Why is the Ford Fiesta losing power while driving at high speeds?

I have a 2015 Ford Fiesta and recently I've noticed that while driving on the highway at high speeds, the car starts to lose power. This has happened a few times now and it's a bit concerning. What could be causing this issue and how can I fix it?

This could be caused by a few different things. It's possible that your fuel filter is clogged or your spark plugs need to be replaced. It's also possible that your transmission is slipping. I would recommend taking your car to a mechanic to have it diagnosed and fixed.

I had the same issue with my 2014 Ford Fiesta and it turned out to be a faulty fuel pump. I would suggest checking the fuel pump and replacing it if necessary.

I had this problem with my 2016 Ford Fiesta and it was a faulty throttle position sensor. That has since been replaced and I haven't had any issues since.
