The ignition coils actually have no estimated lifespan. It widely ranges on regional weather and vehicle use. Humid weather can drasticaly shorten the life of the coils. Also, vehicles that are used in short city trips can also fails sooner. Then constant heating and cooling can lead to a crack sooner than a highway driven vehicle. One thing we do know for sure is when the ignition coils are old, and one fails, it's best to replace all of the coils at the same time. This is because when one ignition coil fails, it's likely that the others are not far behind. You can use an OBDII scanner to find out if you have a failed ignition coil. You will see error codes such as:

 

 

 

P0301 (Cyl# 1)
P0302 (Cyl# 2)
P0303 (Cyl# 3)
P0304 (Cyl# 4)
P0305 (Cyl# 5)
P0306 (Cyl# 6)
P0307 (Cyl# 7)
P0308 (Cyl# 8)

 

Using these codes, you can locate the bad ignition coil, and we recommend to swap it to another cylinder and re-scan. If the misfire code follows the ignition coil, then you know for sure you have a bad coil pack. If the code stays on the same cylinder, then it's likely that there is another issue such as a fuel injector, spark plug or other sensor or engine issues). Replacing these is quite a straight forward procclless. While it may take some time, it isn't a difficult job to do. Check out our how to section to find out how to replace the coils in this vehicle. A misfiring engine feels like the engine is shaking and short of power while accelerating, and when reaching a crusing speed, the engine runs normal.
