First, let me start this off by saying I love what the BRZ is. However, a week and a half a go, had the CEl and slip light come on, code P0017. Had rough idle after a while. went home checked code and cleared it. Called dealer and went in, my mistake by clearing code. Dealer said they could do anything since there was no code. So, didn't even want to drive it, but a few days later drove it again and CEL and Slip light on again. This time I didn't check code, thought it would be the same. Called dealer to have them look at it. Since I am anal about cars, changed oil at 1000 miles to make sure any initial metal wear is out of the oil, all this happened at 1250 + miles. The dealer claims they talked with Subaru tech line and stated that since I used I Fram Tough Guard filter, that was the first thing to eliminate. So, $75 dollars later for an oil change...like that is the problem. I told the service guy, you have left me with no choice. He stated that Subaru's are very sensitive to after market items (oil filters included!!!). After I got home, I wrote to Subaru of America expressing my displeasure with the service to date and the fact this is my first Subaru and I am very disappointed. since I have bought cars, from 1984 , only owned Toyota's, Honda's and one Mazda, never had something like this. I only did PM on them. Waiting to see what happens. Planning on driving a while to see if it happens again tomorrow.
