Limited data — recalls on file
NHTSA has just 2 complaints on file for the 1977 Mercury Monarch — too few to judge reliability from owner reports alone — but 4 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

4 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
THE ENGINE COOLING FAN BLADES MAY CRACK UNDER HIGH SPEED OPERATING CONDITIONS. FRAGMENTS MAY SEPARATE AND DAMAGE THE ENGINE COMPONENTS, AND IF THE HOOD IS OPEN AND THE ENGINE IS RUNNING, BLADE FRAGMENTS COULD FLY OUT FROM THE VEHICLE AND INJURE NEARBY PERSONS.
Remedy
THE DEALER WILL, WHERE NECESSARY, INSTALL A NEW FAN FREE OF CHARGE.
Defect
ON THE INVOLVED VEHICLES, THE MANUAL STEERING GEARS MAY CONTAIN STEERING GEAR RECIRCULATORY BALLS THAT COULD FRACTURE. THIS FRACTURING IS A RESULT OF IMPROPER HEAT-TREATMENT DURING MANUFACTURE AND CAN EVENTUALLY CAUSE INCREASED STEERING EFFORT.
Remedy
THE DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE BALL BEARINGS OF THE STEERING GEAR, WITHOUT CHARGE TO OWNER.
Defect
THE INVOLVED VEHICLES WERE FITTED WITH TILT STEERING COLUMNS CONTAINING TRANSMISSION CONTROL INSERTS INTENDED FOR TRUCKS RATHER THAN PASSENGER VEHICLES. THIS MAY CAUSE THE TRANSMISSION SELECTOR POINTER TO BE MISALIGNED AND THE POSSIBILITY OF STARTING THE ENGINE WHEN THE SELECTOR IS BETWEEN THE NEUTRAL (N) AND DRIVE (D) DETENTS AND THE TRANSMISSION IS IN DRIVE.
Remedy
DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE TRANSMISSION SHIFT CONTROL INSERT, WITHOUT CHARGE TO OWNER.
The record is thin — 2 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 4 recalls should be verified as completed.
Yes — NHTSA lists 4 recall campaigns affecting the 1977 Mercury Monarch. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
