What Problems Does the 1984 Mercury Cougar Have?
The 1984 Mercury Cougar, being a product of its era, has several commonly reported issues that prospective buyers and current owners should be aware of. One of the most prevalent concerns is related to rust. Due to the materials and undercoating used in the 1980s, Cougars are susceptible to corrosion, particularly in regions with harsh winters and road salt. Areas to inspect closely include the rocker panels, lower door edges, rear wheel arches, and the frame rails. Severe rust can compromise structural integrity.
Another frequent problem area involves the electrical system. Many owners report issues with power windows and locks becoming slow or inoperable. The power antenna, if equipped, can also seize up. The dashboard instrumentation, including gauges and warning lights, may develop intermittent problems or fail entirely. The air conditioning system, common in these cars, can also be a source of frustration with leaky seals and compressor failures.
The powertrain, while generally robust, can also experience age-related wear. The 3.8L V6 engine is known for potential intake manifold gasket leaks, which can lead to coolant loss and overheating. The automatic transmissions, particularly the C-5, can develop issues with slipping or delayed engagement if not properly maintained. The 2.3L turbocharged engine, while offering more performance, can be more sensitive to maintenance and may suffer from turbocharger wear or boost leaks if neglected.
Regarding recalls, specific to the 1984 model year, a search of NHTSA records indicates some recalls were issued. For instance, some models may have had issues related to the steering column or braking system. However, the majority of issues encountered today are due to the age and wear of the vehicle rather than specific manufacturing defects from that year.
Long-term reliability is heavily dependent on the vehicle's maintenance history and the climate it has resided in. Cougars that have been garaged, regularly serviced, and not subjected to extreme environmental conditions tend to hold up better. However, as with any car of this vintage, expect to encounter and address age-related wear and tear, especially in the aforementioned areas.

How long will the 1984 Mercury Cougar last?
Based on owner data and maintenance habits, a well-maintained 1984 Mercury Cougar can reasonably expect to reach 150,000 to 200,000 miles, or even more, in terms of service life. However, this is highly contingent on consistent care. The durability of the 3.8L V6 engine and the overall chassis is quite good, lending itself to longevity. Weaknesses over time primarily manifest as age-related issues: corrosion on the body and undercarriage, wear on rubber components (hoses, seals, bushings), and potential failure of aging electrical parts. Cars in rust-belt regions may struggle to reach higher mileage without significant restoration due to body deterioration. Those in drier climates and with regular fluid changes and preventative maintenance can offer decades of enjoyable service.
What Technology & Safety Features are Included?
The 1984 Mercury Cougar, as a product of its time, offered a relatively modest suite of technological and safety features by modern standards, focusing on comfort and convenience for its personal luxury coupe segment.
Entertainment: Standard entertainment typically included an AM/FM radio, often with a cassette player. Optional upgrades could involve a premium sound system with more speakers, offering a richer audio experience for the era. Power antennas were common options that added a touch of convenience.
Built-in Tech & Convenience: The Cougar emphasized comfort and ease of use. Standard features often included power steering and power brakes, making it easy to maneuver. Power windows and power door locks were common on higher trims like the LS and XR-7, or available as options on the base model. Cruise control was another popular optional feature, enhancing highway driving comfort. Climate control, while basic, was standard, with options for more advanced automatic temperature control systems on some trims.
Driver-Assistance: Driver-assistance features were virtually non-existent by today's standards. The focus was on mechanical aids rather than electronic ones. Features like tilt steering columns were available to enhance driver ergonomics.
Safety Features: Standard safety features for 1984 included seat belts (lap and shoulder belts for front occupants), padded dashboards and interiors, and an energy-absorbing steering column. The car's unibody construction was designed to provide some structural integrity. Antilock brakes (ABS) were not a common or widely available feature on vehicles of this class in 1984, and thus not typically found on the Cougar.
Crash-Test Ratings: Official crash-test ratings from agencies like the NHTSA for specific model years in the mid-1980s are not as readily available or as standardized as they are today. However, vehicles of this era generally performed less favorably in frontal and side impact tests compared to modern vehicles, primarily due to less advanced safety engineering, restraint systems, and structural design. The Cougar, like its contemporaries, would be expected to offer limited protection in severe collisions by today's benchmark.
