The 2004 Lexus LS reliability record is generally strong, but age, mileage, and maintenance history matter. Here are common 2004 Lexus LS problems and issues owners report: - Suspension wear and ride quality changes (often 100,000–180,000 miles): Front control arm bushings, ball joints, and tie rod ends can wear, leading to clunks over bumps, vibration, or uneven tire wear. If equipped with adjustable/air components (varies by package and prior owner modifications), leaks or weak dampers can also cause a floaty ride. - Brake actuator/ABS-related concerns (typically higher mileage): Some owners report ABS/VSC warning lights and a brake system that behaves inconsistently. This can be related to sensors, wiring, or hydraulic/actuator components; proper diagnosis is important because parts can be expensive. - Oil leaks and seepage with age (often 120,000+ miles): Valve cover gaskets and other seals can seep, leading to burning oil smells or minor drips. These are common aging issues rather than catastrophic failures, but they should be addressed to avoid bigger messes and rubber degradation. - Electronics and convenience features aging out (varies widely): Power seat functions, door lock actuators, window regulators, and climate control components can fail after years of use. These are typical luxury-sedan “common issues” where repair cost depends on parts availability and labor.
