Holy ESS AITCH AI! And Gooood Morning, AMERICA!
Come four in the morning, the dog barfs all over the bed. I strip the blankets and drag them to the garage to throw them in the washer. As I’m stuffing bedding into the Samsung, I hear this weird BUZZING noise.
I figure it’s the neighbor’s air-conditioner about to break down. But it seems kind of loud for an AC unit way across the road. If it’s coming from the car, I can’t tell where it’s coming from. Search around…can’t pinpoint the source. Finally I think it may be in my attic.
Go inside, get the keys, open the garage door, pull the car out into the driveway so as to heave the attic ladder down from the ceiling. Hop out of the car, re-enter the garage, and…no noise.
Back to the car: examine. No noise.
I conclude the sound was coming from the car and that turning the engine on must have turned the noise off. Turning the ignition key works all sorts of strange magic with these new computer-operated clunks. I’m annoyed but glad at least I don’t have to call the fire department for some electrical issue having to do with the house’s aluminum wiring. Whatever it is, though, sounds like a potentially expensive fix.
Return the car to its nesting place. Turn on the washer.
All hope of sleep is now gone. So what does any self-respecting Netizen do but search Google: “buzzing sound coming from toyota.”
And forgodsake, check this out:
EDIT: found the answer to this one on page 8 of the manual (doh!) “Approximately five hours after the engine is turned off, you may hear sound coming from under the vehicle for several minutes. This is the sound of a fuel evaporation leakage check and, it does not indicate a malfunction”
Just experienced a weird one.
I went out to my detached garage where my 2015 Highlander XLE is parked, and I heard a buzzing / vibrating noise. After some investigation, I isolated the noise as coming from the Highlander itself, even though it had been sitting parked and turned off for roughly 5.5 hours.
The noise was loudest underneath the vehicle and it stopped when I popped the hood (although there may not be a direct cause/effect between the noise stopping and the hood opening). Fortunately, I took a video of the event to share with Toyota.
Any thoughts? Has anyone else experienced something like this before, either with this model or any other?

Really? REALLY, Toyota, is this absolutely necessary?
Apparently this helpful feature has existed at least since 2013. If you weren’t already crazy, this sure as hell will make you that way. Five hours after you turn off the engine, eh? So this has been going on since 2:30 this morning? When is the racket supposed to stop? Not until you turn the damn thing on again?
Argh. I should’ve bought a mule and a cart.
Wow, now that is a new one. Well, hopefully it isn’t loud enough to wake you up.
Well, my bedroom is in the back of the house, so even though I’d alreqady been awake with insomnia for a couple of hours, I didn’t hear it until I walked out to the garage. However, if you had a house with a bedroom over the garage, it could very well keep you awake. For awhile I thought it was coming from the attic — that’s why I moved the car out, so I could climb up in there to track the noise down.
