Sounds like a faulty sensor in one of them.  

 

You can have a shop scan it for codes as the sensors will trigger fault codes in the vehicle.  C0750 (left front), C0755 (right front), C0760 (right rear), or C0765 (left rear) may be set.  A cheap code reader might not pull these so you'll have to have a shop scan it or a GM dealer can get you a SAVI printout or you can buy something like a BlueDriver or OBDLinkMX.
