2010 Honda Civic Problems And Reviews: Is That Car Reliable?

What type of issues will I likely run into with a 2010 Honda Civic?

The most common 2010 Honda Civic problems are transmission faults, engine vibrations, and cracked engine block problems. It should be noted that the identified problems are what 2010 Honda Civic users have observed and complained about overtime.

Additionally, Honda enthusiasts have also generally reported these cases. What it implies is that they are issues not essentially related to a flaw in design but old age and largely lack proper maintenance.

Here’s the highlight of the problems:

  1. Transmission Problems
  2. Engine Vibrations
  3. Cracked Engine Block Problems

Ever since its introduction into the car market over a decade ago, the 2010 Honda Civic has been incredible overall.

With that being said, I will be explaining in detail the most common problems associated with that vehicle as you read this article in detail.

What Are The Most Common 2010 Honda Civic Issues?

1. Transmission problems

Top of my list of the most common 2010 Honda Civic problems is the transmission issue. Transmission problems are not fundamentally design-related.

Let me burst our bubble: whether in the Honda Civic engine or any other auto engine, transmission issues are largely due to improper maintenance.

As a matter of fact, the 2010 Honda Civic engine can spend more than a decade without developing faults. Whether it is a result of improper maintenance, old age, or production problems, transmission issues have been one of the most common problems associated with this engine for a longer time.

This problem can be a very daunting one to face and at the same time, it can be very expensive to fix. When there’s a transmission issue with this engine, there are certain symptoms the engine will put up.

The transmission consists of various interconnected parts which move continually, rubbing and heating. In addition, it comes with a wide range of functions, including communicating with both internal and external parts of the engine.

Causes Of Transmission Issues

As I’ve noted, the transmission issue with the 2010 Honda Civic doesn’t essentially originate from a flaw in the design.

Generally, there are three important triggers of transmission issues in a car engine:

1. Transmission Leaks

One of the most common transmission problems is transmission leaks. Transmission leaks can have a devastating effect on the internal transmission of your Honda Civic engine. These problems arise from leaking driveshaft seal, axle, or pan gasket. The transmission cooling line can also leak.

All these leak issues can cause a low level of fluid as well as overheating and burnt fluid. Fixing a leaking pan gasket or transmission cooling line may come on the cheap. But you’ll have to spare a few bucks of dollars to replace the converter seal or output shaft seal.

2. Damaged Torque

The car needs a torque converter to provide pressure to the transmission fluid. The pressure is used by the transmission gears to achieve smooth shifting.

However, once the torque converter is damaged as a result of worn needle bearings, the transmission will start to give off strange noises while you’re driving. Specifically, the car will grind or brush sounds when it is in driving gear.

3. Clogged Filter

Another visible reason you may experience transmission issues in your car is a clogged filter. If the filter is clogged, chances are that the transmission fluid becomes dirty.

The consequence is transmission failure and sluggish shifting. The best remedy is to replace the clogged filter with a new one.

4. Low Of Adulterated Transmission Fluid

That low transmission fluid causes problematic transmission is a no-brainer. Once the fluid leaks away or gets contaminated, it causes the smooth gear shifting to become nearly impossible and transmission extremely difficult to attain.

Replacing contaminated fluid or topping fluid levels is expedient. You should repair the leak before pouring fresh fluid.

What To Watch Out For

Now that you are familiar with what transmission problems are all about, I will talk about certain symptoms you should look out for before your engine breaks down due to transmission.

  • Stalling: This problem prevents the car from moving properly. It is an early symptom is that your engine is about to have a transmission problem and may also be due to leaking transmission fluid.
  • Delay In Transmission Shifting: This symptom indicates problematic transmission and it’s often accompanied by a pause before you move the car. This pause may be experienced while driving in a forward motion by shifting into first gear or below the gear.
  • Clucking, Screeching, Or Whistling Sound: These sounds are one of the foremost symptoms that can indicate there is a problem in the Honda Civic engine.
    These sounds will continue even while in motion. Other symptoms include a thick or foul smell of transmission fluid.

What To Do

Replacing your transmission is the best way to prevent further Honda V6 Engine Problems.

Replacing the transmission is, however, an expensive task and may cost between $1,800 to $3,500, including costs of purchasing parts and labor.

My simple advice is to always watch out for the above symptoms to avoid a sudden breakdown of your engine.

2. Engine Vibration

Vibration during the engine’s operation can be a normal process, and however, the vibration must be at an optimal level. The rotation of certain engine components such as crankshafts and other important parts of the engine can produce slight vibration.

This specific problem: engine vibrations and rattling are both major issues and are mostly noticed as the engine begins to age. Rattling and vibrations in engines are caused by engine mounts as wear and tear set in.

Engine vibrations can be a result of a worn-out or damaged spark plug. It can sometimes shake uncontrollably. When your Honda Civic engine spark plugs go bad, it will cause the engine to vibrate as there can be misfiring of the cylinder even while on speed or at rest.

When vibrations go beyond excess, it will lead to the production of rattling sounds and the engine can degenerate if no attention is paid.

Causes Of Engine Vibration

1. Worn-Out Spark Plugs

If your vehicle is running on worn out or dirty spark plugs, one of the earliest symptoms is engine vibration. The engine will start to misfire. It may also not properly fire on each cylinder. You can either fix compression-related issues or replace the spark plugs, or both.

2. Defective Timing Belt

Faulty belt or belt-driven accessories in your car can cause the engine to vibrate and nastily shake when moving or idling.

Specifically, once the fan and other belt-drive parts cannot rotate due to a faulty timing belt, the vehicle will give inconsistent speeds and so ends in vibrations and strange sounds.

Make it a point of duty to regularly inspect all the belts in your vehicle. Check them for ribbing and cracks. Also, check if they’re losing their thickness.

3. Damaged Transmission Mounts

If you notice that your engine violently vibrates or the vehicle shakes uncontrollably when idling or slowing down at a red light, one of the culprits is broken engine mounts.

When your car’s transmission mounts are damaged, the vehicle will shake and stop or reduce after a few minutes. To test this, shift the gear to neutral and observe if there’s a reduction in vibration or shaking.

4. Loose Air Hoses

Loose hoses can cause the engine to vibrate excessively. You’ll need to have the car checked by a professional mechanic to see if the vacuum hose or air hose is disconnected or loose from their end.

If it’s discovered that the hoses are loose, you should tighten them; otherwise, then it’s time to replace them.

What To Watch Out For

Engines vibrations are inevitable as wear and tear sets in. Having understood what vibrations are, let us take a look at the symptoms to watch out for before concluding your engine vibrates.

  • Engine Misfire: This may be due to your engine not supplying the essential ingredients to other parts of the engine at the right time or quantity such as fuel mixture, spark, or compression.
    If any of these ingredients are not channeled to the right places, you will experience a misfire of the engine as a result of incomplete combustion. It is a good sign that accompanies engine vibration. Failed spark plugs may also cause the engine to misfire.
  • Engine Stalls And Shuts Down: Vibrations in the engine can be a result of broken hoses causing the engine to stall or shut down.
    Disconnected or worn-out hoses will not supply the required amount of fuel to vital parts which shut the engine down indefinitely. Broken hoses may also cause the engine to lose power.

What To Do

Failed spark plugs and ignition coils in Honda Civic engines do not happen instantly but start to wear down over time. When the plugs fail, this will result in the engine vibrating continuously, stutter, and stumble when the engine is in operation.

Fortunately, these two components do not easily break down and when they do, you won’t be spending too much money to fix or repair them. Replacing these parts can help to solve vibrations, especially if you have not replaced them in a long time.

Engine Mounts in 2010 Honda Civic bears the entire weight of the engine and due to this, it is not bad they start wearing out after some time.

Mounts in engines are rubber materials that absorb impacts and vibrations. Wear and tear begin to set in with time and replacement may require you to spend about $300 to $500.

3. Cracked Engine Block Problems

Unfortunately, users of this engine are mostly faced with engine block problems, making it one of the most common Honda V6 Engine problems. Engine block problems are mechanical issues that can result in safety issues while the engine operates.

Ultimately, since the circulation system responsible for cooling the engine is fragile, a cracked engine block can result in coolant leakage from the area needed in the engine components. This effect will cause the engine to overheat, coupled with low engine compression.

Cracks in the Honda Civic engine do not commonly happen and when it happens, it can be due to some reasons.

It is not advisable to drive cars with a cracked blocked engine as it can lead to total shut down of the engine. When this happens, a new engine will be needed to get the car up and running again.

Summarily, certain reasons may be responsible for the cracked engine block, the symptoms I notice in my engine’s performance will indicate the action to take. However, before you can conclude your engine is not at its best due to a cracked engine block, you will notice certain signs.

Causes Of A Cracked Engine Block

  • Overheating: When the temperature gauge rises above normal, the engine block will crack. An overheated engine itself is caused by a wide range of things, including a broken water pump, cooling system leaks, radiator issues, thermostat failure, low or no coolant, and more. For instance, if your car engine gets too hot, it cracks the block due to thermal stress. Again, if the amount of water in the cooling system is far more than the antifreeze, the block can crack in freezing temperatures.
    This is because, as the water expands and freezes, more cracks will be created in the block.
  • Casting Flaws: The 2010 Honda Civic engines are reported to have been built with casting and design flaws. This causes the block to crack. To cover the flaw, Honda models have an extended warranty.

What To Watch Out For

Cracked engine block issues are accompanied by some symptoms and it is important I let you know some of the symptoms to watch out for.

  • Overheating: Honda Civic engine will overheat if there is a cracked engine block and if it’s too severe, it will lead to the antifreeze leaking from the block.
    The absence of antifreeze will cause the engine to overheat, which is often accompanied by a whitish smoke oozing from under the hood and a hit gauge.
  • Poor Engine Performance: One of the symptoms to watch out for if your Honda Civic engine has cracked engine block problems is its performance.
    The engine will lack power and will not perform at its best state. You will notice low compression which leads to combustion pressure lock, coupled with likely rough idle.
  • Engine Smoke: When you notice a blackish-grey or blue smoke from the hood, it is a symptom that there is a cracked engine block problem.
    Smoke is produced as a result of the crack allowing exhaust fumes to pass at the crack instead of passing through the exhaust system.
  • Antifreeze And Oil Mixture: Another sign of cracked engine block problem is antifreeze and oil mixing. It cannot be overemphasized that you should check the color of your fluids when you’re carrying out coolant flush or oil change.
    This should also be done when you’re conducting scheduled maintenance of your car. If the oil and antifreeze have mixed, you’ll see a milky white substance. When this happens, you can rest assured that there’s a crack in the engine block, usually between the liquid flow passages.

What To Do

I recommend the entire replacement of a cracked engine block. However, the replacement comes with a huge sum as you will need to budget around $1,500 to $2,000.

Older models with this specific engine problem may not be advisable to repair as they may be prone to the same issue not sooner after repair.
