Hazard button illuminated well after the car should be asleep indicates the car isn't sleeping and it will drain the battery much faster than normal in that state. My hazard button stayed on for 7 days when I had the blank screen issue. In that state, it drained the battery much faster than normal when parked and locked. The I-Pace has no shortage of software gremlins. It's a shame because its such a great car otherwise. I'm still hopeful JLR will manage to remove their heads from their rumps at some point and straighten these things out but they are certainly trying our collective patience.
