Lexus NX reduced engine power

Hi, I have a 2020 Lexus NX with a gasoline engine. The engine power is noticeably reduced, and an error is stored in the error memory. Could the computer module be the cause? The car has 203533 km.

Hey there! I had a similar issue with my Lexus NX (don't know the year anymore). Reduced power and error codes... sound familiar? Did you check the main relay?

Main relay? Where is that located, and how would a defective relay manifest itself?

Yeah, it's a common culprit. Controls the ECU power supply. If it's faulty, the ECU might not get enough juice, causing errors and reduced performance. Look in the fuse box under the hood. Honestly, with ECU problems, you might be better off visiting a workshop. They can properly diagnose it.

Alright, thanks for the input! It turned out to be the main relay, as suspected. Cost me 120€ to have it replaced.
