Subaru SVX: A Comprehensive Guide

The Subaru SVX, a grand touring coupé produced from 1991 to 1996, stands out as a daring and technologically advanced vehicle for its time. It was Subaru's attempt to move upmarket and compete with more established premium brands. While sales never reached projected numbers, the SVX has since gained a cult following due to its unique styling, advanced engineering, and relative rarity. This guide provides a comprehensive overview of the SVX, designed to inform potential buyers and enthusiasts alike.

Generations

The Subaru SVX only had one generation, although there were minor changes throughout its production run.

First Generation (1991-1996)

• Years: 1991-1996
• Key Features:
  • Giorgetto Giugiaro-designed coupé body with unique "window-within-a-window" design.
  • 3.3-liter EG33 horizontally-opposed (flat-6) engine producing 230 horsepower and 228 lb-ft of torque.
  • Standard four-speed automatic transmission (4EAT).
  • Available all-wheel drive (AWD) system (standard on most models, optional on some early US models).
  • Four-wheel independent suspension.
  • Luxury features such as leather upholstery, power windows/locks, and automatic climate control.
• Notable Changes:
  • 1992: Minor interior trim changes. Introduction of an optional touring package.
  • 1993: Minor exterior trim adjustments, including a change to the rear spoiler design on some models.
  • 1994: Introduction of a driver's side airbag. Changes to the wiring harness to improve reliability.
  • 1995: Further refinements to the wiring harness.
  • 1996: Final year of production. Limited numbers were produced, making them relatively rare.

Reliability & Common Issues

The SVX, despite its advanced engineering, has several known reliability issues that potential buyers should be aware of. Addressing these issues proactively can ensure a more enjoyable ownership experience.

Engine (EG33)

• Head Gasket Leaks: The EG33 engine is prone to head gasket leaks, especially at higher mileage. Symptoms include coolant loss, overheating, and white smoke from the exhaust. Replacement requires significant labor and can be costly. Pressure testing the cooling system is recommended during inspection.
• Oil Leaks: Oil leaks are common from various seals and gaskets, including the valve cover gaskets and the front crankshaft seal. Regular inspection and timely replacement are crucial to prevent oil starvation and engine damage.
• Timing Belt: While the EG33 engine uses a timing chain, some components associated with the timing system can wear. Listen for rattling noises, especially at startup.

Transmission (4EAT)

• Automatic Transmission Failures: The four-speed automatic transmission (4EAT) is generally reliable but can experience issues, particularly if not properly maintained. Problems include slipping gears, hard shifting, and complete transmission failure. Regular fluid changes (every 30,000 miles) are critical to prolong its lifespan. Consider a transmission cooler for added reliability, especially if you plan on spirited driving.
• Torque Bind: In AWD models, torque bind can occur due to issues with the viscous coupling. Symptoms include a shuddering or binding sensation when turning at low speeds. Replacing the viscous coupling is often necessary.

Electrical System

• Wiring Harness Degradation: The wiring harness in the SVX is known to degrade over time, leading to electrical gremlins. Issues can include intermittent electrical problems, malfunctioning sensors, and difficulty starting. Careful inspection of the wiring harness, particularly in the engine bay, is recommended. 1994-1996 models had improved wiring.
• Climate Control Issues: The climate control system can experience issues, including malfunctioning blend doors and compressor failures. Diagnosing and repairing these issues can be complex and costly.
• ABS Issues: ABS sensors and modules can fail. Replacement sensors are available, but sourcing a functioning ABS module can be challenging.

Other Common Issues

• Suspension Components: Worn suspension components, such as bushings, ball joints, and struts, are common on older vehicles. Inspect the suspension for excessive play, noises, and uneven tire wear.
• Rust: Depending on the climate, rust can be a significant issue, particularly in the wheel wells, rocker panels, and undercarriage. Thoroughly inspect the vehicle for rust before purchasing.
• Window Regulators: The unique window design can put extra strain on the window regulators, leading to failures. Replacement regulators can be difficult to find and expensive.

Driving Experience

The Subaru SVX offers a unique driving experience characterized by its smooth engine, comfortable ride, and distinctive styling.

Pros

• Smooth and Powerful Engine: The EG33 flat-6 engine provides ample power and a refined driving experience. Its smooth power delivery makes it ideal for cruising and long-distance driving.
• Comfortable Ride: The SVX offers a comfortable ride, making it well-suited for grand touring. The suspension effectively absorbs bumps and road imperfections.
• Unique Styling: The SVX's distinctive styling, including its "window-within-a-window" design, sets it apart from other cars. It is a head-turner and a conversation starter.
• All-Wheel Drive (AWD) Capability: The AWD system provides excellent traction in all weather conditions, enhancing safety and confidence.

Cons

• Automatic Transmission Only: The lack of a manual transmission option limits the car's appeal to some enthusiasts.
• Fuel Economy: Fuel economy is not a strong point, with the SVX typically achieving around 18-20 mpg in mixed driving.
• Parts Availability: Some parts for the SVX can be difficult to find and expensive, especially unique components like the window regulators and certain interior trim pieces.
• Complexity: The SVX's advanced engineering can make it more complex to diagnose and repair than simpler cars.

Buying Advice

Purchasing a Subaru SVX requires careful consideration due to its age and potential reliability issues. Here's some advice to help you find a good example:

What Years to Look For

• 1994-1996 Models: These later models generally have improved wiring harnesses and may have undergone some minor updates that enhance reliability.
• Well-Maintained Examples: Look for vehicles with documented maintenance history, demonstrating that the previous owners took good care of the car.

What to Avoid

• Vehicles with Significant Rust: Rust can be costly to repair and can compromise the structural integrity of the car.
• Vehicles with Undiagnosed Electrical Problems: Electrical issues can be difficult and expensive to resolve, so avoid cars with unresolved electrical gremlins.
• Vehicles with Transmission Problems: Transmission repairs can be costly, so avoid cars with slipping gears, hard shifting, or other transmission issues.
• Modifications: Unless tastefully done and well-documented, heavily modified SVXs might present unknown issues. Stick to stock or lightly modified examples.

Pre-Purchase Inspection Checklist

• Engine: Check for head gasket leaks, oil leaks, and any unusual noises. Perform a compression test to assess the engine's overall health.
• Transmission: Test the transmission for smooth shifting in all gears. Look for signs of slipping or hesitation.
• Electrical System: Inspect all electrical components, including the lights, windows, climate control, and ABS. Pay close attention to the wiring harness for signs of degradation.
• Suspension: Check for worn suspension components, such as bushings, ball joints, and struts. Look for uneven tire wear.
• Rust: Thoroughly inspect the vehicle for rust, particularly in the wheel wells, rocker panels, and undercarriage.
• Interior: Assess the condition of the interior, including the seats, carpets, and dashboard. Look for signs of wear and tear.
• Documentation: Review the vehicle's maintenance history to ensure that it has been properly maintained.

The Subaru SVX is a unique and rewarding car to own, but it requires careful research and attention to maintenance. By following this guide and conducting a thorough pre-purchase inspection, you can increase your chances of finding a well-maintained example that will provide years of driving enjoyment.
