By 2009 the car had stopped being a car and became a wheeled computer - a fully digital thinking machine, therefore it is best to research first and then proceed slowly.
It is possible the battery has a failing cell resulting in a rapidly falling battery voltage, fooling the brain into thinking a door has been opened. Alternatively, the brain might think a door has been left open if one of the switches or wiring has failed. Switches to supply information to the brain are often buried inside the door catches.
I once encountered a car with a maladjusted door that had prematurely worn the striker that then failed to enter the door catch sufficiently to operate the switch. Another switch was buried in the bonnet (hood) catch. Clearly it hadn't seen an oilcan since day one...
