The original problem was identified in August and fixed. Approximately 3-4 weeks later I was getting a signal "check engine". I took the car in waiting to see what might be wrong this time. Doug explained that the part was faulty if I remember correctly which ironically was the same part that was fixed 3-4 weeks before. In the end everything is I hope back to normal as normal as can be with a 2008 Forester. I appreciate the diligence and professional courtesy in the handling of this situation by Doug, his staff/mechanics and Parra Car Care of Euless.
