Experienced mechanics or car technicians have developed the ability to diagnose car problems through their sense of sight, smell, sound, and feel. However, the same cannot be said for most drivers or car owners.

Being able to detect basic vehicle issues with one’s senses allow individuals to bring in their vehicles immediately for service or checks once they sense something out of the ordinary, than to wait for the regulatory mileage to prevent bigger car problems. Drivers and car owners who are able to describe and locate potential problems can also help mechanics perform a better and more accurate diagnosis of the vehicle.

The good news is, drivers or car owners can easily detect car problems with their sense of sight, smell, sound, and feel by following these tips:

  1. Sight

Windshield: Large unwiped areas on the windscreen indicate that wipers are due for replacing Foggy windscreen and windows could mean the cabin filter is clogged causing poor air flow

Leakage: Fluid or liquid puddles underneath the car may indicate a leak somewhere. It is important to have the driver remember the colour of the fluid. Common colors are:

  • Black or dark brown– engine oil leak
  • Red or pink – transmission oil leak
  • Yellow to brown – brake fluid leak
  • Green or blue – coolant or anti-freeze leak
  • Brown with rainbow sheen – petrol leak
  • Clear and odourless – most likely condensation from the air conditioning system

Higher than usual fuel consumption: This can be a sign that the air filter is clogged, preventing proper oxygen flow into the engine

Tires: Cracks and balding on the surface of tires specify that the tires are overworn and overused


  1. Smell

  • The smell of exhaust, musky or damp odors in the car are signs of a clogged cabin filter that needs to be replaced
  • Any burning, gas, petrol, rotten egg or unusual sweet smells could lead to indications of potential engine-related problems or a leak


  1. Sound

Wipers: Screeching and scratching noises indicate that the wipers are at the end of its lifespan and need replacing

Battery: A slower crank when starting the engine is a sign that the car battery is running low

Brake: A high-pitched metal screeching sound while braking or slowing down

are indications that the brake pads are wearing out

Tire: A rattling sound when driving may indicate loose screws on the tires or loose tire cover


  1. Feel

Air conditioning: Reduced coldness of the airconditioning (AC) may indicate a clogged cabin filter or problems with the AC system

Tire: Vibrations felt through the steering wheel may indicate the tire alignment is off. If the car tends to steer or pull towards one side when driving, it may be an indicator of over or under inflated tires, or the tire alignment being off

Road safety starts with you

Safer cars lead to safer roads. Being able to detect vehicle problems on your own creates a more informed community of drivers and car owners, and helps in reducing the risks of future accidents caused by undetected car troubles.
