Kia Sorento Engine Misfire Due to Faulty Ignition Coil

(25 reports)

An engine misfire may develop due to a failed ignition coil. Our technicians tell us one coil is used for each cylinder. If one fails, often times another is not far behind. It may be worth considering replacing all the coils if a failure is encountered.

My Sorento has been driving a little rough, this morning when I turned the car on it was shaking a bit, when I started to drive the check engine light would come on whenever my foot was on the gas. Brought it to my mechanic, he told me one of my ignition coils were bad and the other 2 were on their way out soon. Replaced the bad one today ($300), next week replacing the other 2 ($600). -
Rough idle, hesitation on acceleration. Autozone shows mis-fire on #4 cylinder. -
This is the second time I have had the problem. No warning, the engine starts to run rough then the engine light comes on. -
breakup at acceleration, replaced all three coils on left side of engine, running fine now! -

my car has been misfire and the ocde came up for ingnition coil -
Engine idling rough at very low idle. Clears up in colder weather, worse in warmer weather. Check engine light didn't go on at first, and mechanics couldn't figure it out. When engine light came on, code indicated ignition coil failure. Tested to be sure that is what it was by switching out coil, and verified which coil was out. Replaced it and problem returned shortly. Another coil out. Mechanics say they will replace only when they fail .. no need to replace them before they fail because it wont leave me stranded and they can get it done in a couple of hours while I am at work. Love my mechanics, and love my Kia! -
Coils burn up still in shop -
The engine check light became on. After checking with autozone, it came out to be misfire in two or three cylinders. -
