Car noises and possible cause/s. 1. Whereas worn brake pads screech, worn rotors and pads combi do screech too. It's important to get the pads replaced on time before they cost you the rotors/ discs as well.

A rattle can also be caused by a stretched timing chain or worn chain tensioner. Either way, get it checked before your engine is wrecked.

If humming doesn't change when you turn the wheel, chances are the rear wheel bearing is kaput. In an AWD equipped vehicle, the bearings inside the differential might be worn out

Some of the features you may be having on your car but you haven't/don't know how to use. 1. cruise control (CC). This feature allows you to set desired speed on manual & automatic cars. Most cars will allow this feature on speeds higher than 50kph or 60kph
2. Adaptive cruise control (ACC). This feature allows cruise control (set desired speed) plus it adjusts the speed depending on the speed of the car in front of you, without going over the set speed. It is applicable in urban and highway driving in most cars.
3. Auto hold (Automatic Electric parking/handbrake).This feature (when ON) engages parking brake automatically every time the car comes to a halt using the service (leg)brake)eg. Traffic lights, parking lot etc. It disengages with the touch of accelerator. Perfect in city traffic
