2015 RV, PURCHASED NEW IN 2014. TO THIS DAY - LESS THAN 5000.00 MILES. BROKE DOWN X3 WITHIN THE PAST YEAR (TWICE BROKEN DOWN ON THE HIGHWAY-WITH SERVICES NEEDED TO TOW TO A DEALERSHIP WHO COULD HANDLE ASSESSMENT & REPAIR OF A 31 FOOT RV). FIRST TWO TIMES-CODES RETRIEVED FROM THE COMPUTER WERE P025A AND P025B (FUEL PUMP DRIVER MODULE). CURRENTLY AT A DEALERSHIP FOR ASSESSMENT/REPAIR - SEEMS TO BE THE SAME PROBLEMS AS THE LAST TWO TIMES (VEHICLE "BUCKING" AND THEN SHUT DOWN). POWER STEARING AND POWER BREAKS BECOME MANUAL-HARDER TO NAVIGATE TO THE SIDE OF THE ROAD - OFF TO SAFETY. SAFETY RISK TO PEOPLE TRAVELING IN THE RV AND ALSO TO OTHERS ON THE HIGHWAY. HAVING CONCERNS REGARDING SAFETY AND STABILITY OF THIS RV. REALIZE THIS HAS BEEN AND PROBABLY WILL BE STILL COVERED UNDER WARANTEE, HOWEVER, HOW MANY TIMES DOES THIS VEHICLE NEED TO BREAK DOWN...
