FAQs

  • How often should I service my vehicle?

    Most manufacturers recommend servicing every 10,000–15,000km or every 6–12 months, whichever comes first — check your logbook for exact intervals. Vehicles used for towing, off-roading, or heavy loads may need more frequent attention. Regular servicing catches small issues early, keeps warranties valid, and helps ensure your vehicle stays safe and reliable on the road.

  • What are the signs my vehicle needs mechanical attention?

    Warning signs include strange engine noises, dashboard lights, poor fuel efficiency, reduced braking power, or unusual vibrations. These symptoms may point to underlying mechanical issues. Ignoring them can lead to further damage, safety risks, or breakdowns—so it’s best to have them inspected promptly.

  • Why is preventative maintenance important?

    Preventative maintenance helps identify and fix minor issues before they become major problems. It keeps the vehicle running efficiently, improves safety, and lowers long-term repair costs. Regular checks of fluids, belts, brakes, and suspension extend the life of your vehicle and minimise the risk of breakdowns.
