In this guide, we’ll cover fixing common car problems, offering step-by-step advice, pro tips, and product recommendations. Whether you’re a seasoned driver or new to car maintenance, these solutions will help you keep your vehicle in top condition and avoid unnecessary repair costs.
1. Dead Battery
A dead battery is one of the most frequent car issues and can happen when you least expect it. Whether your battery is aging, you accidentally left your headlights on, or cold weather has drained its power, dealing with this common problem doesn’t have to be a headache. Fixing common car problems like a dead battery is fairly simple, and having the right tools on hand can save you from waiting around for roadside assistance.
How to Fix It:
- The quickest way to get back on the road is by jump-starting your car. If you have jumper cables, connect them to a working vehicle’s battery. Attach the red (positive) clamp to the dead battery’s positive terminal and the black (negative) clamp to the negative terminal. Start the working car, and then try starting your car. Let the running car charge the dead battery for a few minutes before you attempt to start it.
- If you’re using a portable jump starter, you don’t need a second vehicle. Follow the manufacturer’s instructions for connecting it to your battery, then jump-start your car.
Pro Tip: Cold weather can weaken a car’s battery, so it’s important to check your battery’s health regularly, especially before winter. Keeping a portable jump starter in your trunk ensures you can get back on the road without relying on the help of others.

2. Flat Tire
A flat tire can strike anytime, anywhere—whether you’re on your way to work or driving home from a weekend getaway. Knowing how to handle a flat tire is essential for fixing common car problems on the road and ensuring you don’t end up stranded. While it might seem intimidating at first, changing a tire is a straightforward task once you get the hang of it.
How to Fix It:
- First, make sure you’re in a safe location on a flat surface, and turn on your hazard lights to alert other drivers. Before lifting the car, loosen the lug nuts on the flat tire with a wrench, but don’t remove them yet.
- Use a jack to lift the car until the flat tire is off the ground. Remove the loosened lug nuts and take off the flat tire. Align the spare tire with the wheel studs, place it on, and hand-tighten the lug nuts.
- Once the car is lowered back onto the ground, fully tighten the lug nuts in a star pattern to ensure even pressure.
Pro Tip: Spare tires often go unchecked for long periods, so it’s a good idea to inspect the pressure in your spare when you check your regular tires. This ensures you won’t be stuck with a flat spare when you need it most.

3. Squeaky Brakes
Squeaky brakes can be alarming, especially if you’re unfamiliar with brake systems. The squealing sound typically means your brake pads are worn out, but it can also be caused by dirt or moisture. When left unaddressed, worn brake pads can lead to more serious problems like damage to your rotors, so it’s important to take care of this issue promptly. Fortunately, fixing common car problems like squeaky brakes is something you can often do yourself.
How to Fix It:
- Begin by inspecting your brake pads. If they’re thinner than a quarter of an inch, it’s time to replace them. To change the pads, lift the car with a jack and remove the wheel. Use a wrench to unscrew the caliper and carefully slide out the old brake pads.
- Insert the new brake pads into place, ensuring they’re correctly aligned. Reattach the caliper and wheel, and then test the brakes to make sure they’re functioning properly.
Pro Tip: Brake pads wear down unevenly, which is why you should always replace them in pairs (both front or both rear) to ensure smooth, balanced braking and avoid premature wear on the remaining pads.

4. Overheating Engine
An overheating engine can be one of the most stressful issues for a driver, especially if you’re on the highway or in stop-and-go traffic. Overheating can be caused by various factors, including low coolant levels, a faulty thermostat, or a broken water pump. Regardless of the cause, fixing common car problems like this requires immediate attention, as driving with an overheated engine can cause serious damage.
How to Fix It:
- As soon as you notice the temperature gauge rising or see steam coming from under the hood, pull over in a safe area and turn off the engine. Wait for the engine to cool down completely before opening the hood.
- Once the engine is cool, check the coolant level. If it’s low, top it off with the appropriate type of coolant. If your car continues to overheat despite having enough coolant, you may have a more serious problem, such as a malfunctioning thermostat or a leaking radiator, and it’s best to seek professional help.
Pro Tip: Always carry extra coolant and water in your car, especially if you’re going on long trips. Regularly checking your coolant levels can prevent overheating and save you from major engine repairs.

5. Engine Won’t Start
Few things are more frustrating than turning the key and hearing nothing from the engine. If your car won’t start, it’s important to determine whether the problem lies with the battery, the starter, or the alternator. Fixing common car problems like this is often a matter of trial and error, but having the right tools will make it easier to pinpoint the issue.
How to Fix It:
- First, check the battery by attempting to jump-start the car. If the engine starts after a jump, your battery was likely the problem. However, if your car still won’t start, listen for a clicking noise when you turn the key. This often signals a faulty starter.
- If you suspect the alternator is at fault, you can test it using a multimeter or battery tester. If it’s not charging the battery properly, the alternator may need to be replaced.
Pro Tip: If your battery is more than three years old, it may be nearing the end of its lifespan. Regularly testing your battery’s health can help you catch problems before they leave you stranded.

6. Check Engine Light
The check engine light can cause anxiety for any driver, especially since it could mean anything from a loose gas cap to a more serious engine issue. Fixing common car problems related to the check engine light is often simpler than it seems, especially if you have access to an OBD-II scanner.
How to Fix It:
- The first thing to check is whether your gas cap is loose or damaged. A loose gas cap can cause the check engine light to come on. Tighten it and see if the light turns off after a few drives.
- If the gas cap isn’t the issue, use an OBD-II scanner to read the diagnostic codes and pinpoint the problem. Many auto parts stores offer free code readings, so you can get a clearer picture of what’s going on without paying for a mechanic’s visit.
Pro Tip: Don’t ignore the check engine light for too long, even if your car seems to be running fine. Addressing small problems early can prevent them from turning into bigger, more expensive repairs.

7. Shaking Steering Wheel
If you notice your steering wheel shaking or vibrating while driving, it could be due to unbalanced tires, misalignment, or suspension issues. This is not only uncomfortable but can also lead to uneven tire wear and reduced handling performance. Fixing common car problems like this can improve your car’s overall safety and make your driving experience smoother.
How to Fix It:
- Start by checking your tire pressure. Low or uneven tire pressure is one of the most common causes of steering wheel vibration. Inflate the tires to the recommended pressure level and see if the problem persists.
- If tire pressure isn’t the issue, your tires may be unbalanced, or your wheels may be out of alignment. In this case, it’s best to take your car to a professional for alignment or balancing.
Pro Tip: Rotating your tires regularly helps distribute wear evenly, which can prevent shaking and extend the lifespan of your tires.

10. Car Pulling to One Side
If your car pulls to one side while driving, it’s usually a sign of alignment issues or uneven tire pressure. Fixing common car problems like this can improve your car’s handling, increase tire longevity, and ensure a safer ride.
How to Fix It:
- Start by checking your tire pressure to ensure all tires are evenly inflated. Low or uneven pressure can cause your car to pull to one side.
- If the pressure is fine, your car may need a wheel alignment. Misalignment can happen over time due to hitting potholes, curbs, or general wear and tear, and it typically requires a trip to the mechanic to correct.
Pro Tip: Regularly schedule tire rotations and alignments as part of your vehicle’s routine maintenance to avoid uneven wear and improve handling.
