Car will not start at seemingly random times. car either has to be towed to dealership or in some instances left alone for hours at a time. sometimes after letting it rest, it will start again and others not. this has occured 4 times so far and each time the dealership tried fixing the ecm and eventually replaced it, but it continues to occur. i have been stranded a number of times with a new baby and vw continues to try to fix the problem to no avail.
