NCAP overall
3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.
Consequence
THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
Remedy
DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.
Defect
AIR SYSTEM BLOCKAGE IN THE AIR DRYER OCCURS DEGRADING THE MOISTURE REMOVING CAPABILITIES OF THE DRYER WHEN THE VEHICLE IS OPERATED IN A COLD ENVIRONMENT AND MOISTURE ACCUMULATES AND FREEZES IN THE AIR DRYER OR IN THE LINE BETWEEN THE DRYER AND THE AIR SYSTEM RESERVOIR. THE AIR DRYER CAN BECOME OVERPRESSURIZED CAUSING THE AIR DRYER CARTRIDGE TO SEPARATE FROM THE MOUNTING BASE.
Consequence
IF THE AIR DRYER SEPARATES FROM THE BASE, THE CARTRIDGECAN SEPARATE SUFFICIENTLY ENOUGH TO CAUSE PERSONAL INJURY OR PROPERTY DAMAGE.
Remedy
DEALERS WILL EQUIP AIR SYSTEMS WITH A PRESSURE RELIEF VALVE TO BE LOCATED BETWEEN THE COMPRESSOR AND THE AIR DRYER. THIS PRESSURE RELIEF VALVE IS INTENDED TO VENT IF EXCESSIVE PRESSURE DEVELOPS IN THE AIR DRYER.
Defect
THE WRONG BALL SOCKET ASSEMBLY WAS USED TO ATTACH THE STEERING ARMS TO BOTH THE STEERING DRAG LINK AND THE STEERING RAM ASSIST CYLINDER, RESULTING IN A BINDING CONDITION.
Consequence
THIS CONDITION CAN CAUSE THE BALL SOCKET TO FATIGUE, INCREASING THE POTENTIAL FOR LOSS OF STEERING CONTROL AND AN ACCIDENT.
Remedy
DEALERS WILL REPLACE THE BALL SOCKET ASSEMBLY ON THE AFFECTED VEHICLES.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 3 recalls should be verified as completed.
Yes — NHTSA lists 3 recall campaigns affecting the 1993 Whitegmc Wx. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
