Lexus LS reduced engine power

I'm having a bit of a headache with my 2016 Lexus LS hybrid. Recently, I've noticed reduced engine power, and after running a car diagnostic, an error code popped up. Has anyone experienced something similar? I'm a bit of a novice when it comes to car stuff, so any ideas on what could be causing this?

Interesting. I have an LS too, and something like that happened to me a while back. Was the car ever chipped or tuned by a third-party provider at any point?

Tuned? Actually, yeah, the previous owner mentioned something about chip tuning... Why do you ask?

Well, in my case, the error stored in the memory, along with the reduced engine power, pointed towards a faulty chip tuning job. Apparently, it can mess with the engine management system. I'd highly recommend getting it checked out by a trusted workshop; they should be able to diagnose the issue and potentially re-flash the ECU to the original settings. That might be the source of your woes.

Thanks so much for the insight! I took it to the workshop, and you were spot on. Turns out the chip tuning was indeed the culprit. They reflashed the ECU, and it's running smoothly now. Cost me 180€, but definitely worth it. Appreciate the help!
