2011 Volkswagen Jetta Fuel System Diesel Vehicle Speed Control Engine Problems

SHORTLY AFTER PURCHASING THE VEHICLE NEW WE EXPERIENCED ISSUES WITH THE VEHICLE STUTTERING WHEN DRIVING AND AT TIMES SHUTTING OFF COMPLETELY AS IF IT STALLED (THE VEHICLE IS AN AUTOMATIC WITH THE DSG TRANSMISSION). WE TOOK THE VEHICLE TO THE VW DEALERSHIP UNDER WARRANTY BUT THE TECH COULD NOT REPLICATE THE PROBLEM AND SENT US ON OUR WAY AND TOLD US TO COMEBACK IF IT KEPT OCCURRING. THE PROBLEM PERSISTED AND WE TOOK THE VEHICLE TO THE SERVICE DEPARTMENT AGAIN AND THEY SAID THE PROBLEM COULD NOT BE FOUND AND ONCE AGAIN SENT US AWAY AND TOLD US TO COME BACK IF THE PROBLEM KEPT OCCURRING. THE VEHICLE IS NOW STUTTERING AND STALLING MUCH MORE OFTEN AND THE WARRANTY HAS RUN OUT. I CALLED THE VW HQ THEY TOLD ME TO TAKE THE VEHICLE IN AND HAVE THE TECH LOOK AT IT WHICH HAS COST ME $112 IN WHICH THEY ONCE AGAIN FOUND NOTHING AND RECOMMENDED I LET THE CAR WARM UP PRIOR TO DRIVING. IT IS CURRENTLY SUMMER AND THE LOW TEMPERATURES ARE AROUND 70 AND THE HIGHS ARE 85+. IN ADDITION THIS IS A MODERN VEHICLE AND HAD I KNOW I WAS GOING TO NEED TO LET IT WARM UP I WOULD NOT HAVE PURCHASED IT. THIS ISN?T THE 50?S. MY WIFE AND I NOW FEEL THE VEHICLE IS UNSAFE TO DRIVE DUE TO THE FACT IT STALLS OUT AT UNPREDICTABLE TIMES CAUSING A LOSS OF POWER STEERING, POWER BRAKES. IF VW DOES NOT FIX THIS ISSUE I WILL BE TRADING IT IN DUE TO THEIR DISREGARD FOR SAFETY OF MY FAMILY. *TR
