While cars boast high reliability within the auto industry, they aren’t entirely free of issues. This comprehensive guide aims to highlight some common car problems that owners or potential buyers should be aware of.

Before we delve into the specifics, let’s establish that these issues do not undermine the overall quality and performance of cars. Every vehicle make and model has its own set of quirks and flaws. The primary objective here is to inform and equip you better when dealing with these problems.

1. Engine Oil Leaks

Car isn’t immune to engine oil leaks. This issue seems to be particularly prevalent in some car models such as the Frontier, Rogue, Versa, and Altima.

In some cases, the issue was traced back to sub-standard bolting used during production.

Despite this, Cars seems to have improved in recent years, with fewer oil leak issues reported.

Causes of Oil Leaks

Overlooking oil leaks can result in sky-high maintenance costs. Most oil leaks originate from degraded engine gaskets or leaky oil pans. Other times, bad connections, fittings, or a broken filler cap might be the culprits.

Depending on the severity, fixing an oil leak in a car could cost anywhere from $100 to $2,000.

2. Rust Issues

Car has faced significant criticism for rust-related problems, especially with the Navara truck.

Severe rust can weaken the link between the cabin and cargo area, leading to the infamous snapping that can leave the connection completely severed.

While snapping incidents aren’t common, rust issues are. It’s not just the Navara; other models like the Altima and Xterra also face similar issues. Regular inspection of your car’s underbody to ensure it’s rust-free is recommended.

Causes of Rust

Several factors contribute to rusting in cars. Continuous exposure to rain, snow, or sun rays can increase the likelihood of metallic parts rusting. Neglect and lack of proper care can also exacerbate rusting. With time, the paintwork and protective coatings on your vehicle may degrade and wear off, making your car more prone to rust.

3. Sunroof Issues

Certain Car models like the Maxima, Pathfinder, Rogue, Murano, Infiniti JX35, and QX60 have reported issues with sunroofs shattering and causing injuries.

The aftermath of exploding sunroofs can result in injuries to passengers and even cause drivers to become disoriented while driving, leading to potentially fatal accidents.

Causes of Sunroof Issues

Extreme weather and debris contact are often blamed for shattering sunroofs. However, most drivers who have experienced sunroof explosions believe it occurs randomly due to substandard engineering. Laminated glass is suggested as a safer alternative to tempered ones for sunroofs, as it won’t shatter suddenly even when compromised.

4. Fuel Gauge Problems

Fuel gauge issues in cars often stem from a malfunctioning fuel-sending unit.

When the sending unit fails, it displays incorrect fuel readings, and the fuel gauge can get stuck in either ‘full’ or ‘empty’.

Car has also recalled several vehicles due to faulty fuel gauges.

5. Transmission Issues

Car CVT transmission problems peaked between 2012 and 2015, especially evident in the Sentra and Altima models. Issues involved poor CVT response, vibration, rough running, stuck gear shift, and loss of acceleration. In severe cases, total transmission failure occurred. For more clarification, just ask an expert at Service My Car.

Final Thoughts

Knowing about these common car problems doesn’t mean you should steer clear of the brand. Instead, this knowledge equips you to make informed decisions when buying or maintaining your vehicle.

Fuel always needs to enter the combustion cylinder for compression and then ignition. Over the years, carburettors and fuel injectors have dominated the fuel supply inside the engine. Though fuel injectors are paving the way for the future, carburettors are already out of the race.

In the case of four wheels, especially cars, fuel injection has been trending towards absolute dominance. However, carburettors have not gone completely out of sight, which makes for an interesting automobile discussion.

But first, let's look at how a carburettor works and how it supplies fuel to the engine.

How does a carburettor regulate fuel supply?

A carburettor’s basic structure is a cylinder that has an inlet at the top. This inlet allows air to enter the carburettor after cleaning through the air filter. There is a mechanism (venturi, tapers) that restricts air flow and increases air velocity.

A jet releases fuel at the vent, creating an air-fuel mixture that enters the combustion chamber.

At the outlet of the carburettor, a valve (the throttle valve) controls the air flow, its position dictates the air suction into the carburettors where the throttle valve is controlled by the accelerator. When you press the accelerator, the throttle valve opens and increases the airflow. As more fuel flows into the carburettor, the vehicle can burn more fuel.

When you decelerate the pedal and the engine slows down, the supply of air to the fuel mixtures decreases.

How does the fuel injection system manage fuel supply?

A fuel injection system usually has a nozzle inserted into the combustion cylinders. Fuel goes through the pressure pump where it gets atomized, and later it mixes with the air before getting sprayed into a combustion cylinder.

However, an air sensor regulates air intake. Similarly, fuel delivery happens based on the instructions of a fuel sensor. Though there would be other sensors to sense the engine workload, temperature, and throttle position, all these sensors send data to the ECU, where the delivery of fuel is decided by making a number of calculations.

Why do fuel injection systems take over the carburettors

Almost all modern vehicles, particularly those manufactured since the turn of this century, are now equipped with a fuel injection system. What has forced this subtle change? Of course! Why should automobiles fall behind as the world adapts to computer-based technologies?

The carburettors are more of a manual system of fuel injection, there is no intervention from the ECU or any sensors. The amount of air required to ignite the fuel mixture inside the combustion chamber is determined by the throttle position.

On the other hand, the fuel injection system depends on ECU (Electronic Control Unit) to control the majority of the processes in an engine. Electronic controls determine the highly precise delivery of fuel using a number of details from a number of sensors, such as air intake, throttle position, engine speed, etc. All details are processed at the ECU, where it decides how much fuel to supply. So the system takes the decision on fuel delivery and makes fuel injection an efficient system to provide as per the requirements. The fuel injection’s efficiency is so great that it allows a vehicle to start quite easily in the hardest of conditions, like on extremely cold days.

Nowadays, carburettor-equipped vehicles are mostly two-wheelers. Here, the point is that when you need to start a two wheeler, a choke comes into action. Once you pull the choke, the vehicle can only start. Then, you have to warm up the vehicle properly to run it further.

Carburettors require the same effort to start a car on four wheels on cold days. You have to use the choke and warm the engine before driving further. But the fuel injection system discards such requirements.

Besides, carburettors are not the best choice when there is discussion about fuel efficiency because precise delivery of fuel does not let it get wasted. However, there are a number of vehicles apart from the passenger car that prefer carburettors, especially its much improved version known as direct injection.

Besides, there are some geographic areas where there is a demand for carburettor-based vehicles. And somehow they are receiving the supply of these vehicles. Usually, vehicles are bought from the original automakers before making changes such as eradicating the computer controls and using more mechanical devices such as carburettors. The primary reason behind such modifications is to cut the final cost of vehicles.

Is it difficult to maintain fuel injection when compared to carburettors?

The carburettor is more of a mechanical device. Therefore, it requires some hand tools and a willingness to get your hands dirty to repair a carburettor. Though, you cannot do it without a proper technical skill if there is a need of a car engine repair.
