Going around a traffic circle the back of the truck slides away and steering is problematic. It's a very disconcerting feeling. I keep hearing a knocking sound from the underside even over small bumps or rough road.

After feeling that my brakes hadn't worked properly at a stop light (I almost skid through it), I was traveling about 35 mph around a curve and lightly pressed on the brakes to make sure I would slow down. Unbelievably, my brakes completely failed and I actually believe I sped up while at the same time my steering went out of control. I was unable to control or stop the car. After a few seconds I was able to pull off to the right and mud slowed me down enough to come to a stop. It was a truly petrifying experience and the tow truck driver confirmed that my brakes were completely non-functioning when he had to use the emergency brake to get my car on his truck. Lexus claimed that they could find nothing wrong with the car, however, which I find to be extremely disturbing. I pray that they do not attempt to resell or lease this car.
