How To Know When It’s Time for a General Car Service

Life gets busy, and car servicing can easily slip down the priority list. But ignoring your vehicle’s early warning signs is a gamble that can end in costly repairs or a sudden breakdown. Whether you’re commuting daily or only using your vehicle on weekends, every car needs regular attention to stay reliable, efficient and safe. General car servicing isn’t just about fixing problems but preventing them.

Here are a few clear signs that your car may be due for a service. Paying attention to these cues helps ensure your car stays in top condition and supports your long-term driving confidence.

Your Dashboard Lights Are Trying To Tell You Something

Most modern vehicles have sensors that detect problems before they become serious. Ignoring the signs that your car needs a service could lead to more than just inconvenience.

• A “check engine” light may indicate anything from a faulty oxygen sensor to an engine misfire.
• Oil pressure, battery and temperature warnings could signal urgent mechanical issues.
• Even if the lights flicker or seem to reset, underlying problems may persist until properly diagnosed.

A general car service includes an electronic scan that identifies and resolves fault codes before they escalate.

Strange Sounds or Vibrations While Driving Aren’t Just Annoying

Many drivers wonder: “When do I need to service my car?” The answer often depends on your vehicle’s age, usage, and manufacturer guidelines. These early warnings should never be dismissed.

• High-pitched squeals when braking may mean worn-out brake pads.
• Grinding noises could be related to issues with bearings, suspension or the gearbox.
• Steering wheel vibrations often indicate wheel balancing or alignment problems.

These sensations are rarely minor. A mechanic can isolate the issue during a routine inspection and resolve it before it affects your safety or leads to component failure.

Reduced Fuel Efficiency That Doesn’t Match Your Driving Habits

If you’ve noticed you’re spending more at the pump but your driving habits haven’t changed, your car could be working harder than it should. This often points to wear or inefficiencies that affect performance.

• Dirty air filters reduce oxygen intake, forcing the engine to burn more fuel.
• Faulty spark plugs can cause incomplete combustion and lowered efficiency.
• Under-inflated tyres or misaligned wheels increase rolling resistance.

A standard car service typically includes checks of these systems and adjustments that restore your car’s optimal fuel economy.

You’ve Reached Your Car Manufacturer’s Recommended Service Interval

Noticing that you’re filling up more often, despite driving the same routes? That’s a red flag that your car could be underperforming. It’s also one of the clearest indicators to consider when you service your car, especially if you haven’t done so in a while.

• Many cars require servicing every 10,000 to 15,000 km or every 12 months—whichever comes first.
• Some components (e.g. engine oil, filters, coolant) degrade over time regardless of mileage.
• Skipping scheduled maintenance can void your warranty and lead to reduced resale value.

Following your service logbook keeps your vehicle running smoothly and protects its future value.

Brakes Feel Soft, Unresponsive, or Make Noise

Braking performance is critical, and any changes should be taken seriously. If your brakes feel different, don’t wait until they fail to take action.

• A spongy pedal can be caused by air in the brake lines or worn seals.
• Squealing or grinding noises indicate that brake pads are worn or rotors are scored.
• Uneven braking or pulling to one side could mean a calliper or hydraulic issue.

Regular servicing includes a complete brake inspection, helping ensure your vehicle can stop safely when it matters most.

The Engine Is Stalling, Misfiring, or Running Rough

Your car’s engine should run smoothly and predictably. If it starts to hesitate, stall or lose power, there’s likely a problem developing under the bonnet.

• Misfiring is often linked to ignition issues like faulty coils or plugs.
• Stalling could be caused by fuel delivery faults or throttle body problems.
• Rough idling may suggest dirty injectors or airflow sensor errors.

These issues can be addressed during a general service before they lead to full-blown breakdowns or loss of driveability.

Oil Is Leaking or Looks Dark & Sludgy

Oil isn’t just about lubrication—it’s essential to cooling, cleaning and protecting your engine. But over time, oil degrades and becomes less effective.

• If your oil looks thick, gritty, or black, it’s past its prime and could cause engine wear.
• Leaking oil often points to seals, gaskets or the sump plug issues.
• Low oil levels can lead to overheating, friction damage and catastrophic failure.

A general car service typically includes an oil and filter change, inspection for visible leaks, and fluid condition.

It’s Been Over 12 Months Since Your Last Service

Even if your car seems fine and you don’t drive often, servicing once a year is essential. Time, just like kilometres, contributes to wear and tear.

• Rubber hoses, belts and seals can dry out and crack with age.
• Coolant and brake fluids absorb moisture and lose effectiveness.
• Batteries degrade over time and may show no signs until they fail.

Staying on top of annual servicing prevents hidden issues from catching you off guard when you least expect them.
