I have an auto Jazz 2018 Exec. When I corner there's a slight grating or roughish noise somewhere in the front wheel area. It's not something caught I think mechanical. it does not last long and seems particular to how far the steering wheel is turned (say30 deg) and speed. difficult to describe really. Advice appreciated.

I would get it checked as could be dangerous if on a steered wheel.

Could be wheel bearing, worn driveshaft CV joint or even a broken coil spring rubbing on the tyre
