03 ES300 owners! Listen to your car! Drive the car for 10 minutes to allow it to warm up. Find a quiet location where you can drive next to curbing, or a wall, a metal crash barrier, or almost anything that a sound coming from the car can echo off of. Now open all windows so you can hear the noise coming from outside. Accelerate from a stop slowly but firmly and continue accelerating up through 40mph. As soon as the car starts moving, you should hear a clicking/rattling sound coming from outside the vehicle. It will continue throughout the acceleration until the wind noise drowns it out. Now that you've heard the noise, can anyone tell me what's causing it? Has anyone gotten a fix from Lexus yet? What was the fix? Oh yes, I also have the famous chronic tranny hesitation problem also! Anyone have a fix for that yet?
