I own a Lexus Rx400H 2006. On several occasions, the vehicle has lurched forward (I.e. accelerated) before stopping when I applied the brakes at a red light or stop sign. I went to the wilkie Lexus dealership in haverford, pa on January 31, 2013. A technician performed a test on the vehicle and reported normal braking performance. I have found similar complaints on NHTSA. Based on these similar reports, I believe my vehicle is not an isolated incident. The brake system on this model needs to be investigated. I will also file a formal complaint with Lexus. I have been lucky to not hit a pedestrian or vehicle, however, it seems as if it is only a matter of time. Others with similar incidences have not been so lucky.

I was driving the Lexus Rx400H within the city and tried to brake suddenly to avoid a failed car in my lane. I pushed really hard on the brake pedal and continued to step hard on the brake. There was no braking action whatsoever. It appeared as if pressing very hard on the brake just disabled the brake. The car continued to drive like it was on a cruise control and the incident resulted in rear-ending the car in front.
