Ltr fm brett woody (TX) re dangerous defective transmission software problems in the 2002-2003 Lexus Es300, reply attn Jan crow/ houston ofc. Consumer would apply more and more pressure to the brake pedal but vehicle wouldn't accelerated. The transmission failed twice. Lexus had given the consumer a new vehicle and it had similar problems. The vehicle almost had gotten the consumer into several accidents. On numerous occasions after the brake pedal was tapped, the vehicle would accelerate but the rpm's would fly up and the vehicle would barely move. In stop in go traffic the vehicle would surge forward. (this felt as if the transmission slipped then the surging occurred) there was an annoying rattle in the ceiling console.
