2014 Entegra CORNERSTONE: complaints, problems and recalls

RADIATOR TANK STARTED LEAKING AT A RATE OF OVER 15 QTS PER HOUR ON TRIP TO FLORIDA. KEPT FILLING WITH WATER TO GET 2 HOURS TO FINAL DESTINATION. REPLACEMENT OF RADIATOR WAS DONE AT NORTH TRAIL RV IN FORT MEYERS AT MY EXPENSE OF $6,195.34. SPARTAN MOTORS IS THE MANUFACTURER OF THE CHASSIS AND THIS IS A WELL KNOWN AND DOCUMENTED PROBLEM WITH API RADIATORS. THEY HAVE REPLACED MANY OF THEM TO DATE, MY COACH WAS JUST 6 MONTHS OUT OF WARRANTY AND THEY SAID THEY WOULD HELP ME OUT THEY OFFERED $1,000.00 AGAINST ALMOST $6200 BILL. WHY ISN'T THE RV INDU…

Shortly after starting the engine a “CHECK ENGINE” warning appeared on the warning system. I went through diagnostics and found 3 codes relating to DEF head failure. There have been a large number of these in Entegra Coach motor homes in the last 6-12 months.

I HAVE OWNED BOTH A 2019 AND THE NEW 2021 ENTEGRA CORNERSTONE MOTOR HOMES. ON BOTH MOTOR HOMES, THE DIESEL EXHAUST FLUID (DEF) SENSOR HAVE FAILED IN LESS THAT 2,000 MILES.

THE DEF MEASURING DEVICE IN THE DEF TANK FAILED AT AROUND 27,500 MILES. THE DEF MEASURING DEVICE MEASURES QUANTITY AND QUALITY OF THE DEF FLUID. WHEN THIS DEVICE FAILS TO WORK PROPERLY, IT THROWS ECM CODES THAT START TO LIMIT THE ENGINE FOR SPEED AND WILL LIMIT THE MILES THE COACH CAN BE DRIVEN. IF THE COACH CONTINUES TO BE DRIVEN, THE ECM CAN DE-RATE THE ENGINE TO 5MPH. AS YOU CAN IMAGINE, A 45' LONG 13' TALL 8' WIDE COACH WEIGHING 45,000 LBS WHILE TOWING ANOTHER VEHICLE IS DE-RATED AND CAN TRAVEL AT NO MORE THAN 5MPH DOWN THE INTERSTATE WILL …
