NHTSA Complaint #11711830 — 2025 TOYOTA TUNDRA

Vehicle: 2025 Toyota Tundra Component/System: Powertrain / Electronic Throttle Control / Transmission Response Complaint Description: I am reporting a serious safety defect involving delayed and inconsistent acceleration from a stop or low speed. What failed or malfunctioned: The vehicle exhibits a significant delay in throttle response. The electronic throttle and/or transmission fails to deliver engine power when the accelerator is pressed. The vehicle is available for inspection upon request. Safety risk: This failure creates a hazardous condition when entering intersections, turning across traffic, or merging. On multiple occasions, the truck failed to accelerate when commanded. In one incident, I pressed the accelerator approximately 75% and the vehicle did not respond for 2–3 seconds, nearly resulting in a collision. Reproduction/confirmation: The issue has occurred multiple times under normal driving conditions from a stop or slow roll. It is intermittent and unpredictable. Inspections: At this time, the issue has not yet been resolved and has not been successfully corrected. (Inspection pending / not yet corrected.) Warning indicators: No warning lights, messages, or fault indicators were present before or during the failure. The hesitation occurs without any dashboard alerts. Additional details: The delay is not typical turbo lag or minor hesitation — it is a complete loss of commanded acceleration for several seconds, followed by sudden engagement. This condition makes the vehicle unsafe to operate in traffic.
