I have had several instances where you push the accelerator and you start to go and then it just stops moving like the transmission has disengaged. Started to turn into oncoming traffic this morning and had to stop as as it did this and I was going to get hit!!! it does it a lot, first time I would have been hit!!! gm says they know it's a problem, at shop now again for it! going to get someone killed!!!!.
