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

09V110000 · Service Brakes, Hydraulic

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.

Consequence & remedy

Consequence: THE TEMPERATURE INCREASE AT THE WHEEL END CAN EVENTUALLY LEAD TO SOFT PEDAL CONDITIONS DUE TO BRAKE FLUID BOIL, AND POSSIBLE EXTENDED STOPPING DISTANCE INCREASING THE RISK OF A CRASH.

Remedy: WORKHORSE DEALERS WILL REPLACE ALL FOUR BOSCH BRAKE CALIPER ASSEMBLIES FREE OF CHARGE. THE SAFETY RECALL BEGAN ON SEPTEMBER 16, 2010. OWNERS MAY CONTACT WORKHORSE AT 1-877-246-7731.
