I was in line for the car wash and suddenly noticed that the VSA was turned off. I pushed the VSA button to turn it ON but did not help. I turned the ignition to off and started the X again. This time VSA was fine. My X is only 4 weeks old. Should I be concerned? Or is this a common thing that happens once in a while? It is not that I needed the VSA to be functioning at that time but just the fact that it turned off with no reason.
