Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils.

How do you stop ignition coils from failing?
Keeping your spark plug in optimum condition can reduce your chances of experiencing an ignition coil failure. As spark plugs wear down, the gap in each spark plug is fired is widened meaning the coil needs to provide a higher voltage in order to bridge the gap.
Can all ignition coils go bad?
Most ignition coils are durable components, but they are neither indestructible nor designed to last forever. Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle's fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely.
Is upgrading ignition coils worth it?
Whether working with coil packs or traditional canister style coils, the advantage of an upgraded coil makes for a hotter spark. Intensifying the heat makes it easier to burn the fuel and air mixture. This translates to improved performance.
What Makes Coil-On-Plug Modules Go Bad? (Ignition Coil Diagnostics)
How often do ignition coils go bad?
The ignition coil on car is supposed to last around 100,000 miles or more. You will have reduced gas mileage when coil begins to go bad and becomes less able to transfer power. Your car requires more fuel to run, this means you will spend more money on gas than normal.
How many years do ignition coils last?
Average lifetime of ignition coil is around 100,000 miles or more. It is not an easy worn out replacement car part but still could fail for variety of reasons.
Why do my ignition coils keep failing?
The overheating of ignition coils can hinder their ability to conduct electricity. Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat.

Do ignition coils affect performance?
The purpose of an ignition coil is to convert the low current from a car battery into enough power to ignite the fuel and start the engine. When there is a problem with an ignition coil, it will cause a range of mechanical and performance issues.
How often do ignition coils need to be replaced?
While ignition coils do not have a service interval, they do have a lifespan. There is no specific mileage or age to replace them. They should only be replaced when they are bad. If you notice any cracks on the plastic or epoxy, and of course misfires, then it is time to replace the ignition coils.
Ford Flex Ignition Coil Keeps Melting Or Swelling Up. Missfire Bad Ignition Coil Cause And Fix
Can spark plugs cause coil failure?
If the spark plugs are worn out, it forces ignition coils to operate at a much higher output. Keeping your spark plug in optimum condition can reduce your chances of experiencing an ignition coil failure.
Should I replace all ignition coils or just the bad one?
In cases like this, your mechanic may recommend replacing all three rear ignition coils as a preventative measure. Whenever one of the ignition coils fails, it's also recommended replacing all spark plugs if they haven't been replaced in a while. New spark plugs will help ignition coils last longer.
