On about 4 occasions in the 5 weeks I have had my car, the gears have been appearing to skip. I have been stopped at lights and when I go again and press the gas it jumps a gear and lunges the car forward. This week it happened for the 4th or 5th time and this time I hit someone because they ended up stopping in front of me but my car lunged forward like it was skipping gears. It has also on a couple of occasions downgraded quickly like it was dropping two shift speeds at once.
On more then 5 occasions during normal driving with my new car on a slight (10 degree) incline at a stop sign or light will roll backwards intermittently as if the shifter was in neutral. From the time it take for me to move my right foot from the brake pedal to the accelerator pedal the car will roll back at least 4 feet until I either hit the brake again or accelerator to stop the roll. The car has 2,5 on it and this issue has gone on since I bought the car. The same problem occurs when in reverse the car will role forward on an incline.
