Is the 2004 Toyota Highlander reliable?

Yes, it’s generally considered reliable for its class and era, especially when maintenance records are solid, but high-mileage examples can develop transmission, sensor, and suspension wear issues.

What are the most common 2004 Toyota Highlander problems?

Owners most often report transmission shifting concerns (notably on some V6 models), check engine lights from oxygen sensors, suspension clunks from worn links/bushings, and age-related cooling or gasket seepage.

Are maintenance costs high for a 2004 Highlander?

Maintenance is typically moderate; parts are widely available and many repairs are straightforward, but budgeting for tires, brakes, suspension refreshes, and occasional sensor replacements is realistic on a 20+ year old SUV.

What are the best years of the first-generation Highlander to buy?

Many shoppers target later first-gen years for incremental refinements, but condition and service history matter more than the exact year; a well-maintained example is usually the best buy.

What should I check before buying a 2004 Toyota Highlander?

Verify transmission behavior on a long test drive, scan for stored codes, inspect coolant condition and radiator/hoses, check for suspension noise and uneven tire wear, and review records for timing-related services, fluid changes, and major repairs. For full specs, trim details, fluid capacities, and the complete maintenance schedule, get a complete owner’s guide and shop with confidence.

Top Risk Areas

The systems that tend to fail first on the 2004 Toyota Highlander, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.

Power Steering Systemmoderate~80,000-120,000 mi

The power steering pump and associated lines are prone to developing leaks or developing a 'whining' noise, especially as the vehicle ages and mileage accumulates. This can lead to fluid loss and increased steering effort if not addressed.

Suspension Componentsmoderate~90,000-150,000 mi

Like most vehicles of this vintage, struts, sway bar links, and various bushings (especially lower control arm bushings) will wear out, leading to clunking noises, reduced ride comfort, and potentially uneven tire wear. Rear subframe rus…

Radiator End Tanksmoderate~100,000-160,000 mi

The plastic end tanks on the radiator are susceptible to cracking and leaking over time due to repeated heat cycles and material degradation. This can lead to coolant loss and engine overheating if not caught early.

Full repair-cost ranges, fix-before-you-buy notes, and inspection checklists are in the report.

2004 Toyota Highlander Mileage Danger Zones

The mileage windows when the 2004 Toyota Highlander most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

30,000

Low Risk Zone

At this mileage, the Highlander is still very new. Focus on routine oil changes, tire rotations, and general fluid checks to set a good foundation for long-term reliability.

60,000

Maintenance Zone

Key fluid services are due, including transmission fluid (especially if towing), coolant, and power steering fluid. This is also a good time for a thorough inspection of tires, brakes, and suspension components.

90,000

Elevated Risk Zone

This mileage brings the critical timing belt replacement for V6 models. Also, expect to address initial signs of wear in suspension components and potential power steering leaks. Neglecting these can lead to more costly failures.

120,000+

High Risk Zone

Beyond 120,000 miles, the Highlander will demand attention to age-related wear and tear. Radiator issues, further suspension overhaul, and potential electrical gremlins become more likely. Maintenance history becomes paramount for high-m…
