Interesting! I haven't checked the cable and plug connections yet, but I will definitely take a look. Where exactly should I be looking? Is it easy to access, or do I need to remove a bunch of stuff to get to it?

I'm not a mechanic, so take my advice with a grain of salt. Definitely check those connections. I’d recommend taking it to a workshop, because it requires specific knowledge. They should be able to diagnose and fix it quickly. It was a defective cable in my instance as well. The repair was only around 95€, so it shouldn’t break the bank.

Thanks so much for the advice! I checked the fuel pump cable and plug connections, and everything seemed fine. I brought the car to my mechanic, and he found the defective cable as well. It cost me 95€ too! You were spot on! Appreciate the help!

Sounds familiar! I had similar issues with my Grandeur, though it's not a hybrid. Engine stalling and rough running were the first signs. Have you checked the fuel pump's cable and plug connections? That was the culprit in my case.
