Seeking advice: Knocking combustion in 2018 Renault Fluence - increased fuel consumption and power loss

Jerking on acceleration

Weird engine noise

Loss of engine power

Poor fuel economy

Check engine light on

Hi guys, I've been having problems with my petrol engine for some time now, a 2018 Renault Fluence that already has 65227 km on the clock. The indicator light is on, the engine loses power, jerks when accelerating, consumes much more fuel than usual and makes strange noises. I was told that it could be due to knocking combustion in at least one cylinder. Has anyone ever had similar problems and can tell me about their experiences, especially regarding the repair at the mechanic? Unfortunately, I didn't have a very good experience on my last visit to the garage. In a nutshell: I'm really at a loss and don't know what to do. Thank you for your advice! Best regards!
