Complaint Summary

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Owner Narrative

I am submitting this complaint to request an investigation into a serious safety defect involving my Tesla vehicle. On multiple occasions, the vehicle has experienced a significant and unexpected loss of acceleration when I attempted to enter or cross intersections. Despite pressing the accelerator, the vehicle failed to respond as expected, leaving me unable to accelerate normally while entering active traffic. This is not a minor hesitation or inconvenience. It is a serious roadway safety hazard. Drivers rely on immediate acceleration when crossing intersections, turning across traffic, or merging. A vehicle that unexpectedly limits acceleration can place occupants directly in the path of oncoming vehicles, creating a substantial risk of a severe collision, serious injury, or death. I reported this issue to Tesla Service and provided multiple timestamps documenting the events. Tesla was unable to identify any fault codes or provide a diagnosis and indicated that because no fault was recorded, the issue could not be confirmed. Through independent research, I found numerous reports from other Tesla owners describing substantially similar acceleration limitation events. Many reports specifically reference Obstacle Aware Acceleration as a possible cause, and some owners report that disabling the feature resolved the issue. If a safety system can falsely detect an obstacle and reduce acceleration while a driver is actively entering an intersection, the system itself may create a greater danger than the one it is designed to prevent. I respectfully request that NHTSA investigate whether Tesla vehicles are experiencing unexpected acceleration limitation or torque reduction during intersection entry and traffic merging situations, evaluate the role of Obstacle Aware Acceleration and related software systems, determine whether a broader pattern exists, and assess whether corrective action or a recall is warranted. This could cause serious injury or fatal crash
