Learn about common repair issues in commercial fleet vehicles, including engine, suspension, and transmission problems, and how expert repairs keep your fleet on the road.
Engine Troubles
Engine problems are one of the most common issues in commercial fleet vehicles. These vehicles are used frequently and undergo tough conditions, such as long-distance travelling, carrying heavy loads, and frequently stopping and starting.
Unusual noises, loss of power, rough idling, warning lights, or higher fuel usage are all common signs of engine issues.
In more serious cases, the engine may overheat, fail to start or break down entirely. If these issues are not fixed, they can affect the vehicle's performance and your safety on the road.
The spark plugs, filters, belts, and sensors can wear out faster in fleet vehicles due to their high mileage and daily usage. These vehicles often run for longer periods and in more demanding conditions than standard cars.
Poor maintenance or skipped servicing can lead to further problems like oil sludge build-up, blocked air filters, or coolant leaks - all of which can cause the engine to overheat.
Suspension And Steering Problems
Suspension and steering issues are common problems in commercial fleet vehicles. These systems are essential for safe driving, however, due to their constant usage, these systems often experience more wear and tear over time.
Fleet vehicles often carry heavy loads and travel long distances, which can cause the springs, shock absorbers, struts, and bushings to wear out faster over time. If these components become worn or damaged, the vehicle can feel less steady, bounce more than normal, or make knocking sounds when going over bumps.
Steering problems can also develop in frequently used fleet vehicles. Issues such as stiff or loose steering, vibrations, or pulling to one side can make the vehicle harder to control on the road. These issues can be caused by worn tie rods, ball joints, steering racks, or low-power steering fluid. Poor wheel alignment can also affect the steering performance.
Ignoring suspension or steering issues can make driving uncomfortable and reduce the driver's ability to control the vehicle, especially when braking or turning. For fleet vehicles, this can increase the risk of accidents and breakdowns on the road.
Suspension and steering faults are common in commercial fleets. Addressing these issues quickly through proper maintenance and professional repairs helps protect drivers, reduces downtime, and keeps the fleet running smoothly. Regular servicing ensures that vehicles remain safe, stable, and comfortable for everyday business use.
Transmission System Problems
Transmission problems are among the most common issues in fleet vehicles. One major cause of transmission problems is low or dirty transmission fluid, which is used to help the system run smoothly. Without the right level or quality of fluid, the transmission system can overheat or stop working entirely.
Damaged gears, faulty sensors, or problems with the clutch in manual vehicles can also cause the transmission system to wear out. Driving habits, such as harsh acceleration and heavy towing, can also add strain and lead to early transmission failure.
When a fleet vehicle has a transmission problem, it can affect how the vehicle drives. One of the first signs of transmission issues is difficulty changing gears. The vehicle might slip between gears, struggle to speed up or feel slow to respond.
If this issue is left unchecked, the vehicle may stop moving altogether. For fleet operators, this means delays, missed deliveries, or even roadside breakdowns.
Keeping the transmission system in good condition is crucial to improve the vehicle's fuel efficiency and extend its lifespan. Therefore, fleet managers should always make sure their vehicles are regularly checked and inspected for transmission problems.
Fluid Leaks
Fluid leaks are one of the most common issues in fleet vehicles. These vehicles are often driven long distances every day and used in all types of weather and road conditions.
This heavy use puts extra pressure on engine parts, hoses, and seals, which can lead to leaks. Engine oil, coolant, brake fluid, transmission fluid, and power steering fluid can all leak out of the vehicle and affect its safety on the road.
Transmission fluid keeps the transmission system cool and well-lubricated. If it starts to leak, the transmission can overheat, which puts extra pressure on the engine and may lead to further damage if it's not fixed quickly.
This extra strain can lead to reduced fuel efficiency, poor gear changes, and long-term damage to both the transmission and the engine. In some cases, the engine may overheat or struggle to run properly due to the added pressure.
Transmission leaks can put drivers and others at risk on the road. A sudden loss of fluid can cause the vehicle to break down or become difficult to control, which can lead to missed appointments, delayed deliveries, or roadside emergencies.
Fluid leaks can also damage roads and car parks by leaving slippery patches that are unsafe for other road users.
For fleet managers, it’s vital to deal with fluid leaks straight away. Fixing small leaks quickly can save money in the long run and helps drivers avoid bigger, more expensive repairs. Keeping fleet vehicles in good condition also means they perform better and spend less time off the road.
