My MY 2012 Has always been very trouble free. However, I've started seeing a strange behavior with it over the last 2 months where the charge door has been spontaneously opening while going down the road. Today it happened again while traveling home on the interstate at 65 MPH. It seems to happen when a bump is encountered in a certain way as it does not happen all the time. Today it was a bridge expansion joint. Last week it was a bump in the road while traversing a "round-a-bout". This is about the 4th or 5th incident. Any one have any ideas? I've had this car since new and it has never done this over its 42000 miles except since the last couple of months.
