#1. Check Engine Light

Check Engine Light

Let’s start with the worst. The check engine light is usually in the shape of a silhouetted engine, or sometimes it’s even harder to miss the capitalized “CHECK ENGINE” message, this is the one car owner who hates it the most.

It looks scary but this warning light has more than one possible meaning as it could be anything related to your car engine and exhaust system. The potential problem could be as small as a loose wire, a loose or damaged gas cap, or a faulty oxygen sensor. Or something much more serious and wrong with the engine itself.

If the check engine light comes on while driving and everything seems fine with the car, don’t panic, but don’t ignore it either. Take the vehicle to a mechanic to run a diagnostic test and fix the problem.

Since 1996, every new car and light truck sold in the United States has been required by law to be equipped with an On-Board Diagnostic (OBD) system. This is a computer that monitors emissions levels and other main engine components.

It’s easier to find a problem with an OBD scan – something as simple as tightening the gas cap could solve the problem. It also prevents an emission-spitting vehicle from driving without the driver knowing there’s a problem lurking under the hood.

There are many reasons why the check engine light may come on. Some of the most common reasons include:

  • Loose or damaged gas cap.
  • Faulty oxygen sensor.
  • Malfunctioning catalytic converter.
  • Damaged spark plugs or ignition coil.
  • Failing mass airflow sensor.
  • Broken or damaged vacuum hose.
  • Malfunctioning EGR valve.
  • Faulty thermostat.

If the light comes on and the vehicle suddenly starts to erratic or makes strange noises, stop immediately and request towing service. This means that there is a far more serious problem, such as a misfire that could permanently damage the engine of the car. Ignoring a flashing check engine light could mean putting yourself at risk and ruining your car’s powertrain.

#2. Battery Alert Warning Light

car-battery-warning-light

The battery warning light on a car’s dashboard is designed to alert you to a problem with your vehicle’s battery or charging system. If your car battery light comes on when you start the car, you’re safe! It is perfectly normal for this light to come on when you first turn on your car. The light goes out after a few seconds.

If your low battery warning light comes on while driving, it means your battery is no longer being charged by the alternator and is only running on its own charge. This means your car will only run on battery power, which will eventually run out and bring your car to a standstill.

The first thing you should do is turn off any electrical systems in your car that you don’t need. That means turning off the stereo, air conditioning, heated seats, and anything else you charge in the car. If it’s safe to drive without your headlights and you can see clearly, turn them off as well to save power.

An illuminated battery light can be due to several issues, including:

  • A loose or corroded battery cable
  • A problem with the alternator or voltage regulator
  • Damaged cells or plates in the battery
  • Faulty wiring in the car’s electrical charging system

A battery light on the dash basically means there is a battery charging problem. Your car is not getting enough voltage from the car battery to function properly.

Don’t be fooled if the battery light comes on but the car starts and drives normally. There could be a long-term problem with the battery itself, or potential problems with the wiring, alternator, or other vehicle electrical components. You have to fix the problem as soon as possible by taking the car to a mechanic to diagnose and fix the problem.

#3. Engine Temperature Warning Light

Engine Temperature Warning Light

The engine temperature warning light, which looks like a thermometer or simply the word “TEMP”, illuminates when your vehicle’s engine is running at a temperature that is too high – in other words, your engine is overheating.

If your vehicle’s cooling system is working properly, this should never occur. However, a problem with the cooling system or low coolant can cause the engine to overheat, which leads to engine damage. Since an overheated engine can cause major and often irreparable damage, you should act immediately.

Typically, this light gives you at least a brief warning of a serious problem. Watch the light closely for the next mile or two, and if the warning light does not go off by then, stop and turn the engine off.

In any case, it is best to call your local service center or roadside assistance for assistance.

#4. Transmission Temperature Warning Light

Transmission Temperature Warning Light

The transmission temperature warning light indicates that the internal pieces of your gearbox are reaching a critical point, which can lead to transmission failure. If the light comes on, you have to be cautious and avoid steep grades or stop-and-go traffic.

The ideal maximum transmission temperature is 200 degrees Fahrenheit, and for every 20 degrees above 200, the lifespan of the transmission is reduced by a factor of 2. This might be caused by excessively heavy towing, low transmission fluid levels, or, more seriously, excessive wear on the inner workings of the transmission.

The urgency of the situation can be determined by the color of the warning light, with red indicating a more urgent issue that requires immediate attention.

Continuing to drive with the transmission temperature warning light on can cause further damage to the transmission. It is recommended to have the vehicle inspected by a mechanic as soon as possible to diagnose and fix the issue.

#5. Oil Pressure Warning Light

Oil Pressure Warning Light

Generally, an oil pressure warning light looks like a genie lamp or an old fashion oil can. This warning light indicates there is a problem with your engine oil, it could be low engine oil or low engine oil pressure in the system.

This light comes on the dashboard when the oil pressure in the engine is drop to a low level and it could be a serious issue. If the oil pressure warning light comes on, it is best to turn off the vehicle and not use it until the problem is fixed. Driving with low oil pressure can quickly destroy the engine.

It is recommended to allow the car to sit for at least 10 minutes before checking the oil level while parked on a semi-level surface.

If the engine’s dipstick shows oil levels are low and adding oil turns the light off, then you’re in luck. If that doesn’t do the trick, or the light comes on shortly after you’ve added oil, it’s smart to get the issue checked as soon as possible.

There are several possible scenarios when the oil pressure warning light illuminates. The most common reasons why the low oil pressure light turns on are a low oil level, a malfunctioning oil pump, or a major engine problem.

To prevent the oil pressure warning light from illuminating, it is recommended to ensure that the vehicle receives routine maintenance, including regularly scheduled oil changes.

#6. Tire Pressure Warning Light

Tire Pressure Warning Light

The tire pressure warning light is an indicator that your tire pressure is too low or too high. The light is usually yellow or amber and resembles a cross-section of a tire with an exclamation point and/or the letters “TPMS“.

If the light comes on, it means your tires could be underinflated, which can lead to undue tire wear and possible tire failure. You should check your tire pressure and inflate or deflate your tires as needed to bring them within the recommended range.

However, most passenger cars will recommend 32 psi to 35 psi in the tires when they’re cold.

If the tire pressure is nominal and there are no leaks, but the TPMS warning light is still on, you could attempt driving for at least 10 minutes at a speed of 15 mph or more to reset the system. If the TPMS light flashes for a minute and then stays illuminated, it means something is wrong with your TPMS system.

#7. Brake Warning Light

Brake Warning Light

The brake warning light on a car’s dashboard can indicate one of several things. The most common reasons for the brake warning light to turn on are that the parking brake is engaged, or the brake fluid level is low.

If the brake warning light comes on while driving, the first thing to do is to carefully pull over in a safe area and turn off the car.

The emergency brake should be checked first. You can not continue driving and ignore the brake light, as this can cause more damage to the braking system and be very dangerous.

The vehicle should be towed to a trusted mechanic for inspection. Since the brake warning light can mean various things, it’s best to have a brake expert look to confirm the real issue before other warning signs appear.

#8. Traction Control Malfunction Warning Light

Traction-Control-Malfunction-Light

The Traction Control Malfunction Light illuminates when there is an issue in the traction control system.

It indicates that there is an issue with the traction control system, which helps to keep the vehicle in control if one or more wheels lose traction while driving. The light may come on due to various reasons, including a defective ABS system, wheel speed sensors, or reductor ring.

While this won’t affect your everyday driving, you should get it checked soon to make sure your vehicle will operate safely in inclement conditions.

#9. Airbag Warning Light

Airbag Warning Light

The airbag light indicates that something is wrong with one of your airbags or the entire airbag system. This means that it’s probably not safe to drive with the airbag light on.

After all, if the airbags don’t deploy and you get into a crash on the way to get it fixed, you’ll be at much greater risk for injury or death. Diagnosing the cause isn’t always easy, so it’s best to let the experts handle it.

You should get your car checked out immediately! Your car’s airbags keep you safe during accidents, so make sure they are working properly.

#10. Anti-lock Brake System Warning Light

Anti-lock Brake System Warning Light

ABS stands for anti-lock braking system and when the ABS warning light comes on in your car’s instrument cluster, it means that the anti-lock braking system has been deactivated due to a malfunction.

Your car’s regular brakes should work fine, but the anti-lock brakes, which prevent the wheels from locking when you brake, don’t work. If your vehicle has stability control and traction control, these will also be disabled as these systems rely on the same wheel speed sensors as the anti-lock braking system.

The four most common reasons that usually cause this light to come on are a faulty ABS module, low levels in the fluid reservoir, faulty wheel speed sensors, or the system is off.

#11. Low Fuel Warning Light

Low Fuel Indicator Light

An illuminated dashboard light in the shape of a fuel pump lets you know that your fuel tank is almost empty.

The low fuel warning light has one purpose: to let drivers know their fuel tanks are getting low. When the yellow gas pump symbol lights up, you need to drive to a gas station and fill up your fuel tank.

Your car’s drivability will not be affected, and you can still drive safely. Just don’t plan on driving too long – you don’t want to find yourself out of fuel and stranded.

If your light stays on even when the fuel tank is full, your fuel level sensor may need service. Try higher-quality fuel. Lower grades have more contaminants or may contain traces of water that can damage your sensor.

If you’re still having trouble, it would be a good idea to take your car to a mechanic.

#12. Automatic Shift Lock or Engine Start Indicator Light

Automatic-Shift-Lock-warning-light

The automatic shift lock light is an indicator of your car’s shift lock release in automatic transmissions. This light is also known as the engine start indicator warning light. It has two purposes: It indicates that you need to apply the brake to start the vehicle’s ignition or shift out of neutral.

For your safety, the automatic transmission has a shift lock system that prevents the transmission from being shifted from P (Park) to R (Reverse) when the brake pedal is not depressed. To shift the transmission from P (Park) to R (Reverse): Press and hold the brake pedal.

So, press the brake pedal, then change gears or start the ignition, whatever you want to do.

#13. Security Indicator Light
