Got the crickets. Any other 17 MT's?
 

Seems to be intermittent so far. This is the first tank of E85 this year, so maybe I can attribute the crickets to that. It has always had just a hint of the noise every now and then, but it is obvious now.

Should I take it to the dealer and burn it in the lot as protest? Should I see how many pumps I can get the dealer to replace? Add a quart of engine oil to the gas?*

*The above paragraph is a joke.

Any other 17 MT's you know of with crickets? I don't remember reading about any here.

It didn't seem to make a difference in the year of the car. The 13s were chirping as much as the 17s in the poll. I'm convinced it's all in the type of fuel used. I've run nothing but Chevron 93 in mine since the pump was replaced with the last TSB and still no crickets.

Mine started chirping within 3-5K km. Doesn't bother me though

'17 AT BRZ with crickets here. I've only ever run 91 Shell or Chevron in it, first noticed the crickets when I had been on Shell for a while but I'm now starting into my 3rd tank of Chevron in a row since noticing them and the crickets are still going strong.

Here's the fix for crickets:

I noticed a little bit on shell 91. switched to petro 94/stinson 93 and no issues since.

I don't remember when my '13 got infested, but it's nice to know they still have not fixed the problem.

Chevron 92 for me as well, just switched to E85, loud crickets. Maybe they enjoy the corn 'licker and are having a party.

Nothing above 91 to be found out here.

I haven't had crickets at all since I moved to Florida, so I'm even more convinced than ever that the crickets are caused by the fuel blend (winter/summer) and the additive packages. Since it's warm here throughout the year, our blends don't get as much butane as in colder climates.

When I lived in Texas and Louisiana, I'd get crickets on winter blends and on cheap gas from Sam's Club or Marathon stations. Sam's gas was the worst. I thought the fuel pump was going to jump out of the damned car and go hopping down the street on its own.

And before anybody says it, I'm almost certain that non-ethanol gas won't fix it. I tried it when it was the big bandwagon fix, and it made my crickets worse. I'm pretty sure it was because it was just shitty gas from mom and pop stations that was either cut down with a lot of octane substitutes or had really bad additive packages.

17 86 Auto only have used non ethanol 91 with 4400 miles and no crickets still.

22R

That's interesting. I'm in Florida and have never had crickets. I only use whatever 93 octane is cheapest. Usually Sunoco or Cumberland Farms. Neither of which are "top tier" fuels. So maybe it's the additives that cause it.

~4000 miles 17 MT 86.

Either 91 no ethanol or 94 ~10%. No crickets.

Also did ~3000 miles with the redesigned pump on the FR-S and the crickets never showed.

I add 2oz of 2 cycle engine oil if I start to hear the crickets. This seems to solve the problem for at least a couple of tanks of fuel. I read to do that somewhere else on this forum a while ago, though I'm not sure which post. But I've been doing that and have no problems. I pick up this stuff from walmart:

I have heard them on and off on my 15 since new. Never bothered me, especially when the 100k Audi next to me at the light is doing the same thing.

Excuse my ignorance, but what are the crickets? I imagine it's ticking sound from my engine. 17' MT w/6400 miles.

Interesting, thanks for sharing. My S2000 did something similar but more like a ticking diesel at 70k. Valve adjustment and it disappeared until 120k.

Only shell 91 and royal purple injector cleaner, 15 months cricket free! However after long trips they almost sound like they want to come back (real faint) but the next day I start her up she purrs.

Wait, I thought the new fuel pump fixed the crickets? Don't remember the part # but I think it was released in Nov 2016. Toyota installed mine via TSB about 20k miles ago and my crickets have been gone ever since. And that's running both E85 and Shell 93. Is it possible some of the early 2017's got the old fuel pump before the change?

I doubt that actually works. Seems like it "worked" for some people and did nothing for others, which is potentially a sign the situations where it "worked" were just confirmation bias.

If you think it works anyway, be sure what you're using is ashless. That Walmart stuff you linked doesn't say anywhere that it's ashless or low ash. Running high ash oil through a fuel system can cause carbon buildup on engine valves.

It's not ticking. This engine sounds like a sewing machine, but that's not the crickets. The crickets are the high-pitched chirping you could hear in that video. With the hood closed, it often sounds exactly like crickets.

Once I stopped at a gas station in rural Louisiana for some coffee. While I was inside the store, I heard what sounded like my engine chirping and had a moment of panic thinking someone had started up my car outside. But no, it wasn't my car. There was a cage of bait crickets in the store for the fishermen.

No amount of valve adjustment will fix the chirping, because it's not valves. It's the high pressure fuel pump. This car is not the only car that has the issue. Some other cars with HPFPs also chirp.

You have a 50/50 chance of the chirps. I think there were/was three iterations of the pump. IIRC, someone here a few years ago had two or three dealer-replaced pumps and they all chirped.

Luck of the draw, no big deal.

2017 MT BRZ, 25,000kms.

No chirping. Have run 94 (ethanol free) and mostly run 91 (~10% ethanol).

Honestly, I never understood why this bothers most owners. I just consider it a quirk of the car.

It sounds like something is broken/loose. I can't stand when things squeak or rattle and have the urge to fix it as soon as possible.

Pretty sure it's not luck of the draw anymore. I've gone 20,000 miles on the latest fuel pump (SU003-07326) and the chirps have been totally silenced. I'd recommend this TSB for anyone who is still under warranty and is having this problem.

I had the latest pump installed by the dealer about a year ago. My chirps came back last month. It only chirps occasionally though and it seems quieter.

I love all the pure mechanical sounds this car makes. Crickets and sewing machine included. It just reinforces what this car is intended to be and why I chose it over other cars.

In fact, sound is one of the reasons I chose a PD supercharger over centrifugal or turbo. So much better (to my ears) than exaggerated blow off valves and overly loud and raspy exhausts that seem to dominate the aftermarket for so many cars.

Squeaks and rattles, on the other hand...... Uggg. So far my '17 is rattle free @ 20K miles.

Fair enough about sounding like something is off! You must need a louder exhaust to cover it up. I only really notice it in drivethroughs now. :cheers:

Enjoy that while it lasts :lol:

This.

My car has developed a rattle in 2nd, 4th and 6th gear.... -_-

No rattles here, just a hi-frequency buzz left front dash on the highway. ALmost sounds like its coming from the speaker.

Perhaps my specific car is of the defective sort then. It came with a rattle that sounded serious to me, and had the dealership stumped. I'm going to bring it in again, because if this is it progressing from the same issue, then that would be very depressing.

Lol, I haven't experienced that sound yet then.

So the chirping sound is generated from the fuel pump itself?

Just to rule it out... is this your first manual car?

It is.

If only you could sit in my car and see that how I drive, I think at least, isn't the issue. I'm also not a self taught manual.

It's a sound coming from the gear stick when accelerating after a certain rpm.

The other rattle I had mentioned as well came with the car, but isn't in the same location.

Mine rattles too, can't remember if it's in the same gears. But I lifted up the reverse lockout a bit while it was rattling and it stopped. So I figure maybe it just needs to be raised a bit, or maybe cushioned

Embrace the crickets! I know I have....

Idunno. I tried taking the gear stick trim off already and moving it around to see if there was anything loose, but no luck. Really hoping this isn't a big issue.

Yep. They keep issuing new revisions of the pump. It keeps chirping. Maybe the latest iteration has fixed it. I don't know.

At one point Toyota was experimenting with putting insulation all around it so you couldn't hear it. A member here on this board was one of the test cases and had the foam installed at the dealer. It actually chirped louder. Apparently the insulation was holding heat in and making the sound worse.

Other manufacturers have solved the problem with sound deadening insulation, but they designed it that way from the beginning.
