If your car is shaking or vibrating while idling, driving, or braking, it may point to problems in the tyres, wheels, engine, brakes, or suspension. Vibrations can range from minor annoyances to serious safety issues, depending on the cause. Getting this checked early helps prevent further damage and keeps driving safe.

What does it mean if a car is shaking or vibrating?

Shaking or vibrating usually means something is unbalanced, worn, or misfiring. It can happen at idle, at certain speeds, or when braking. The source may be mechanical, electrical, or related to wheel alignment and balance.

Common causes of car shaking

• Unbalanced or damaged wheels and tyres
• Worn suspension or steering components
• Warped brake rotors causing vibration when braking
• Engine misfires from faulty spark plugs, coils, or injectors
• Loose or damaged engine or transmission mounts
• Driveshaft or CV joint wear

Why do you need to fix this problem quickly?

Shaking and vibrations reduce comfort and can quickly lead to tyre, suspension, or brake damage. If caused by engine or driveline faults, ignoring the issue may result in breakdowns or unsafe driving conditions.

How do you know when to get it checked?

Signs include:

• Steering wheel vibration at certain speeds
• Car shakes more when braking
• Engine shakes or feels rough when idling
• Unusual noises such as knocking, clunking, or rattling
• Shaking worsens as speed increases

What happens during an assessment?

A mechanic will:

1. Test drive the car to replicate the vibration
2. Inspect tyres for balance, wear, or damage
3. Check wheel alignment and suspension components
4. Inspect brake rotors and pads
5. Check for engine misfires and inspect mounts
6. Examine driveshafts and CV joints if necessary

How much does it cost to fix?

Costs vary depending on the cause. Wheel balancing typically costs $60–$120. Brake rotor machining or replacement ranges from $250–$600. Suspension, driveline, or engine repairs can cost $400–$2,000+.

Is it unsafe to drive with vibrations?

Yes. While some vibrations may be minor, they can signal serious faults in brakes, tyres, or suspension. Driving with persistent shaking can compromise control and safety, so it should be inspected immediately.
