I have a 2001 RX300 with 63,000 miles. For the past 2 weeks whenever I have stopped and put my foot on the accelerator to go forward, I hear a grinding noise and the car shudders. I have to take my foot off the accelerator and go forward slowly and then pick up speed. I took it to the shop and $1,000.00 later; I still have the same problem. They claimed to never hear the sound, it occurs at least once every day, the most three times. Any help would be appreciated.
Thank you.
