Check your transmission fluid level, as recommended in the Owner's Manual. Also, if your car is equipped with power steering, check the fluid level in the power steering reserve.
If all fluids are at recommended levels, see if you can locate the noise. If it is in the engine compartment, try to determine if the noise is coming from any of the serpentine belt pulleys.
Sometimes the bearings on air injector pumps fail in higher-mileage vehicles, first causing a "whining" noise, and ultimately resulting in the serpentine belt "chirping" or squealing on acceleration. Best you can do is make sure all fluids are at recommended levels, then try to pinpoint the source of the whining noise for further diagnosis.
Hope that's helpful!.
