10 Signs of Car Problems That Need Immediate Attention

10 Signs of Car Problems That Need Immediate Attention

If you’ve recently bought a car and it’s already acting up, you are not alone. New car issues are more common than you may think. Before we dive into the top 10 warning signs, you may also want to check out our guide on how long it takes to get a car serviced, just so you know what to expect.

1. Common Dashboard Warning Lights (Check Engine Light)

Modern cars are equipped with a self-run diagnostic system for many of the major components. When there’s a fault, a warning light will illuminate on the dashboard to tell you something is wrong. Here are some of the most common warning lights and their meanings:

  • Check Engine Light: Engine or emissions issue (Serious fault if the light is blinking)
  • Oil Pressure Light: Low oil level or pressure
  • Battery Light: Charging system malfunction
  • Brake Warning Light: Low brake fluid or brake system malfunction
  • ABS Light: Anti-lock braking system fault
  • Coolant Temperature Warning: Engine overheating
  • Tire Pressure Light (TPMS): Low tire pressure or faulty sensor
  • Airbag Warning Light: Malfunction with the airbag system
  • Traction Control Light: Traction or stability issue
  • Service Vehicle Soon: General maintenance required
  • Transmission Temperature Light: Transmission issues related to overheating or low transmission fluid levels

Your owner’s manual should show you the varying lights your car offers, or you can find the information online specific to your vehicle. Once a warning light comes on, you need to have the codes scanned with a special computer to find out what the fault is.

Repairs should be made immediately to prevent further damage. For example, by continuing to run an engine with faulty spark plugs, you allow damage to the catalytic converter, which can be extremely expensive to replace.

2. Strange Noises

It’s important to listen to the sounds coming from your vehicle, as these can tell you early on if there’s a problem. Here are a few common sounds you may encounter:

  • Squealing or squeaking: Sign of worn brake pads, defective belts or worn suspension parts
  • Engine knocking or tapping: Strange noises can indicate engine damage and need to be looked at immediately
  • Grinding: Warped brake rotors or transmission problems
  • Clunking or rattling: Component may be loose or there could be a suspension issue
  • Whining: Noises while driving can indicate a transmission or power steering failure

When dealing with strange noises, it’s important to pinpoint where they are coming from. Once you narrow down the system involved, it will be much easier to determine what needs to be fixed.

3. Unusual Vibrations or Shaking

Vibrations while driving could indicate simple tire issues or larger suspension problems. There could also be brake issues involved, especially if the shaking is noticed most when pushing on the brake pedal.

To prevent costly repairs and ensure everyone’s safety, you want to have the vehicle inspected immediately. Ignoring these signs can cause faster wear on other parts and make driving more dangerous over time.

4. Fluid Leaks

Fluid Leaks

Automotive fluid leaks are not only bad for the environment but also put stress on the system that has low fluid levels. The easiest way to determine what’s leaking is to look at the color of the fluid.

  • Amber or light brown: Engine oil is amber when it’s fresh, but turns brown or black when it ages
  • Red or pink: Transmission fluid is bright red when fresh, but turns dark brown with a burnt smell when it’s older or contaminated
  • Pink, orange or green: Coolant or antifreeze color varies by type, but green tends to be the most common, while most will have a sweet smell
  • Yellow or clear: Brake fluid is light yellow or clear when new, but it can darken over time
  • Slightly blue or clear: Windshield washer fluid is often light blue and smells like cleaner
  • Red, amber or light brown: Power steering fluid looks similar to transmission fluid
  • Dark brown or black (thick): Gear oil has a strong sulfur smell; it’s found in differentials and manual transmissions

Fluid leaks can lead to serious damage if left unchecked. Low fluid levels can cause overheating, loss of lubrication or even complete system failure in parts like the engine, brakes or transmission.

5. Poor Performance, Loss of Power or Engine Stalling

When the vehicle’s performance is lacking, it’s a sure sign that something is wrong. You may notice difficulty accelerating when you push down on the gas pedal, engine stalling or reduced fuel efficiency.

These problems are often related to the fuel system, engine problems or the ignition system, such as the spark plugs or coils. There may also be a clogged filter that needs to be replaced.

By continuing to run the engine like this, you not only lose money because of the drop in fuel economy, but you also face larger repairs later that are going to drain your bank account.

6. Unusual Smells

Just as you want to pay attention to bad sounds, you should also be on high alert for unfamiliar odors. Here are some common smells that occur during car problems:

  • Burning smell: Worn brakes and oil leaks can cause burning odors
  • Sweet smell: A coolant leak creates a sweet smell
  • Rotten egg smell: When the catalytic converter goes bad, it often creates a noticeable sulfur smell
  • Gasoline smell: Smelling fuel in or out of the car can point to a dangerous leak
  • Moldy smell: Typically a sign of mildew in the air conditioning system or cabin air filter

If you notice a strange smell, don’t ignore it. Odors can signal serious problems under the hood. Pull over safely, check for visible leaks or smoke and have the vehicle inspected by a mechanic as soon as possible.

7. Steering Problems

Steering Problems

If the car suddenly has difficulty steering, you notice a wheel pulling or if there’s excessive looseness, you should also pay attention. The wheel alignment may be off or there could be low tire pressure, both of which affect the vehicle's safety. There’s also the chance that there is a power steering fluid leak occurring.

First, you should make sure you have properly inflated tires. If all looks well with the tires, we recommend having a technician inspect the car to prevent potential safety hazards.

8. Brake System Issues

If you notice trouble stopping when you apply the brake pedal, there could be issues with the system. You may also notice squeaky brakes or a spongy pedal. Brake fluid leaks are a common reason for trouble stopping, along with worn brake pads or rotors.

Because of the critical safety implications of braking problems, it’s vital to have a professional inspection performed. Expert brake services will include a complete evaluation of the system. The technician will look at the pads, rotors, brake lines and master cylinder to find any problems.

9. Transmission Troubles

Transmission fluid leaks, delayed shifting, slipping gears and unusual sounds should all be looked at immediately. Car owners may be able to have a low-cost fix if the problem is caught early on and can prevent a transmission replacement, which is expensive and time-consuming.

To keep the car running smoothly and to prevent transmission problems, regular maintenance is critical. Make sure you follow the manufacturer’s recommendations for transmission service, including flushes.

10. Electrical System Issues

If you see a dashboard light, such as the stability control light, you may only be looking at an electrical problem. With today’s sophisticated cars, the electrical system is responsible for keeping the engine running smoothly. You may notice dimming lights, malfunctioning accessories or battery problems, apart from the engine issues.

In some cases, a code scanner will be needed to read trouble codes. If the engine cranks slowly or won’t start at all, there may be an issue with the charging system, such as the battery or alternator. Otherwise, it may be something related to the ignition system, such as a faulty starter motor, a bad ignition key or other electrical components.

You can try to replace the battery to see if that fixes the issue, but most of these problems should be dealt with by a professional mechanic.

Warning Signs You Might Be Driving a Lemon Car

Warning Signs You Might Be Driving a Lemon Car

There are many types of problems covered by the Lemon Law in CA, so it’s important to know what may be included. Here are some criteria to keep in mind:

  • A significant defect affects the car’s safety, value or drivability
  • The car is covered by the manufacturer’s warranty
  • The defect begins within 18,000 miles or 18 months of taking ownership of the vehicle
  • The car has been in for multiple repair attempts without a remedy
  • The car has been in the shop for more than 30 days for a single problem

While most Lemon Law claims are for new cars, there are some provisions for used cars as well. To file a used car Lemon Law claim in CA, the vehicle would need to be covered under a warranty.

What Is a Lemon Car in California?

What is a lemon car and can you expect compensation? To qualify for coverage in California, your vehicle must:

  • Be purchased or leased new or certified pre-owned in California
  • Be covered by the manufacturer’s original warranty
  • Have a defect that continues after multiple repair attempts (four for the majority of cases, but only two with a serious safety-related concern)
  • OR be out of service for 30+ total days for repairs

If you live outside of California, you want to research local laws as some states don’t have the same level of protection for consumers. Some problems that may lead to a Lemon Law claim include, but are not limited to:

  • Engine failure
  • Repeated stalling
  • Malfunctioning oxygen sensor
  • Failing transmission
  • Brake system defects
  • Steering malfunctions
  • Defective headlights or fog lights
  • Overheating engine
  • Exhaust system malfunctions
  • Cooling system troubles

It’s vital that you know what to do if you have a lemon because time is of the essence. For this reason, we believe that you need a lawyer for Lemon Law claims.

Can I Get a Refund for a Defective Vehicle in California?

Yes – if your vehicle qualifies under California’s Lemon Law provisions, you may be entitled to a full or partial refund. The average Lemon Law settlement in California is between $40,000 and $50,000, but these amounts depend on your type of car and the defect.

A Lemon Law buyback may include the full purchase amount, your down payment, already made monthly payments, the loan payoff, registration fees, sales tax and towing or rental car costs, if applicable. You may also be entitled to a replacement vehicle that compares to what you are currently driving. In some cases, usually for minor faults, you may prefer the cash-and-keep settlement instead.

Is It Time to Talk to a Lemon Law Lawyer?

Hopefully, you’ve done your part to keep up with regular car maintenance and you should be able to expect a good-running vehicle. When that doesn’t happen, it’s time to take action. Whether you are dealing with a flashing Check Engine Light, a faulty oxygen sensor or other engine-related problems that can’t be repaired, it may be time to speak with an attorney.

FAQ

How Do I Find Out What Problems My Car Has?

Unless you are a mechanic, you may not know the difference between a clogged radiator and severe engine damage. For that reason, it’s best to have an expert technician look at your car if you are experiencing trouble.

How to Know if a Car Is Bad?

We recommend learning how to avoid a lemon car in the first place, so you never have to deal with these issues. Buy your vehicle from a reputable dealership and ask about the warranty coverage. It’s also good to perform a vehicle history check if you are purchasing a used car.

How Do You Know if Your Car Is About to Break?

It can be difficult to know unless you are a mechanic. For example, a Check Engine Light can come on for something as simple as a loose gas cap, but it could also be some major issue with the vehicle’s wiring. You should never assume that you know what’s going on with the car’s engine or other critical parts. It’s always better to be safe and have it checked out.

What Is a Red Flag When Buying a Car?

If the seller doesn’t have the title or it’s not in their name, you should be wary. You also want to take a used car to a mechanic for a pre-purchase inspection to see if there are any issues to be aware of. If the seller won’t let you take the car to a mechanic, you may want to purchase from someone else.

What Car Problems Are Most Common in Lemon Law Claims?

Lemon problems range from a rising temperature gauge and an overheated car because of a faulty water pump or other engine malfunctions. They could also be issues as simple as electrical glitches to body corrosion. Any significant defect that affects the safety, value or use is covered if the other requirements are met.
