Quick background: I bought my '13 WRX sedan brand new in October '12 and have driven 3,100 miles on it since then. I followed many owners' recommended break-in period for the 1st 1K miles and have babied my car since the day I bought it. Yesterday my drive to work was uneventful. My drive home was not. It started with a knocking/rattling noise at around 3K RPM's in 3rd gear and then became more consistent across all RPM's and through all gears within minutes. I pulled over, called my dealer and explained what was happening. They recommended I drive the car in (about 12 miles from where I was) and they'd give me a loaner for a day while the inspected the problem. During my 12 mile drive the knocking/rattling got louder. When I dropped the car off I noticed that the back bumper and underside of my spoiler were VERY dirty, like soot. Since I had just washed my car I thought this was weird but didn't really think anything beyond that.
This morning I called to see what they found and was told they were still looking at my car but they promised to get back to me by 3pm. At exactly 3pm they called back and a service team member told me that their tech's were still trying to figure out what happened, but in the meantime they called SOA and have a rep coming to look at my car at some point over the next few days. Here's where things start getting sketchy. I asked what they found in my car to cause them to call SOA and was told that he wasn't sure. When I pressed saying that for them to call SOA there had to be SOMETHING they found and that's when he told me that the dealer's service tech has suggested a complete engine replacement. Apparently, there was little/no oil in my car and a potential problem with a rod. After I caught my breath I asked if they had ever seen something like this before and was told no. I got the sense that he was deliberately being very careful about what he said, which was pretty irritating. He promised to call me once SOA has inspected my car and they determine the course of action moving forward.
Subaru recommends the 1st oil service to take place at 7,500 miles, and I'm not even half-way there yet. I've done nothing but baby my car since I bought it and everything is bone stock, everything. To have little/no oil in my engine would mean either (a) Subaru didn't sell it to with enough oil, (b) the oil burned off or (c) the oil was leaking. (b) would explain the black soot on the back of my car. The knocking noise, from searching on forums like this one, leads me to believe that there was a rod and/or rod bearing issue (I'm no gearhead, so bare with me).
Here's my big problem with all of this. Let's say I get the engine replacement and 2-years from now I'm looking to sell my car. If you were in the market for a lightly used, stock WRX would you buy mine that clearly states on the Carfax that the entire engine was replaced at 3K miles if there were other options that didn't have the same issue? To me, the resale value of my car just TANKED. I'm inclined to call SOA and ask what they are prepared to do, if in fact there guy agrees with the dealer recommendation of replacing my engine.
Anyone have similar issues or any thoughts on this? I'm also thinking about asking to be there when the SOA guy shows up to hear, from the horses mouth, what's going on and what they intend to do about it.
Thanks for reading my rant.
