OK guys, I'm really starting to think this car is possessed
. After driving the car today, I parked in my garage just like always. I was looking through my toolbox and suddenly there was this very strange noise coming from the car. It sounds like a loud hissing/whistle. It kinda sounds like someone letting the air out of a tire or maybe a balloon. It lasted maybe 7 or 8 seconds then it stopped. I thought maybe it was a tire but they were all ok. I've heard this a couple of times before after driving but never really paid attention to it until now. I guess it sounded louder inside the quiet garage. All seems well with the car, I drive it 60 miles every day with no issues. What could making this noise? If it helps it seems to happen a few minutes after shutting off the engine. What do you guys think??
