2000 Lexus LX470 traction control light comes on when making a left curve. It also locked up my right front tire on a few occasions once doing 75 down the freeway. After spending over $5000 rebuilding EVERYTHING in the front end, I got rid of the Michelin defender tires that were six ply and went to Bridgestone duellers 10ply. Problem solved. I love Michelin tires but their sidewall must be a little weak. All I know is I was ready to sell it and now I am thrilled with it again.
