Why would a car be making a high-pitched whining sound?
We just noticed that my husband's car (Subaru Impreza, 2004, 100K miles) is making a high-pitched whining/ringing noise. The thing is, it makes the noise when the engine is off. (It's been turned off for 2 hours now.) It sounds like it's coming from the engine. Also, when he uses the remote to unlock and lock the car, it kind of distorts the whining for a second (but it continues). Google is no help -- I keep finding results about cars making noises when they're actually being driven, but his car is just sitting there, doing nothing. Could it be the battery or something?
