Cars rarely fail without warning. They usually tell you something is wrong well before it becomes serious, and the trick is knowing which signs can wait and which can’t.
Stop driving now
A few things genuinely mean pull over rather than carry on.
Red warning light. Red means stop. Oil pressure, engine temperature, brakes, charging system — driving on with a red light showing can turn a repair into a new engine. Amber means get it looked at soon; red means now.
Smoke or steam. Either way, stop and let it cool before you open anything.
Brakes that feel wrong. A soft or sinking pedal, a pedal that goes further than it used to, or a grinding noise when you brake. Not something to leave until the weekend.
Loss of steering feel, or the car pulling hard to one side under braking.
A burning smell. Could be oil on a hot exhaust, could be a slipping clutch, could be wiring. None of them improve by driving further.
Book it in soon
A squeal when braking usually means pads are getting low. A grinding noise means they’ve gone and you’re into the discs, which costs considerably more.
Knocking or clonking over bumps points at suspension or steering components — bushes, drop links, ball joints. Not usually urgent, but it affects handling and it will fail an MOT.
A whine or hum that changes with speed is often a wheel bearing. Cheap to fix early, awkward if it’s left.
Amber warning lights. Engine management, ABS, tyre pressure. The car will keep going, but something has recorded a fault and it’s worth knowing what before it becomes two faults.
Uneven tyre wear. Wearing on one edge points to alignment or suspension. Left alone, you’ll buy tyres more often than you should.
A vibration through the steering wheel at certain speeds — usually wheel balance, sometimes something more.
Worth mentioning next service
Slightly longer starting than usual. Often the battery, particularly on a car doing short journeys.
Air conditioning not as cold as it was. Normal gradual loss of refrigerant, easily recharged.
Clutch biting higher than it used to. Wear, and worth knowing about before it becomes a problem.
Any new noise, smell or behaviour that you’ve started getting used to. You know your car better than anyone. If something has changed and you’ve adapted your driving around it, that’s worth mentioning.
And don’t ignore the MOT advisories
Advisory items on an MOT are things that passed but won’t next year. They’re a free list of what needs doing over the following twelve months, and dealing with them as they come is cheaper and far less inconvenient than a fail.
If you’re not sure
Describe the noise. We’ll have heard it before.
We’re a family-run workshop on the Waterloo Industrial Estate in Bidford-on-Avon, and we’d rather look at something for nothing and tell you it’s fine than have you drive around worrying about it.
