If your car is screeching when you turn a corner, it's likely due to a problem with your brakes. When you turn a corner, your car's weight shifts and the brakes have to work harder to stop the car. If the brakes are worn out or not properly adjusted, they may start to squeal or screech.
If you hear a screeching noise when you turn a corner, it's important to have your brakes checked as soon as possible. Brakes are a vital safety feature on any vehicle and if they're not working properly, it could put you and others at risk.
