VEHICLE ACCELERATED WHEN TAKING FOOT OFF GAS (ENGINE REVVED) AND ACCELERATED ON ITS OWN CAUSING VEHICLE TO SPIN OUT DURING WINTER DRIVING CONDITIONS AND SENT VEHICLE SMASHING INTO CEMENT BARRIER. VEHICLE HAS ACCELERATED ON ITS OWN SINCE DRIVING OFF LOT IN NOVEMBER, 2016. AT FIRST I THOUGHT THIS WAS AN ISSUE WITH THE FOUR WHEEL DRIVE, BUT IT'S CLEARLY AN ACCELERATION ISSUE. I'VE ALSO TESTED THIS AND WAS ABLE TO MAKE IT NEARLY 1.5 MILES FROM MY HOME, MOSTLY UP HILL WITHOUT EVEN STEPPING ON THE GAS. IN ADDITION, MY REAR TIRES SPIN WHEN IN DRIVE WHEN ON SNOW OR ICE WHEN NOT ENGAGING THE GAS PEDAL. ENGINE REVS WHILE THIS HAPPENS, AS IT DID DURING MY COLLISION. TOYOTA CURRENTLY HAS VEHICLE AND ADVISED THAT THIS CASE WAS ESCALATED TO CORPORATE DUE TO CIRCUMSTANCES. *TR
