Known issues on the 1990 Wagoneer. Five recalls are on federal record for this model year: an anti-lock brake fault that can cause loss of the ABS function and reduced power-assist braking, a brake hose detaching from the ABS system and losing the hydraulic brake function, a disc rotor whose cast-iron wear surface can separate from the hub and reduce braking, hydraulic-fluid contamination that can make the anti-lock brake system malfunction, and a high engine idle when first placed in gear from the cruise-control system that can cause unexpected acceleration. Owners have filed 18 complaints and Jeep has issued 10 technical service bulletins for the year.
From a routine service interval to a brake-system overhaul or a hard-to-trace hydraulic fault, it keeps you on the OEM procedure and the correct specification for your specific 1990 Wagoneer.
THERE MAY BE HYDRAULIC FLUID CONTAMINATION FROM CONDENSATION FORMATION THAT CAN PLUG THE ABS BRAKE BOOSTER PUMP FILTER; STRESS CORROSION OF THE MASTER CYLINDER SNAP RING HAS BEEN TRACED TO CHLORINE LEAKING FROM THE LOW PRESSURE HYDRAULIC HOSE WHICH MAY CAUSE IT TO BREAK; FRONT BRAKE HOSE TO TIRE INTERFERENCE WHICH MAY CAUSE FAILURE OF THE BRAKE HOSE.
Consequence
CONTAMINATION OF THE HYDRAULIC FLUID CAN CAUSEMALFUNCTIONING OF THE ANTI-LOCK BRAKE SYSTEM; LOW PRESSURE HOSE LEAKAGE CAUSESLOSS OF BRAKE FLUID AND ALSO RESULTS IN CORROSION AND FAILURE OF THE MASTERCYLINDER SNAP RING, RESULTING COMPLETE BRAKE FAILURE; FAILURE OF THE FRONT BRAKEHOSE DUE TO HOSE TO TIRE INTERFERENCE WILL CAUSE FAILURE OF ONE HALF OF THEBRAKE SYSTEM RESULTING IN A LONGER STOPPING DISTANCE THAN EXPECTED.
Remedy
REPLACE ABS LOW PRESSURE HOSE; REBUILD MASTER BRAKE CYLINDER; INSPECT, SERVICE INTERFERENCE PROBLEMS, AND REPLACE FRONT BRAKE HOSE AS NECESSARY.
IMPROPER INSERTION/CRIMPING OF THE HOSE-TO-END FITTINGS OF THE HIGH PRESSURE HOSE ON THE ANTI-LOCK BRAKE SYSTEM CAN CAUSE DETACHMENT OF THE HOSE FROM THE ABS SYSTEM, AND DISCHARGE OF HYDRAULIC FLUID.
Consequence
DETACHMENT OF THE HOSE FROM THE ABS SYSTEM CAUSES THELOSS OF THE ABS FUNCTION AND HYDRAULIC BRAKE ASSIST, LEAVING ONLY MANUAL BRAKESAND DECREASING STOPPING ABILITY, WHICH COULD RESULT IN AN ACCIDENT. DISCHARGE OFHYDRAULIC FLUID IN THE AREA OF THE HOT EXHAUST SYSTEM COULD RESULT IN AN ENGINECOMPARTMENT FIRE.
Remedy
REPLACE THE ABS HIGH PRESSURE HOSE.
VEHICLE DESCRIPTION: VEHICLES EQUIPPED WITH ANTILOCK BRAKE SYSTEM (ABS). THE ANTILOCK BRAKE SYSTEM (ABS) HYDRAULIC CONTROL UNIT CAN EXPERIENCE EXCESSIVE BRAKE ACTUATOR PISTON SEAL WEAR WHICH COULD CAUSE PUMP-MOTOR DETERIORATION.
Consequence
IF THIS OCCURS, THE ABS FUNCTION WOULD BE LOSE AND REDUCED POWER ASSIST WOULD BE EXPERIENCED DURING VEHICLE BRAKING. THE INSTRUMENT PANEL WARNING LIGHTS WILL SIGNAL SYSTEM IMPAIRMENT AND THE BASE MANUAL BRAKES WILL REMAIN FUNCTIONAL.
Remedy
DEALERS WILL TEST THE VEHICLE'S ABS AND REPAIR AS NECESSARY. THE WARRANTY ON ALL ABS COMPONENTS WILL BE EXTENDED TO 10 YEARS OR 100,000 MILES (EXCEPT FOR THE BRAKE ACTUATOR PISTON ASSEMBLY AND THE PUMP-MOTOR ASSEMBLY WHICH WILL HAVE A LIFETIME COVERAGE). OWNERS WILL BE REIMBURSED FOR PREVIOUS ABS COMPONENT REPAIR COSTS.

THE FRONT DISC BRAKE ROTORS CAN EXPERIENCE SEVERE CORROSION IF OPERATED FOR AN EXTENSIVE PERIOD IN THE "SALT BELT." IF THE ROTORS ARE NOT REPLACED, THE CORROSION CAN EVENTUALLY COMPROMISE THE STRUCTURAL INTEGRITY OF THE STAMPED STEEL CENTER HUB SECTION OF THE ROTOR.
Consequence
THE REDUCED STRENGTH CAN ALLOW THE CAST IRON WEAR SURFACE TO SEPARATE FROM THE HUB, REDUCING THE BRAKE EFFECTIVENESS OF THE VEHICLE.
Remedy
DEALERS WILL REPLACE THESE ROTORS WITH ROTORS THAT ARE COATED WITH A CORROSION PROTECTION.
MALFUNCTION OF FUEL INJECTION SYSTEM THROTTLE POSTITION SENSOR COULD CAUSE INTERMITTENT HIGH ENGINE IDLE SPEED IMMEDIATELY AFTER STARTING ENGINE.
Consequence
HIGH ENGINE IDLE WHEN CAR IS FIRST PLACED IN GEAR COULDRESULT IN UNEXPECTED ACCELERATION.
Remedy
REPLACE THROTTLE POSITION SENSORS WITH SENSORS THAT WOULD SEND CORRECT SIGNALS TO THE FUEL INJECTION SYSTEM.
