Steering feels more loose/wobbly when phone is connected to USB socket

    Hi everyone, this is my first post here. I have a 2017 Ford Fiesta. Steering is fine normally but for some reason, whenever I connect my phone to the car via the USB socket, to listen to my own music for example, the steering feels a lot more loose. The steering is normally loose when at low speeds to allow for maneuverability but at high speeds it should be less sensitive, which it is most of the time. But when the USB socket is used this is not exactly the case. I think maybe it's because the USB socket and the steering wheel are drawn from the same supply but I don't know. It's not exactly that big of a problem, but it definitely is noticeable. What do you think? Do I just have to accept this problem?

    I think diagnosis is the way to go.

    Are your tyres correctly inflated?

    The front tires are 32 psi and the back tires are 26 psi. 32 psi is the recommended pressure for comfort I think. So my back tires might be a little low.

    I just thought, too much pressure will make steering, 'nervous', too low will make it feel, 'vague'.
