ECO start stop system

ECO automatic start stop system is not working does not matter day or night, cool or warm weather. Yellow light is on all the time. Started turning on-off for a while and now It never turns green. Any idea how to fix this? The car is in perfect conditions but this. Thank you

If there are no other symptoms and no check engine light on, I would say get the codes read with star diagnostics. The dealer should do it for free if the car is under warranty. Let us know what codes come up.
