GrandlandX Hybrid ECU Error

I also own a GrandlandX hybrid. I had similar issues, although my mileage was lower. Have you checked the fault codes? It could be a number of things, but relay problems are quite common on these.

Thanks for your reply. Yes, I checked the error memory, and it points towards the engine control unit. Do you remember what the eventual repair was in your case? I'm trying to get an idea of what I'm in for.

Yes, mine was the main relay too, which caused the ECU to throw errors. I'd suggest getting it checked at a workshop to confirm. It should be a pretty straightforward fix, though.

Thanks. I had it checked, and it was indeed the main relay. Repair cost 120€. Appreciate the help.
