Frequently Asked Questions
How often should I service my car?
Most manufacturers recommend servicing your car every 10,000–15,000 km or every 6–12 months, whichever comes first. Regular servicing helps maintain performance and prevent costly repairs.
Do I need to service my car if it's running fine?
Yes! Regular servicing prevents hidden issues from becoming major (and expensive) problems. It also keeps your car safe and maintains its resale value.
Some common signs your car may need repairs:
• Strange noises (squealing, grinding, knocking)
• Dashboard warning lights staying on
• Vibrations or pulling when braking
• Difficulty starting the engine
• Unusual exhaust smoke
Why is my check engine light on?
A check engine light could indicate anything from a minor sensor issue to a serious engine problem. We recommend bringing your car in for a diagnostic scan as soon as possible.
