I’m dealing with a weird issue on my 2018 Hyundai Accent that my mechanic hasn’t been able to figure out. When I start the engine, there’s this loud metallic scraping noise that lasts for about 3-5 seconds. It starts right when I turn the key and goes away once the engine is running. After that, everything runs smoothly with no strange noises.
Guys checked everything they could think of, but they still don’t know what’s causing it. The noise is pretty loud and metal-like, so I’m thinking it might be something with one of the moving parts.
Has anyone run into this before or have any ideas on what might be going on? I’d really appreciate any tips or advice!

 

Sure sounds like something internal in the engine aint getting lubed up quick enough at start up. as in oil starvation issue keep an eye on it.

 

Thanks for the suggestion! I actually found the solution to the issue. It turned out that the noise was due to a loose heat shield that was vibrating during startup. I tightened it up, and the noise is now gone. Thanks again for your help!
