Fiesta heavy steering

I had something similar with my Ford Focus, different setup though. Heavy steering and vibrations sound like what I went through. I thought it was alignment at first, but it ended up being the angle sensor. Have you thought about just replacing the sensor?

Thanks! Was your sensor issue intermittent at first? And did a diagnostic pinpoint the sensor, or was it more ruling things out?

Yeah, it was intermittent at first, which made it tricky. The sensor wasn't obviously the problem right away. But it gradually got worse, and the diagnostic readings started showing weird steering angle data, which led to replacing the sensor. Considering your Fiesta's age and mileage, a workshop visit might be a good call to check that sensor.

Thanks for the advice. I got the Fiesta checked out. The diagnostic confirmed the steering angle sensor had faulty coding, so I had to replace it and get the wheels aligned. Cost me 195€. Thanks for pointing me in the right direction!
