Default Grinding noise on start up! Not sure where to post.

Hey guys I'm pretty new at this so I don't wanna sound dumb but I've been having this issue and can't seem to find a thread with anyone actually giving an answer to what the problem might be..... I have a 2003 wrx with 138k basically stock and as I turn the key to start it, the engine turns over immediately but it sometimes makes a grinding noise as if I turned the key while the car was already on. It goes for a split second then disappears. It happens intermittently so it's hard to document on video. Happened the other day, it was about 65 degrees out. Seems like it happens more often the colder it is but has happened before when it was 90 degrees out. Any thoughts? I appreciate it.

I always had this happen to my 02 wrx when the weather got cold. I always assumed it was the "actuator" in the starter getting stuck for a moment when it was cold. Never caused a problem so I never took the time to actually diagnose it but it was kind of annoying.

Good to know for sure. Shoot I hope it stays that way and not saying you're wrong but I feel like there's gotta be a definite answer to it haha

Its something with your starter most likely. Make sure the bolts that secure it are tight. The solenoid may also be going bad. While you're there check the teeth on the flywheel for wear.

Okay I'll check those. But the solenoid...how do I know it's bad? What do I look for? And idk if this is dumb to say but my flywheel should be okay. I got it resurfaced when I got the clutch replaced ~10,000 miles ago. Plus I'm not that good under the hood yet so to speak.

It's the bendix drive on the starter catching the ring gear, mine does this as well.

Starter is just old mine has 160k on it if I can remember, it'll eventually become toast. Thank God they are easy to replace and don't weight a ton

I thought i was the only one with this issue. I get the problem too always in the winter though. Grinding like the OP described after the engine turns over. As far as i know the starter has never been replaced in my car (169k) . I was scared it had something to do with the weight of oil im using in the winter and my internals.

I have also read that low battery voltage/amperage can cause this as well, if your battery is old it could be a factor.

I feel like this grinding noise has been getting worse lately, does anyone else have input or should I just go ahead and try replacing the starter?

Mine got worse and I replaced the starter. Now it starts like a brand new engine. I recommend doing this.

Mine does this as well. Just replace the starter and all will be good. I'll get around to doing mine when I find a good free unit haha. Don't always have to buy stuff.

I have a 02 and 03 wrx and both do it on cold weather start ups, I've been told it's the release bearing, does goes away if you put load on it.
Don't need to worry about it
