Common Faults When Buying Used Cars and How To Avoid Them
Are you planning to buy a used car? There are a couple of options you have when buying a car. You can either get it new or used, but there are advantages and disadvantages of both options so you have to be smart about your decision.
First things first: Let’s get one thing straight here – there is nothing wrong with buying a used car! Even if someone were to tell you that it is better to buy new cars instead of used ones because they are more reliable. Well, that may be true but there are always exceptions to the rule and if you do your research properly then buying used cars can save you quite a lot of money!
However, to avoid any trouble with it in the future -there are many things to consider when buying a used car. From the cost of the vehicle to the history, there is much to think about. But before you start researching vehicles, it’s important that you understand how not being careful can lead to problems later on with your purchase. In this blog post, we will discuss some common faults when buying used cars so that you can avoid these mistakes and find the right vehicle for your needs!
Most Common Faults When Buying Used Cars
#1. Car suspension components
The most common cause of vehicle headaches is suspension components, such as broken or malfunctioning springs and dampers. Our study indicates that it affects a whopping one in 10 drivers of vehicles over nine years old.
Aside from having it inspected by a professional, the best method to detect possible suspension difficulties is to put the car on a drive on many routes.
Bumps and uneven terrain are also causes. The suspension is probably in need of repair if you experience any of these: You can hear thuds or knocking as the vehicle goes over bumps The handling feels loose and sluggish When the car goes over speed bumps, it tends to bounce around a lot.
#2. The vehicle’s alternator
The alternator is a component in every vehicle’s charging system. Most car drivers are familiar with the term, but few understand exactly what it entails. The alternator is responsible for operating the dash, battery, air conditioning, and other critical functions in the automobile. Because it is an important component, replacing it after purchasing the part and having it serviced may be quite expensive.
The alternator needs to be in good working order if you are going to make long journeys or drive at night. If it isn’t, the battery could run flat within an hour of starting your trip. In a used car, a faulty alternator is something that you should check before buying it.
If the alternator isn’t charging properly, there are usually telltale signs such as:
- Dim headlights after starting the engine
- The battery warning light is on while driving and when not in operation
- A dead car battery
#3. Flat batteries
A flat battery is one of the most common problems that motorists face. It’s not just an annoyance, but it can also be dangerous. Battery problems are quite common as car ages, but detecting them early before having a vehicle that won’t start is rather simple. This is particularly vital during the current winter lockdown when inactivity and chilly weather play major roles in determining your battery’s charge level.
It’s easy to tell when a car’s battery is healthy: simply start the car. If your engine has trouble starting, the starter motor isn’t working as hard as normal, or the inside or outside lights dim significantly while you start it, there may be a battery problem.
To keep the charge in your battery, try to run your automobile for at least 10-15 minutes each week for a minimum of ten hours. Try not to return the engine immediately after stopping or restarting it. This will require even more power and will deplete the battery further.
If your battery is unable to turn the engine over, you’ll need to jump-start it. Find out how to jump-start your car safely in our video. Depending on the age and condition of the battery, you may be able to replace it completely. The battery will be tested during your car’s MOT, but if you don’t want to wait, several garages in the UK provide free battery inspections.
#4. Vehicle Sensors
Sensors are an integral part of your vehicle and should be checked before buying any pre-owned car. Another concern that has arisen among car owners who bought used cars is the short life expectancy of various engine and electrical sensors.
Over the last decade, all auto manufacturers have added a plethora of sensors to their vehicle lines. This increases electrical usage and dependence, necessitating more component replacements on an ongoing basis. Look for indications of failing systems on the dashboard during the inspection, such as indicators that a warning light is illuminated.
Many modern cars come with sensors that are covered by the manufacturer’s warranty. However, if your car is older than three years or has more than 60,000 miles on the clock, these warranties may not be valid. So, before you buy a used car, it’s important to check whether you will need to pay for the sensors in full.
#5. The Car’s Exhaust & emissions
The exhaust and emissions system on a car is one of the most important, but least understood systems. It’s also one of the most expensive to repair. The catalytic converter is a key part of this system, and it can be very costly to replace if it’s not working properly.
Visible smoke from the exhaust pipe of a car that appears to be operating properly might be an indicator of underlying problems. Exhaust/emission concerns might also be found by listening to the engine as it starts up for any strange or excessive noise. Is there a lot of or unusual noise if the engine starts up? This might be an indication of a ‘blowing’ exhaust, which is caused by corrosion causing little holes in the pipe.
When running a used car check, make sure the engine is cold when you begin it. When engines are warm, they run more efficiently and cleanly. If the gauge shows warm after starting it, the seller may have pre-warmed it and be attempting to conceal an issue.
#6. The Car’s Air Conditioning
The air conditioning in a car is often taken for granted, but it’s one of the most important features during the summer months. Faulty air conditioning can make a car unbearable to drive, especially on hot days. Air conditioners, like other components and systems in the automobile, wear out over time and require maintenance to function properly.
If the car you’re considering doesn’t have working air conditioning, this is a red flag and should be avoided. Air conditioners can be very expensive to replace or repair, and this cost should factor into your purchasing decision.
During a vehicle inspection, make certain to turn the air conditioner to its coldest setting. You should anticipate the air from the vents to be extremely chilly, perhaps around 60 degrees Fahrenheit as the coldest choice. Each vent should also be checked. Open them and see whether the airflow is consistent throughout the car’s cabin. If the car’s air conditioner or water pump isn’t working, there is a high possibility that the system needs to be refilled by a mechanic.
How To Avoid These Issues Before Buying Used Cars
When looking to buy a used car, it’s important to be aware of these common faults and how to avoid them. By being informed, you can save yourself time, money, and potential headaches down the road.
In addition to these tips, always have the car inspected by a qualified mechanic before purchasing. They will be able to look for any other potential issues and help you to negotiate a fair price for the car.
Be sure to do your research and check online for details of common problems with any specific model you’re considering buying. Personal recommendations from friends or family members who own a certain vehicle can also be very helpful in finding reliable cars that are worth purchasing.
The Benefit Of Running A Used Car Check
Before you start the process of buying a used car, it’s important to understand the benefits of running a car history check. By doing so, you can get an idea of the vehicle’s history and potential problems that may need to be fixed in the future.
A used car check will reveal important information about the car, such as its registration status, past owners, MOT history, and insurance write-offs. It can also help to identify any potential problems before they become expensive and time-consuming repairs.
If you’re looking for a used car, it’s important to be aware of the most common faults and how to avoid them. By following these simple tips, you can ensure that you make a safe and sensible purchase.
