The Good
The 1986 Suburban boasts rugged reliability, thanks to its robust body-on-frame construction and durable V8 engines. Its immense interior space offers practical comfort for large families, while the classic, imposing design evokes a sense of nostalgia and strength. It provides strong towing performance and surprising long-term value for a vintage utility vehicle, appealing to both those seeking a practical hauler and emotional connection to American automotive history.
The Bad
Known weaknesses for the 1986 Chevrolet Suburban include significant fuel inefficiency, especially with carbureted V8s. Rust is a common issue, particularly on rocker panels, wheel arches, and tailgate. Brake performance can be underwhelming for such a large vehicle, and the steering can feel vague. Interior plastics and trim also show their age, with potential for cracking or fading over time.
1986 Chevrolet Suburban: Quick Overview
- Engine Options: The 1986 Chevrolet Suburban offered a range of robust engines.
- 5.0L (305 cu in) V8 (LO3): Carbureted, typically around 160 hp.
- 5.7L (350 cu in) V8 (L05): Carbureted, usually around 165-170 hp. This was a very common and popular choice for its balance of power and durability.
- 7.4L (454 cu in) V8 (L19): Carbureted, offering significantly more power, often in the range of 230-240 hp, ideal for heavy towing.
- 6.2L (379 cu in) Diesel V8 (Detroit Diesel J-code): Naturally aspirated, producing around 130-140 hp and strong torque, known for better fuel economy than the gasoline V8s.
- Horsepower: Ranged from approximately 130 hp (6.2L Diesel) to 240 hp (7.4L V8).
- Fuel Economy: This was not a strong suit.
- Gasoline V8s: Typically in the range of 8-12 MPG city, 12-16 MPG highway, heavily dependent on engine, gearing, and driving style.
- 6.2L Diesel: Could achieve better, around 15-18 MPG city, 18-22 MPG highway.
- 0-60 mph Times: Performance was leisurely by modern standards.
- Gasoline V8s: Generally 12-15 seconds, depending on engine and configuration.
- Diesel: Closer to 15-18 seconds.
- Towing Capacity: A major selling point.
- Depending on engine, gearing, and hitch setup, towing capacity could range from 5,000 lbs to upwards of 9,500 lbs (with the 454 V8 and appropriate heavy-duty equipment).
- Trim-Level Features:
- Custom Deluxe (Base): Basic vinyl or cloth seating, rubber floor mats, manual windows and locks, AM radio. Functional and no-frills.
- Scottsdale: Stepped up with more comfortable cloth interiors, carpeting, color-keyed dash, and sometimes optional power windows/locks, air conditioning.
- Silverado (Top Trim): Luxurious for its time, featuring upgraded cloth or optional velour upholstery, full carpeting, chrome trim, power windows, power locks, tilt steering, cruise control, improved sound system (AM/FM stereo cassette), full gauge package, and often more extensive exterior brightwork. Many desirable options like rear AC, heavy-duty cooling, and towing packages were frequently added to Silverado models.

Analysis
What Problems Does the 1986 Chevrolet Suburban Have?
Rust: This is arguably the most pervasive issue. Owners commonly report rust in the rocker panels, wheel wells, tailgate (especially around the glass and hinges), door bottoms, and floorboards. Frame rust can also be a concern in salt-belt regions.
Fuel System Issues: With carbureted gasoline engines, problems like clogged carburetors, fuel pump failures (mechanical pumps are common), and deteriorated fuel lines are not uncommon after decades of service. Vapor lock can sometimes be an issue in hot weather.
Braking System: The stock braking system, often front disc/rear drum, can feel inadequate for the vehicle's size and weight, especially when towing. Owners frequently report soft pedal feel, extended stopping distances, and premature wear of components.
Steering Components: Worn steering components such as tie rods, drag links, and steering box play can lead to vague steering, wandering, and excessive play in the steering wheel. Power steering pump leaks are also common.
Transmission Concerns: While generally robust, the automatic transmissions (like the TH400 or 700R4) can develop issues with age, including delayed shifts, slipping, or outright failure if not properly maintained. The 700R4, in particular, benefits from regular fluid and filter changes and can be sensitive to hard usage.
Electrical Gremlins: Age can bring about electrical issues, from failing window motors and dashboard gauges to intermittent lighting problems and charging system concerns (alternator/voltage regulator). Vacuum leaks are also common and can affect various systems.
HVAC System: Air conditioning systems often require R12 to R134a conversions, and older components like compressors, condensers, and evaporators can fail. Heater cores can also leak.
Recalls: For a vehicle of this age, specific recalls for the 1986 model year might be limited or already addressed. However, general safety campaigns related to fuel tanks or braking systems could have applied to the broader 7th generation. It's always advisable to check NHTSA records for any open recalls by VIN for specific vehicles.

How Does the 1986 Chevrolet Suburban Compare to Other Sport Utility Vehicle?
Performance: The Suburban's range of V8 engines, particularly the 454 big block, often gave it an edge in raw towing capacity and power over many rivals, especially the Bronco. Its longer wheelbase provided a more stable ride, crucial for hauling. Ford's 302 and 351 V8s in the Bronco were capable but couldn't match the 454's brute strength.
Features: The Suburban, particularly in Silverado trim, offered comparable or slightly better comfort and convenience features like power windows, locks, and air conditioning to its contemporary rivals. Its unique selling proposition was the third row seating and massive interior volume, which few rivals could truly match in a passenger configuration. The Ford Bronco was a two-door, while the Ramcharger was also typically a two-door, limiting direct comparison in passenger capacity.
Reliability: All three brands had a reputation for robust, if not refined, engineering in this era. The Suburban's conventional V8s and transmissions (like the TH400) are known for exceptional longevity if maintained. Ford's engines (302, 351) were also durable. Reliability largely came down to owner maintenance for all these vehicles.
Price: New prices were competitive across the board, with minor variations based on trim and options. Today, the Suburban often holds its value better, especially 4x4 models, due to its iconic status and utility.
Recommended Alternatives:
If seeking a similar full-size, utilitarian classic:
- Ford E-Series Club Wagon (circa 1980s): While a van, it offered similar passenger and cargo capacity with V8 power and often more robust interior space for truly large families or commercial use. Less "SUV" feel but highly practical.
- International Harvester Travelall (earlier models, up to 1975): For a truly vintage alternative, the Travelall was the Suburban's original direct rival, offering similar multi-door, multi-passenger utility, but from an earlier generation.
- Later model Suburbans (8th generation 1992-1999): If you want the Suburban utility with slightly more modern amenities (EFI, ABS, improved interiors) without going fully modern, these are excellent alternatives that are still relatively affordable.
