"Scraping/Scratching" noise on acceleration?
Hello all,
I recently purchased my '17 BRZ w/PP back in February. It has been a fantastic car so far and haven't had any issues. I'm at about the 3200 mile mark. Recently though, I am hearing a scraping/scratching noise whenever I accelerate. The sound only lasts for the brief moment that I put my foot on the gas. It does not happen on every single acceleration. It seems to be random as I couldn't replicate a pattern. It's not super loud (not loud enough to get on video very well probably), but it is definitely audible if you're in the cabin. It does not sound like it's coming from the rear, but somewhere in the front. I can't tell whether it's something in the engine area, the suspension, or the brakes? I have really been noticing it within the last month or so, but now I'm not sure if it has been happening for awhile and it is now just really getting my attention. As I don't have much experience with this vehicle, is this a normal sound I don't need to worry about? I was planning on taking it into my dealership anyway since it's under warranty, but I'd love to hear thoughts first. Thanks! |

Well, I don't think that sound is "normal" ..... at least either mine doesn't do it or I can't hear it ......
Maybe if the dealer gets it up on a lift, they can spot something that is lose .... humfrz |

If it's at a specific RPM/RPM range it most likely is a rattling heat shield.

Is it possibly the sound generator tube?
I plugged mine right away because it gave a raspy sound in the cabin on initial acceleration, which I suppose could sound similar to a scraping noise. |

I had a bad heat-shield on my front-pipe. Noticed it right after the break-in period. Took me a long time to figure out what the hell it was, but it was fixed under warranty. It sounded more like a grinding/ metallic scrapping noise and only heard it under acceleration. I would start by check all your heat-shields and go from there.

Is heat shield rattling a concern that should be fixed? At 3.5-4.5k rpm I get a buzzing that sounds like it's coming from the dash area. I've tried to ignore it but I hear it every time =\

I have this issue as well. Brand new 2017 Toyota 86 not even at 1500 miles yet and I recently noticed when I step on gas pedal a little harder than usual or sudden throttle acceleration I hear a a short brief metallic scrape screech click grind what ever you call it. So what could this be guys? I broke in my car the 1000 miles properly never even revved over 3500 rpm. Never scraped or bottomed out the car either. Put the car on a lift the other week just to inspect the underbody and everything is flawless no sign of any defect or anything. Car is a manual so maybe the sound generator rubs in the aluminum intake manifold when you step on gas cause you know how the engine moves when you give it some gas but it doesn't do that screech sound when in neutral and parked. I'm curious to see where this short little scrape sounds is coming from

About 2 months into the ownership of my BRZee I started to note a funny high pitch screeching/swirly sound. It kinda sounded like something metallic spinning (much like an angle grinder but really faint) but it would only happen intermittently.
As my ear become more attuned to the noise and after reading various posts about unusual noises, it boiled down to our friends the "crickets". Taking the car into dealer first week of July for a service and check on the "crickets". |
