I have a new 2010 Subaru Legacy Premium Edition purchased in January. I have suddenly experience a major safetly issue with the car. It seems to occur when I am downshifting from 3rd to 2nd (usually as I am turning a corner, but has happened driving straight) the car suddenly shuts off and I lose all control. Sometimes I can restart as I am driving other times I have to come to a stop to restart. It has been at the Subaru dealership since last Friday. I am only getting a "there is definitely something wrong with your car" answer. They stated they have done a compression test and now a valve test? they are awaiting a response from Subaru of America...has anyone else had this problem? Any advice, information is greatly appreciated. Thanks!
