2017 Forester 2.5i
Greetings, I have a 2017 Forester with the FB25 engine and the manual transmission. The engine has consumed oil since it was new, about a quart every 2,500 miles. As such, I was all over the maintenance of this motor. This meant frequent top offs of the oil level and 5k oil changes with the more expensive Mobil 1 EP 0w-20 and OEM filters. My driving is 90% highway, 75MPH, 40+ miles each way, six days a week. This means that I have amassed 80,000 miles since it rolled off the lot in 12/2016. A few months ago I started noticing a faint clattering sound when the engine was under load and an occasional rough cold start. I cleaned the MAF sensor and changed the air filter with little improvement. Last Tuesday morning I got about a mile from my house when I lost power and the engine began to knock. I had it flat bedded to the dealer who is now telling me that i need a new short block. They are currently processing the claim through the Subaru extended warranty that was purchased (thank God!). We are waiting for the smoke from the Vatican chimney on the claim. I am at a bit of a loss about this situation, I really thought I was doing all of the right things, good oil, frequent changes, OEM filters, mostly highway miles. I drive a lot, but I have never failed to get at least 250,000 miles out of any engine that I have owned. I know how to maintain a car. This has been a major disappointment! Hopefully I will be covered and will get past this. I am now questioning keeping this vehicle long term. I would welcome constructive input or advice on what needs to be done to get this car back up and running, and/or long term viability of this drivetrain. TIA!
