Ford F Hissing Sound Fuel Consumption

I'm experiencing an issue with my 2022 Ford F hybrid. I've noticed a significant increase in fuel consumption, the check engine light is on, and there's a loud hissing sound from the engine bay when I accelerate. I suspect an air intake leak. Given the mileage of 177839 km, could this point towards a degraded intake hose?

I had a similar issue with my old 2018 Honda Civic: higher fuel consumption and a hissing sound. Have you checked the throttle body for any visible cracks or loose connections? It might be a simple fix, but I'm not sure.

Thank you for your insight. I'll inspect the throttle body. However, could a leak in the vacuum hose connected to the turbocharger manifest with these symptoms? I'm trying to narrow down the possibilities.

It's hard to say for certain without a proper diagnosis, but it sounds like our cars faced the same issue. With those symptoms, I would recommend taking it to a workshop.

I appreciate the advice. It was an intake hose that was leaking, as suspected. Repair cost was 100€. Thank you for your help!
