Analysis

What Problems Does the 2004 Lexus GS Have?

Frequently reported problems for the 2004 Lexus GS often revolve around age-related wear and tear. These include: Issues with the automatic transmission, particularly rough shifting or failure, especially in higher mileage examples. Suspension components, like ball joints and bushings, are prone to wear, leading to noises and degraded handling. Oil leaks, particularly from valve cover gaskets and sometimes the rear main seal, are common. The navigation system, if equipped, can become outdated and difficult to update.
Other potential issues include: Power steering pump leaks and failures. The air conditioning system may require servicing over time. The oxygen sensors can fail, triggering a check engine light. Some owners have reported issues with the instrument cluster.
While Lexus is generally reliable, the 2004 model year is susceptible to problems common in older vehicles. Recalls for this specific year are relatively few, but it's always best to check the NHTSA website for the most up-to-date recall information. Long-term reliability depends heavily on maintenance history; well-maintained examples will likely fare better. Overall, preventative maintenance is key to avoiding major problems.

How long will the 2004 Lexus GS last?

With good maintenance, a 2004 Lexus GS can easily reach 250,000 miles or more. Many owners report exceeding 300,000 miles. Years of service can stretch beyond 20 years with diligent care. Long-term durability is generally strong, a hallmark of Lexus vehicles.
However, weaknesses appear over time. Rubber components like hoses, belts, and bushings degrade. Electronic components can fail due to age and heat. Rust can become a concern in regions with harsh winters and road salt. Maintaining fluid changes, addressing minor repairs promptly, and garaging the vehicle when possible can significantly extend its lifespan.

What Technology & Safety Features are Included?

The 2004 Lexus GS offered a decent array of tech and features for its time. Standard features included automatic climate control, a premium sound system (often Pioneer), power seats, and leather upholstery. Entertainment options centered around the sound system, which could be upgraded to a Mark Levinson system.
Driver-assistance features were limited compared to modern cars, but included Vehicle Stability Control (VSC), Traction Control (TRAC), and anti-lock brakes (ABS). Optional features included a navigation system (which now appears quite dated), a sunroof, and heated seats.
Safety features included front and side airbags.
Crash-test ratings from the IIHS and NHTSA are available for this model year. The Lexus GS generally performed well in crash tests, earning good marks for occupant protection. However, it is essential to remember that crash-test standards have evolved significantly since 2004, and newer vehicles offer enhanced safety technologies and structural designs. Overall, the 2004 GS offers a comfortable and safe experience for its era, but lacks the advanced tech and driver-assistance systems found in contemporary vehicles.

2004 Lexus GS Prices and Market Value

When new, the 2004 Lexus GS ranged from around $40,000 to $50,000 depending on the trim and options. Today, used market prices typically range from $4,000 to $10,000, depending on condition, mileage, and location.
Depreciation has been significant, as expected for a vehicle of this age. Resale value is primarily affected by condition, mileage, maintenance records, and geographic location. Cars in excellent condition with documented maintenance history fetch higher prices. The presence of desirable options (like the Mark Levinson audio system) can also positively impact resale value. High mileage and deferred maintenance significantly decrease value.

2004 Lexus GS Cost of Ownership

Insurance costs for a 2004 Lexus GS are moderate, generally lower than newer luxury vehicles. Fuel costs are average for its class, leaning towards the higher side with the GS 430's V8. Maintenance can be moderate if preventative care is followed. However, repairs can be costly, especially for Lexus-specific parts and labor. Overall, long-term ownership costs can be moderate to high depending on the vehicle's condition and how well it has been maintained. It's not the most economical choice, but not excessively costly either.

2004 Lexus GS Insurance

Insurance for a 2004 Lexus GS is moderately priced, reflecting its status as a Sedan with strong safety ratings and
reasonable repair costs.

How Does the 2004 Lexus GS Compare to Other Sedan?

The 2004 Lexus GS competed with the BMW 5 Series (E39/E60), Mercedes-Benz E-Class (W211), and Acura TL. In terms of reliability, the Lexus GS generally surpasses the BMW and Mercedes-Benz, known for their higher maintenance costs. The Acura TL offers similar reliability at a slightly lower price point, but lacks the GS's rear-wheel-drive dynamics and V8 option.
In terms of performance, the GS 430 offers comparable acceleration to its rivals' V8 models. Features are similar across the board, although the German rivals often had more advanced technology available as options. Price-wise, the GS falls in the middle of the pack.
Alternatives to consider include:
* Acura TL: More affordable, similar reliability, but less sporty.
* Infiniti G35: Sportier handling, similar price, but potentially less reliable.
* Later model Lexus ES: More comfortable and reliable, but less sporty.
If reliability is a top priority and you desire a luxury sedan with a sporty edge, the 2004 Lexus GS is a strong contender. However, if you prioritize cutting-edge technology, a newer vehicle might be a better choice.

The 2004 Lexus GS is ideal for buyers seeking a reliable and comfortable luxury sedan on a budget. It's worth buying *used* if you prioritize Lexus's reputation for dependability and enjoy a blend of luxury and subtle performance. The GS 430 offers a more engaging driving experience thanks to its V8 engine. It is most worthwhile if purchased with a well-documented maintenance history and a thorough pre-purchase inspection. Be prepared for age-related repairs. If advanced technology is a must-have, look elsewhere. For those prioritizing reliability and value in a used luxury car, the 2004 Lexus GS remains a solid option.
