Just traded in my 2015 Forester with 219,000 miles and the original spark plugs.

I had similar problems with mine until I tried stock F80 M3 plugs. Mfg #12120039634KT1. Mine was 07 N54 FBO.

BMW
Part number: 12120039634KT1
Guy was gunna charge me $720 USD for changing my serp belt and another $550 USD for changing just my spark plugs. That's $20 for the serpantine/drive belt, $150 for the belt tensioner and I think another like $120ish for spark plugs (B58 engine). So in total I saved myself roughly $1,000 just doing it myself.
Pros: saved roughly $1,000
Vehicle:
BMW
Normally that's a result of a failed spark plug seal. If you have no other problems I would put new spark plugs in it and check them at the next oil change.
Vehicle:
Subaru Impreza
Since then I have take good care of it, replaced the brakes on schedule in August 2020 and then in August 2021 new spark plugs.
Pros: replaced brakes, new spark plugs
Vehicle:
Subaru Forester
My 2002 had a similar issue. In my case it was the spark plugs, $250 fix.
Pros: easy fix
Vehicle:
Subaru Outback
I did track it extensively, probably 3-4,000 km of track use. The only thing it needs is brake fluid and better pads and you're good to go. My car was flawless for the entire time I had it. It threw a CEL right before I sold it that was solved with a simple spark plug change. It never overheated at the track and it was a lot of fun there and very refined and comfortable for highway travel.
Pros: flawless, refined, comfortable
Vehicle:
BMW
We just got the 60k service done (spark plugs) and it still does it.
Cons: shaking still present
Vehicle:
