Service brakes, March 13, 2011 - mansfield MA I purchased my 2010 Lexus Rx 450H in December 2010. Ever since I bought it, I have noticed that from time to time, when I press the brake pedal, the car seems to surge forward(!) momentarily before it slows down. This happens most frequently. It will happen even if I am only coasting and not touching the gas pedal when pressing the brake initially. It happens to me at least once or twice a week. It is somewhat disturbing. I have mentioned this to my Lexus dealer, but they have dismissed my concerns both times I brought it up. Has anyone else noticed this issue? view details
