Bought the car brand new in 2013 and have regularly noticed idle issues and stalling at times when coming to a stop. I had the dealer reflash the ECU about a year ago, but that didn't seem to solve the issue. I had an Injen intake and determined that it was causing my car to run lean. I replaced it with a Perrin CAI and also added a Borla catback. The idle issue was still noticeable at times but not as pronounced. Two weeks ago I bought an ECUTek programming kit from Perrin along with a custom map they made for my car, in hopes this would eliminate my idle issues and increase my throttle response. It ran great for the last two weeks and today the CEL and slip light came on. The first time I've had the CEL light come on since I've owned the car. It was noticeably bogged down and would downshift hard and delayed. I took it home and reflashed the ECU with my Perrin map, and the lights went away and the car ran normal again. I did some datalogging with my ECUTek to send to Perrin, and the lights came on again. I used my ECUTek to diagnose and clear the code, and it was the P0018 Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A. It went back to running fine for about a mile and then the lights popped up and the engine went limp again. This all took place today. I'm going to call Perrin on Monday and give them my datalog and see if they think it's the map or if I have to take it to the dealer. I purchased the 7 year extended warranty, so I'm hoping it shouldn't be an issue if I have to go to the dealer... Any recent news, thoughts, or suggestions on this issue would be greatly appreciated!!

This sounds identical to my issue. Subaru had my car for a month. The work order states that they reflashed the ecm several times then they road tested and the light kept returning, and that all data logs were sent to Subaru tech support for analysis. They recommended that the dealership replace the ecm, so they did and they road tested and sent the new data logs for analysis. Car has been working fine so far for 1 week.
The main thing thats sucks is that my plans for this car have changed. Before it was to wait until the 30k/3year warranty was up to then install SC. Now its more about monitor the car and watch my miles so that the 3years hit before the 30k miles. Then I'll probably get the extended 7yr warranty when it is offered. Im also considering just moving on to something else.
Side note that I want to mention is that the car feels more responsive with the new ecm and stock map. So, im not sure if I will go back to my tune, at least not for a while.
