I've had the car for roughly 5 days now and have just over 500miles on it. I believe the only times I've heard it was when the miles were say 300 or less.

That's a good one. I miss living on Signal just because I could go up the W every day. Tons of curves with a nice long straight and I have never seen a cop on it. Gets a ton less traffic than going up Lookout too.

Actually I'll get my chance to go up it this weekend... Going to visit family that lives up at the top of the W road so I'll get to tell you how it felt in the BRZ! :burnrubber:

So did OP figure what it was yet?

It happend to me around 300-400 miles on the car. I have 700 now. Since then all is good. The onlyt thing I can think of is the suspension "settling" in.

Had something similar in another car, could be the swaybar moving and something like endlinks or bushing bracket needed to be tightened.

:popcorn:

It's the suspension settling. With a multi-link, the rear strut and spring are separate and there is some jostling during transit. I've had it happen under quick compression situations only, but I think I can count the number of times on one hand. Another potential explanation could be the springs compressing and the metal hitting. I haven't been under the car to see if there any spring isolators on there.

Yes, mine is like that too. I'm surprised at how stiff it is.

Pulling out of the dealers lot in my FR-S I heard it when I ran over a small pothole. I was doing like 10 MPH. Haven't heard it since then. I've only put like 60 miles on it though.

Yeah i heard the cowbell sounding bang too during my test drive. Got me a little worried, but I knew I didn't run over any bottle or anything, so I assumed it was just metal on metal reaction to being used for the first/second time.

I have a theory... And we're all going to laugh if this is correct... I heard a similar noise with my wife yesterday afternoon while we were leaving our neighborhood. It appears that the passengerseat isn't always fully locking/locked after I get/put my daughter in her backseat booster. My wife said it was her seat that appeared to have clicked into place.

If this is true then in most cases I'd believe it is the same thing happening to others on here. Have you or had you accessed your backseat recently before hearing the clang? It makes sense that this could be it as the seats are mounted so close to the floor that it would cause the sensation we're getting...

That sounds like the most logical thing in this thread.

Yeah, it is weird because you hear it "lock" when you put the seat forward; however, I guess it doesn't fully engage. The momentum of driving appears to finally force the spring down causing the loud noise. What is odd is that the seat didn't lock immediately after we'd been in the car but a few miles into our drive. The pops I've heard in the past were when I was turning left or beginning to turn left so I wonder if the locks are barely out of alignment until that momentum forces it???

Anyway, I'm hoping this is all it was!
