Modern vehicles rely heavily on electrical systems to power everything from your starter motor to headlights, infotainment systems, and safety features. So, when something in your vehicle’s electrical system goes wrong, it can be more than just a minor inconvenience — it can affect your safety, drivability, and day-to-day convenience.

At Hi-Mech Auto Solutions, we regularly diagnose and repair electrical faults in all makes and models — from European vehicles to utes and SUVs. If you’re experiencing strange warning lights, battery issues, or malfunctioning electronics, here’s a look at the most common electrical problems in cars and what you can do about them.

1. Dead Battery

The issue:
The most common electrical problem, a dead battery can prevent your vehicle from starting altogether. It could be caused by an old or worn-out battery, a faulty alternator, or simply leaving your lights on.

Symptoms:

• Clicking sound when turning the key
• Dimming lights or electronics not working
• Engine doesn’t crank or turn over

What to do:
Try jump-starting your vehicle to get back on the road, but make sure to have your battery and charging system tested. At Hi-Mech, we’ll check whether the issue lies with the battery itself or something else like the alternator or wiring.

2. Faulty Alternator

The issue:
The alternator is responsible for charging your battery and powering your vehicle’s electrical systems while the engine is running. If it starts to fail, your car may run for a while — but it won’t get far.

Symptoms:

• Battery warning light on the dash
• Flickering or dimming headlights
• Electrical accessories behaving erratically
• Flat battery even after recent replacement

What to do:
A simple alternator test at Hi-Mech can confirm if it’s time for a replacement. We’ll also check the drive belt and wiring connections to rule out related issues.

3. Blown Fuses

The issue:
Car fuses protect your vehicle’s circuits from overload. If something electrical stops working — like your power windows or interior lights — a blown fuse could be the culprit.

Symptoms:

• One or more electrical components stop working suddenly
• No power to accessories or features
• Visible break or discolouration in the fuse

What to do:
You can check your fuse box and replace a blown fuse with one of the same rating. But if fuses keep blowing repeatedly, there could be a deeper electrical fault, and it’s time to book in with Hi-Mech for a professional inspection.

4. Starter Motor Issues

The issue:
The starter motor gets your engine turning when you start your vehicle. If it’s faulty, you might be stranded — even if your battery is perfectly fine.

Symptoms:

• Clicking sound when turning the key
• No engine crank
• Lights and accessories work, but the engine doesn’t

What to do:
If your battery is healthy, but the engine won’t start, the starter motor or its wiring may be the issue. Our technicians at Hi-Mech Auto Solutions can quickly test and replace starter motors if needed.

5. Malfunctioning Sensors or Warning Lights

The issue:
Modern cars have dozens of sensors that feed data to your car’s computer. A single faulty sensor can cause warning lights to illuminate, or worse — affect how your car drives.

Symptoms:

• Check engine light stays on
• ABS, airbag, or traction control warning lights
• Poor fuel efficiency or performance changes

What to do:
Don’t ignore warning lights — even if the car still drives fine. Hi-Mech uses advanced diagnostics to scan your vehicle’s ECU (engine control unit), identify fault codes, and recommend the best solution.

6. Wiring and Electrical Shorts

The issue:
Wiring faults can be some of the most frustrating to track down. A damaged wire, poor earth connection, or moisture ingress can cause intermittent issues that are hard to reproduce.

Symptoms:

• Random warning lights or electrical glitches
• Burning smell or visible sparks
• Problems that come and go without clear cause

What to do:
Leave this one to the experts. Hi-Mech’s experienced auto electricians can inspect your vehicle’s wiring system, trace shorts or corrosion, and carry out precise repairs to ensure everything works safely and reliably.

As one of the most critical parts of your car when it comes to keeping your family safe in an emergency, it is essential that you keep your brakes in good condition. 

Even if there aren’t any warning signs that your brakes need a service, you should aim to have a professional take a close look at them every six months. By doing so, your mechanic can uncover potential issues, keep you safe on the road and help prevent costly brake repairs later on.

Between car brake services, it is important to stay aware of the potential warning signs that something could be wrong with your vehicle’s brake system.

Signs you should get a brake service

Brake warning light

A brake warning light appearing on your dash is the most obvious sign that something is wrong with your brakes. This light will usually appear as a circle with a ‘!’ in the middle and the word ‘BRAKE’ underneath or above. 

This can be resolved by something as simple as having a mechanic fill up the brake fluid, or it could be indicating a more serious problem. Either way, a car with the brake warning light showing is usually unsafe to drive, so you should give a professional a call as soon as possible. 

Unexpected noises

A major indicator that you may need a brake check up is unusual sounds when you apply pressure to the brake pedal. This could be grinding, squealing, crunching or screeching noises, which suggests that it may be time for your next brake service.

Slow brake response

If your brakes have an issue, you may notice that your vehicle is taking longer to stop than usual. In an emergency situation, a delay of less than a second can make all the difference. Similarly, if there is a change in brake pressure – such as the pedal feeling more difficult to press, or more slack – it is time to see the mechanic.

Shuddering or vibrations

If you are feeling vibrations or shaking when pressing on the brake pedal, this can be a cause for concern. Brake issues may also cause a shuddering sensation in the steering wheel when the brakes are applied. To maintain your safety on the road, you should book a brake inspection as soon as you can.

Burning smell

A burning smell while driving is often a sign of problems with a vehicle’s braking system. Whether the issue is with your brakes or not, burning smells while driving should always be assessed by a professional, ensuring there isn’t a larger issue that could prove catastrophic later.
