Defect: ON CERTAIN TRANSIT BUSES, THERE IS A POSSIBILITY THAT THE HYDRAULIC LINE COMING FROM THE RADIATOR FAN MOTOR TO THE CAC MOTOR IS RUBBING ON THE CHASSIS.
Consequence: THIS RUBBING MAY CAUSE THE HYDRAULIC LINE TO BE RUBBED THROUGH RESULTING IN A LEAK AND A LOSS OF HYDRAULIC FLUID. THIS FLUID COULD IGNITE IF IT COMES IN CONTACT WITH A HOT SOURCE.
Remedy: DEALERS WILL INSTALL A P-CLAMP ON THE RADIATOR MOTOR SUPPORT BRACKET THAT HOLDS AND SECURES THE HOSE AWAY FROM THE CHASSIS ELIMINATING THE POSSIBILITY OF CHAFFING. THE RECALL BEGAN ON AUGUST 24, 2005. OWNERS MAY CONTACT OPTIMA AT 1-888-391-1777.
Defect: ON CERTAIN TRANSIT BUSES WITH CUMMINS ISB02 ENGINES, THE HYDRAULIC LINE COMING OFF OF THE POWER STEERING PUMP IS RUBBING ON TOP OF THE AIR GOVERNOR.
Consequence: THIS RUBBING MAY CAUSE THE HYDRAULIC LINE TO BE RUBBED THROUGH RESULTING IN A LEAK AND A LOSS OF HYDRAULIC FLUID. THIS FLUID COULD IGNITE IF IT COMES IN CONTACT WITH A HOT SOURCE.
Remedy: DEALERS WILL MAIL A MODIFICATION KIT WITH INSTRUCTIONS ON HOW TO INSTALL A BRACKET AND CLAMP THAT WILL LIFT AND SECURE THE LINES AWAY FROM THE AIR GOVERNOR ELIMINATING THE POSSIBILITY OF CHAFFING. THE RECALL BEGAN ON MAY 20, 2005. OWNERS MAY CONTACT OPTIMA AT 1-888-391-1777.
Defect: ON TROLLEYS AND TRANSIT COACHES EQUIPPED WITH CUMMINS ISB DIESEL ENGINES, THE FUEL LIFT PUMP COULD FAIL IN A MANNER WHICH RESULTS IN ENGINE FUEL STARVATION, WHICH COULD RESULT IN A STALL CONDITION. POTENTIAL LIFT PUMP FAILURE MODES INCLUDE: BRUSH WEAR OUT, BUSHING FAILURE, ROTOR TAB INSERT FAILURE, OR ANY OTHER FAILURE MODE THAT WOULD CAUSE THE FUEL PUMPING ELEMENT TO STOP SPINNING.
Consequence: IF THE FUEL LIFT PUMP PUMPING ELEMENT STOPS SPINNING AND THE FUEL PUMPING VANES STOP IN A LOCATION WHICH BLOCKS FUEL FLOW THROUGH THE LIFT PUMP, THE ENGINE WILL BE STARVED OF FUEL. FUEL STARVATION COULD CAUSE LOW ENGINE POWER, ENGINE MISFIRE, OR ENGINE STALL. PRIOR TO THE ENGINE STALLING, THE OPERATOR COULD EXPERIENCE LOW ENGINE POWER, ENGINE MISFIRE, AND/OR DASH-MOUNTED FAULT LAMP ILLUMINATION.
Remedy: CUMMINS IS CONDUCTING THE OWNER NOTIFICATION AND REMEDY FOR THIS CAMPAIGN. OWNERS MAY CONTACT CUMMINS AT 1-800-343-7357 OR OPTIMA AT 316-779-7700.

Notes on this record
Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
NHTSA's complaints API and bulk file list no complaint for this make, model and model year in this data build.
