Lexus RX Overheating Issue

Power loss, yes, I've noticed that sometimes, especially uphill. Fuel efficiency has taken a hit too. How did you deal with it? Did it turn out to be the bypass valve in your case?

Yep, those were the exact symptoms I had. Turned out to be related. Best to get it checked at a workshop. I wouldn't mess around with it myself, especially with the hybrid system involved.

Thanks for the advice! I took it to the shop, and you were spot on – it was a consequential error. They fixed the root cause, and the bypass valve issue disappeared. Cost me nothing extra! Appreciate the help!

Interesting. I own an RX as well. Sounds a lot like what happened to me a while back. Was it accompanied by any engine stalling or power loss? What about fuel efficiency?
