About 14000 miles on my 2012 wagon. Its been in my garage every night for a 1.5 years and I've never noticed a noise coming from the car. Parked for over 3 hours. I stepped into garage and heard what might be described as humming, imagine a compressor running in your neighbors garage, very faint. I searched all over the garage and water heater area. Even after going outside and being stumped for a minute i went back to the garage and tracked the sound to the tailpipe of the car and finally the trunk. Just above the left rear wheel well. Under the mat in a metal cage 10 o'clock from the spare. The sound stopped 5-7 seconds later.
The key was not in it. The hood was cool to the touch. I don't live in my garage but I've spent some hours and never heard the car do this? ?
Fuel Pump? What are the electrical components?
Has anyone ever experienced this?
Thanks in advance. Looking forward to exploring this site
