Why Does My Car Sound Like a Motorcycle?

People often complain that their car produces a loud noise that resembles a motorcycle. It makes the driver worry and annoying while driving on busy roads.

Why Does My Car Sound Like a Motorcycle? Your car can sound like a motorcycle due to the damaged engine piston, broken valves, and faulty engine bearing. The problem also comes from leakage in the exhaust system, faulty muffler, and defective resonator. You can also hear this noise due to loose wheels, poorly inflated tires, misfiring of the engine, wear and tear of drivetrain components, and driving belts. The damaged engine walls, poorly arranged cargo space, damaged mounting belts, and dirty filters also cause this issue.

You should not ignore this noise from your car because it can increase the risk of damage to other components. Instead, take your vehicle to the dealerships or service centers as soon as possible to identify the exact problem.

Damaged engine parts

The significant parts of the engine are pistons and bearings that play their role in the ignition. The piston is a cylindrical structure made up of metal material.

It is covered by the piston ring to make it air-tight and protect from leakage. It is present in the cylinders to expand gas through connecting roads.

Sometimes these pistons become damaged and produce uneven noise. For example, you can hear the sound due to the damaged piston ring.

The issue also comes due to the loose tension of the ring. The hitting of the piston with the cylinder valve causes this issue.

The use of low-quality fuel can also lead to the cracking of pistons. You can fix this issue by adding motor oil to every cylinder for its functioning.

The bearings are the essential part of the engine components to reduce friction between several metal parts. However, contamination and oil leakage produce wear and tear in these structures.

The damaged bearings increase friction between crankshaft parts and connecting roads. The metal-to-metal contact while driving produces noise similar to a motorcycle.

You can fix it by changing the damaged bearings to new ones.

Damaged exhaust system

The exhaust system of the cars has several components that function together to reduce the exhaust noise while driving.

Its primary function is to remove harmful gasses from the engine or combustion chamber and release it into the outside environment.

The exhaust pipe has three significant components: resonator, muffler, and header pipe. The damage to any of these components produces uneven sound.

You can hear this while accelerating your vehicle. A muffler is present at the system’s bottom end and helps reduce the engine’s noise.

The engines with damaged mufflers sound like a motorcycle, which annoys other people on the road.

The cooling of the exhaust system causes a buildup of moisture at the muffler surface, making it rust.

The function of the resonator is complementary to the muffler. It does not reduce noise like a muffler, but it helps to reduce the frequency.

In addition, it also reduces the hums and buzzing sounds from the engine.

Exposure to corrosion and driving on bumpy roads cause wear and tear in internal components of resonators and make them out of function.

You can fix it by replacing the corroded or damaged muffler and resonator with a new one.

Wear and tear in the drivetrain

The drivetrain includes the essential components that help transform power from the engine to the wheels for the vehicle’s movement.

It includes a transmission system, drive shaft, drive axle, and tires. 

The issue comes from low transmission fluid, increasing friction between transmission parts, and producing uneven sounds and noises like motorcycles.

In addition, the vibration with loud sounds is the major problem due to damaged U-joints. The wear and tear of solenoid packs also increase friction between various parts and cause a problem.

It is better to check the transmission fluid levels in your vehicle to keep its parts lubricated.

Misfiring in engine

Misfiring in an engine occurs when one or more engine cylinders cannot ignite appropriately to supply power.

The misfiring issue comes from poor installation and wear and tear in spark plugs and their components. Moreover, the problem also comes due to vacuum leakage in the cylinders.

The damaged wiring of spark plugs also makes them faulty and causes this issue. In addition, the low level of oil also causes the cylinders to misfire.

The problem with oil pressure also causes this issue, and cylinders cannot ignite appropriately. The issue also comes due to damaged head gaskets.

You can resolve it by inspecting the spark plug and its wires. Then, replace the damaged cables and worn-out spark plugs for ignition in all cylinders.

Damaged engine valves

The engine valves allow gas entry into the combustion chamber and cylinders for ignition purposes. 

The overheating in this compartment produces cracks in valves which can disturb its functioning. In addition, the problem also comes due to hitting their surface with pistons.

The continuous contact of valves with pistons occurs due to faulty belts and chains. The damaged valves are not repairable, and you have to replace them with a new one for their proper usage.

Problems with driving belt

The driving belt or serpentine belt is beneficial for connecting the alternators, AC, and power steering wheel with the crankshaft.

The exposure to heat due to long-term use causes these belts to break, and eventually, you can hear the uneven sounds from your car while driving.

Moreover, these also become faulty after getting old. You can also face the problem due to a defective belt tensioner.

The too loose or tight connections also cause their breakage. The defective bearing of the pulley and its misalignment also produce noise from drive belts.

You can fix the problem by parking your vehicle at a safe place and waiting for a few minutes to cool down the belts.

Trace the belt’s route to know the exact reason for breakage or malfunctioning. Then, replace the damaged parts to fix this issue.

Damaged air filters

The two types of air filters are present in your car: engine and cabin air filters. This help filters the air and increases the performance of the engine.

The clogged air filters cause inadequate entry of air into the combustion chamber.

The filters also become bad due to the accumulation of contaminants present in the air. You can fix it by cleaning the air filters.

Remove the dust and dirt residues by washing them with pressure water.

Low tire pressure

The low tire pressure produces noise and uneven sounds while driving at high speed and on highways.

The issue comes because a rubber sidewall is not present on the sides of the wheels.

The tire pressure becomes low due to the poor inflation of wheels. In addition, the contact with road hurdles and other objects also causes a loss of wheel pressure.

You must check the pressure on all wheels before driving your car.

Poorly arranged cargo in the trunk

Sometimes people do not arrange their cargo in the truck appropriately. For example, hitting poorly positioned bags and other things with the side walls of the trunk produces noise.

In addition, you can also hear this while driving on bumpy roads. The problem also comes when you place different things in the dashboard.

Driving at high speed and on uneven rads causes these things to hit the sides of dashboards.

You have to properly arrange your luggage and bags in the cargo area so they cannot hit one another and cause a distraction while driving.

Loose wheels

The unbalanced tread surface depth and loose wheel bearing cause the problem. In addition, the poor installation and inappropriate tightening cause the loose wheels.

The issue also comes due to damaged bolts of the wheels and its pavements. The bolts get damaged due to overheating, tightening, and excessive usage.

The damaged and corroded lug nuts also lead to loose wheels, and you can hear noise while driving on highways.

The unfastened tires also increase the risk of accidents and affect the vehicle’s performance. You have to fasten the nuts before going on road trips.

Leakage in the exhaust system

The exhaust system leakage occurs when harmful gasses start to release into the exhaust system before reaching the tail pipe.

The leakage not only produces sound but also decreases the performance. The leakage depends upon the driving conditions and roads.

Overheating occurs when you turn on and off the vehicles frequently. The overheating in the engine damages the gaskets and produces leakage in the exhaust system.

The exhaust leaking is also bad for people sitting inside the cars. The damaged components due to corrosion also cause this problem.

You should avoid driving your car with exhaust leaks because it can affect fuel economy. Instead, wrap the holes and damaged parts of the system using an exhaust pipe to decrease the leakage of harmful gasses.

Loose engine mounting belts 

The mounting belts are in the engine to keep them at their specific place. The engine cannot stay in its place due to damaged mounts.

The hitting of the engine with other parts and the sides produces vibration and noise while driving. In addition, the mounting belts become faulty while driving on poor roads.

In addition, the issue also occurs due to overheating in the engine compartment. You must install the new mounts to keep the engine in its place.
