Fix the auto stop start first.

Get the stop start battery load tested, if its still the original its definitely getting towards the end of its life. Check for codes as well.

They lose capacity over time and once the car detects they aren't at a suitable level, they disable the system. This also stops the hybrid system from working.

 

Thanks for your help, 2013GV. When you say the “stop start battery”, do you mean the main battery under the bonnet?

 

Yep, the " normal " battery

 

Tengo un Swift 2022 Hybrid, tiene 40.000 KM . Lo híbrido ya no funciona. Muestra que la batería se carga y está completamente llena, pero el motor eléctrico no ayuda y tampoco funciona el Starstop. Se siente en verdad en el consumo del auto, dando anteriormente hasta 22km/litro y ahora da 16-18 km/lt

I have a 2022 Swift Hybrid, it has 40,000 km. The hybrid function no longer works. It shows that the battery is charging and is fully charged, but the electric motor doesn't help, and the Starstop doesn't work either. It's actually noticeable in the car's fuel consumption, which previously produced up to 22 km/l and now produces 16-18 km/l.

Has to be the start/ stop 12 v is depleted

 

What condition is the start stop battery in? Get it load tested.
If that starts to lose capacity ( its getting onfor 3 years old if its the original) then that will stop the hybrid system from activation and also prevent the start stop function as well.

Are you referring to the battery up front under the hood or the one under the seat? Either way, both batteries are original and are a little over three years old.
