Lately I have to open the ignition and wait 4 seconds until the D, ABS, and brake lights go out with a faint click on the dash display and then turn to start the engine. There is also a soft hum during those 4 seconds. If I don't wait, it'll start just fine but dies when I switch my foot to the brake. Then it keeps doing it even if I wait, until I let sit for about 20 minutes. If I don't forget to wait 4 seconds to turn the key, it'll start just fine for up to 186 times over a period of two months ( I've counted them). So is it software or hardware problem? Also if I don't want to wait 20 minutes till it resets whatever, I have been able to take off by stepping on the brake with my left foot while keeping my right gently on the gas while I shift to drive. Once I get going its just fine.
