Humming/clicking after unlocking - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

verywisegnome · 03-03-2015, 02:57 PM

When I walked to my car last night and unlocked it using my key fob, I noticed a mechanical humming/clicking sound coming from somewhere in/under the car. At first I wasn't sure if it was even coming from my car, but once I got in the car it sounded like it was somewhere low behind the drivers seat. The car started up fine and drove with no issues. I have not been able to recreate the noise. Has anyone else experienced this or does anyone have an idea about what may have caused it? I assumed it was something with the fuel system coming from the gas tank.

Probably something like the fuel pump priming.

This is actually in the owner's manual, complete with bad punctuation.

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.

So relax. Shit's under control.
