On three separate days, i had trouble stopping my brand new infiniti m35. the first day, on four occasions when i applied the brakes, the car bucked and shook and continued to go forward before finally stopping. on the second and third days, this occurred twice each day. several people saw this happening and screemed for me to put the car into neutral or turn off the motor. i took the car to the infiniti dealer three times for this problem. checked the computer read out, road tested the vehicle for 70 miles, and inspected it thoroughly but could not duplicate the problem. my friend tried twice to apply the brake and accelerator pedal simultaneously but could not duplicate the problem that i had. on each occasion, i was scared to death and was shaking and sweating. i am afraid that i will be killed in this car due to a malfunction that can not be diagnosed. if anyone else has had a similar problem, please report it so that infiniti will know that they have a serious, intermittent problem with the m35 that might end up by killing people. *dt
