Since August of 2009, having problems with engine/transmission. Vehicle "died in flight" in August, vehicle coughs, stutters, and stalls out every day at first start-up, and I'm experiencing harsh shifting daily. I'm advised there is no resolution to the daily stall-out problem even though the vehicle has been in to the service department four times since 8/6/09. On last visit to service department I was advised that "GM is aware of the problem but has no fix for it" (case #11074714).
