Why does my car make a squeaking sound when I hit the gas?
Over time, your car’s engine belts may become worn causing them to stretch. When this happens as you press the gas pedal and the belt goes from a relatively low speed (at idle or when first starting the car, no speed at all) to a much higher speed as the engine accelerates, this can cause the belts to squeak.
Why does the a / C compressor make a squealing sound?
The A/C compressor, water pump, alternator, and power steering pump are driven by 1 serpentine belt. Since it is such a large belt, a belt tensioner helps to keep the belt tight and easy to remove and replace as well. If the belt is worn (dry, cracked,glazed) it can slip on acceleration and make a squealing sound.

What causes a high pitched intermittent squeal while…?
I can’t detect it under hard acceleration, but this may be due to engine noise. It happens during light acceleration, cruising and overrun coasting. But, it seems to stop during braking. Pads and rotors look OK. No obvious scoring or heat damage. Rear brakes had new rotors, pads and calipers about 5k ago. Fronts are older.
