Lexus GS 300: A Comprehensive Guide

The Lexus GS 300 is a mid-size luxury sedan produced by Lexus, the luxury vehicle division of Toyota, from 1993 to 2006. Positioned between the ES (Executive Sedan) and the LS (Luxury Sedan), the GS 300 offered a sportier driving experience and sharper styling than its more comfort-oriented siblings. Initially conceived as a more performance-focused alternative to European rivals like the BMW 5-Series and Mercedes-Benz E-Class, the GS 300 blended Japanese reliability with a touch of European handling, making it a popular choice for discerning buyers.

Generations

First Generation (1993-1997): JZS147

The first-generation GS 300, internally designated JZS147, was introduced in 1993. It featured a distinctive design penned by Italdesign Giugiaro, known for its sleek profile and aerodynamic shape. Key features included:

  • 3.0-liter 2JZ-GE inline-six engine producing approximately 220 horsepower.
  • Rear-wheel drive configuration.
  • Available with a 4-speed automatic transmission.
  • Luxurious interior appointments including leather upholstery, wood trim, and premium audio systems.
  • Double wishbone suspension for a comfortable yet controlled ride.

Second Generation (1998-2005): JZS160/UZS160

The second-generation GS 300, launched in 1998, brought significant improvements in design, performance, and technology. This generation had two engine configurations depending on the market.

  • The 2JZ-GE engine was carried over, and in some markets, refined for improved efficiency.
  • Available with a 5-speed automatic transmission.
  • More aggressive styling with a bolder front fascia and sharper lines.
  • Enhanced safety features including Vehicle Stability Control (VSC) and traction control.
  • Improved interior with updated materials and a more modern dashboard layout.

Important Note: Starting from 2001, Lexus introduced the GS 430, which had a 4.3-liter V8 engine. While this is not a GS 300, it shares the same chassis and interior design, making some parts interchangeable. Also worth noting that the GS 430 provides substantially improved power.

Reliability & Common Issues

The Lexus GS 300 is generally regarded as a highly reliable vehicle, a reputation built upon Toyota's renowned engineering and build quality. However, like any car, certain issues can arise over time, particularly with older models.

Common Issues (Applicable to both generations):

  • Oil Leaks: The 2JZ-GE engine is prone to oil leaks, particularly from the valve cover gaskets, timing cover seal, and rear main seal. Regular inspection and prompt repairs are crucial to prevent oil starvation and engine damage.
  • Cooling System Problems: Overheating can occur due to radiator leaks, water pump failure, or a faulty thermostat. Regular coolant flushes and inspections are recommended.
  • Suspension Components: The suspension bushings and ball joints can wear out over time, leading to clunking noises and reduced handling performance. Replacement is necessary to maintain ride quality and safety.
  • Automatic Transmission Issues: While generally reliable, the automatic transmission can experience slipping or harsh shifting, especially in older models. Regular fluid changes are essential.
  • Electrical Problems: Issues with the power windows, door locks, and climate control system can occur due to faulty wiring or components.
  • Oxygen Sensors: The oxygen sensors can fail, leading to poor fuel economy and emissions.

First Generation Specific Concerns:

  • Dashboard Cracking: The dashboard of the first-generation GS 300 is prone to cracking due to prolonged exposure to sunlight.
  • Power Antenna Malfunction: The power antenna can become stuck or fail to retract fully.

Second Generation Specific Concerns:

  • VVT-i System: While generally reliable, the VVT-i (Variable Valve Timing with Intelligence) system can sometimes experience issues with the oil control valve (OCV), leading to rough idling and reduced performance.
  • Navigation Screen Failure: Models equipped with the navigation system may experience screen failure due to age and wear.

Maintenance is Key: Regular maintenance, including oil changes, fluid flushes, and inspections, is essential to prolonging the life of the GS 300 and preventing major problems. Consult the owner's manual for recommended service intervals.

Driving Experience

The Lexus GS 300 offers a blend of comfort, luxury, and a touch of sportiness. The driving experience varies depending on the generation and specific model, but some general characteristics apply.

Pros:

  • Smooth and Refined Ride: The GS 300 provides a comfortable and quiet ride, absorbing bumps and imperfections in the road with ease.
  • Responsive Handling: The GS 300 handles well for a mid-size luxury sedan, with precise steering and minimal body roll.
  • Adequate Power: The 2JZ-GE engine provides ample power for everyday driving, though it may feel a bit lacking compared to more powerful engines.
  • Luxurious Interior: The interior is well-appointed with high-quality materials and comfortable seats.
  • Reliability: The GS 300 is known for its reliability and longevity.

Cons:

  • Fuel Economy: Fuel economy is not a strong point, especially with the older models.
  • Outdated Technology: Compared to modern cars, the technology in the GS 300 can feel dated.
  • Some Maintenance Costs: While reliable, repairs can be costly due to the car's luxury nature and potentially more complex parts.
  • Can Feel Heavy: Especially the second-generation models, they can feel a bit heavy around tight corners.

Buying Advice

If you're considering buying a used Lexus GS 300, here's some advice to help you make an informed decision:

What Years to Look For:

  • 1998-2005 (Second Generation): The second generation offers improved styling, safety features, and technology compared to the first generation. Models from 2001 onwards also benefit from further refinements.
  • Low Mileage, Well-Maintained Examples: Prioritize finding a GS 300 that has been well-maintained with regular service records. Lower mileage is generally preferable, but a car with higher mileage that has been properly cared for can be a better choice than one with low mileage but neglected maintenance.

What to Avoid:

  • Models with Significant Rust: Check for rust, especially underneath the car and around the wheel wells. Rust repair can be expensive.
  • Cars with Major Mechanical Issues: Avoid cars with obvious mechanical problems, such as engine knocking, transmission slipping, or significant fluid leaks.
  • Vehicles with a Salvage Title: Vehicles with a salvage or rebuilt title may have hidden damage and should be avoided unless you are an experienced mechanic.
  • High Mileage, Poorly Maintained Examples: Avoid examples that show signs of neglect.

Pre-Purchase Inspection:

Before buying any used GS 300, it's highly recommended to have it inspected by a qualified mechanic. The mechanic can check for potential problems and provide an estimate of any necessary repairs. A compression test can be performed on the engine to check the health of the cylinders. Check the condition of bushings and suspension components. Also, verify that all electronics and features are working properly, from the radio to the windows and the seat adjustments. Pay close attention to the transmission. A professional mechanic's assessment could save you from buying a car with hidden problems and costly repairs.

By following these guidelines, you can increase your chances of finding a reliable and enjoyable Lexus GS 300.
