u201cService Brake System\u201d message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH).
Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM\u2019s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM\u2019s eBoost system to resulting in safety-related outcomes.
At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles.
ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system.

This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement.
General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM\u2019s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy.
To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure.
ODI is opening this Engineering Analysis to continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.
