ENGINE, IN IDLE AND IN GEAR, SUDDENLY SURGED. IT PROPELLED THE CAR FORWARD IN DRIVEWAY AND STRUCK A CAR ABOUT 1 FOOT-18 INCHES IN FRONT OF IT, DAMAGING FRONT BUMPER OF OUR CAR AND REAR BUMPER OF OTHER CAR. DAMAGE TO OUR CAR WAS QUOTED AT $878 AND SECOND CAR (OUR GRANDDAUGHTER'S) WAS LESS. REPORTED TO TOYOTA. THEY SENT ANALYST TO CHECK "BLACK BOX" AND REPORTED TO ME ACCELERATOR PEDAL AND BRAKES WERE OK. NOT CAR'S FAULT. I HAVE EXPERIENCED THIS SURGE MANY TIMES SINCE LEASING THE CAR 30 MONTHS AGO BUT NO ACCIDENTS. EACH TIME I REPORTED IT TO DEALER. SERVICE MAN SAID HE FOUND NOTHING WRONG. *TR
