Grinding or squealing when you brake

Usually worn brake pads. Grinding can mean the pads are down to metal and damaging the discs. Get it checked soon.

Squealing when you start or turn on the aircon

Often a worn or loose drive belt.

Knocking or clunking over bumps

Usually worn suspension parts such as bushes, links, ball joints or shocks.

Clicking when turning sharply

Often a worn CV joint on front-wheel-drive cars.

Knocking or ticking from the engine

Can be low oil, a valve train problem or something more serious. Check your oil level and get it diagnosed.

Hissing under the bonnet

Can be a coolant or vacuum leak. If the temperature gauge rises, stop driving.

Rattling from underneath

Often a loose heat shield or an exhaust problem.
