I just brought my 2012 Subaru in for service. The car would stall as it was coming to a stop - Just under 10-15mph. the Dealer said it is a Faulty torque Converter that needs to be replaced. Is this common on a 2 year old car with 46000 miles?? Might I be suspicious they are misdiagnosing the problem?? Any advice would be welcomed. Thanks Joe
