Lexus LC Hybrid EGR Valve Issue

My 2020 Lexus LC hybrid is giving me grief. The check engine light is on, and I've noticed reduced engine power, smoke when accelerating, rough engine running, and even higher fuel consumption. It's also jerking and hissing when I put my foot down. It has done 75220 km. Any ideas? Could it be something to do with vehicle emissions?

Sounds like you might have a defective EGR valve. I had similar issues with my old Volvo V70 – the check engine light, rough idle, and even the smoke. It's like the car is choking on its own fumes! Does it seem worse when the engine is cold?

An EGR valve, huh? I suspected it might be something like that. And yes, it's definitely worse when the engine is cold. What exactly was the problem with your Volvo, and how did you figure it out?

With my Volvo, the EGR valve was completely jammed shut with carbon buildup, preventing proper recirculation. Think of it like a clogged artery for your engine. I initially suspected it because of the symptoms and a bit of research. I'd suggest getting yours checked out by a professional, especially since it's a hybrid system – they'll be able to pinpoint the issue for sure.

Thanks! I took your advice and went to a workshop. Turns out the EGR valve was indeed defective and needed replacing. Cost me 355€, but it's running smoothly now. I really appreciate your help!
