I own a 2015 wrx limited CVT. When I go to my car to go to work and I start it, the car sputters. I've only noticed this on cold starts only, once the car is warmed up it's fine. For some reason though when the car is sputtering on start ups it will trip my cel and basically put the car into 'get home' mode, but it only seems to trigger the cel when it wants to. The car will always sputter on start up but sometimes the cel will come on and I can't use the drive modes and sometimes it won't come on. No matter what I do I can't get the car to stop sputtering. I've cleaned pretty much every sensor I could and nothing worked. I scanned the obd2 port and got p0300 for random misfire, which tells me absolutely nothing.

The RPM drop and the engine stalls, but no check engine lights come on. It only happens in first gear, from what I've noticed.

In a 2015 subaru wrx with a 6-speed manual transmission purchased 03/2015 and delivered to purchase dealer 04/2015. Reported to subaru dealer 02/19/2016 a rough idle with engine rpms recorded between 400 and 1k. Rough idle tripped a check engine light after fueling and cruise control light began flashing. Diagnostic code p0420 reported a fault in catalytic converter. Software update to computer performed resolved issue temporarily. 04/10/2016 at 9.7k miles rough idle issue returned rpms of 400 to 1k again after fueling. In neutral 30-60 seconds after starting vehicle stalled at fuel station. Upon re-starting vehicle check engine, flashing cruise control, ABS, hill-start assist, and traction control faults tripped. Vehicle behavior similar to the federal safety agency recall 16v‑162 where the federal safety agency noted 'due to the use of incorrect material for a portion of the engine turbocharger air intact duct crack, the engine may develop a rough idle, reduced power, and possibly stall'. Complainant believes recall may need to be expanded to include a wider range of vins before listed production dates in recall order.
