THE ABOVE VEHICLE WAS PURCHASED ON 10/29/2010, WHILE CONDUCTING THE FIRST 30 DAY RIVING TEST, IT WAS NOTICED THAT THE INSTRUMENT CLUSTER WAS NOT FUNCTIONING PROPERLY, THE DISPLAY LIGHT WILL NOT COME ON AND THEREFORE HAD TO DRIVE IN THE EVENING WITHOUT THIS KNOWLEDGE. DURING THE DAILIGHT, WHEN I PLACED THE VEHICLE IN CRUISE CONTROL THE INSTRUMENT CLUSTER FAILED TO TELL ME SO. THERE ARE MANY OTHER FEATURES TO THIS INSTUMENT THAT I DO NOT KNOW IF THEY WORK OR NOT. UPON BRINGING THE VEHICLE BACK TO THE PURCHASING DEALER, I WAS TOLD THAT THE INSTRUMENT PANEL HAD BEEN PREVIOUSLY RECALLED BY THE MANUFACTURER AND THAT THE WORK HAD ALREADY BEEN COMPLETED ON APRIL 2010 AND THEREFORE IF I WANTED IT FIXED, I WOULD HAVE TO PAY APPROXIMATELY $600.00 TO GET IT FIXED. THIS VEHICLE WAS SOLD TO ME WHILE BEING UNSAFE TO DRIVE, HOW CAN THEY TELL ME THAT I WOULD HAVE TO PAY FOR A SAFETY REPAIR OF THIS MAGNITUDE WHEN IT DID NOT HAPPEN WHILE I OWNED THE VEHICLE. THE WORKHORSE RECALL NUMBER WAS BULLETIN NO. 50402-C. IT IS MY CONTENTION THAT THE DEALERSHIP SHOULD PAY FOR THIS VERY IMPORTANT PART OF THE SAFETY OF THIS VEHICLE.

LTR RE: SAFETY RECALL 50901-C INTERIM NOTICE DATED MAY 2009 WORKHORSE HE THINKS HE SHOULD BE REIMBURSE FOR THE DAMAGES INCURRED IN SEPT. 2007 FROM THIS DEFECT, ALSO PAY FOR THE DIAGNOSIS OF THIS PROBLEM. *NJ THE CONSUMER STATED HE EXPERIENCED BRAKE FAILURE PRIOR TO RECEIVING A RECALL LETTER. WORKHORSE DENIED THE CONSUMERS CLAIM STATING THE REPAIRS WERE NECESSARY, BECAUSE IT WAS THE CONSUMERS FAULT THAT THE BRAKES OVERHEATED. THE ROTORS WERE SEVERELY DAMAGED. THE CONSUMER STATED HE HAD NO CONFIDENCE THAT THE PROBLEM HAD BEEN FIXED EVEN THOUGH THE REPAIRS WERE MADE, THE ABS LIGHT WOULD STILL ILLUMINATE. THE CONSUMER STATED HE HAD SPOKEN TO A WORKHORSE ADVISOR TWICE PRIOR TO THE BRAKE FAILURE. HE REPORTED THE STEERING WHEEL WAS VIBRATING WHEN HE APPLIED THE BRAKE. THE CONSUMERS WIFE ALSO SMELLED BURNT BRAKES EVEN THOUGH THE CONSUMER WAS ONLY TAPPING THE BRAKES TO SLOW DOWN. THE ADVISOR TOLD THE CONSUMER IT DID NOT MAKE SENSE THAT WHEN STEPPING ON THE BRAKE, THE STEERING WHEEL WOULD VIBRATE AND THAT IT WAS NOT A BRAKE PROBLEM. A VISUAL INSPECTION REVEALED THAT THE BRAKE PADS SEEMED OK, BUT THE FRONT ROTORS AND ONE OF THE REAR ROTORS WERE TOTALLY BROKEN. THE SERPENTINE BELT WAS REPLACED BECAUSE IT WAS MAKING A LOT OF NOISE, THE SPARK PLUGS BURNED 4 TIMES, THE PIXELS WENT OUT ON THE ODOMETER, THE INSTRUMENT CLUSTER SHUT DOWN COMPLETELY, THE TRANSMISSION LOCKED UP ONCE IN THIRD GEAR, THE SEAT BELT LIGHT ILLUMINATED FOR NO REASON AND THEN WOULD GO OUT AND A REAR SEAL ON THE AXLE LEAKED. *JB

I HAVE A HOLIDAY RAMBLER VACATIONER MOTOR HOME WITH A WORKHORSE CHASSIS THERE IS A RECALL NHTSA # 06V22700 FOR AN INSTRUMENT CLUSTER PANEL, WHICH WAS REPLACED ON MY VEHICLE, THAT CONTINUES TO BLANK OUT INTERMINTANTLY CAUSING THE PANEL TO GO DARK AT NIGHT, BUZZING ALARM, AND ALL THE GUAGES TO RESET. I HAVE CALLED WORKHORSE 3/2/07 TO REPORT THAT THE CONDITION CONTINUES, BUT THEY STATED THAT THEY ARE STILL WORKING ON A FIX. IT IS THREE YEARS SINCE THE CONDITION STARTED HOW LONG ARE WE TO WAIT? IS IT POSSIBLE THAT THE REPLACEMENT PANEL WAS ALSO BAD? CAN THE NHTSA BOARD HELP ME WITH THIS MATTER? THANK YOU FOR YOUR CONSIDERATION. *JB

SINCE TAKING DELIVERY IN APRIL 2004, PERIODICALLY INSTRUMENT PANEL FAILS FOR SHORT PERIODS. ALL GAUGES GO TO ZERO AND ALL WARNING LIGHTS COME ON AND REMAIN IN THIS STATE FOR 5 - 45 SECONDS. MY WIFE PANICKED THE LAST TIME AND ALMOST CRASHED INTO A GUARD RAIL. WORKHORSE REPROGRAMMED COMPUTER MODULE TWICE (THERE WAS A RECALL INVOLVING BRAKE WARNING LIGHT). THEY THOUGHT THIS WOULD FIX MY PROBLEM, BUT IT DID NOT. THEY HAVE REPORTED TO ME FOR THE LAST TWO YEARS THAT THEY ARE WORKING ON A FIX. DATE IS LAST INSTANCE, BUT IT HAPPENS ON EVERY TRIP AT LEAST ONCE. AT A RECENT GATHERING OF OWNERS ABOUT 20 PEOPLE ACKNOWLEDGED THAT THEY ARE HAVING THE PROBLEM. *NM

Apr 3, 2009

NAVISTAR IS RECALLING CERTAIN MODEL YEAR MY 2001-2008 WORKHORSE W20, W21 AND W22 CHASSIS AND CERTAIN MODEL YEAR 2009 THROUGH 2011 MONACO RV ADMIRAL, ARISTA, MONARCH, AND RIPTIDE RECREATIONAL VEHICLES EQUIPPED WITH AXLES THAT INCLUDE BOSCH ZOPS OR ZOHT PIN SLIDE HYDRAULIC DISC BRAKES. WHEN COMBINED WITH OCCASIONAL OR SEASONAL VEHICLE OPERATION MAY EXPERIENCE CALIPERS STICKING IN THE APPLIED POSITION. THIS CAN RESULT IN ABNORMAL HEAT GENERATION AT THE WHEEL END CAUSING BRAKE DRAG. THE DRIVER WOULD NORMALLY HAVE WARNING OF THE BRAKE DRAG IF UNDETECTED BY THE DRIVER.
