Why Drivers Should Not Ignore Their Car’s Check Engine Light

The check engine light is one of those confusing warning signs that makes many motorists wonder what could be the cause. Since this warning sign can be triggered by many problems, drivers often assume it is not urgent. Others believe the light will go away and postpone repairs. But what is the cost of ignoring the check engine light? Does delaying diagnosis increase costs down the road?

The check engine light could be a sign of a major mechanical problem that might cost a fortune. However, it might as well be caused by a small issue that takes only a few minutes to fix. This means that prompt diagnosis is critical even when the car owner is on a tight budget. This post will explain the real cost of ignoring the check engine light.

Ignoring a Small Car Problem Makes It Worse and More Expensive

Many car owners have driven vehicles with the check engine light on at some point. They assume that the vehicle will endure until they get time and money to visit a repair shop. However, delaying repairs can actually cause more damage and increase repair expenses. For example, if a car owner ignores a check engine light caused by a misfiring engine, the engine could damage the spark plugs and pistons.

In extreme cases, the engine will damage more internal components and eventually fail. Car owners living in Oakland County can seek timely auto repair in Pontiac, MI, at a fraction of the cost instead of ignoring the warning light. A quick diagnosis and timely repair can prevent expensive replacement of parts.

Ruin the Catalytic Converter

Mechanical issues that could affect the catalytic converter usually trigger the engine light. Examples include a bad oxygen sensor and a misfiring engine. If a driver overlooks these problems, the car emits harmful gases beyond what the converter is designed to handle.

As the converter strains to clean the harmful emissions, the inner components get damaged. This means the car owner will have to fix the initial problem and also replace the catalytic converter to avoid failing the emission test.

High Cost at the Pump

A faulty oxygen sensor can trigger the check engine light. If the driver ignores the problem, the engine might run rich and consume more fuel. This translates to low miles per gallon and gradual internal engine damage. If the driver postpones diagnosis for a few weeks, the damage will be severe, and they will have wasted more money at the pump. Fixing the sensor and other minor issues will generally cost less than repairing severe damage and refilling the car more.

Unexpected Failure

An engine light can indicate a serious problem that could make a car stall. Nobody wants to be stranded on the road waiting for towing service. So instead of waiting for the problem to worsen and cause an unexpected breakdown, car owners should seek a diagnosis as soon as the check engine light turns on. The emergency repairs and towing service costs will be more than the cost of seeking early diagnosis and repair services.

Check engine light does not always spell doom. It could be a sign of a minor or major engine problem. Since car owners cannot tell the cause, they should seek a diagnosis immediately. The mechanics will solve the problem and ensure the vehicle runs smoothly.
