Do dealerships replace “cricket” fuel pumps under warranty?
 

I’m in western Canada about to pull the trigger on a brz or 86. Has anybody in Canada had any luck getting either Subaru or Toyota to replace the stock pump under warranty?

Depends on the model year and mileage/age of the car.


There is no guarantee that switching pumps will make the crickets go away. It's usually due to interactions with the fuel, mainly ethanol content and additives and how they impact fuel lubricity.

Buy Shell, you won't have no more crickets.

I run shell and have crickets :iono:

Gotcha, so after market stereo is the way to go. Just adjust the volume until you can’t hear any crickets or anything else aside from sweet tunes!

Yep, if the TSB shows that your is car affected by the fuel pump chirp and your car is still under factory warranty they will replace it. I had mine replaced years ago without a problem.

....or drive? crickets are only vocal when you're idle.

And a decent exhaust to cover them up.

Like the guys said the fuel pump replacement is a Service Bulletin not a recall so the car has to still be in warranty for it to be no charge.

I thought crickets were a result of crappy gas and the direct injection pump? My car was doing it and switching to Chevron premium helped. It is still a bit noisy in the morning, but I just accepted it as a fact of owning the car; I didn't know they would replace it.

Crickets are a function of this high pressure direct injection pump period. Who knows what the exact cause is. Could be the check valve making the noise, be cavitation, could be the clearances allowing some blowby, there could actually BE a cricket in there. They all seem to do it, it is not detrimental to the function of the car.

It's just a sound, there's nothing harmful happening. I've been filling up with Petro 94 since day 1, and it chirped but it either stopped or I'm used to it, 75000 km later I don't even think about it.

Fuel quality is a factor in hearing the crickets or not. For me, they show up in the winter, and go away in the summer. I always use 93 octane. So I wouldn’t say it’s only because of poor quality fuel, but a combination of that and temperature. For me anyway.
Oh one other thing I noticed. When I bought my car, I heard the crickets at idle. I’m guessing they threw in the least expensive 89 octane fuel. After getting a full tank of 93 in there, the crickets disappeared.

That is the total opposite of what I had. I had them in the heat of summer no matter what fuel I ran. When it got cold they went away.
This is why it is so hard to narrow down cause and affect. No two people seem to have the same results no matter what fuel, temperature, additives, driving style, etc. etc they tried. The good news (for me) is that I have never had a peep out of the 2020!

Oh and 89 octane fuel is no poorer quality than 93 no matter what marketing you wish to believe. It is just a difference in in knock resistance not a measure of quality

I was just thinking that also, I’ve had the crickets at random times even when it’s warm out. So there isn’t much rhyme or reason to it. Typically with winter fuel I get the crickets more, but it’s random.
That’s really good news the 2020 doesn’t have it. They must be using a different high pressure fuel pump, or different internals.
