Why Does My Car Sound Like Lawn Mower? 6 Causes & Fix
There are 6 main reasons why car sounds like a lawn mower and dies:
Exhaust Leak
Phenomena
Exhaust gas leaks are the first cause of the car making strange noises. The reason is that the chemical part is too high a temperature, creating tremendous pressure on the details as they expand and contract.
At that time, the exhaust part will make a sound that sounds like a lawn mower or car sounds like it’s purring. It usually appears when you try to accelerate or start-up. The easiest way to detect it is to check the exhaust system.
Risk
When an exhaust leak occurs, harmful gases are released into the air before being adequately treated. It will cause smoke to rise in the cabin, and the emission test will not be successful.
Exhaust gas discharged without adequate treatment will include many different toxic gases. They will endanger passengers when these gases enter the seat compartment.
How to fix

Then, take your car to the nearest car service center. Specialists will assist you in identifying the trigger. It may be due to metal corrosion. At this point, they will need to weld the exhaust leak location. Sometimes, you will be asked to replace the exhaust pipe with a new one if the gap is too large.
Failed Wheel Bearing
Phenomena
Wheel bearings usually appear on the top of metal pipes, and it helps to reduce friction significantly during movement.
Therefore, this part is often straightforward to rust after use. Currently, the car sounds like a helicopter or a lawnmower. This sign indicates that the wheel bearing part has failed and needs repair.
Danger
Due to the lateral movement, the wheel bearing is very susceptible to failure and produces annoying noise.
It will make a move a lot more complicated. Moreover, it is hazardous for you to continue driving with damaged wheel bearings. Stop the vehicle as soon as you notice the problem.
How to fix
Even if you hear the mower while driving, you must check each wheel for all faulty bearings. To do this, raise each tire slowly and turn the wheel; the creaking sound will help you identify the problem.
Blown Head Gasket
Phenomena
The head gasket is one of the essential parts of the engine system because it prevents engine oil and coolant from leaking into the environment.
Danger
When a damaged head pad makes a lawn mower sound, it harms your hearing. Moreover, this will release many dangerous gases into the vehicle’s interior. It not only affects passengers but also reduces the speed of the car significantly. At this moment, brake pedal squeaking may also appear.
How to fix
When this happens, you need to seek the help of a mechanic. Please make sure that the new gasket will fit your car. One of the most effective solutions to get rid of head gasket explosion is to keep the coolant level at the proper level. Combine with the correct mixture according to the manufacturer’s recommendations.
Worn Out Tires
Phenomena
Worn tires are the following reason your car sounds like a lawn mower. In addition, under-inflated tires will also make the same noise. Pull over to the side of the road and have your tires checked as soon as you notice this problem.
Danger
When the tire erodes, it will cause the grip to be significantly reduced. Excessive wear can cause a tire blowout to occur. You will realize this when you hear the squeaking of the brake pedal. Even in dry weather, you shouldn’t drive with under-inflated tires. They can cause the vehicle to skid instantly, endangering you and the cars around.
How to fix
To prevent a flat tire from happening, you should check the tire pressure once a month. Also, check it before traveling a long distance or carrying heavy objects.
When a low tire pressure problem occurs, stay calm and park your car on the side of the road. Then, if the tire leak is large, contact the rescue team for assistance.
Engine Misfire
Phenomena
Engine failure can come from many causes, such as clogged spark plugs, faulty oxygen sensors, or clogged fuel injectors. Moreover, when the fuel has not burned out but is still ignited by the rear cylinder spark, it will sound like a lawn mower.
Danger
Driving with a poorly functioning cylinder system will put you in much danger. It requires you to stop the car immediately. Deliberately moving can lead to disaster.
How to fix
You need to check the ignition error by listening to the sound coming from the car. If you hear strange sounds, it could be because the ignition engine is not working correctly. Instead of trying to repair it yourself, you should seek the help of a technician in this case.
Aged Differential Fluid
One of the factors that can cause your car to sound like a lawn mower is an aging differential fluid. This fluid will reduce the friction of the gearbox. At this time, the differential fluid will damage the gears, endangering the entire engine system.
Danger
Cars will be severely damaged if you leave the old differential oil in. It will not be able to reduce the friction of the gear, causing overheating and causing this part to fail. In addition, the kits will also be challenging to bring the car to a complete stop. You will need help to control the vehicle.
Fix
If the gears make noise, you need to contact a mechanic as soon as possible. Differential lubricants can damage and prevent you from traveling long distances. Therefore, to avoid differential oil problems, you should change the oil every 30,000 to 50,000 miles.
