Grinding noise when braking

Metal-on-metal grinding almost always means the friction material is gone and the pad backing plate is cutting into the disc.

Stop driving

Steering wheel shakes when braking

A shudder felt through the wheel under braking is thickness variation in the front discs, not 'warping' in the heat-bend sense.

Car pulls to one side

A steady pull on a flat road is alignment, tyre pressure or a dragging brake. Which one depends on whether it happens only under braking.

Fix this week

Check engine light is on

The light only tells you a monitor failed. Read the code first — a $25 scanner turns a guess into a diagnosis.

Fix this week

Car won't start and just clicks

A single loud click with no crank points at the starter circuit; rapid clicking points at low battery voltage.

Stop driving

Battery warning light on while driving

The battery light is a charging-system light. The car is running on stored battery power and will stall once it is empty.

Stop driving

Engine is overheating

Coolant temperature above normal means heat is not leaving the engine. Continued driving risks a warped head and a bill ten times bigger.

Stop driving

Humming or droning noise while driving

A drone that rises with road speed and changes when you steer is a wheel bearing. If it stays identical while steering, look at tyres.

Fix this week

Air conditioning not blowing cold

Almost always refrigerant loss through a slow leak, but a blocked cabin filter or dead compressor clutch feels the same from the driver's seat.

Monitor

Clutch is slipping

Revs rise faster than road speed under load. A slipping clutch never recovers — it only gets worse and can damage the flywheel.

Fix this week

Car keeps bouncing after bumps

More than one rebound after a bump means the dampers are no longer controlling the springs.

Fix this week

Rough or shaky idle

A shake at idle that clears under load is usually a misfire, a vacuum leak or collapsed engine mounts.

Fix this week

Burning smell from the engine bay

Identify the smell: oil on the manifold is sharp and acrid, coolant is sweet, and burnt clutch or brakes is pungent.

Stop driving

Headlights dim or flickering

Dimming that follows engine speed points at charging or earth problems, not the bulbs.
