Summer Driving: Common Vehicle Issues and How to Fix Them

As the temperature rises and we hit the road for holidays and day trips, your vehicle faces unique challenges during the summer months. At Warranty First, we're committed to keeping you informed about potential issues and empowering you with the knowledge to address them. Let's explore some common vehicle problems that crop up in the summer and provide practical solutions to keep you cruising comfortably.

Overheating Engines

The Problem:
Hot weather puts extra strain on your car's cooling system. When temperatures soar, the risk of your engine overheating increases significantly.

The Fix:

• Regularly check coolant levels and top up if necessary
• Inspect hoses and belts for signs of wear or cracking
• Ensure the radiator fan is functioning properly
• Consider a professional flush of the cooling system if it's been a while

Prevention is key. If your temperature gauge starts creeping into the red zone, pull over immediately and let the engine cool down before investigating further.

Tyre Troubles

The Problem:
Hot roads can cause tyre pressure to increase, potentially leading to blowouts. Underinflated tyres are also at risk of overheating.

The Fix:

• Check tyre pressure monthly and before long journeys
• Adjust pressure according to manufacturer recommendations
• Inspect tyres for signs of wear or damage

Remember, properly inflated tyres not only enhance safety but also improve fuel efficiency - a win-win for summer road trips.

Battery Drain

The Problem:
While cold weather is notorious for affecting batteries, extreme heat can be just as damaging, causing battery fluid to evaporate and internal components to degrade.

The Fix:

• Have your battery tested, especially if it's more than three years old
• Keep battery terminals clean and free from corrosion
• Ensure the battery is securely mounted
• Consider a battery maintainer for vehicles not used regularly

A well-maintained battery will help you avoid the frustration of being stranded with a car that won't start on a scorching summer day.

Air Conditioning Woes

The Problem:
Nothing ruins a summer drive quite like a malfunctioning air conditioning system. Reduced cooling efficiency or strange odours are common complaints.

The Fix:

• Regularly run the A/C system, even in cooler months, to keep it in good condition
• Replace the pollen filter annually
• If cooling seems weak, have the system checked for refrigerant leaks
• Address any unusual smells promptly, as they could indicate mould growth

A properly functioning A/C system isn't just about comfort - it also helps maintain driver alertness on long, hot journeys.

Brake System Issues

The Problem:
Summer heat can exacerbate existing brake problems, potentially leading to brake fade - a temporary loss of stopping power due to overheating.

The Fix:

• Have your brakes inspected regularly, especially before long trips
• Listen for any unusual noises when braking
• Be mindful of any changes in brake pedal feel
• Consider upgrading to high-performance brake pads if you frequently drive in mountainous areas

Remember, your brakes are crucial for your safety. Any concerns should be addressed promptly by a qualified mechanic.

Fuel System Complications

The Problem:
Hot weather can cause fuel to evaporate more quickly, potentially leading to vapour lock in older vehicles. Modern cars may experience reduced fuel efficiency.

The Fix:

• Keep your fuel tank at least quarter full to reduce the amount of air in the tank
• Use the recommended grade of fuel for your vehicle
• Consider fuel system cleaning services to remove deposits and improve efficiency
• Park in shaded areas when possible to keep fuel temperatures down

Maintaining your fuel system can help ensure smooth running and optimal efficiency during summer drives.

Paint and Interior Damage

The Problem:
Prolonged exposure to intense sunlight can fade paint, crack dashboard materials, and damage upholstery.

The Fix:

• Wash and wax your car regularly to protect the paint
• Use a quality sun shade when parking
• Consider applying UV-protective film to windows
• Use leather conditioner on seats to prevent cracking

Protecting your car's aesthetics not only keeps it looking great but also helps maintain its resale value.

Windscreen and Wiper Issues

The Problem:
Summer sun can exacerbate existing chips or cracks in your windscreen. Dry, hot weather can also cause wiper blades to deteriorate more quickly.

The Fix:

• Address any windscreen damage promptly to prevent spreading
• Replace wiper blades that show signs of wear or cracking
• Use windscreen washer fluid with bug-removing properties
• Consider applying a water-repellent treatment to your windscreen

Clear visibility is essential for safe driving, especially during sudden summer downpours.

Engine Oil Degradation

The Problem:

Extreme heat can cause engine oil to break down more quickly, reducing its effectiveness in lubricating and cooling engine components.

The Fix:

• Check oil levels regularly and top up if necessary
• Stick to the manufacturer's recommended oil change intervals
• Consider switching to a higher viscosity oil for summer driving (consult your owner's manual first)
• Be vigilant for any signs of oil leaks

Proper oil maintenance is crucial for your engine's longevity and performance, particularly in hot weather.

Electrical System Strain

The Problem:
Hot weather can put additional stress on your car's electrical system, potentially leading to component failures.

The Fix:

• Have your alternator checked if you notice dimming headlights or a weak battery
• Inspect wiring for signs of wear or damage
• Address any warning lights promptly
• Consider a full electrical system check if your car is older

A well-functioning electrical system ensures all your car's components work harmoniously, even in challenging conditions.

While summer driving brings its own set of challenges, being aware of potential issues and taking proactive steps can help ensure your journeys are safe and enjoyable. Regular maintenance and prompt attention to any developing problems are key to avoiding breakdowns and costly repairs.
