Hello, when one ignition coil fails it is generally recommended to replace all coils at the same time. When one coil starts to fail or fails it increases resistance in the whole ignition system. It is not uncommon for multiple others to fail after one fails. A certified mechanic, such as one from YourMechanic, can diagnose your ignition system and replace any ignition coils as necessary.
