Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1977 Marquis.
For researchers examining the 1977 Mercury Marquis, the available data outlines a reliability profile defined by a singular owner complaint. This lone issue centers on the Service Brakes, Hydraulic system, occurring alongside exactly one recall notice issued for the vehicle. Ultimately, the 1977 Marquis occupies a notably stable position in the model's reliability history, indicating a low frequency of defects for owners during this period.
Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 1977 Mercury Marquis registers a minimal federal footprint in the data provided, with only a single complaint attributed to the hydraulic service brakes, one crash-related filing, and zero fire incidents. Contextualized against the year-by-year record, the 1990 and 1991 model years logged 8 and 9 complaints respectively — a modest upward drift in the later window — yet none of the three reporting years produced recalls, investigations, or technical service bulletins, indicating the underlying issues never escalated into systemic or safety-driven actions. The single 1977 brake-related entry sits at the very low end of this complaint spectrum, and its placement well before the higher-volume 1990–1991 period suggests the early-generation model attracted fewer owner filings overall. One caveat worth noting: the federal dataset captures only complaints filed in the years shown, so it may not fully reflect the original-era defect profile of a vehicle now nearly five decades old, and a hands-on pre-purchase inspection remains essential. The takeaway: based strictly on the available record, the 1977 Marquis is a low-complaint, no-recall year and a defensible candidate to buy, provided its age-related mechanical condition is verified independently.

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… Remedy: DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE TRANSMISSION SHIFT CONTROL INSERT, WITHOUT CHARGE TO OWNER.
