2025 Toyota Tundra Fuel System Problems

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.

Your truck suddenly lost power when you tried to accelerate out of a parking lot onto a busy road, leaving you drifting toward oncoming traffic with no way to speed up. Only after shifting to Park, then Sport, then back to Drive was the truck able to accelerate normally again. This appears to be a transmission or engine response issue that created a serious safety hazard.

The throttle lag is a major safety concern. When pulling way from a stop there is a huge delay in throttle response. This is consistent and has caused me to have several close incidents and nearly an accident.

Your truck hesitates or lags when you press the gas pedal, meaning it doesn't respond immediately to acceleration. This delayed response has put you in dangerous situations where other drivers had to brake or swerve to avoid you. The issue appears to affect multiple Tundra owners, but Toyota and dealers haven't provided a fix yet. Resolving this will likely require the dealer to reprogram the engine control module or replace the throttle body sensor.

Your truck hesitates when you accelerate from a complete stop, with a 1-2 second delay even when you push the pedal all the way down. This delay has nearly caused accidents and only happens right after you've come to a complete stop. The issue likely involves the fuel system or engine's response sensors, and may require diagnostic testing and possible replacement of fuel system components or sensor recalibration.

Your truck's fuel economy is significantly worse than EPA estimates — you're getting around 14.6 MPG instead of the advertised 18-23 MPG. With only 16,000 miles on the truck, you're concerned this gap suggests the EPA ratings may be inaccurate. A fuel system inspection and engine tune-up may help identify why your truck isn't meeting its rated efficiency.

Your truck hesitates and lurches when you press the accelerator. This means you might feel a jerky or uneven response rather than smooth acceleration. The issue could stem from fuel delivery, ignition timing, or engine sensor problems, and you may want to have a mechanic perform a diagnostic scan to identify the root cause.
