HELP diagnosing rattle and weird sounds - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hi everyone I just bought a 2018 gt 86 and ever since I got it, there sounds like something is loose or bouncing around. I dont think its coming from the shifter but its around that general area underneath between the driver and passenger seats. I really only hear it when I am going slow in a lower gear. I dont hear it when im driving normally and cruising. I wanted to get yalls opinion on it. Here is a video of the noise.

Most important: is the car stock? Sounds like some part of the exhaust is loose and banging around. You should still be in the warranty period, so just take it to the dealer asap.

The car is pretty much stock, I installed an axle-back exhaust but it was making the same noise before I switched it out. I assumed it was something witht the exhaust but I just havent had time to get under and take a look. Will definitely take it to the dealer soon, thank you!

Good video -

I can actually hear something.

Back in the day, I would think that you had some rocks trapped behind a hubcap. Never mind -

me.

I'm suspecting that the sound has something to do with the wheels when they are rotating. Lug nuts all tight? Maybe a brake pad dragging/lose? Maybe a lose brake caliper?

fer sure

I suggest to jack up the car and go underneath and start inspecting things like the exhaust, transmission, arm bushes etc... Wiggling things around with your hand can help you find the problem fast.
