Your car’s engine relies on a crucial component to start and run efficiently—the ignition coil. It might be a small device, but its role in the vehicle’s ignition system is massive. If you’re experiencing engine misfires, rough idling, or trouble starting your vehicle, a faulty ignition coil might be the culprit.
In this article, we’ll explore the function of an ignition coil, how to identify a failing one, and when to replace it. Plus, we’ll answer the most common questions about this vital part of your car’s ignition system.
What Is an Ignition Coil in a Car?
An ignition coil in a car is an electrical transformer that converts the car battery’s 12 volts into the thousands of volts needed to spark the spark plugs. This spark ignites the air-fuel mixture in the engine’s combustion chamber, powering your vehicle.
In modern vehicles like the Kia EV5 FWD and Kia Sportage HEV, ignition coils are more efficient and often dedicated to each cylinder, enhancing performance and fuel efficiency.
Ignition Coil in Car Symptoms: How to Tell It’s Failing
A failing ignition coil can cause a range of issues. Some common ignition coil problems symptoms include:
-
Engine misfires
-
The check engine light turns on
-
Poor fuel economy
-
Rough idling
-
The car won’t start or has trouble starting
-
Reduced acceleration or power loss
These symptoms may worsen over time, affecting the performance of vehicles like the Kia Sportage Alpha or Kia Stonic EX Plus.
Ignition Coil in Car Replacement: When and Why
The replacement of an ignition coil depends on usage, vehicle type, and driving conditions. On average, ignition coils last around 100,000 miles but may wear out earlier.
Signs it’s time for replacement:
-
Frequent misfiring or stalling
-
The engine light stays on
-
Diagnostic trouble codes related to ignition
When replacing ignition coils in vehicles like the Kia Carnival Executive, it’s wise to also inspect spark plugs, as both components work closely together.
Driving with a Bad Ignition Coil – Should You?
Driving with a bad ignition coil is not recommended. It can lead to:
-
Engine damage due to misfires
-
Increased emissions
-
Poor fuel efficiency
-
Complete breakdown
If you suspect coil issues, schedule a service using Kia’s online service appointment form or submit an online inquiry for quick assistance.
Ignition Coil vs Spark Plug: What’s the Difference?
Many confuse ignition coils with spark plugs, but they serve different roles:
-
Ignition Coil: Generates high voltage.
-
Spark Plug: Receives that voltage to create the combustion spark.
In essence, the ignition coil powers the spark plug. Faults in one can affect the other, which is why both should be checked if your vehicle is misfiring.
Why Quality Parts Matter
When replacing ignition components, always use high-quality OEM parts. This ensures your vehicle, whether it’s a Kia Sportage FWD or Kia Sportage L, performs efficiently and safely.

-
Typically up to 100,000 miles, but factors like driving habits and weather can shorten its life.
When should I replace my car ignition coil?
-
If you notice misfiring, poor acceleration, or engine warning lights.
What causes ignition coil failure?
-
Heat, vibration, and moisture are common culprits.
Can I replace an ignition coil myself?
-
Yes, if you’re mechanically inclined. However, professional service is recommended.
Is it expensive to replace ignition coils?
-
Costs vary by model. For Kia vehicles, consult the Kia Port Qasim price list.
Final Thoughts
The ignition coil is more than just a part of your car—it’s the heart of the ignition system. Whether you drive a hybrid like the Kia Sportage HEV or a spacious SUV like the Kia Carnival Executive, keeping your ignition system in top condition ensures smooth performance, better fuel economy, and longer engine life.
Regular maintenance and timely replacements, combined with protective services like glass coating and undercoating, can help you get the most out of your vehicle.
