Overview

The 2004 Lexus LX 470 is a full-size, body-on-frame luxury SUV based on the Toyota Land Cruiser, designed for buyers who want premium comfort with serious towing and off-road capability. It sits near the top of the Lexus SUV lineup for its era, offering a quiet ride, upscale materials, and long-distance comfort in a three-row package. This model is part of the 100 Series LX generation (1998–2007), known for durability and a refined V8 powertrain. It’s ideal for families, outdoor travelers, and owners who value longevity and capability over fuel economy.

Key Features

- 4.7L V8 (2UZ-FE) with 4-speed automatic transmission: Known for smooth, low-end torque and longevity when maintained; output is commonly rated around 235 hp and 320 lb-ft in this era. - Full-time 4WD with low range and a locking center differential: A major selling point for snow, towing, and trail use, with confident traction in poor conditions. - Adjustable Height Control (AHC) hydraulic suspension: Lets the LX raise or lower ride height for clearance and easier entry; also contributes to the signature Lexus ride quality. - Three-row seating and a premium luxury cabin: Leather seating, wood trim, and a quiet, well-insulated interior make it a strong long-haul family SUV. - Strong towing and load capability: As a Land Cruiser-based platform, it’s built for heavier duty use than many luxury SUVs, appealing to owners who tow boats, campers, and utility trailers.

Common Issues & Reliability

Shoppers researching 2004 Lexus LX reliability will find that these SUVs are generally long-lasting, but age-related wear and a few costly systems can show up. Here are common 2004 Lexus LX problems owners report: - AHC suspension leaks or pump/accumulator wear: The height control system can develop fluid leaks at hydraulic lines, failing accumulators (“globes”), or a weak pump. Symptoms include a bouncy ride, uneven height, or the truck stuck at one height. Often shows up around 100,000–180,000 miles depending on climate and service history. - Brake booster/actuator issues: Some owners report a hard pedal, longer stopping distances, warning lights, or ABS/VSC concerns tied to the brake actuator/booster system. These repairs can be expensive and may occur in higher-mileage examples (often 120,000+ miles). - Steering rack or front-end wear (clunks and looseness): Tie rods, rack bushings, ball joints, and control arm bushings can wear, especially on vehicles used off-road or with larger tires. Expect increased play, uneven tire wear, or clunks over bumps around 120,000–200,000 miles. - Cooling system aging and V8 maintenance items: Radiators, hoses, and fan clutches can weaken with age, leading to overheating risk if ignored. Also, the 4.7L V8 uses a timing belt that must be replaced on schedule; missing records is a major red flag rather than a “failure,” but it’s a common ownership pain point.
