My start button behaves a bit weird. For about 30 seconds after unlocking the doors, I can start the car as normal, but after that, I first have to cycle through the ACC and ON modes before the car turns on (to READY mode). I am pressing the brake pedal throughout the process, doesn't matter how hard I push it, still have to cycle through the modes. I have tried using the 2nd key and reconnecting the 12v battery.
Has anyone experienced this before? Is there a DIY solution or would this be a matter for the dealership?
