Why You Shouldn't Ignore Warning Lights

Never ignore your car's warning lights. Diagnose the lights and fix the faults they indicate. Otherwise, the following consequences might ensue.

Costly Car Damage

Some warning lights indicate emerging faults that can lead to costly damages. Diagnosing such warning lights allow you to repair your car before the faults worsen. Below are a few examples of such warning lights.

Oil Pressure

Low oil pressure means the car's engine is not getting the needed oil. That might be the case if the car doesn't have enough oil or if the oil is not circulating. The car engine uses oil for lubrication and cooling. Thus, low oil pressure means overheating and friction damage. Costly engine damage might ensue if you continue to operate the car under those conditions.


Some car parts, such as transmission and engine, work best within specific temperature ranges. The high-temperature warning alerts you that the car is operating above safe temperatures. Again, engine and transmission damage will ensue if you don't correct the fault.

Increased Environmental Pollution

Cars that burn fossil fuels emit exhaust gases that affect the environment. Car manufacturers design engines and exhaust systems to limit dangerous gas emissions. However, damage to the engine might produce more dangerous gases than normal.

The check engine light is the premier warning for engine problems. Thus, driving a car with the check engine light might release unusual amounts of gases into the environment.

Increased Risk of Accidents and Injuries

Some warning lights alert you to dangerous situations that increase your accident risk. Others increase your risk of severe injuries in accidents. Below are a few examples.


The brake warning light may mean a fluid, electrical, or mechanical problem with the brake system. Any of these issues can affect your braking system and cause an accident in an emergency.

Traction Control

The traction control system ensures the car's tires don't lose grip on the road, even in difficult situations like wet roads. A brief appearance of the warning might not mean much – it may just mean the traction control is working. However, persistent traction control warning lights might mean a fault with the system that can lead to loss of traction and an accident.


The airbag absorbs the car's impact during an accident, reducing your risk of severe injuries. An airbag warning light means the airbag system is faulty. Such an airbag might deploy without warning, deploy too slowly, or fail to deploy during an accident. Such malfunctions may lead to more injuries than you would otherwise sustain with functional airbags.

About Me
what to car sounds mean?

I have an older car that is constantly in the shop. Yes, this car does cost me a bit each year to keep on the road, but what I pay in repairs is much less than what I would pay to buy a new car. I have learned a lot over the years of driving this car. I have found out what just about any sound means and what it takes to make those repairs.
