If you operate a semi-truck, you know how crucial it is to be ready for a breakdown while driving consistently. Even though breakdowns are occasionally unavoidable, being aware of the most typical types of semi-truck breakdowns will help you be vigilant and informed.

The reliability and quality of the parts are crucial for fleet trucks. Fleets may be quite productive when everything is running smoothly. By preventing failures, drivers may make deliveries quickly. When something goes wrong, such as a battery discharge, an oil leak, or a tire blowout, it can significantly slow down operations.

The secret to hitting your target's deadlines and keeping your rig on schedule as an operator is having the best tools to address common problems and knowing when to make needed repairs. This implies that you must be completely knowledgeable about the specifications for truck maintenance.

Let's examine some of the more typical truck repairs and truck electrical problems from the experts that fleet managers encounter.

Be Knowledgeable and Prevent Truck Breakdowns

You earn money while you are traveling. You can start counting the money as it drifts away while you're stranded on the side of the road while the semi is being repaired. Towing a semi-truck is not only expensive but also not the best option. Furthermore, semi-truck breakdowns frequently occur in unfavorable locations.

The more familiar you are with typical big rig breakdown issues, the more likely you are to spot them, stop them in their tracks, limit the damage, and save money. It concerns more than just the expense of repairs. It concerns your legal responsibility.

It's crucial to comprehend the most typical vehicle malfunctions so you can take preventative measures. You may stop breakdowns in their tracks by employing the appropriate tactics.

Top 10 Truck Breakdowns

Breakdowns on trucks may be very frustrating, especially if you're traveling through a remote area of the nation. No matter how cautious you are with your truck, breakdowns will still happen.

However, the most frequent reasons for truck breakdowns, according to the experts in logistics, are as follows.

1. Tire Blowouts

Truck tire blowouts are one of the most typical reasons for semi-truck breakdowns. One of the primary problems you should be aware of is a tire blowout because fleets travel great distances carrying massive amounts of commodities.

The technicians and service managers of truck carriers must, therefore, frequently inspect the tires on the fleet. This involves routine tire rotation, replacement of worn-out or balding tires, inspection of sidewall damage, air leaks, tread wear, tire pressure gauges, and vigilant tire recall monitoring. Drivers lose agility as tire tread wears down and are more prone to lose control of their cars. (This occurs frequently throughout bad weather.)

The tire itself could also have problems, such as tread separation, steel belt separation, improper puncture repair, insufficient preventative design features, unsuitability for the vehicle, retread issues, tires damaged during mounting, and/or manufacturing flaws. These problems are all tested, observable, and avoidable.

Fortunately, there are steps you may take to reduce these 18-wheeler tire blowouts:

• Regular maintenance and service: Tire rotations and routine maintenance will assist you in preventing blowouts. Inadequate tread depth, misaligned axles, and any other issues that could lead to a blowout on the road will be found during routine maintenance. You may feel secure knowing that your fleets will operate safely and effectively on the roads if you invest in those services.
• Preserving proper tire pressure: A tire blowout may be caused by overinflation and underinflation.
• To prevent issues, make sure you periodically check that pressure.
• Replace worn tires with new ones: When your tires begin to wear out, replace them. Older tires will likely have several problems that could result in a blowout.

Small actions like these can have a big impact on your fleet, resulting in more productivity, less downtime for maintenance, and greater assurance in the capabilities of your trucks. Additionally, drivers will be able to detect tire problems; a peculiar sound coming from the wheel wells should raise suspicions.

2. Brakes

Another significant factor in truck breakdowns is brake problems. Every year, brake issues result in traffic accidents and reduce fleet productivity. The enormous weight of a fleet vehicle places significant strain on the brakes, which makes them more susceptible to failure. Brakes are already under pressure in regular automobiles. Your brakes will remain dependable and trouble-free with regular maintenance.

3. Oil Leaks

Common truck failure codes can stop drivers in their tracks and make them unsure of their safety. There can often be something wrong with the car that could cause problems, but it isn't always obvious to the human eye.

One of these issues is oil leakage. In fleet cars, oil leaks might result in a lack of lubrication, which would increase friction and force parts to rub against one another. It's crucial to be aware of the problem since friction can be so damaging that it can lead to component failure. Routine maintenance will aid in identifying these issues, just like it did with many of these frequent truck breakdowns.

4. Electrical Issues

The electrical system in your car comprises numerous circuits that regulate everything from the music to the headlights. Burned-out bulbs, flawed wiring, blown fuses, and general wear and tear are all causes of problems.

Even while you can use a multimeter and some detective work to find the source of the problem, you should consult an expert if the problem is not as evident as a blown bulb. A skilled mechanic can perform a thorough analysis of the electrical system and offer advice.

5. Overheating

Truck overheating can be caused by several issues. You can have a defective thermometer, a failing radiator cap, or a coolant leak. The actual reason for overheating could be challenging to pinpoint, similar to other problems with fleet vehicles. The root cause may be found with a professional inspection or car diagnostics.

6. Truck Engine Problems

Engine troubles, which cover many issues that could make a fleet vehicle lag on deliveries, may include truck engine overheating. Engine issues and the truck running hot can be caused by blown gaskets, fuel leaks, and a lack of maintenance. When engine issues arise, they can be expensive to fix and add significant delivery delays. A fleet will remain productive if routine maintenance is given more time and money.

7. Broken Clutch

Don't worry if you don't exactly understand what a clutch cable is. As you read this, simply nod to indicate that you understand what is being said. The clutch cable attaches your transmission's pedal to the clutch lever arm. The transmission's ability to smoothly shift between gears is made possible by an inner cable encased in an outer sheath.

As you press and release the clutch pedal, it shifts "out of gear" and enters the new gear. Your clutch cable is wearing if you notice a change in how you need to press the clutch to shift gears. It is prone to snapping because it is made of metal, which results in clutch failures that happen right away.

The inner lubricant could dry out and seize the metal cable in the rubber plastic hose if the outer sheathing is broken. You want a clutch cable replacement to be optional due to a semi-truck breakdown.

8. Engine

Even though today's truck engines are fairly efficient, they are nonetheless susceptible to mechanical failures. Anything from fluid leaks to blown gaskets might cause overheating. Oil oxidation can occasionally cause diesel engines to fail.Fuel injectors, pumps, and gasoline that aren't working properly might potentially lead to engine failure. Truck businesses must be vigilant about testing and maintaining older engine parts because older trucks are particularly prone to engine breakdowns.

9. Exhaust System

As trucking requirements become stronger, fleet managers will need to find ways to reduce their emissions and make sure their exhaust systems match the required levels. Problems with your truck exhaust system could lead to breakdowns and sidelining difficulties alike.

Drivers may be concerned about what is being blown into their vehicles in addition to what trucks are emitting into the environment. A fleet can stay on course by routinely changing cabin air filters and exhaust system components.

10. Alternator or Battery

Turning the key and experiencing nothing happen is painful if you've ever had an alternator or battery go bad or die in the winter. A semi-truck roadside breakdown can persist for hours because of a single red light that might illuminate and no sounds. Most problems with truck batteries and alternators are caused by either the weather or the driving circumstances.

The connectors may have rusted as a result of weather and wear. Are you an Ice Road Truckers member? Are you frequently turning the truck on and off? How long has the battery been in use, and how much electrical voltage is being drawn right now? When your alternator is about to fail, watch for flickering headlights.

11. Transmission Failure

Although a truck's transmission is built to support big weights, cargo demands necessitate routine maintenance. The main reason for transmission failure in semi-trucks is improperly or excessively loaded cargo. Distributing firms or trucking brokers who regulate freight loading limitations are frequently to blame. A heavy cargo weight might cause transmission failure even if the truck's transmission passes inspection.

4. Exhaust System

Your exhaust system can be more painful than you realize because each state is enacting more severe regulations for trucking. Due to the requirement to regularly upgrade and repair your diesel particle filters, it could not be a semi-truck breakdown issue but rather a semi-truck sideline issue.

5. Age

Like other vehicles, your semi-truck's age affects how likely a breakdown is to occur. If properly maintained, semi-trucks may usually travel between 750,000 and 1,000,000 kilometers. If a truck travels 45,000 miles a year, then this equates to nearly 15 years of driving.

You are more prone to have unplanned failures with an older truck, but there are a few things to watch out for, such as:

• A significant drop in fuel efficiency
• Water and oil leaks
• Having trouble picking up pace

Compared to a new truck, an older truck may require more pre-travel maintenance, particularly if you are still getting familiar with the maintenance history.

6. Truck Air Brake System

Compared to hydraulic brake systems seen on cars and light trucks, air brakes behave differently. Based on manufacturer design and application-specific options, all air brake systems vary to some extent.

Compared to conventional brake systems, air brakes have some advantages. More friction can be produced by them, increasing stopping power. They are also designed to endure considerably longer distances, which makes them perfect for heavy-duty vehicles like trucks and buses.

Because air brakes don't rely on friction between the braking rotor and the brake pads to stop the car, they are more dependable than conventional brakes. As a result, they are less likely to have brake fade, a condition where the brakes gradually lose their stopping ability.

7. Windshield Wiper Malfunction

Heavy downpours already increase the likelihood of collision — and defective windshield wipers further exacerbate the problem. Windshield wiper malfunction has been shown to be the cause of rear-end collisions as well as override crashes.

Diagnosing a Truck Breakdown

Even if you are unaware of the exact issue, you can list the symptoms. Here is your approach to deconstructing the problems. Imagine for a moment that you are a fully qualified mechanic or technician for semi-truck repairs and that you have been asked to report on the problems with semi-truck breakdowns. How do you behave?

1. Make a list of any observations you have outside. Are any components missing? Holes? Dents? Anything that shouldn't be pouring onto the ground here?
2. Start the rig up? How does it sound, then? What is the feel of the engine? Seriously. Hours of the day are spent on this truck. You should be at one with the truck's sounds, scents, and touch. You might notice that something is wrong based on the vibrations.
3. Run a system analysis. You may, however, identify various other mechanical, physical, or electrical concerns by simply exploring the truck, kicking its tires, and manipulating a few switches.
4. The truck shifts how? Are the gears adequately engaging? More significant issues might only be apparent when driving. Only when the problems are entirely safe and under control should it be appropriate to mimic such settings.

After listing the symptoms, you can determine the potential issues. The problem can lead you to the solution, and symptoms might point to the problem.

When it comes to fleet truck maintenance, there is a lot to keep track of. Whether you're a fleet manager or a diesel mechanic, you deserve a little assistance in identifying the problem's root cause. To lessen their chance of an unplanned breakdown, truckers should watch for all of these factors. Even though breakdowns are always a possibility, there are precautions that every trucker can take to keep their vehicle in top working order.
