Common Hidden Issues to Watch Out for When Buying a Used Car
Buying a used car can be an exciting yet nerve-wracking experience. Often, vendors may present the vehicle in the best possible light, which is where a thorough inspection becomes crucial. This article aims to identify some of the most common hidden issues you should be aware of when purchasing a used car. Whether you’re a car aficionado or just an enthusiast, understanding these issues can save you from financial and safety pitfalls.
1. Brake Fluid Inspection
One of the most critical components to check in a used car is the brake fluid. If you have no prior knowledge about cars, getting the vehicle inspected by a professional is highly recommended. The color of brake fluid is a significant indicator of its condition. Ideally, brake fluid should appear clear, though it can change color slightly depending on the brand. However, if the fluid has turned a dark brown or rusty color, it may be indicative of a severe issue.
Brake fluid affects the integrity of the hydraulic systems in the car. As it decomposes over time, it can turn into a corrosive substance, referred to as "liquid sandpaper." This fluid can damage the brake lines and hoses from the inside, causing wear and tear. It can also erode the brake-caliper castings, master cylinder pistons, and potentially affect the Anti-Lock Braking System (ABS) pump seals. These damages are not always visible during a test drive and can lead to severe safety hazards.
The solution to this issue is a thorough brake fluid flush and refill performed every two to three years. Regular maintenance is crucial to ensure the safety and longevity of your vehicle.
2. Fluid Checking and Visual Inspection
Inspect the oil fill hole; any sludge or discoloration is a red flag. Continuously remove the Oil Fill Cap and check for any residue or discoloration on the back side. Additionally, take the car to an oil change garage and drive it over a pit to check for leaks or any rusted subframes and shackles.
Another crucial check is the steering system. Have two people check the tie rods by having one shake the steering wheel while the other listens for sounds that may indicate a failure. If the tie rods are bad, the car may suddenly lose control and lead to an accident. Tie rods typically need replacement after about 40,000 miles. Similarly, ball joints are a significant safety concern as they can cause a complete loss of control if they fail. They should be inspected and replaced regularly for safety.
3. The Seller’s Morality and Integrity
Sellers often embellish the car's history to make it seem more appealing. For example, a car might be marketed as a one-owner car used by an Episcopalian minister who drove it only to church across the street, or as a new car that just arrived at the lot. These claims are sometimes baseless and intended to deceive buyers.
Truly attentive buyers should be cautious of such claims. A car may have been owned by more than one person, or it might have been driven in different climates, affecting its condition. For instance, a car with a block heater and snow tires might actually be from a colder climate, or it could have been sold as a Texas car despite its winter readiness features.
If a seller mentions that certain problems have been fixed by mechanics who also worked on high-end cars, such as Lamborghinis, be wary. This might indicate that the car has had significant issues, and they might be trying to cover up these problems.
4. Potential Risks of Buying Used
Buying a used car involves significant risks, as certain issues may not be visible during a routine test drive. The car might explode, or it could contain a cup of sawdust in the differential, which could lead to serious performance issues. In some cases, someone might have died in the vehicle, leaving behind traces that could be discovered in hot weather.
Moreover, a used car might have hidden maintenance issues. For example, I bought a 2003 Acura TL for $2,500, and within a year, it required numerous parts to be replaced. The expenses included replacing the battery, drive shafts, struts, ball joints, windshield-washer pump, and more. It also needed various maintenance tasks such as cleaning the ant farm, replacing the EGR valve, spark plugs, and other minor repairs.
These issues are often unnoticeable during a short test drive and can become apparent only after several months of use. Therefore, it's crucial to understand that a thorough inspection is necessary to ensure the safety and longevity of your used car.
By keeping these points in mind, you can make a more informed decision when purchasing a used car, minimizing the risk of hidden issues and major inconveniences down the road.
