Let’s explore some of the most common reasons cars can break down and how to avoid them
There's nothing worse than the frustration of a breakdown, especially when you're stranded on the side of the road. You may be asking “why has my car broken down?”, not knowing where to start in diagnosing the problem.
While unexpected car troubles can happen to anyone, many breakdowns are preventable.
Let’s explore some of the most common reasons cars can break down and how to avoid them, ensuring you stay safe on the road. Brought to you by Aviva in conjunction with Carzone.ie
1. A dead battery
We’ve all been caught out with a dead battery at one time or another. They are relatively easy to fix with jumper cables and a friendly neighbour, but to avoid your battery tapping out in the first place, consider:
- Regular replacement: Check your battery's condition regularly and replace it every few years as recommended by the manufacturer.
- Avoid draining: Always remember to turn off your lights and accessories when not in use and avoid leaving the car idle for long periods.
2. Flat or damaged tyres
Flat tyres are pretty common and can often happen out of nowhere. But most of the time, regular maintenance can help prevent this.
- Regular inspection: Check your tyre pressure regularly and inspect them for signs of wear or damage. Your car may alert you when a tyre is damaged or not inflated to the recommended pressure – always make sure to check them as soon as you notice any changes.
- Correct inflation: Keep your tyres inflated to the recommended pressure (you can find this online or in your car’s user manual) to avoid blowouts.
3. An overheated engine
An overheated engine can lead to serious damage if not addressed promptly. Always remember to check:
- Coolant levels: Top up your coolant regularly.
- Regular servicing: During your regular car service, make sure the cooling system is inspected and serviced.
4. Fuel issues
Ignored your fuel light for too long? Running out of fuel or using the wrong type causes many breakdowns on the road. Always keep an eye on your fuel gauge and remember to never stray from your recommended fuel type.
5. Alternator failure
The alternator is responsible for charging the battery and powering electrical systems in your car, making it a very important piece of machinery. You can avoid issues by regularly checking your battery and alternator, and taking action as soon as you notice things like dimming lights.
6. Ignition system failure
Issues with the ignition system can leave you stranded unable to start your car.
- Key maintenance: Keep the ignition components on your key clean and lubricated to prevent wear and corrosion. If you use a fob, make sure its battery is charged and it’s in full working order before any big trip.
- Replace worn parts: Be sure to replace spark plugs, ignition coils, and other components as soon as they are needed.
Transmission problems
Transmission issues can cause your car to stall or lose power. You can avoid problems with this part of your car by:
- Fluid checks: Regularly check your car’s transmission fluid levels and top up or replace as needed.
- Smooth driving: Avoid sudden acceleration, excessive braking, and towing heavy loads to reduce strain on the transmission.
8. Brake failure
Brake failure can be catastrophic, so it’s essential that your car’s brakes are in full working order at all times. Have them inspected regularly and check your brake fluid levels often.
9. Issues with the electrical system
Electrical car issues can result in lots of different issues and can be hard to pinpoint and fix. Generally, you can mitigate electrical issues by checking your battery regularly and replacing any blown fuses quickly.
10. General lack of maintenance
Always keep up to date with your services and replace your oil and filters regularly. Any issues should always be addressed as soon as you notice them – don't leave it to get worse.
By being proactive and attentive to your vehicle's maintenance needs, you can significantly reduce the risk of breakdowns and ensure smooth, trouble-free driving.
