All My Dash Lights Came On While Driving – Why & What To Do

More features and equipment are included in modern cars than before. Indeed, the electrical systems in current automobiles rely on various sensors wired to dashboard warning lights and symbols.

If any light glows, it means your car has problems with its components or engine.

Yet, what happened if all my dash lights came on while driving? What should you do in that situation? If these questions boggle your mind, you are in the right place.

This article will provide reasons and tips to deal with the issue! Let’s start exploring!

Why All My Dash Lights Came On While Driving?

All My Dash Lights Came On While Driving

Several factors can make all dash lights come on while driving. The most typical reason is a malfunctioning alternator.

A dead battery is the second most frequent problem. Although unlikely, a third option is that the wiring in your automobile has an electrical short.



The car battery primarily supports the electrical system in our cars. As a result, the entire electric connectivity in the vehicle is disrupted when a battery failure occurs.

This way, it might cause all dash lights on and the automobile to die.

Moreover, when there is a battery problem, you cannot start the engine or any other device that relies on battery energy. You must replace a new battery once you spot signs of car batteries being faulty.



The alternator is a crucial part of a car engine. It converts mechanical power into electrical energy to power the automobile engine.

The malfunctioning alternator prevents the necessary parts from receiving electricity. It stops functioning and no longer charges the battery.

When the battery runs out, the automobile engine likewise stops running due to the battery’s electricity being turned off.

Before this occurs, all of the dash lights illuminate, alerting us to the serious state of the vehicle.

An Electrical Short

An Electrical Short

Your car cannot operate normally when the wiring has an electrical short.

The warning system might not recognize which parts have trouble because all components don’t work. That makes all dashboard lights on.

What To Do If All My Dash Lights Came On When Driving?

A dashboard warning light often doesn’t indicate that the car will break down right away or that it’s dangerous to travel short distances, such as to a collision repair shop.

Yet, you shouldn’t try to drive long distances in this situation. The more time that goes by, the more likely it is that the problem may worsen and spread.

Thus, you need to go to the nearest auto shop to check.

If you cannot find one, stop at a place allowing the car park to do some simple inspection for your car, including checking the car battery and alternator.

Then, you can quickly describe your car situation to a car service to ask for their help. Once again, please don’t try to drive the car for a long distance!

Some Dashboard Warning Lights

Low Fuel Indicator

Almost all drivers are familiar with this symbol. It only indicates that your vehicle is running low on gas.

You might estimate the way to go home or to the nearest gas station to ensure you have enough fuel to go there.

In addition, most cars feature a triangle-shaped arrow on the fuel gauge adjacent to the gas pump icon. The direction of this arrow shows which side of the car the gasoline tank is on.

Tire Pressure Warning Light

This symbol indicates that you should take care of the pressing factor in at least one of your tires since it is either too low or excessively high.

Driving with either low or excessive tire pressure is risky and can further damage your car. Generally speaking, the ideal tire pressuring factor should be between 30 – 35 psi.

Oil Pressure Light

This sign denotes a problem with the system that controls the oil pressure in your car.

It’s a high chance that you’re running low on oil or that your oil siphon isn’t pumping out enough fluid to lubricate the inside surfaces of your car properly.

As a result, your motor may quickly wear down without the proper oil. In this case, this has to be fixed as soon as possible.

Traction Control Light

The traction control light demonstrates that the footing control framework for your vehicle is engaged.

The foothold control framework uses your automatic stopping device framework to determine which wheel is rotating more quickly than the other.

If anything other than a wheel is sliding, it will apply the brakes until it regains its footing. This is often helpful if it starts to rain or snow while driving.

Engine Temperature Warning

This shows that your engine is overheated if you notice this picture appearing.

Although it may happen for several reasons, your coolant (also known as a liquid catalyst) is most likely to blame. To prevent more harm, it is critical to take action right away.

Engine Warning Light

There are several potential causes for your check engine light to come on. An open, slack, or broken gas cap allowing fuel to evaporate can be the reason.

However, occasionally it denotes a more serious problem, such as low oil pressure or overheating.

Instead of this indicator, certain automobile dashboards would notify “Check Engine”.

If the engine warning light is blinking or is red, you should immediately pull over! A flashing light often tells you that you have a significant issue that, if ignored, might seriously harm your engine.

Battery Alert

This graphic demonstrates an issue with the vehicle’s charging structure. Your battery usually won’t be the offender.

While it could show that your battery link is free or damaged, it might signal that your alternator belt is damaged.

You may notice that your clock is blurring or that your headlights are dimming on the off chance that it is your battery. In the event that you wait around for too long, your car might completely break down.

Thus, you should maintain the battery periodically, including checking the battery health, cleaning corrode cables, etc.


Some car owners might ask why all my dash lights came on while driving.

It can happen for various reasons, stemming from the battery, alternator, and electrical shorts. You can quickly check yourself if you don’t have time to bring your car to an auto shop.

Yet, you should ask for a professional mechanic’s help to handle the problems as soon as possible.

Otherwise, your car will have more serious issues, making it unable to start or malfunctioning more engine parts.
