Motor sound in rear wheel well
Twice in the past couple of months I've gone out to my garage and heard what sounds like a small electric motor running (car is off). Both times I traced it to the driver's side rear wheel well. I start the car and it goes away for good. Only have heard it twice in a year of ownership on this 2014 GS350 FSport. Any ideas what "motor" is running while the car is off?

Look up the fuel tank evaporator check in your owners manual. Hint: it’s perfectly normal.

Normal, fuel evaporator system venting. It will routinely does this, no worries.
Even with the car off, some systems are in a operational state, that's one reason if you let the car sit for long periods of time, parasitic battery drain occurs because of these systems.
