Default Weirdest noise coming from under the trunk

Hello

Today it was the weirdest thing.

I got home at 12pm, I parked my RCF in the garage. At 10pm I walk into the garage to grab something and I heard a noise, weird noise, what is that? I thought. Sounded like a one of those small air pumps to pump up the tires.
Suddenly I noticed that the noise it was coming from under the RCF trunk. And after 15 seconds stopped.

The care were parked for 10hrs, anyone knows what it was?

I heard some people reporting fuel pump problems but while the engine is running.

Its fuel pump checking the pressurization of the system. Entirely normal. My wife's IS and my NX (when I had it) did the same thing. You'd walk into the garage at like 11pm and hear something running and then it would click off.

At times, on the my RC-F, this noise lasts well over 5 minutes! My IS-F only did it in short bursts.

Page 8 of the Owner's Manual:

"Noise from under vehicle after turning off the engine: 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."

Two different noises. The one posted by the OP is normal.

?

Lexus will be announcing a fix for those who have noisy pumps.

I am not referring to the correct functioning of the pump, which will at times make a sound as it releases pressure in the system.

Great info I remember when I first heard that noise, it freaked me out b/c I was right next to the car and it was off...not expecting it...haha.
