While driving my manual transmission cad Ats it stalls without warning or reason. It stalls mostly when in neutral, like when sitting at a red light, or pulling into a parking place. It also stalls when in first or second gear,like when turning a corner. I am not pulling the clutch out too soon and hence stalling the car myself, it does it all by itself! the car gives no warning shake or noise, it simply is off, often without my knowing it is off. This has happened to my brand new Ats since the second day of having it, and has ever since, approximately 7 weeks now. It occurs with the gas tank full, almost empty, and in between. It occurs on flat streets, and maybe at an incline. It occurs when cold in the morning, and after hours of driving. It occurs day and night, with and without passengers. The dealer has had the car in twice to investigate, with no luck. This is ridiculous!!.
