NCAP overall
3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
A BRACKET INSTALLED TO SECURE A HIGH IDLE COMPONENT ONTO THE ENGINE THROTTLE ARM CAN HOOK THE WIRE HARNESS AND PREVENT ITS RETURN TO IDLE SPEED.
Consequence
THE ENGINE THROTTLE CAN STICK PARTIALLY OPEN RESULTING IN LOSS OF THROTTLE CONTROL AND AN ACCIDENT.
Remedy
DEALERS WILL RELOCATE THE HIGH IDLE BRACKET AWAY FROM THE THROTTLE LINKAGE AND SECURE THE WIRING HARNESS AWAY FROM THE THROTTLE LINKAGE.
Defect
THE AIR COMPRESSOR AIR SUPPLY LINE IS ROUTED FROM THE COMPRESSOR OVER THE TOP OF THE FRAME RAIL, UNDER THE BRAKE HYDROMAX, AND DOWN TO THE AIR SYSTEM. THIS LINE CAN CONTACT THE STEEL SECTION OF THE HYDROMAX HYDRAULIC SUPPLY LINE, CAUSING A LEAK TO OCCUR IN THE HYDRAULIC LINE, ALLOWING HYDRAULIC FLUID TO LEAK ON THE LEFT FRONT WHEEL AND BRAKE ASSEMBLY.
Consequence
THE LEAK ALLOWS ENOUGH FLUID TO BE PUMPED FROM THE SYSTEM TO ELIMINATE POWER STEERING ASSIST. THE ELECTRONIC SECONDARY BRAKE PUMP WILL ENGAGE, BUT THE LEAK WILL RESULT IN INCREASED STOPPING DISTANCE.
Remedy
DEALERS WILL INSTALL A CUSHION CLIP ON THE TOP LEFT FRAME RAIL SEPARATING AND ELIMINATING ANY CONTACT BETWEEN THE STEEL JACKETED AIR LINE AND THE METAL SECTION OF THE HYDRAULIC LINE.
Defect
A GAP BETWEEN THE MASTER CYLINDER AND REMOTE BRAKE FLUID RESERVOIR ADAPTER IS CAUSED BY AN OUT-OF-SPECIFICATION CONDITION IN THE ADAPTER, RESULTING IN HYDRAULIC FLUID LOSS DURING BRAKE APPLICATION.
Consequence
BRAKE FLUID LOSS RESULTS IN LOSS OF PRESSURE, CAUSINGPARTIAL LOSS OF BRAKING ABILITY.
Remedy
REPLACE THE OUT-OF-SPECIFICATION ADAPTERS.
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.
