The vehicle has experienced intermittent loss of power/acceleration when taking off from a stop. When the accelerator pedal is pressed, the vehicle sometimes does not accelerate normally or has substantially reduced power. This creates a safety concern because the vehicle may not accelerate as expected when entering or crossing traffic or in other situations where predictable acceleration is necessary. This has been happening off and on for several month. Around the same time, the vehicle's fuel economy decreased significantly. The vehicle had previously averaged approximately 37 MPG and is now averaging approximately 22–25 MPG under generally similar driving conditions. The vehicle was taken to an authorized Toyota dealership for inspection. The dealership was unable to identify a mechanical problem and reset the vehicle's computers. I was told the reduced fuel economy could be related to the computers relearning my driving habits. After the vehicle was returned to me, the loss-of-power/acceleration condition occurred again, so the issue remains unresolved. There have been no warning lights or dashboard messages associated with the loss of power. The specific component or cause of the malfunction is UNKNOWN. The vehicle is available for further inspection. Toyota corporate has also been notified and has opened a case regarding the unresolved condition.
