So I’m sitting at a supercharger and after about 10mins of charging I hear a 4 second long high pitch tone and then my passenger door randomly opens up! I am shocked and confused at what just happened. I called the SC and they said they would contact me back first thing in the morning. This is the first time i’ve experienced this issue and since last week I have been getting a rather harsh ride while feeling random vibrations from around the car. At speeds anywhere above 60kms I begin to hear a pulsating sound from underneath and in front of the car. Could this be a battery issue? Has anybody else experienced these issues? I go in for my first annual service next Tuesday.
