The Top 6 Common Used Car Problems and Their Solutions

Posted Wednesday, Jul 26, 2023

Purchasing a used car is a cost-effective solution to getting your favorite car. However, since old cars have been used for a long time, you will find many issues with them from time to time. Being a car owner, it is necessary to understand the importance of regular car maintenance, used car problems, and their solutions.

Being aware of vehicle problems and taking care of regular maintenance help prolong the life of your car and ensure that you stay safe on the road.

Have a look at the commonly used car problems and their solutions to ensure that your car runs at its best for the years to come.

1. Engine Overheating

Multiple causes can lead to engine overheating in used cars, which can lead to severe damage if left unchecked. Generally, it happens due to a problem with the cooling system of the car, due to which it is not able to escape the car. A faulty radiator, a clogged coolant hose, and a broken water pump can also cause engine overheating. An overheated engine can lead to a fire in extreme cases.

No matter the cause, you need to get it checked immediately to prevent further damage.

Solution: Pull over the car just as the engine starts to overheat, turn off the car, and let it cool down. Check the coolant level, but ensure the engine has cooled down before you do so. Add 1:1 coolant and water. Once stable, take your car to a mechanic to check for leaks and other malfunctions.

2. Brake Problems

Brake pads can become damaged or worn over time with continuous usage. This is why most used cars have brake problems. You can check them by inspecting the brake pads, brake lines, and rotors. Inspect the brake fluid level and check for signs of damage.

Solution: The repair cannot be made unless you find the exact source of the brake problem. Therefore, you should get the brake system inspected by a professional. There might be a need to replace the worn-out parts. Take timely action, as brake maintenance is crucial for safety.

3. Uneven Tire Wear

Tire wear is common, and it is perfectly normal. However, if you notice quick tire wear or uneven tire wear, this indicates a problem. You might also feel a vibration in your steering wheel due to uneven tire wear. Various factors like unbalanced tires, improper alignment, and suspension problems can lead to uneven tire wear.

Solution: Get the wheel alignment checked after purchasing the car. You will need professional help to ensure proper alignment if it is misaligned. Once set, you should check the tire pressure and tread regularly. Also, rotating the tires regularly helps promote even wear across all four tires.

4. Air Conditioning Issues

Air conditioning issues are also quite prevalent in used cars. Most often than not, a refrigerant leak is the cause of nonfunctioning car air conditioning. A faulty compressor, worn-out blower motor, damaged condenser, and malfunctioning thermostat are some other causes of air conditioning issues in a used car. These may lead to strange noises from the AC, foul odors, and strange noise.

Solution: Ineffective cooling might be due to low refrigerant levels. Check that and top it up. Also, consider replacing the cabin air filters regularly to prevent odors and improve air quality. If the AC stops working, you might need to see a technician to identify the cause and the solution.

5. Suspension and Steering Problems

Suspension and steering problems are also very common in used cars. Worn shock absorbers lead to uncomfortable rides, while faulty struts can cause rough rides and excessive bouncing. Problems with the steering system can cause steering wheel vibrations. There can also be leaks in the power steering system, which makes it difficult to move the steering. Damaged suspension components produce rattling and clunking noises when you turn the car or ride over bumps.

Solution: Shock absorbers, struts, and other such components need to be regularly checked and replaced to maintain car handling and stability. You should take your car to a professional for proper inspection and check the car's alignment. This is done to ensure proper adjustments. You might need to lubricate the steering and suspension if you hear unusual noises in the steering wheel.

6. Exhaust Smoke

Another very common used car problem is exhaust smoke, which is typically an indication of an underlying issue. If you notice black smoke, it suggests a rich fuel mixture that can lead to incomplete combustion. White smoke may suggest some cooling system problems due to coolant entering the combustion chamber. Blue smoke is also commonly observed, which indicates burning oil. It occurs due to worn valve seals or piston rings.

Solution: Ensuring proper maintenance can prevent black smoke from the exhaust. You should check the filter and fuel injectors for any issues. For the blue smoke, it is necessary to use high-quality oil. In contrast, a white smoke issue can be resolved by taking your car to a professional for inspection and repair.
