I was driving in the freeway nearby San Jose, CA with my family in the car. I was doing 67mph. It was high elevation curvy road. I experienced engine stalling. The car suddenly stop accelarating and speed drop to 35mph despite pressing on gas.

When I accelerate the car jerks as if is going to cut off. I have taken it to the dealer, and they can not find any thing wrong. After searching the internet, I find I am not the only one with this issue. I just want my car fixed so that I feel safe driving it.
