NCAP overall
4 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
THE FRONT AIR BRAKE HOSES CAN CONTACT THE INNER FENDER EXTENSIONS.
Consequence
THIS INTERFERENCE CAN CHAFE THE BRAKE HOSES TO THE POINTOF RUPTURE, RESULTING IN LOSS OF FRONT BRAKES WITH POTENTIAL FOR AN ACCIDENT.
Remedy
CUT OUT A PORTION OF INNER FENDER EXTENSIONS TO PREVENT INTERFERENCE. ALSO, REPLACE ANY DAMAGED FRONT BRAKE HOSES.
Defect
THE POWER STEERING ASSIST CYLINDER MOUNTING BRACKET BOLTS MAY LOOSEN DUE TO PAINT ON THE BOLT THREADS AND THE MOUNTING BRACKET MATING SURFACE. CONSEQUENCE OF DEFECT: THIS MAY RESULT IN LOOSENESS AND ERRATIC STEERING DURING FULL TURNS. WITH CONTINUED OPERATION POWER CYLINDER COULD DETACH FROM THE FRAME RAIL RESULTING IN RESTRICTED STEERING, SEVERING OF FRONT BRAKE HOSE AND LOSS OF FRONT AXLE BRAKING. WITH EITHER CONDITION, A VEHICLE CRASH COULD RESULT.
Remedy
REMOVE PAINT FROM MATING SURFACES OF BRACKET AND FRAME RAIL; REPLACE POWER STEERING ASSIST CYLINDER MOUNTING BOLTS.
Defect
THE FUEL RETURN HOSE BETWEEN THE SWITCHING VALVE AND THE FUEL TANK SENDING UNITS MAY BE INCORRECTLY CONNECTED. CONSEQUENCE OF DEFECT: FUEL SUPPLIED BY ONE TANK IS RETURNED TO THE OTHER TANK WHICH COULD OVERFILL AND LEAK. FUEL COULD IGNITE AND CAUSE A FIRE.
Remedy
REPOSITION FUEL RETURN HOSES AND REPLACE FUEL VAPOR CANISTER.
Defect
THE FRONT AIR BRAKE HOSE MAY CONTACT THE INNER FENDER ON THE LEFT AND/OR RIGHT SIDES OF SOME TRUCKS. IN SOME INSTANCES, THE BRAKE HOSE MAY RUB THROUGH, RESULTING IN A LOSS OF AIR PRESSURE UPON BRAKE APPLICATION. CONSEQUENCE OF DEFECT: BRAKE HOSE MAY RUB THROUGH CAUSING AIR PRESSURE LOSS WHEN BRAKES ARE APPLIED AND REDUCED BRAKING ABILITY. A REDUCTION OF BRAKING ABILITY AT A TIME WHEN MINIMUM STOPPING DISTANCE IS REQUIRED COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.
Remedy
INSTALL NEW BRAKE CHAMBER SUPPORT BRACKETS, BRAKE LINE ELBOWS, AND AIR BRAKE HOSES, AS NECESSARY.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 4 recalls should be verified as completed.
