Ford F Hybrid engine start failure

I had a similar problem with my old 2016 BMW 3 series with a gasoline engine. The symptoms sound familiar. Did you check the battery cable connections? That fixed it for me. Let me know if that helps!

Thanks for the suggestion. Can you give me more details on how to check the cable connections properly? What should I look for?

Sure. With my BMW, the connections looked fine at first, but they were a bit corroded underneath. I disconnected them, cleaned them with a wire brush, and made sure they were tight. If that doesn't work, it might be something more serious like an ECU issue, and then you'd probably need to visit a workshop.

Thanks for your help. The battery cable connections were the problem. Cleaning and re-tightening them fixed it. The repair cost 155€.
