WE HAVE A 2001 DUTCHSTAR CLASS A MOTORHOME, BUILT ON WORKHORSE CHASSIS NUMBER 28321. I AM WRITING FOR A NUMBER OF REASONS. THE FIRST BEING THAT I AM REQUESTING INFORMATION ON POSSIBLE RECALLS THAT INCLUDE THIS UNIT. I UNDERSTAND THAT THERE ARE TWO CAMPAIGNS FOR THE 2001 WORKHORSE CHASSIS, NHTSA # 04V084000, HAVING TO DO WITH SERVICE BRAKES, HYDRAULIC AND # 01V317000, HAVING TO DO WITH SUSPENSION:REAR:SPRINGS:LEAF SPRING ASSEMBLY:U-BOLT, LEAF SPRING TO AXLE. I WOULD LIKE TO KNOW WHETHER OUR UNIT IS INCLUDED AND IF SO, WHY WE WERE NOT NOTIFIED. THE SECOND REASON I AM WRITING HAS TO DO WITH THE ABS BRAKE SENSORS ON THE FRONT WHEELS. IN OCTOBER OF 2003, WE HAD TO HAVE THE RIGHT BRAKE SENSOR REPLACED AFTER IT HAD BURNED UP WITH ONLY 13,523 MILES ON THE UNIT. ON JULY 6, 2004, BOTH FRONT ABS BRAKE SENSORS BURNED UP AND REQUIRED REPLACING WITH ONLY 16,367 MILES. LUCKILY, WE WERE TRAVELING AT A LOW SPEED AS THE LACK OF THE SENSORS APPARENTLY CAUSED BOTH FRONT BRAKES TO LOCK UP, WHICH COULD HAVE BEEN EXTREMELY DANGEROUS HAD WE BEEN TRAVELING ON THE HIGHWAY INSTEAD OF A CITY STREET. WHILE I REALIZE THAT THE UNIT IS OUT OF THE 3 YEAR WARRANTY, THIS APPEARS TO BE A MANUFACTURERS DEFECT WHEN THE SAME UNITS BURN UP WITHIN 3000 MILES. I HAVE ALSO SPOKEN TO A FRIEND THAT HAS A 2002 W22 CHASSIS AND SHE HAS HAD THE SAME PROBLEM, CAUSING HER TO REPLACE BOTH FRONT SENSORS. THESE SENSORS SHOULD BE DESIGNED TO LAST A LOT MORE THAN 16,000 MILES AND CERTAINLY MORE THAN 3,000 MILES. I FEEL THAT WORKHORSE SHOULD TAKE RESPONSIBILITY AND REIMBURSE US FOR THE COST ($365.35) OF THE REPLACEMENT OF BOTH ABS BRAKE SENSORS. *LA

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.

04V084000 · Service Brakes, Hydraulic

Feb 18, 2004

ON CERTAIN MOTORHOME CHASSIS EQUIPPED WITH BOSCH ZOPS, THE PADS CAN DRAG ON THE ROTOR SURFACE DUE TO THE PIN SLIDE.

Consequence & remedy

Consequence: A HANG UP OR LOCK UP MAY CAUSE THE CALIPERS TO OVER HEAT AND NOT ALLOW THE DRIVER TO STOP SAFELY. THIS COULD CAUSE OVERHEATING OF THE BRAKE CALIPERS WHICH COULD RESULT IN A VEHICLE FIRE.

Remedy: DEALERS WILL INSPECT, REPAIR AND REPLACE ACCORDING TO THE PROCEDURE DEVELOPED BY BOSCH (SEE CAMPAIGN 03E064000). THE RECALL BEGAN ON AUGUST 1, 2004. OWNERS SHOULD CONTACT WORKHORSE AT 1-877-294-6773.

01V317000 · Suspension:rear:springs:leaf Spring ASSEMBLY:U-BOLT, Leaf Spring To Axle

Oct 4, 2001

VEHICLE DESCRIPTION: MOTOR HOME AND COMMERCIAL CHASSIS. THE REAR AXLE U-BOLTS MAY NOT BE TIGHTENED CORRECTLY DUE TO RANDOM FAILURE OF PRODUCTION TOOLING IN THE SPECIFIED TIME SPAN.

Consequence & remedy

Consequence: LOW U-BOLT TORQUE CAN RESULT IN U-BOLTS COMING LOOSE AND NOT PROPERLY RETAINING THE REAR AXLE TO THE VEHICLE, RESULTING IN A LOSS OF VEHICLE CONTROL.

Remedy: DEALERS WILL TIGHTEN THE REAR AXLE U-BOLTS. OWNER NOTIFICATION IS EXPECTED TO BEGIN OCTOBER 10, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT WORKHORSE AT 1-877-946-7731.
