Power steering warning light on
Then you should get it serviced RIGHT away!
The PS motor was replaced on my 2010 Cobalt under recall. There is a possibility that your Aura falls under the recall. Here is a link to the NHTSA site that lists the recall.

A dealer can look up the VIN number to check if the recall applies.
