Electronic Power Steering Noise

Just bought 2012 Jeep Grand Cherokee Lorado.Has a low pitch sort of like a whistle after about 15 minutes into driving.
When at a stop you can turn steering wheel thus eliminating noise.

does anyone know how to get a copy of star case number S1119000004.

Hello and welcome to JustAnswer.
My name is Vlad.

If noise you are talking about comes from the engine bay area or middle to RH front corner
of the vehicle, then your dealer is correct. It is just a normal electric power steering pump operation.

If noise you are talking about comes from the bottom of the steering column, then your dealer should inspect and very likely replace the upper steering column intermediate shaft bearing assembly under warranty. Just ask them to check star case number

You can easily check if this noise is coming from the electric power steering pump which is in front of the car or from the intermediate steering shaft which is mounted to the firewall so you can hear it only sitting inside the vehicle,
Please let me know if you need more assistance.
