Tried searching but not sure I've read anything about my issue. I bought my 2024 4Runner new and it's almost a year old. I parked in the garage and was standing beside the 4Runner about 5 minutes later when the truck started sounding like someone was releasing air from a balloon that had been blown up really tight. It was a high pitched sound that went up and down somewhat for a few seconds. I'm thinking it was from the engine bay but not 100% sure. I've owned multiple 4Runners and never heard this before. It's not the evap sound you hear several hours later. This was 5 to 8 minutes after cutting the truck off. I cranked it back up then cut it off to see if I could duplicate it but no luck. And suggestions?

I believe I've had my 2023 do the same thing on a few occasions. I figured it was some electrical or other system that just does its stuff on occasion.

Do you have an vehicle alarm system that could be malfunctioning? Were you in same spot when it activated?
Purchase a trail cam -like hunters use- and set it to watch your truck 24/7 and see if there is a pattern.

This will be of absolutely no help whatever, but I had a 1st Gen Taco that would intermittently, randomly make a sound like a heavy coil spring unwinding. Sometimes when running, sometimes when off. Did it the whole time I owned it. Never did figure it out. One of the mysteries of life.
Apparently you didn't read my original post. Nobody is coddling anything. I simply got out of my vehicle and was still in the garage when I heard a strange noise coming from my vehicle. But thanks for your helpful post.
Now and again my evap system near the fuel tank will make noise only 5-10 minutes after shutting down. The noise only last a few seconds.
Yes, I have read the manual regarding the 5 hour evap purge and have even heard it at around 5 hrs.
However, this noise comes from the same area and is definitely not 5 hrs after shutting down. It takes me 5-10 minutes to change my clothes and shoes and get everything ready to go mountain biking.

Maybe that's what it is. I've also heard the ABS pump can also make noises after cutting the car off and that it's normal.
I appreciate the responses!
