Escape Hybrid Overheating

That sounds familiar! I had a similar issue with my old Renault Megane, which also resulted in engine overheating and the check engine light coming on. In my case, it turned out to be a defective speed sensor causing the fan to not kick in when it should have. Have you noticed any unusual fan noise or the absence of it?

Interesting. So the speed sensor was preventing the fan from working even when the engine temperature was high? Was it an easy fix?

Yes, that's correct. The sensor acts like a traffic controller for the fan: if it goes bad, it throws everything off. As for easy... it wasn't something I could handle myself. The sensor on my Megane was tricky to reach. It needed a replacement and then the mechanic cleared the error code. I'd advise getting it checked in a workshop. It cost me around 250€ because the mechanic suggested replacing the radiator itself. A car radiator is like a lung, you can live with one, but I prefer two.

Thanks for the advice! It does sound like the speed sensor is the culprit. I took it to a mechanic, and indeed it was the speed sensor. The repair cost me 250€. The radiator is fine! Appreciate your help!
