Hello. New here and thanks for all the valuable information that you have.
2017 Fallback. Keyless start. When cold unlocking/ starting etc is fine. After 15 mins the 'not recognising key' warning comes up, the alarm sounds, the start/stop flashes red and the radio etc goes off. However, unlocking/locking and start stop works. I have: replaced batteries in fobs. Disconnected main battery, cleaned terminals. Tried a reset by locking/unlocking with key 8 times. I removed start/stop button and cleaned terminals etc. In the morning when cold all works fine for 15 mins then warning light and alarm. Any more ideas? Or is it dealer for scan and component replacement? Thanks for reading. Simon
 
Sounds more like a problem caused by discharged/dead battery or faulty ground connections or faulty charging.
Thanks Mike. I checked groudind and when running voltage at battery is 14.4. Not sure what to check next..... could be an expensive phone call. Thx for the feedback
