The 2004 Lexus RX330 is a luxury SUV known for its comfortable ride, reliability, and upscale interior. It’s powered by a 3.3-liter V6 engine producing 230 horsepower and 242 lb-ft of torque, paired with a 5-speed automatic transmission. Owners often praise the RX330 for its smooth and quiet operation, luxurious features, and Toyota’s reputation for dependability. Common dislikes include a somewhat floaty suspension, less-than-sporty handling, and dated technology compared to newer vehicles.

Engine

3.3L 3MZ-FE V6

  • Oil Leaks
    • Description/Symptoms: Oil leaks can occur from various locations, including the valve cover gaskets, timing cover, and oil pan. Symptoms include visible oil leaks on the engine or ground, a burning oil smell, and low oil levels.
    • Solution: Replacing the leaking gaskets or seals is the typical solution.
    • Estimated Cost to Fix: $200 - $800+ depending on the location of the leak and labor costs.
    • Recalls: None Found
  • Variable Valve Timing (VVT) Issues
    • Description/Symptoms: Problems with the VVT system, specifically the VVT-i actuator, can lead to rough idling, decreased performance, and a check engine light with codes related to VVT malfunction.
    • Solution: Replacing the VVT-i actuator and potentially the oil control valve.
    • Estimated Cost to Fix: $300 - $1000+ depending on the parts and labor.
    • Recalls: None Found

Transmission

5-Speed Automatic (U151E)

  • Delayed or Harsh Shifting
    • Description/Symptoms: The U151E transmission can sometimes develop issues with delayed shifting, harsh shifts, or slipping between gears. These problems can be caused by worn-out transmission fluid, valve body issues, or internal damage.
    • Solution: Start with a transmission fluid flush. If that doesn’t resolve the issue, valve body repair or replacement, or a complete transmission rebuild or replacement may be necessary.
    • Estimated Cost to Fix: $150 (fluid flush) - $3500+ (rebuild or replacement).
    • Recalls: None Found

Suspension

  • Strut and Shock Absorber Failure
    • Description/Symptoms: Worn struts and shocks are a common issue due to the vehicle’s age and mileage. Symptoms include a bouncy or unstable ride, excessive body roll when cornering, and longer stopping distances.
    • Solution: Replacing the worn struts and shocks.
    • Estimated Cost to Fix: $400 - $1200+ for all four corners, depending on the brand and labor costs.
    • Recalls: None Found
  • Rear Air Suspension Issues (If Equipped)
    • Description/Symptoms: Some RX330 models were available with a rear air suspension system. This system can develop leaks in the air springs or compressor failure, leading to a sagging rear end or the inability to maintain proper ride height.
    • Solution: Replacing the air springs or compressor. Some owners opt to convert to a traditional coil spring suspension.
    • Estimated Cost to Fix: $500 - $1500+ for air suspension repair, $500 - $1000 for coil spring conversion.
    • Recalls: None Found

Electrical

  • Navigation Screen Failure
    • Description/Symptoms: The navigation screen can sometimes fail, displaying a blank screen or malfunctioning. This can be due to a faulty screen, a problem with the navigation computer, or wiring issues.

    • Recalls: None Found
  • Center Console Lid Latch Failure

Summary

The 2004 Lexus RX330 is generally a reliable vehicle, but like any car of this age, it is susceptible to certain common issues. Engine oil leaks and transmission problems are the most concerning, as they can be costly to repair. Suspension wear and electrical glitches are also typical maintenance items. The dashboard cracking is a well-known cosmetic issue. Overall, addressing these potential problems can range from a few hundred to several thousand dollars, depending on the severity and the required repairs. Pre-purchase inspections are crucial.
