When you’re on the road, whether it’s hauling a full load across state lines or delivering essential goods locally, your truck is more than just a vehicle. It’s your livelihood. However, no matter how well-maintained your truck is, issues can arise without warning—especially in the middle of a long haul.

As a trucker or fleet manager, understanding the common emergency truck repairs you could face—and knowing how to prevent them—can mean the difference between a minor inconvenience and a major delay that costs you both time and money.

At Decker 24 HR Truck and Trailer, we’ve seen it all. As a trusted name in emergency roadside assistance and truck maintenance, we understand the frustration that comes with unexpected repairs. That’s why we’ve put together this comprehensive guide to the 7 most common emergency truck repairs and how you can avoid them, keeping you on the road and rolling safely.

1. Tire Blowouts: The Unpredictable Nightmare

Tire blowouts are one of the most common—and dangerous—emergencies for truckers. A blowout at highway speeds can result in loss of control, costly damages, and potential accidents. Unfortunately, tire blowouts are often unpredictable, but there are ways to reduce your risk.

How to Prevent It:

Regular Inspections: Inspect your tires before every trip. Look for cracks, bulges, or uneven wear.
Tire Pressure Monitoring Systems (TPMS): Many trucks today come equipped with TPMS to help monitor tire pressure in real-time. If you’re not already using one, it’s time to invest.
Proper Inflation: Over-inflation or under-inflation can cause excessive heat buildup, which increases the risk of a blowout. Ensure your tires are inflated to the manufacturer’s recommended levels.
Replace Worn Tires: If your tread is worn down or your tires are showing signs of aging, replace them before your next haul. It may cost you upfront, but it will save you in the long run.

How Decker 24 HR Can Help:

Our 24/7 roadside service ensures that if you do experience a tire blowout, we’re ready to come to your location and replace it. Whether it’s a quick tire swap or a full repair, we’ll get you back on the road as soon as possible.

2. Brake Failures: The Life-Saving System You Can’t Afford to Ignore

Brakes are arguably the most important safety feature of any truck. When they fail, it’s not just an inconvenience—it’s a life-threatening emergency. Brake failure can occur due to a number of reasons, including worn-out brake pads, air system leaks, or overheating.

How to Prevent It:

Routine Inspections: Ensure your brake pads, shoes, and air systems are inspected regularly. Decreased brake pad thickness is a sure sign it’s time for replacement.
Proper Brake Maintenance: The air brake system in particular needs to be checked for leaks and proper pressure. A malfunctioning air compressor can lead to brake failure, so have it checked regularly.
Don’t Overload the Truck: Carrying excessive weight increases stress on the braking system and can lead to quicker wear.

How Decker 24 HR Can Help:

Our skilled technicians are trained to handle brake system diagnostics and repairs on-site. If your brakes fail while you're on the road, we’ll quickly get to your location and either repair or replace the faulty parts.

3. Electrical System Issues: The Silent Culprit Behind Many Failures

The electrical system in your truck powers everything from lights and gauges to the engine and battery. Electrical problems can manifest in many ways, such as a dead battery, faulty alternators, or wiring issues. These problems can cause significant delays and can be difficult to diagnose on your own.

How to Prevent It:

Check Your Battery Regularly: Ensure your truck’s battery terminals are clean and free from corrosion. Test the battery regularly to ensure it has enough charge to power your truck.
Inspect Alternators and Wiring: Alternators and wiring wear out over time, especially under the strain of long-haul driving. Regular checks can catch problems early.
Keep Connections Clean and Tight: Loose connections can lead to intermittent electrical failures that might leave you stranded.

How Decker 24 HR Can Help:

Decker 24 HR’s mobile service fleet can perform a range of electrical system diagnostics and repairs. If your truck’s battery, alternator, or wiring fails on the road, we’ll be there to fix it quickly and efficiently.

4. Engine Overheating: Keeping Your Cool Under Pressure

Overheating is one of the most common engine problems, and it often strikes when you least expect it. Whether you’re in the middle of a summer heatwave or climbing a steep mountain pass, your engine can overheat due to low coolant levels, a broken radiator fan, or a clogged coolant line.

How to Prevent It:

Check Coolant Levels: Make sure your coolant levels are topped off and inspect for leaks. Running low on coolant can cause your engine to overheat.
Inspect the Radiator: Look for signs of damage or corrosion on the radiator. Ensure that the radiator fan is operating correctly.
Monitor Temperature: Keep an eye on your engine temperature gauge. If it begins to rise into the danger zone, pull over immediately to avoid further damage.

How Decker 24 HR Can Help:

Our mobile units are equipped with tools to perform cooling system checks and repairs. If your truck is overheating, we can diagnose the issue, whether it’s a coolant leak, a faulty fan, or a clogged radiator, and get you back on the road.

5. Suspension Problems: A Bumpy Ride That Can Lead to Major Damage

The suspension system in your truck is responsible for providing a smooth ride, even when hauling heavy loads. If the suspension begins to fail—whether through worn-out shock absorbers, broken springs, or leaking air bags—it can affect the handling and safety of your truck, particularly when navigating rough roads or inclement weather.

How to Prevent It:

Regular Suspension Inspections: Have your suspension system checked regularly, especially if you notice unusual noises or rough rides.
Check for Leaks: Air suspensions, in particular, can develop leaks over time. Keeping an eye out for signs of leaks will help you catch problems early.
Avoid Overloading: Carrying excessive weight can place unnecessary strain on your suspension system.

How Decker 24 HR Can Help:

Our roadside technicians are skilled in suspension system repairs and can perform diagnostic checks if your ride feels “off.” Whether it’s a quick fix or a major replacement, we’ll make sure your truck is safe and stable again.

6. Faulty Air Lines (For Trailers): Ensuring Safe and Secure Braking

For trucks with trailers, faulty air lines are a serious concern. These lines carry the compressed air that powers the braking system, and any leaks or malfunctions can cause the trailer brakes to fail. A damaged air line can also affect other systems like the suspension or air-ride seat.

How to Prevent It:

Regular Inspection: Check your air lines for visible signs of wear, cracking, or damage. Look out for leaks or areas where air may be escaping.
Keep Connections Clean and Secure: Ensure that air lines are properly connected and free from dirt, which can cause blockages.
Replace Worn Air Lines: Air lines should be replaced as needed, especially when they show visible wear or are exposed to extreme conditions.

How Decker 24 HR Can Help:

Decker 24 HR specializes in air line repairs and replacements for both trucks and trailers. If you experience a problem with your air lines, we’re ready to fix it quickly and get your braking system functioning properly again.

7. Battery/Starter Failures: Getting the Engine to Turn Over

When your truck’s engine doesn’t start, it could be due to a dead battery, a faulty starter motor, or a wiring issue. This can leave you stranded at the most inconvenient times, especially if you’re far from a repair shop.

How to Prevent It:

Test Your Battery: Regularly test your battery to ensure it has sufficient charge. Most batteries last 3–5 years, but if you’re having trouble starting your engine, it may be time to replace it.
Inspect the Starter: The starter motor can wear out over time. If your truck is struggling to start, it may be a sign that the starter is failing.
Check Connections: Loose or corroded battery terminals can prevent proper power flow to the starter motor.

How Decker 24 HR Can Help:

We offer quick battery replacement and starter motor diagnostics and repairs. If you’re stuck with a non-starting truck, call Decker 24 HR and we’ll send a technician out to get your engine turning over in no time.
