I was attempting to back my vehicle slowly into a parking space. I came to a stop after observing a vehicle in an adjacent space that appeared to be moving. At that point, while my foot was on what I believed was the brake pedal, the vehicle accelerated rearward rapidly and uncontrollably. I attempted to apply the brake but the vehicle continued accelerating backward at high speed. The vehicle struck three parked vehicles before stopping, causing significant property damage and vehicle body damage to my Camry. The acceleration felt involuntary and beyond my control. The pedal response did not correspond to my intended input. Given the vehicle's age (34 years), I am concerned that one or more of the following mechanical conditions may have contributed to this incident: deterioration or binding of the throttle cable within its conduit; throttle return spring fatigue or failure causing the butterfly valve to remain partially open; or carbon accumulation on the throttle body bore causing the valve to stick in a partially open position. None of these components have been inspected or serviced to my knowledge. I am aware that Toyota issued early recall actions NHTSA Recall Nos. 86V-132 and 90V-040 related to unintended acceleration on startup in Toyota vehicles of this generation, and that Toyota was subsequently penalized $1.2 billion in 2014 for concealing unintended acceleration defects across its vehicle lines. I am filing this complaint to create an official record of this inc
