Arkana Hybrid Engine Power Loss

I'm having trouble with my 2022 Renault Arkana hybrid (113414 km). Engine power is noticeably reduced, and the check engine light is on. The engine runs rough and jerks during acceleration. It seems to be running lean, possibly a fuel delivery issue. I suspect a defective injector, but wanted to get some thoughts before I go further. Any ideas about the mass air flow sensor, fuel injectors, EGR valve, oxygen sensor or throttle body?

I also drive an Arkana Hybrid and had similar symptoms not too long ago. The car felt like it was struggling, and that check engine light was really annoying. In my case, it actually was a faulty fuel injector! Did you notice any changes in fuel consumption or any unusual smells?

Thanks for the response. I haven't detected any change in fuel consumption, and there are no unusual odors. Since you had a similar issue, could you tell me more about the symptoms you experienced? Also, what diagnostic steps did you take to find the cause?

Okay, the fuel consumption remaining the same is interesting. Yes, the symptoms were virtually identical to yours: loss of power, check engine light, and the occasional jerk. Given your mileage and the symptoms, I would suggest a visit to a reputable workshop for a proper diagnosis. They can check the fuel injectors, and the fuel pressure. It sounds very much like my issue. Cost me 515€ for the repair.

Thanks for the advice. Your experience has been really helpful. I'll schedule an appointment with a qualified Renault service center for a full diagnostic assessment. I will post what the solution is when I know. Thanks again.
