1989 Jeep Grand Wagoneer 4WD
Fuel Economy Overview
The 1989 Jeep Grand Wagoneer 4WD achieves an EPA-estimated 11 MPG in combined city and highway driving, with 10 MPG in the city and 12 MPG on the highway. Powered by a 5.9L 8-cylinder engine paired with a automatic 3-spd, this special purpose vehicles features 4-Wheel or All-Wheel Drive drive.
In terms of environmental impact, the 1989 Grand Wagoneer 4WD produces approximately 808 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Grand Wagoneer 4WD has higher-than-average emissions in this regard.
The estimated annual fuel cost for this vehicle is $5,450, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $16,500 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
Aerodynamic Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

Recall Intelligence
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 & Remedy
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.
MALFUNCTION OF FUEL INJECTION SYSTEM THROTTLE POSTITION SENSOR COULD CAUSE INTERMITTENT HIGH ENGINE IDLE SPEED IMMEDIATELY AFTER STARTING ENGINE.
Consequence & Remedy
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.
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 & Remedy
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.
