When applying the accelerator pedal from a stop position it caused a momentary pulse before the vehicle went into motion. Vehicle had been to the dealer on numerous occasions, and they were unable to locate the problem. The consumer stated that the pause was so severe that it jerks all passengers heads. The vehicle also had transmission problems. The transmission had a harsh shift and clunk when going into reverse or drive. The transmission has been repaired.
