ON CERTAIN COMMERCIAL BUSES EQUIPPED WITH VAPOR DOOR ASSEMBLIES, THE TWO PIECE CURVED CONNECTING RODS WHEN USED AS AN ELEMENT OF THE DOOR ACTUATION LINKAGE IN CONJUNCTION WITH A VAPOR MEDIUM PNEUMATIC DIFFERENTIAL ENGINE, MAY BE SUBJECT TO FATIGUE FAILURE RESULTING IN BENDING OR BREAKING OF THE CONNECTING ROD.
Safety risk
A BROKEN CONNECTING ROD CAN ALLOW THE DOOR PANEL TO MOVE FREELY IN AN UNCONTROLLED MANNER, LEAVING PASSENGERS INSIDE THE VEHICLE UNPROTECTED BY THE DOOR PANEL AND ENABLING A PROTRUDING DOOR PANEL TO STRIKE PERSONS OR OBJECTS OUTSIDE THE VEHICLE.

ON CERTAIN TRANSIT BUSES, 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.
Safety risk
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.
