2001 Lexus ES300

The 2001 Lexus ES300 is a mid-size luxury sedan known for its comfortable ride, reliability, and smooth operation. It was available with only one engine option: the 3.0-liter 1MZ-FE V6 engine, producing 210 horsepower and 220 lb-ft of torque. This engine was paired with a 4-speed automatic transmission. Owners often praise the car for its quiet cabin, plush ride, and Toyota-derived reliability. However, common complaints include its somewhat bland styling, lack of sporty handling compared to competitors, and the age-related issues that come with owning a vehicle of this vintage.

Engine

  • Solution: Performing a transmission fluid flush and/or replacement. In severe cases, a transmission rebuild or replacement may be necessary.
  • Estimated Cost to Fix: $100 - $250 for fluid service, $1500 - $3000+ for rebuild/replacement.
  • Recalls: None Found
• Harsh Shifting
  • Description/Symptoms: Rough or jerky shifts, especially when shifting between gears at low speeds.
  • Solution: Could be caused by dirty transmission fluid, faulty solenoids, or internal damage. Start with a fluid flush and filter replacement. If the issue persists, further diagnostics may be required.
  • Estimated Cost to Fix: $100 - $250 for fluid service, $200+ for solenoid replacement, $1500 - $3000+ for rebuild/replacement.
