XC60 charge, Hybrid mode – Burner

Hello together, have a charge mod.2024. Runs since 11.23 (today 11.000km) For about 3 months the combustion engine is often switched on in hybrid mode. Driving white very defensive. This only happens when I stop, bring the car to a standstill. Not always but more often. Then the petrol engine runs for kanpp 1km, then it goes again with electricity. (accumulator always sufficient). Does anyone know this problem? Thanks and greetings
