The 1987 Buick LeSabre is a full-size, front-wheel-drive sedan (also offered as a wagon) built for comfortable everyday driving and long highway trips. It sits in Buick’s traditional “big family car” space, with a smooth ride, a roomy cabin, and straightforward mechanicals compared with many modern vehicles. This model year is part of the seventh-generation LeSabre (1986–1991), introduced with a major redesign for 1986 that moved the car to GM’s H-body front-drive platform. It’s ideal for drivers who want classic Buick comfort, a large trunk, and easy cruising manners in an affordable older sedan.

1) ENGINE OPTIONS AND RELAXED PERFORMANCE: Most 1987 LeSabres were equipped with GM’s 3.8L Buick V6, known for strong low-end torque and good longevity when maintained. Some trims/markets also offered a 3.0L V6, but the 3.8L is the powertrain most shoppers seek for durability and parts availability. 2) FRONT-WHEEL DRIVE H-BODY LAYOUT: The FWD design improves wet-weather traction and contributes to a flatter floor and generous interior space, especially for rear passengers. 3) COMFORT-FIRST TUNING: Soft suspension calibration, supportive seating, and a quiet highway character are major LeSabre selling points, especially compared with sportier sedans of the era. 4) PRACTICAL FULL-SIZE PACKAGING: A wide-opening trunk, easy entry/exit, and good outward visibility make it a user-friendly classic for commuting or weekend travel. 5) TRADITIONAL BUICK AMENITIES: Depending on trim, many examples include power windows/locks, cruise control, air conditioning, and an available bench seat for six-passenger capacity.

Owners searching “1987 Buick LeSabre reliability” often find that these cars can run a long time, but age-related failures are common. Here are several “1987 Buick LeSabre problems” and “1987 Buick LeSabre common issues” that come up frequently: 1) INTAKE/COOLANT LEAKS AND OVERHEATING RISK (COMMON ON AGED 3.8L CARS): With mileage often well over 100,000 today, coolant seepage, thermostat housing leaks, aging hoses, and radiator wear can lead to overheating if ignored. Symptoms include coolant odor, low coolant level, and temperature creep in traffic. 2) TRANSMISSION SHIFT QUALITY AND WEAR: Many 1987 LeSabres use a 4-speed automatic that can develop delayed engagement, rough shifts, or slipping as mileage climbs (often reported around 120,000–180,000+ on neglected fluid). Regular fluid service helps, but a worn unit may require rebuild work. 3) ELECTRICAL GREMLINS FROM AGE: Power window motors/regulators, dash gauges, interior lighting, and intermittent accessories can act up due to tired switches, grounds, or brittle wiring. Charging system issues (alternator/battery connections) are also common on older survivors. 4) SUSPENSION AND STEERING PLAY: Clunks over bumps, wandering at highway speed, and uneven tire wear are often tied to worn struts, tie-rod ends, ball joints, or control arm bushings. These cars ride best when the front end is tight and aligned.
