I own a Toyota Camry that has about 180,000 miles. Yesterday, when I started the car, a high pitched whine occurred when the engine turned and the volume of the whine decreased after about 5 minutes (car was in park). The pitch of the whine increases when I accelerate, up to about 50 mph, and then the whine stops around the 50 mph mark. When the car decelerates, the pitch of the whine decreases. This does not seem to be linked in any way to the steering. The whine does occur when the car idles.
There are no alert lights on in the dashboard, only an odd noise.
What do you think?
