Routine car maintenance is essential for your vehicle’s longevity, safety, and optimal performance. While some maintenance needs are easy to spot, others can go unnoticed until they become costly or even dangerous. By paying attention to a few key indicators, you can catch issues early and ensure your car stays in top condition. Here’s a look at the top signs it’s time for a professional car service.
1. Dashboard Warning Lights Are On

With our attention to detail and commitment to excellence, you can trust DLP Autos to take care of all your automotive needs with precision and expertise.
One of the clearest signs that your car needs attention is when dashboard warning lights appear. These lights are part of your car’s onboard diagnostic system, alerting you to potential issues with various components:
- Check Engine Light: This can indicate anything from a loose gas cap to a serious engine issue. If the light is flashing, it suggests a more urgent problem.
- ABS (Anti-lock Braking System) Light: This light points to issues with your braking system, which could impact your safety on the road.
- Oil Pressure Light: When this light appears, it means there may be a problem with the oil level or oil pressure in your engine, which can lead to serious engine damage if ignored.
Dashboard lights should never be ignored. If any appear, it’s a sign to book a car service promptly.
2. Unusual Sounds or Noises
New sounds coming from your car are often an indication of a problem.
- Squealing or Grinding Brakes: If you hear squealing, it’s likely time to replace the brake pads. Grinding sounds, however, could mean the brakes are more seriously worn down.
- Knocking or Pinging in the Engine: This could indicate engine trouble, often caused by issues with fuel quality, ignition timing, or other internal problems.
- Rattling or Clunking in the Suspension: If you hear rattling when going over bumps, it could mean parts of your suspension system need attention.
- Humming or Whining from Under the Hood: A humming noise can come from worn bearings, the transmission, or the alternator. Whining can indicate a slipping belt or low-power steering fluid.
When you notice any unusual sounds, book a professional car service to diagnose and fix the issue.
3. Reduced Fuel Efficiency
If you find yourself filling up your tank more frequently than usual, it could be a sign that something is wrong with your car’s performance. Common causes of decreased fuel efficiency include:
- Dirty or Clogged Fuel Injectors: These reduce the fuel flow, leading to inefficient combustion.
- Spark Plug Issues: Faulty spark plugs can result in incomplete fuel combustion, wasting fuel.
- Incorrect Tire Pressure: Underinflated tires increase friction on the road, which can lead to higher fuel consumption.
A professional service can identify the cause of the reduced fuel efficiency and help restore your car’s performance.
4. Rough or unstable idling
If your car idles roughly or vibrates excessively when you’re stopped, this can signal issues with several components, such as:
- Fuel System Problems: Clogged fuel filters or dirty fuel injectors can prevent your engine from getting the fuel it needs.
- Air Intake Issues: A dirty air filter or faulty sensors can disrupt the air-fuel mixture in the engine.
- Ignition System Problems: Faulty spark plugs or ignition coils can cause your engine to misfire, leading to rough idling.
A rough idle is often the sign of an underlying problem that should be addressed by a professional mechanic.
5. Strange Smells Coming from Your Vehicle
Unusual smells coming from your car are a strong sign that it’s time for a professional inspection.
- Burning Smell: This could be caused by overheated brakes or clutches or by an electrical short. It could also mean leaking oil is burning in the engine.
- Sweet smell: This smell may indicate a coolant leak, which can lead to engine overheating if not addressed.
- Gas Smell: Smelling gas inside or around your car suggests there could be a fuel leak, which is dangerous and should be inspected immediately.
Any odd odours should prompt you to visit a professional garage as soon as possible to prevent more significant issues.
6. Difficulty Starting the Engine
If your car is struggling to start, especially in normal weather conditions, this is a sign of trouble. Possible causes include:
- Battery Issues: A weak or failing battery is a common cause of starting problems.
- Fuel System Problems: Clogged fuel filters or a faulty fuel pump can prevent the engine from receiving fuel.
- Ignition Issues: Faulty spark plugs, ignition coils, or a worn starter motor can make it difficult to start your car.
A professional mechanic can diagnose the root cause and provide the necessary repairs or replacements.
7. Excessive exhaust smoke
The colour and amount of exhaust smoke can reveal a lot about your car’s condition.
- Blue Smoke: This usually indicates burning oil, which can mean there’s an issue with the engine or gaskets.
- White Smoke: If the smoke is thick and white, it could mean coolant is leaking into the engine.
- Black Smoke: A black exhaust can indicate that the engine is burning too much fuel, possibly due to a dirty air filter, faulty fuel injectors, or another issue.
If you notice more exhaust smoke than usual, it’s a good idea to have a professional take a look.
8. Fluid Leaks Under the Car
Seeing fluid pooling under your car is never a good sign. Different fluids signal different issues:
- Oil Leak: Oil leaks can be due to degraded gaskets, loose oil pan bolts, or a faulty oil filter.
- Coolant leak: If you notice a bright green, orange, or pink fluid, it’s likely coolant, which could lead to overheating if not addressed.
- Brake Fluid Leak: This fluid is usually yellow and can indicate an issue with the brake lines or callipers.
Any leaks under your car should be checked out by a professional as soon as possible.
9. Vibrations While Driving
Unusual vibrations while driving often indicate problems that require attention.
- Unbalanced Tires: If your tires are unbalanced, it can lead to a noticeable vibration, especially at high speeds.
- Brake Problems: Vibrations when braking may indicate warped brake rotors or worn pads.
- Suspension Issues: Problems with the suspension, such as worn-out shock absorbers, can also cause your car to vibrate while in motion.
If you’re experiencing unexplained vibrations, schedule a service appointment to have your car inspected.
10. Loss of power or acceleration
If your car struggles to accelerate or feels sluggish, there may be an issue with the engine, transmission, or other components.
- Engine Trouble: Problems with the engine, such as a clogged air filter or fuel injector, can limit power.
- Transmission Issues: A worn or failing transmission can also cause your car to lose power or accelerate poorly.
- Exhaust System Problems: A clogged catalytic converter can restrict exhaust flow, reducing engine performance.
A professional service can diagnose the underlying cause and restore your car’s responsiveness.
Our trained technicians recommend scheduling service if you notice any unusual noises coming from your engine, experience a decrease in fuel efficiency, or detect a strange odour inside your vehicle. Additionally, visible leaks, dashboard warning lights, or a rough idle are all indicators that your car may benefit from a thorough inspection by professionals.
