The car jerks forward when braking. Has slow exceleration in spurts. Then surges forward. Won’t excelerate at all in stop and go traffic. Of course this does not happen with the Master Technician at the dealership. They can’t duplicate the issue. I’m afraid to drive it.

Make sure you “ACCelerate” in spurts…😉

This sounds like a transmission issue to me. Have you checked the fluid? Has it been changed recently, or even regularly?

Can you clarify this for us?  
Are you saying that the brakes don’t work properly, or that the engine’s speed increases when you hit the brakes, or… ?
