Vehicle maintenance: Common car noises and their causes

Ignoring unusual noises from a vehicle can lead to significant repair costs and safety risks. Identifying specific sounds can help diagnose underlying mechanical issues before they escalate.

Common warning signs include:

• Braking noises: Squealing or grinding sounds during braking often indicate worn brake pads or issues with the brake discs.

• Engine sounds: Rattling or knocking noises may signal low engine oil levels, old oil, or internal component failure.

• Steering sounds: Squeaking or whistling while turning can be caused by low power steering fluid, steering system malfunctions, or loose belts, which may eventually make steering difficult.

• Suspension sounds: Thumping or knocking sounds when driving over bumps or speed breakers often point to worn shock absorbers or suspension components, affecting vehicle balance and control.

• Air conditioning sounds: Unusual noises when the AC is activated may stem from a faulty compressor or loose belts.
