2016 RAM PROMASTER Fuelpropulsion System Problems

THROTTLE IS" UNPREDICTABLE" AND SLOW TO RESPOND, WITH A DELAY OR NO RESPONSE AT TIMES. WHEN IN MOTION AND THE WHEEL TURNED, IT HAS LURCHED FORWARD ON IT'S OWN. SITTING AT INTERSECTION WITH WHEEL TURNED AND WAITING FOR TRAFFIC TO CLEAR TO MAKE TURN WITH ONCOMING TRAFFIC, THROTTLE WAS PRESSED DOWN AND THEN ALL THE WAY TO FLOOR WITH NO RESPONSE UNTIL REPEATING THE ACTION AND THEN SHOOTING FORWARD UNEXPECTEDLY. 3 TIMES NEARLY INVOLVED IN ACCIDENT BECAUSE OF UNPREDICTABLE THROTTLE RESPONSE. CAR HAS LESS THAN 500 MILES AND IS ELECTRONICALLY CONTROLED THROTTLE. DEALER THEN REPLACED TRANSMISSION AND WHAT EVER ELSE THEY DID AND THE SITUATION GREATLY IMPROVED BUT STILL SLOW RESPONSE AND UNPREDICTABLE WHEN DRIVING. THIS HAS BEEN A DIRE SAFETY HAZARD WHILE I AM DRIVING AND THE DEALER SAYS NONSENSE WHEN I COMPLAIN. IT IS A PROBLEM WHEN TRYING TO BE SENSITIVE WITH THROTTLE. WHEN MASHING DOWN ON THROTTLE...
