You sure they used the right oil?

they should of, but how would i check what type of oil they used?

You might check your work order or call whoever changed the oil.

No oil (except maybe 3in1 oil) would cause an engine to knock under light use.....;)

Is it the fuel injectors leaking air, then causing knock?

There is concern about the reliability of the seals and the design/quality of the system.

well i checked the oil level, called in about the type of oil they used and they claim that they used the right type

Well, I reckon it's time to post a movie .... ;)

I've noticed my engine doesn't sound quite right when cold either. I was going to chalk it up to a Subaru quirk but the more I think about it the more I'm worried. Would love to hear a video, I'll try to get one of my own if I can replicate.

Ive tried taking a video of the noise, but my phone wont capture the sound :bs:

tried taking a video but i cant capture the sound :sigh:
if you could take a video and post it, it would really help just to see if we both have the same problem

Not sure if I can get it either, it isn't consistent and it doesn't sound like the engine is falling apart, it just sounds kind of truck like and unrefined. Honestly wasn't going to post anything about it, chalk it up to normal noises cheap sports cars make.

I'm 95% sure that a dealership won't do anything without a CEL or ECU code. So that leaves us paranoid guys in a tight spot.
:bonk:

LOL ya your right, I'm heading to the dealership tomorrow to replace my tail lights because water is leaking inside. so I'm going to inform them about it. Hopefully the knocking starts when they see it

Is it like a rhythmic "marching" or "chugging" kind of sound?

its more of marching sound

I hear it too, ever since the car was new. I figured it was something to do with the fluids not being warmed to optimal temps yet. Will try to get a video of it when I cold start my car after work for reference
