There is a problem with these model cars making a whining sound coming from the engine. The problem is usually the decoupler pulley on the alternator. This pulley is designed to disengage the pulley from the alternator during deceleration. I would recommend having a technician come out and replace the alternator. Due to the time it will takes to remove the coupler, you're better off just replacing the whole alternator rather than just the coupler. While this is the common repair for this model, you could also have this noise inspected first to get an accurate diagnosis of the sound in person.
