While driving home after purchasing the car, the onstar system kept stating that we were off course (it didn't recognize where the car was). Onstar attempted to repair it remotely, which didn't work. Took car to a GM repair facility (dealer) who attempted a repair. After that, onstar would occasionally dial a number by itself using the built in cell phone without my initiating the call, and also would hang up by itself while I was talking to an onstar representative. The GM repair facility (dealer) said there was no problem, but onstar verified that they called the dealer and advised them that there was a problem.
