You can only ask the dealer too help you and they do not satisfy you then contact the manufacturer. If they cannot resolve the situation then it may take legal action. There is no easy or right answer too your problem. Each dealer and each manufacturer resolve each situation differently. What they do for someone else they may not do for you. Unless you have a performance contract on the equipment you are at there mercy.
I will add that the manufacturers do watch forums. It may be beneficial too post a detailed account of what is going on in a professional manner with proper grammer and spelling. Sometimes dealers will take the" hope it goes away" approach too problems so your problem may not ever reach the manufacturer.
Also equipment should rarely break down. It is not common for a machine to have major problems that early on.
