Default WRX 15 CEL/P0606/EMC Flash..Still Problems

Dear WRXers:

On July 11th I pulled to a stop sign, warm day, AC on, and when I started to pull away in first gear had a loss of power/no acceleration. I pulled over, stopped the engine, restarted, and had a CEL. CEL cleared after about 10 ignitions. Prior to CEL first gear acceleration was fast, easily burst me to 30 if I wasn't careful. Now engine maxes at 20.

Engine code read from dealer on July 15th was P06060. Engine was cleared and road tested. They said "drives fine." While this is a factually true statement, does not drive like before is also true (see acceleration note). Was persistent that issue was not resolved and after a month had field technician in the area who could reflash the engine. Which was done today. Once again, acceleration issue persists.

I asked to have the field tech road test the car with me which he did with plug in monitor on turbo feeding data to his laptop. He indicated "I don't see anything" but would forward on to Fujitsu motor rep in New Jersey to look at. Although I have indicated since 7/11 there is a performance issue no diagnostics have ever been performed on the engine by Subaru tech, including the field tech today. When I asked he said, "I wasn't aware there was a problem". As I persisted he agreed to look under the hood, said he saw nothing that looked strange.

The only other issue that I can reflect on that seems odd is within my 70 days of ownership there have been a few times that car has turned over on initial ignition. This seems strange to me with a new vehicle. However, each time, it has turned on second ignition.

Dealership rep tried to tell me it I might be a) remembering how it accelerates differently than it actually did, b) the air temperature might cause a change, c) my fuel choice might cause a difference. I'm sure I remember a, b and c were constant after CEL in early July and problem persisted.

What are the questions I should ask to try to get this problem resolved?

Greatly appreciate your thoughts.

Jerry

Problem you are running into is nothing documented before the incident and it is common that after having an issue with something you begin to really pay attention to everything the car is doing. Not saying that is the issue here but something to keep in mind.

Is there another WRX you can test drive?
Possible boost leak?
Car needs to relearn?

Sounds like they are working with you and wanting to make you happy but that can quickly change if the blame stick starts getting passed around.

Positive note is a problem is documented, you've expressed your dissatisfaction, and Subaru is wanting to work with you.

Keep us posted though.

I have kept that in mind, which is why I've asked for other riders and drivers previously of the car to give me their opinion. All agree that acceleration isn't as sudden or sharp as previous.

Is there another WRX you can test drive?
Not within a 2.5 hour radius. I've put out a call to the MT WRX group and haven't heard back if anyone closer has a personal new 15. Had same thought which was a comparison drive.

Possible boost leak?
Boost guage looks ok, data generated via test drive didn't show anything that on first face looked remarkable. Manually checked turbo connections with field tech and were unable to find anything amiss.

Car needs to relearn?
The previous driving behavior was from the first time I drove the vehicle with ~100 miles on it prior to me being in the seat. I'm not sure what the relearn process is on the vehicle. Only thing I know as 4 time SubaruWRX owner is that the 2015turbo was previously more present/sharper at lower gears. It actually took a while to get use to, because acceleration in 1st gear would tend to pull the car away from you.

Sounds like they are working with you and wanting to make you happy but that can quickly change if the blame stick starts getting passed around.

I hear what you are saying, I'd just point out that it's a new vehicle under warranty with less then 1400 miles on it. The challenge has been the repair is done by a dealership that I didn't buy from and they have been slower then mud to get the issue resolved and have not been proactive at all which is why I had to reach out to SOA. As a case in point, when I took vehicle in yesterday to have it reflashed I asked if they would fix the fuel door, this was initially noted in my service ticket from ~month ago. They said, oh...we completely forgot about that.

Positive note is a problem is documented, you've expressed your dissatisfaction, and Subaru is wanting to work with you.

Keep us posted though.
Will do.

I have had this as well on my 2015, but only once.

Apparently there was an ecu update done by Subaru to address this issue, but it obviously hasn't worked as mine has it.
