On the 2000-2003 Lexus RX 3.0L 1MZ-FE V6, early first-generation RX300 models are well known for premature automatic transmission failure, especially on AWD vehicles but also on FWD examples. Owners report delayed engagement into Drive or Reverse, harsh shifting, slipping on acceleration, and eventual loss of movement; teardown reports commonly cite burned clutches and damaged planetary gear components. The issue is widely documented in owner communities, repair databases, and NHTSA complaints, and is often attributed to a transmission that runs hot and is heavily stressed by vehicle weight.

This issue also affects: Toyota Corolla, Toyota Sienna, Toyota RAV4

Common Symptoms

  • Delayed engagement into Drive or Reverse
  • Harsh 1-2 or 2-3 shifts
  • Transmission slipping under load
  • Engine revs increase with little vehicle movement
  • Burnt transmission fluid smell
  • Vehicle eventually will not move

How to Fix

Diagnosis usually starts with checking fluid condition, line pressure behavior, and whether engagement delay or flare shifts are present when warm. In most cases, fluid changes do not cure an already failing unit; the durable fix is a quality rebuild or replacement transmission, often with updated hard parts and careful inspection of the cooler and valve body. Many owners also add an auxiliary transmission cooler after replacement to reduce repeat failures.

Owner tips & cautions

  • TipIf replacing the transmission, owners commonly recommend installing an external transmission cooler and fully flushing cooler lines to avoid contaminating the rebuilt unit.
  • TipUse Toyota Type T-IV compatible fluid and avoid generic fluid mixes on these early Aisin units.
Typical repair cost:$2,800 - $5,000

On the 2000-2006 Lexus RX, both RX300 and RX330 generations commonly develop power steering fluid leaks, especially from the high-pressure hose and related line connections. Owners report red fluid on the driveway, groaning or whining while turning, and heavier steering effort as fluid level drops. If ignored, the pump can run dry and fail, increasing repair cost significantly.

Common Symptoms

  • Power steering fluid leak
  • Whining or groaning when turning
  • Heavy steering effort
  • Low fluid level in reservoir
  • Fluid on driveway or under engine cradle

How to Fix

Inspect the pressure hose, return lines, reservoir, and pump area for wetness, then confirm whether the leak is from the crimped hose section or a fitting. Replace the leaking hose or line assembly, refill with the correct fluid, and bleed the system fully; if the pump has been noisy for long, inspect for internal damage. Cleaning the subframe and alternator area is important because leaked fluid can spread widely.

Owner tips & cautions

  • TipOwners recommend replacing aging return hoses at the same time as the pressure hose if they are soft or sweating, since labor overlap is significant.
  • TipAfter repair, bleed the steering system with the front wheels raised to reduce pump cavitation noise.
