Owning a car and dealing with car problems go hand in hand, so knowing what constitutes a common issue, a minor fix, or a major problem is important. Some issues need to be addressed promptly before they worsen, while others are cosmetic, such as scratches and dents.
Our blog from the auto experts at Kennedy Transmission will answer many frequently asked questions about car problems, what you can do about them, and when it’s time to seek professional assistance!
Why Does My Car Make Strange Noises?
Cars consist of approximately 30,000 parts, and due to their frequent use and the diverse terrains they traverse, it’s quite common for even the smallest components to wear down. If you hear unusual noises coming from your car, they could stem from a range of issues. Learn below what might be the source of the strange sounds emanating from your vehicle:
- Brake issues. Grinding, scraping, and squealing noises while braking may indicate worn brake pads, rotors, or a worn brake pad indicator.
- Engine problems. Unusual knocking, squealing, or whining noises from under the hood could signal issues with the alternator, belts, pulleys, or potentially the engine.
- Exhaust issues. When accelerating, hearing rattling, roaring, or hissing noises may be from a loose or damaged exhaust system.
- Steering problems. If you notice whining or groaning noises when turning the steering wheel, this may indicate an issue with the power steering pump or other steering components.
- Suspension issues. Rattling, squeaking, or clunking sounds when driving over bumps or at higher speeds could be a problem with the suspension system, such as worn struts, sway bar links, or shocks.
- Wheel problems. Noises such as whirring, humming, or roaring during driving may indicate issues with wheel alignment or bearings.
Try to identify the source of the sounds and determine when they occur—if you’re idling, accelerating, braking, or turning. Give your car a once-over for any obvious issues, like loose parts, leaks, or signs of damage around the engine, undercarriage, and wheels. If the noise is loud or persistent, take your car to a mechanic for an inspection, because it won’t go away on its own.
What Does the Check Engine Light Mean?
Nothing feels quite like the dread that follows when your check engine light illuminates. But what does the light actually mean? When the check engine light comes on, it indicates that the car’s computer has identified a problem with the engine or emissions system. This could come from a wide range of issues, from minor problems to serious concerns. Other causes could be from:
- A loose gas cap
- Worn spark plugs
- Battery
- Mass airflow sensor
- Failing oxygen sensor
- Faulty oil valve
- Engine misfire
- Damaged catalytic converter
If your check engine light comes on, don’t ignore it. The first thing you should do is check the gas cap, just in case it’s loose or damaged. You can also read the diagnostic trouble code (DTC) with a car code reader or have a mechanic read it for you. Ignoring the check engine light could result in further damage and higher repair costs.
How To Fix Scratches on Your Car
Scratches on your car’s exterior are more than just a nuisance. They can cause even more damage if left unaddressed, such as rust. Flying rocks, debris, accidental bumps with another car or object, and improper cleaning can all lead to scratches. The easiest way to fix this is with touch-up paint.
Most car manufacturers offer touch-up paint that matches your car’s exact color. Simply apply it to the scratch after cleaning and letting it dry for a quick repair.
Scratch removal products are widely available at auto parts stores to help minimize shallow scratches. A shallow scratch, or surface scratch, is one that you cannot feel after running your finger over it, as they don’t penetrate the paint layer.
You can also invest in a polishing compound that can work wonders on these surface-level scratches. Gently buff it to blend the scratches with the surrounding paint.
Deep scratches that penetrate the clear coat or paint can lead to rust or peeling if they are consistently exposed to the elements. When the damage is severe or shows signs of rust, it’s time to have a professional take a look at it.
How To Fix a Dent in a Car
A minor dent doesn’t have to leave a big impact on your wallet! With a little effort and knowledge, you can often repair minor dents at home using everyday items.
A plunger, while a faithful steed in the bathroom, can be used here and can work wonders for smaller dents! Moisten the edges of the plunger, attach it to the car with the dent at the center, and gently pull to pop the dent back out—you may also want to wash the plunger first.
Believe it or not, a hair dryer can also help remove the dent! Heat the area with the tool, and then quickly cool it using compressed air or an ice pack. This can cause the metal to contract and snap back into place.
Have you tried these methods already and found that none of them worked? It’s time to contact professional help. Trained technicians have specialized tools and extensive experience to fix a complicated dent seamlessly.
How To Fix the AC in a Car and How Much It Costs
Minnesota winters are harsh, but summers can also be equally unforgiving without functioning air conditioning. If your car’s AC isn’t keeping you cool, it could be due to a few common issues, such as:
- Refrigerant leaks. Low refrigerant levels are often the primary cause of weak cooling.
- Broken compressor. The compressor is a key component of the AC system—if it fails, the air conditioning won’t work.
- Clogged filters. A dirty air filter can block airflow, making the air conditioning less effective.
Some AC issues are easy to handle on your own, such as replacing filters or fuses and checking if the refrigerant levels need topping off. However, issues like compressor failure or refrigerant leaks require professional equipment and expertise, which means it’s time to schedule an appointment. Learn more about car maintenance during humidity and hot weather from our auto blog.
How Much Is It To Fix an AC in a Car?
Different AC components vary in cost, particularly depending on the amount of work required and the extent of the damage. Recharging the refrigerant typically costs between $100 and $300. Major repairs, such as replacing the compressor and repairing or replacing the condenser, can range from $500 to $1,000 and $450 to $1,000, respectively.
How To Fix the ABS Light on a Car
The Anti-lock Braking System, also called ABS, plays a crucial role in your car’s safety. The ABS light typically indicates a problem with the sensors that monitor wheel speed or the ABS control module. If the light illuminates, try restarting the car. This may reset the ABS light in some cases if the issue was an error. You can also check your brakes—look for low brake fluid levels or worn-out brake pads.
Problems with the ABS can compromise your vehicle’s ability to stop safely, especially on the icy or wet roads so common in Minnesota. If the ABS warning light persists, schedule an appointment with a professional to address the issue promptly.
Car Alternator Problems: How To Diagnose and Fix Them
The alternator powers everything from your headlight to your car battery. If something seems off with the alternator, or you notice the following signs, it’s time to act quickly:
- Flickering or dimmed headlights
- Warning lights on the dashboard
- A dead battery that won’t hold a charge
You can handle a few minor fixes yourself, like cleaning the battery terminals or swapping out the serpentine belt. If the terminals are corroded, giving them a good clean can help the alternator do its job. And if the serpentine belt looks worn or feels loose, it’s time to replace it since it’s what keeps the alternator running smoothly.
If the alternator itself is failing, replacing it is necessary. Costs usually range from $500 to $1,000, depending on your vehicle’s make and model.
