What Problems Does the 2003 Lexus GS Have?
Frequently reported problems for the 2003 Lexus GS often revolve around age-related wear and tear. Oxygen sensor failures are common, leading to decreased fuel economy and potential catalytic converter damage. The navigation system, if equipped, can become outdated and prone to malfunctions. Suspension components, particularly bushings, may wear out, resulting in a less comfortable ride and reduced handling precision. Oil leaks, especially from the valve cover gaskets and rear main seal, are another recurring issue. Electrical problems, such as malfunctioning power windows or door locks, can also occur. Lexus has issued recalls for GS models in the past, but specific recalls for the 2003 model year should be checked on the NHTSA website using the VIN. Long-term reliability is generally good, but these issues should be addressed to maintain the car's performance and longevity. The GS 430, with its more powerful V8, may experience slightly higher maintenance costs due to increased stress on components. Some owners have also reported issues with the transmission shifting smoothly as the car ages. Regular maintenance is crucial to mitigate these problems.
How long will the 2003 Lexus GS last?
A well-maintained 2003 Lexus GS can easily exceed 250,000 miles or provide 20+ years of service. With diligent maintenance, including regular oil changes, timely replacement of wear items, and addressing issues promptly, these cars are known for their longevity. However, neglecting maintenance can significantly shorten their lifespan. Long-term weaknesses often involve rubber components (hoses, bushings) drying out and cracking, leading to leaks and suspension issues. Electrical components can also become problematic over time. The key to long-term durability is consistent and preventative maintenance.
What Technology & Safety Features are Included?
The 2003 Lexus GS features a decent array of built-in tech for its time. Standard features include a premium sound system with a cassette player and CD player (later models included a multi-disc CD changer), automatic climate control, and power-adjustable seats. Optional features included a navigation system (which now appears dated), a Mark Levinson premium sound system upgrade, and heated seats. Driver-assistance features were limited compared to modern cars, but included Vehicle Stability Control (VSC) and Traction Control (TRAC). Safety features comprised anti-lock brakes (ABS), front and side airbags, and seatbelt pretensioners.
Crash-test ratings from the NHTSA and IIHS were generally favorable for the 2003 Lexus GS. NHTSA gave it high marks in frontal and side impact tests. The IIHS ratings should be checked for the specific model year. While it lacks modern driver-assistance features like adaptive cruise control or lane departure warning, its safety features were competitive for its era. The optional navigation system, while advanced for its time, is now significantly less useful due to outdated maps and limited functionality. The Mark Levinson sound system remains a highlight for audiophiles, providing exceptional sound quality. Overall, the 2003 Lexus GS offered a comfortable and safe driving experience with a respectable level of technology for its age.

How Does the 2003 Lexus GS Compare to Other Sedan?
The 2003 Lexus GS competed against the BMW 5 Series (E39), Mercedes-Benz E-Class (W211), and Acura TL. In terms of reliability, the Lexus GS typically outperforms the German rivals, offering lower long-term maintenance costs. The BMW 5 Series offered sharper handling, while the Mercedes-Benz E-Class prioritized comfort. Feature-wise, the GS was competitive, although the German cars often had more advanced technology options (at a higher price). The Acura TL provided a similar blend of luxury and reliability at a lower price point, but with less prestige.
For performance, the GS 430 was comparable to the V8 versions of its rivals. The GS 300 was adequate but not as sporty. Price-wise, the Lexus GS generally held its value well.
Alternatives to consider include the Acura TL (for value), the Infiniti M45 (for performance), and the Lexus ES 300/330 (for a more comfortable and reliable, albeit less sporty, Lexus experience). If handling is a priority, the BMW 5 Series is a better choice, but be prepared for potentially higher maintenance costs.

Final Verdict: Is the 2003 Lexus GS a Good Sedan?
The 2003 Lexus GS is ideal for buyers seeking a comfortable, reliable, and reasonably priced luxury sedan. It's a good choice for those who prioritize dependability and a smooth ride over ultimate performance or the latest technology. It is definitely worth buying *used*, especially if you can find one with a well-documented maintenance history and low mileage. The GS 430 offers more power, but the GS 300 is still a solid choice. A pre-purchase inspection by a trusted mechanic is highly recommended to identify any potential issues before committing to the purchase. Avoid models with excessive rust or signs of neglect.
