I had the same problem after 5 months of purchasing a 2011 Edge. The Oil Engine Pressure light comes on and stays on after driving 10 minutes and stopping for gas- it turns off shortly after I start driving again. I had a 2007 Edge as well and never had this problem. I just took the 2011 Edge back to the dealer. They could not duplicate the problem and instead reset all computer settings. The next day the same Oil Engine Pressure light came back on. Anyone out there with any suggestions?
