Recall History (12 recalls)

05V084000Apr 2005

ENGINE AND ENGINE COOLING

05V189000Jun 2005

SUSPENSION

ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS, THE SUSPENSION HAS TRANSVERSE BEAM CASTINGS THAT MAY FRACTURE UNDER NORMAL LOADS.

SUSPENSION:REAR

ON CERTAIN TRUCKS AND TRACTORS EQUIPPED WITH AIRGLIDE HIGH-ARTICULATION REAR SUSPENSIONS, THE C65-1006 SWAY BAR USED IN THIS REAR SUSPENSION MAY EXPERIENCE A REDUCTION IN FATIGUE LIFE DUE TO EITHER A MANUFACTURING PROCESS OR A HIGH INDUCED STRESS DURING AN EXTREME SUSPENSION ARTICULATION EVENT.

STEERING

ON CERTAIN TRUCKS EQUIPPED WITH THE BENDIX ELECTRONIC STABILITY CONTROL (ESP) SYSTEM, THE SYSTEM USES MULTIPLE SENSORS AND AN ELECTRONIC CONTROL UNIT (ECU) TO CONTROL VEHICLE UNDER STEER, OVER-STEER, AND ROLLOVER SITUATIONS. THE SYSTEM RELIES ON VEHICLE SENSORS TO BE FUNCTIONING AND ALIGNED PROPERLY. THE STEERING ANGLE SENSOR HAS THE POTENTIAL TO BE MISALIGNED WITH THE STEERING COLUMN SHAFT, THEREBY PROVIDING INCORRECT INFORMATION TO THE BENDIX ECU.
