Verdict · NHTSA data
Limited data — recalls on file
NHTSA has just 10 complaints on file for the 1986 Lincoln Mark Vii — too few to judge reliability from owner reports alone — but 5 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work. Reports tied to this model year include one death, per the complaint records themselves.

5 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
SPRING LOCK FUEL LINE COUPLING MAY NOT BE PROPERLY ENGAGED.
Consequence
COUPLING COULD DISENGAGE DUE TO FUEL PRESSURE,VIBRATION, AND ENGINE MOVEMENTS; THIS WOULD CAUSE LOSS OF FUEL WHICH, INPRESENCE OF AN IGNITION SOURCE, CREATES A FIRE RISK.
Remedy
INSTALL RETAINER CLIPS OVER THE COUPLINGS TO PREVENT COUPLING SEPARATION AND FUEL LEAKAGE.
Defect
THE IGNITION LOCK CYLINDER MAY HANG UP AND NOT FULLY RETURN TO THE "ON" POSITION FROM THE "START" POSITION AFTER STARTING THE ENGINE. IF THIS OCCURS, THE ENGINE WILL REMAIN RUNNING, BUT THE BATTERY CURRENT TO THE BRAKE SYSTEM SUPPLY MOTOR WILL BE INTERRUPTED. CONSEQUENCE OF DEFECT: WITH POWER TO MOST ACCESSORIES AND THE BRAKE SYSTEM SUPPLY MOTOR INTERRUPTED, THE POWER ASSIST TO THE FRONT BRAKE WILL BE LOST AND AFTER ABOUT 10 TO 15 NORMAL BRAKE STOPS, LOSS OF REAR BRAKE FUNCTION WILL RESULT, CAUSING INCREASED STOPPING DISTANCE. HOWEVER, THE INSTRUMENT BRAKE WARNING LIGHT WILL ILLUMINATE PRIOR TO REDUCED BRAKING CAPABILITY AND IF WARNING IS NOT HEEDED, AN ACCIDENT MAY OCCUR.
Remedy
REPLACE IGNITION LOCK CYLINDERS WITH REVISED DESIGN CYLINDERS.
Defect
UNDER CERTAIN CONDITIONS, CONTACTS IN BRAKE SYSTEM RELAY COULD REMAIN CLOSED, CAUSING THE BRAKE PUMP MOTOR TO RUN CONTINUOUSLY, CAUSING IT TO OVERHEAT AND EVENTUALLY FAIL. CONSEQUENCE OF DEFECT: SHOULD THE BRAKE SUPPLY MOTOR FAIL, THE POWER ASSIST TO THE FRONT BRAKES WILL BE LOST, AND AFTER ABOUT 10 TO 15 NORMAL BRAKE STOPS, LOSS OF REAR BRAKE FUNCTION WILL RESULT, CAUSING INCREASED STOPPING DISTANCE. HOWEVER, THE INSTRUMENT BRAKE WARNING LIGHT WILL ILLUMINATE PRIOR TO REDUCED BRAKING CAPABILITY AND IF WARNING IS NOT HEEDED, AN ACCIDENT MAY OCCUR.
Remedy
REPLACE PUMP MOTOR RELAYS.
Defect
WIRING CONNECTIONS IN AN ELECTRICAL CONNECTOR TO THE MASTER CYLINDER RESERVOIR FLUID LEVEL SENSORS WERE REVERSED AND FAIL TO INDICATE LOW FLUID LEVELS AS SPECIFIED BY FMVSS 105, HYDRAULIC BRAKE SYSTEMS. CONSEQUENCE OF DEFECT: SENSOR WILL NOT TRANSMIT SIGNAL TO BRAKE WARNING LIGHT WHEN THE FLUID LEVEL IS LESS THAN ONE FOURTH FULL. WITHOUT THIS WARNING SIGNAL THE FLUID LEVEL MAY DECREASE TO THE POINT WHERE PARTIAL OR COMPLETE LOSS OF BRAKE WOULD BE EXPERIENCED AND MAY LEAD TO AN ACCIDENT.
Remedy
RE-CONFIGURE WIRING TO THE FLUID LEVEL SENSOR CONNECTOR.
Defect
AN ALUMINUM CASTING FLASH ON THE FACE OF THE THROTTLE BODY MAY BREAK OFF AND BECOME TRAPPED BETWEEN THE THROTTLE PLATE AND THE BORE IN THE THROTTLE BODY. CONSEQUENCES OF DEFECT: THROTTLE MAY FAIL TO RETURN TO IDLE POSITION WHEN RELEASED AND COULD RESULT IN LOSS OF VEHICLE CONTROL WHICH MAY CAUSE AN ACCIDENT.
Remedy
REMOVE EXCESS CASTING FLASH.
The record is thin — 10 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 5 recalls should be verified as completed.
According to NHTSA complaint data, the leading problem areas are electrical system (3 complaints), engine (2 complaints), fuel system (1 complaints).
