I am having a major problem with Starting and Stopping the car. The worst part is that it's intermittent. When I push the Start/Stop Button the car will not shut off and the key won't eject. Volvo first told me they needed to file down the Shift cable because it wasn't going into Park all the way. After that didn't work they said that it had to be the Sirius Radio that I had installed. We disconnected that and it is still doing the same thing. Any help would be appreciated. Also there were a few times when the engine did shut off the key ejected and the accessories stayed on and killed the battery! Thanks Ken
