1. A battery failure
   It hasn't been given enough time to cool off.
2. The car is low on refrigerant.
   It isn't warm enough outside to need A/C.

While there are different reasons why your car might not be blowing cold air through the A/C unit, the most common is a lack of refrigerant. Refrigerant is in charge of cooling your car. A leak can often cause the lack of a suitable amount of refrigerant.

1. The brakes are just cold.
   Brake pads are loose.
2. Brake pads have dust in them.
   Brake pads are worn out.

While cold can do a lot of negative things to your car, it should not make your breaks noisy. Common reasons for noisy brakes include pads that are worn out, have dust in them or are loose.

1. The battery is dead.
   Something is wrong with your alternator.
2. You haven't driven long enough to start the charge.
   A car battery isn't supposed to charge while driving.

When you are driving your car, the alternator is responsible for generating enough power to keep the battery juiced up. If the battery isn't charging or is dying while driving, the alternator is the first place you should look.

1. Using the wrong type of gas for the car
   It indicates you are low on gas.
2. Coolant entering the combustion chamber
   Some cars just have white exhaust smoke.

If you notice that your car is emitting a white exhaust smoke, it is often due to coolant (or oil) leaking into the combustion chamber. This is often due to a gasket issue.

1. 25,000 miles
   500 miles
2. Every two years
   5,000 miles

While this will vary depending on the car, it is generally recommended that you get your oil changed every 5,000 miles. Your owner's manual should have more information if you want more specific advice for your make and model.

1. Misalignment
   Suspension issues
2. Wheels are unbalanced.
   Any of the above could lead to a shaky or vibrating steering wheel.

Driving with a shaking steering wheel, or dealing with one when you're idle, can be a scary feeling. Many different reasons could be causing the steering wheel to vibrate, including the ones we mentioned here.

1. It's been more than six years.
   Shallow or worn tread
2. When they are deeply punctured by a nail
   All of the above are reasons to get tires replaced.

Having suitable tires on your car is one of the best ways to stay safe while driving. Thankfully, there are many different signs that will alert you if it is time to replace any or all of your tires.

1. Oxygen sensor failure
   Your windshield wiper fluid is low.
2. A loose gas cap
   Spark plug issues

Having a check engine light come on is generally a sense of worry for most people. There are many different reasons why it can occur, but having a low windshield wiper fluid won't trigger the indicator.

1. Moving the different components of the braking system
   Prevents ice from forming on breaks.
2. Keeps brakes cool to the touch.
   Only lubricates the brakes and nothing else.

When you press the brakes, brake fluid is sent through the brake lines to each caliper. This then signals your brake pads, which allows your car to stop. So without brake fluid, you would not be able to stop your vehicle effectively.

1. A piston moves out of place.
   The metal connecting the piston to the crankshaft breaks.
2. Engine cylinders become locked up.
   When you push the gas pedal too quick

Throwing a rod can be incredibly harmful to your vehicle's engine. It is caused when the metal rod that attaches the piston to the crankshaft breaks, and can instantly ruin an engine.

1. It is an oil leak that has been left too long.
   A coolant leak
2. Rust mixing with other fluids
   It is a transmission fluid leak.

Despite how much it might look like it, don't worry, that red fluid under your car isn't blood. Transmission fluid is red, and it was designed this way so it could be easily identified. If you see this fluid, there is likely a leak somewhere in your transmission.

1. A dead battery
   It's too cold outside.
2. Not enough gas in the car
   Your coolant levels are off.

We have all had the harrowing experience of trying to start our car only to be met with a click or ring every time we try to turn the key over. While loose connections and starter issues can cause this, the most common reason is a dead battery.

1. Trustworthiness and honesty
   Experience in the field
2. A mechanic who has a nice car themselves
   A good reputation

The type of car a mechanic has is no indication of how high quality they are. Instead, you should look for a trustworthy and honest mechanic, with a good reputation and a lot of experience.

1. Regulating the temperature of the vehicle
   Provides the spark that is responsible for starting a vehicle.
2. Making sure the car has enough gas
   Helping with gear shifting

Spark plugs are perhaps one of the most important part of the car's motor. It provides the spark that helps ignite the mixture of air and fuel that ignites the car and keeps it going.

1. Issues with the transmission
   Faulty air filter
2. Burned oil in the engine
   A lack of brake fluid in the car

Struggling to change gears in a car can make it very difficult to drive safely and effectively. Your transmission is likely to blame for this struggle and it could be from an actual failure or just a hose that came loose.

1. The steering wheel is too tight.
   Your tires aren't aligned.
2. Your car's belt is likely compromised in some way.
   Your windows aren't rolled up all the way.

When you pop the hood and check the belt, it will be easy to see it's damaged, but usually, you can hear it squeak while driving. It will be impossible to ignore as it will be quite annoying and happen frequently.

1. Something serious is wrong and requires immediate attention.
   You need more oil.
2. It is just a sensor malfunction, don't worry.
   Treat it like a regular check engine light.

While a normal check engine light usually isn't a super serious concern immediately, a flashing CEL definitely is. It means your engine is misfiring in some way, and serious damage could be done to the car if you don't get it checked soon.

1. Replace it or have it replaced with a new bulb.
   Turn off the car and back on again.
2. Get a new battery.
   Let the car run for five minutes and it should turn back on.

Just like any light in your home, a headlight bulb can be replaced with another one if it burns out. They cost only a few dollars and changing them out yourself is generally quite simple.

1. An oil leak
   Coolant leak
2. Brake fluid leak
   Gas leak

In a car, there can be many different fluids that can leak. If you notice a brown leak, it is most likely an oil leak. Oil leaks can occur for various reasons including loose seals and connections, wear-and-tear or physical damage to the oil pan.

1. 10-15 PSI
   5-10 PSI
2. 30-35 PSI
   75-90 PSI

Usually, it is recommended that your tire pressure remains between 30-35 PSI. However, each vehicle will have a max PSI listed on the sidewall, if you are curious about what the correct number is for your car.

1. Drive it home and then siphon the gas out.
   It will be fine, just don't do it again.
2. Get a tow back to your home and then siphon the gas out.
   Too late, the car is already ruined.

If you accidentally put diesel in your gas-powered car, you need to act quickly. The longer you leave the diesel in your vehicle, the more damage it can do. However, don't drive the car as that can do more damage, so be sure to get towed home before siphoning all of the diesel out.

1. It happens when some windshield washer fluid gets near the battery.
   It is caused by high temperatures.
2. Your terminals have corroded.
   That is used to protect the battery.

Corrosion can come in many shapes and sizes from relatively minor cases to some cases where the entire battery is corroded. If you notice a bit of corrosion, you should clean it as if you let it continue to occur, it can potentially damage the battery.

1. Your car is "running-on."
   This is normal if you have been driving for many hours straight.
2. Yes, there is a ghost driving your car.
   You might have a problem with the ignition switch.

If your car continues running after you have turned the ignition off, it is called running-on. Something is causing the cylinders to continue igniting, which keeps the engine running. Commonly, this is when you use cheap gas in a car that requires higher octane fuel.

1. Leave it until it gets worse.
   Put some tape over it to prevent it from growing.
2. Fix it yourself.
   Get it repaired as soon as possible.

While a tiny chip will be barely noticeable, it is easy for them to get a lot worse very quickly. As a result, you should move quickly to get even the smallest chip replaced. If not, it could blossom into something much more expensive to fix.

1. Using baking soda in water
   Using vinegar
2. Using Coca-Cola or another similar soda
   They are all correct ways to clean a battery terminal.

While corrosion on your batteries can look bad, they are thankfully quite easy to clean. Using baking soda, vinegar or even Coca-Cola can help clean those terminals right up. Of course, if the corrosion is advanced, these methods might not be enough.

1. A problem with the electrical system
   Your car has been running too long.
2. Your air conditioner is broken.
   Power-steering fluid is leaking.

Smelling burnt toast in your car is a common experience when there is an issue with something in the electrical system. Often, this is an electrical short or burning insulation. These are issues which should be dealt with immediately.

1. A warning light
   Lights in the car are dim.
2. Slow accessories
   All are signs of a potentially faulty alternator.

Having a faulty alternator makes driving incredibly annoying, but at least it is easy to recognize. Slow accessories, a warning light or dim/flickering lights are all signs that you might have a faulty alternator.

1. You can't.
   You will feel the car tilt and should hear thumps.
2. The exposed rim will cause sparks.
   You will see the flat in the mirror.

While seeing a flat tire is a common way to realize you have one, many will be able to "feel" it while driving. Your car might tilt a bit and you should hear some louder thuds and thumps.

1. It alerts you of someone in your blind spot.
   It lets you know a bulb is burnt out.
2. Just leave it alone and it should stop.
   You need more headlight fluid.

While seeing a burnt out bulb is easy if you're out of the car, it is impossible to know if all lights are functional while you are driving. As a result, many vehicles come with a feature to speed up the signal light indicator to let you know one of the lights isn't functioning correctly.

1. Low coolant
   Overheated brakes
2. Too much revving of the engine
   Bad spark plugs

When driving up or down a mountain, you will be using your brakes a lot. Repeated hard breaking is common and can, unfortunately, lead to brakes overheating, which can emit a strong and foul smell.

1. There is air in the brake lines.
   You're not pushing hard enough.
2. The disc brake caliper is damaged.
   Low brake fluid

Nothing quite induces panic in drivers like feeling like your brakes aren't working. Having "soft" breaks can happen for a number of different reasons, but not pushing hard enough isn't one of them. Brakes should be fairly simple to press and should feel very strong and tight.

1. The exhaust is leaking.
   Your brake fluid is low.
2. The weather stripping (which protects the trunk from water and rain) is damaged.
   You overfilled your gas tank.

Every car has some weather stripping around the opening of the trunk to water from entering the trunk. If this lining is damaged, water could seep in and could lead to the development of mold.

1. A faulty starter
   The fan belt is loose.
2. Your fuel filter is clogged up.
   Misaligned front wheels

There are many different reasons for steering issues (such as worn steering components or even under-inflated tires). But of the options provided, only misaligned wheels could be responsible for handling or steering issues.

1. Your car and engine have a rough idle.
   Your engine is surging.
2. Your brakes are softer than usual.
   Your engine misfires.

A spark plug is responsible for helping start a car and ensuring it stays that way. If your engine misfires, it has a rough idle or your vehicle surges. No issue with your brakes should have much at all to do with your spark plugs.

1. Engine bearings that are worn out.
   An oil level that is too low
2. Your car recently got an oil change.
   A damaged oil pump

Dealing with low oil pressure in your car can be a frightening thing. There are several different reasons why you could be getting low oil pressure, including a damaged oil pump, a low oil level or worn out engine bearings.
