ET2013 Posted November 11, 2013 Share Posted November 11, 2013 About 1 hour after parking and shutting down the car in the garage, I was out there again and heard a humming sound (like an electric motor or a stuck relay), which I tracked to the rear left quarter (driver's side), just above and behind the rear wheel well. Venting the gas cap did nothing however turning the key on and off without starting the engine stopped the noise. In doing this the electric fuel pump comes on, which is a different sound than the humming I heard. This had happened once before, about 2 months ago. The dealer suggested today that I simply monitor it until it became more frequent so they would have a better chance to track it down. Anybody heard of this before? What was it? Thanks Quote Link to comment Share on other sites More sharing options...
LosDiosDeVerde86 Posted November 14, 2013 Share Posted November 14, 2013 First guess would have been fuel pump. But now I'd suggest that you simply monitor it until it becomes more frequent so the dealership can have a better chance to track it down.

rhackett0221 Posted November 20, 2013 Share Posted November 20, 2013 I have the same issue as ET 2013. Same circumstances -- car parked in garage for at least an hour. Same location for source - underside of rear driver's side. Have detected noise when letting the dog out at night several times. Noise shuts off after 10-15 minutes. Have not sat in cold garage (here in Maine) for an extended period to see if it come back on again. Any ideas? Quote Link to comment Share on other sites More sharing options...
Scottaru Posted November 20, 2013 Share Posted November 20, 2013 Fuel pump was the first thing that came into my mind as well. Quote Link to comment Share on other sites More sharing options...

rencast Posted January 4, 2015 Share Posted January 4, 2015 We bought a 2014 Outback in August, and on two occasions have heard the same humming noise coming from the driver side rear wheel well when car is off. The car is garagedd. Might be happening more, but heard it these two times. Wondering if there's been a solution to this. Quote Link to comment Share on other sites More sharing options...
brus brother Posted January 5, 2015 Share Posted January 5, 2015 I suggest that you print out this thread and bring it to a service manager and ask that they get an answer from SOA. They are generally responsive. Ask to make an appointment with district manager if they baulk. Show them that yours is not an isolated issue. There may be a simple explanation... and if so, you deserve one. If not, ask them to fix it. Quote Link to comment Share on other sites More sharing options...
