Volvo is one of the most reliable, safest, and most comfortable heavy-duty vehicles. Countless drivers choose Volvo semi-trailer trucks for their reliable performance and fuel efficiency. Although Volvo is reliable and popular, every heavy-duty truck is prone to problems. Let's explore the five most common Volvo truck problems.
Braking is critical for any vehicle, but the stakes are higher for heavy trucks and semis. If left unchecked, brake-related issues can lead to expensive repairs or, worse, safety incidents. Semi trucks' disc and drum brakes are subject to tremendous pressure, heat, and friction. This operating environment accelerates wear, and without proper care and maintenance, the brakes can quickly wear out. Volvo Truck Brake Repairs May Include:
- Minor Leaks,
- External Corrosion and Wear, and
- Internal Water Contamination.
Volvo Truck Electrical Failure Repairs
Modern semi trucks feature innovative, state-of-the-art circuitry and components, such as alternators, batteries, and starter motors. If one or more of these components fail, your semi truck will be unable to continue driving. Fortunately, there are many warning signs and indicators that your semi truck may be showing that electrical problems are imminent, such as:
Dimming or lowering lights
- Lift flickering
- Dead battery
- Strange plastic smell
- Unusual burning smell
- Clattering noise when the engine starts
Weird or Rough Idle Issues
Allowing your semi truck to idle allows it to continue moving even when stationary. Many drivers use the idle feature to listen to their truck and make sure it is in top condition. If you notice a rough idle, it could indicate a number of potential issues with your engine. A rough idle may be accompanied by a jolt, vibration, odor, or strange noises. Other common indicators of a rough idle include:
Revolutions Per Minute (RPM) Issues: Most trucks have an average RPM of 600 to 1000. But if you notice spikes in RPM, you should perform a truck diagnostic.
Truck Vibrations at Idle: While vibrations at idle are a common problem, you should understand the causes to ensure safe driving and optimal performance. Common causes include bad spark plugs, dirty fuel intake systems, broken hoses, dirty fuel pumps, and worn or loose belts.
Volvo Truck High Idle Issues: If your truck is idling at a high speed, it can cause wasted fuel and extra wear on the engine. This can be caused by a faulty computer system, a bad fuse, or a leak.
Volvo Truck Turbocharger Problem Repair
Another common Volvo truck repair problem involves the turbocharger. Since the turbocharger is a sensitive and delicate mechanical component in your Volvo vehicle, diagnosing the problem quickly can help ensure safe driving and extend the life of your truck. The most common issues associated with Volvo turbocharger problems include:
- Charging tube problems
- Intake support component problems
- Bearing and seal problems
- Another exhaust support component problem
How do you know if your Volvo truck needs turbocharger repair? Here are a few signs that may indicate:
- Louder engine noise
- More exhaust coming out of the exhaust
- Loss in fuel economy
- Loss in power
Volvo Truck Coolant Problem Repair
Your Volvo's cooling system is responsible for keeping the internal operating temperature safe. However, over time, coolant can degrade and require repair. It's best to be proactive with your Volvo truck repair to prevent more expensive damage. Common coolant-related Volvo truck repair issues include:
- Water pumps leaking coolant, holes in radiators, cracked hoses, and other conditions that cause a reduction in the amount of coolant.
- Clogged radiators and coolant system malfunctions cause coolant temperatures to get too high.
- A bad head gasket can cause engine failure to start, overheating, and oil and coolant mixing.
