I heard a knock coming from the engine and suddenly the car died while driving in the city the check engine light came on and would not start up again but the power was still on for lights, etc. I had to have it towed to the repair shop. I was told the engine is shot. After researching the kia forte I found a lot of reviews complaining of the same thing on the 2012 forte. Now with the recalls for the other kia engines with the same or similar engine types, this make and model needs to be included!!!

While driving, engine made a sound like a ticking noise then just blew. Oil all over the engine bay and ground. A lot of smoke coming from under the hood. Would not start or do anything. Glad it didn't catch fire with all the oil everywhere. Had to have it towed. Took it to mechanic, come to find out the engine had seized up. This happen while driving on highway. Speed limit 70. It was like the engine went boom. Glad I was in the right lane to be able to get the car over to the side. Lost all power and unable to control car. Mechanic had to order and waiting on used engine coming from california to put into car. Will cost 4000.00 for this repair. Still owe on this car too.

While driving this car, I heard a knock coming from the engine!! I had it towed to a kia dealer and was told that I needed a new engine! This is unacceptable for car that is only 6 years old and all maintenance kept up to date!! I did some checking and other kia engines with similar or same engine types have been recalled. This make and model needs to included!!

On 7/23/2016(milage 108000) I was driving my 2012 kia forte sx koup to work traveling 70 MPH on the highway. 2 miles from work I began to hear a loud knocking sound . Arriving at work I did a quick engine inspection but could not find anything visually wrong (leaks, smoke, loose parts) later that morning I returned to my car to test the engine and could hear the same noise. I decided it would be best to have it towed to a mechanic. Vehicle was not inspected until 07/25/16. Mechanic said the engine needed to be replaced after discovering a bad rod. Mechanic also contacted kia to see if by chance they would offer and extended warranty, but kia would not repair engine since it had passed the 100000 mile warranty. (just 8000 miles over warranty !!!!!!) my wife and I decided to bite the bullet and have the engine repaired. $4300 and one week later my vehicle was returned to me. I now see all of these news stories about kia catching fire and other horror stories on the federal safety agency website about the same experience others have gone through . I am even more outraged that it could still happen to me and the fact that there is a current recall for the airbags and seat belts but not the engine!!!!!!!!!!! Please do something!!!!!!

I am the original owner of a 2012 kia forte koup sx with the 2.4 liter theta ii engine that is being recalled on a limited basis by kia under the federal safety agency sc147. A week while merging with faster traffic my engine died forcing me into a very dangerous situation trying to cross several lanes of much faster moving traffic with a dead engine. I came to a stop in the center lane and had several very close calls before other vehicles had to swerve at the last second to avoid hitting me. Much like the countless other examples of vehicles equipped with the theta ii engine seizing or spinning rod bearings my engine seized solid even though I meticously followed the prescribed maintenance intervals kia suggests. After doing a little research I was dismayed to see how wide spread this issue is and cannot fathom why kia is permitted to only recall some vehicles with this same engine and not others. I very strenuously urge the federal safety agency to expand upon recall sc147 to include all vehicles with this engine before other injuries or deaths occur as I could have very easily sustained. There should be no excuse and no defending of kia's position that this engine only fails due to manufacturing flaws on some models and not others models when they both use the same engine when all one must do is to do a quick google search to see countless examples of american consumers being left without assistance to face the manufacturer to get these issues resolved. It is yet to be seen if kia appropriately make all necessary repairs to my vehicle either under the 10 year/100,000 mile limited warranty (my vehicle is 6 years old with 80,000 miles) or under recall sc147; however, based upon what I repeatedly am finding, kia will try denying repairs, demanding all maintenance receipts and generally making it as difficult as possible for consumers to get warranty work done.

Rod bearing failure on a 2012 kia forte koup 2.4l engine at approx. 93,300 miles with no prior issues. Engine was properly maintained and never abused. Began rattling while driving normally on the freeway and was subsequently determined to be the #2 piston hitting the head. No prior indication of anything wrong, no unusual engine noise, no "idiot" lights, no misfire, no vibration, nothing, just a sudden pulsing noise that was first thought to be the exhaust sound from a passing harley.

Bought my car used from a dealership and am the second owner. Car only had 36k miles when purchased. The dealership also sold me a bogus warranty for $2,995.00 for 36 months 60k miles when the manufacture warranty gave me 5 years/60k. While driving down the road this knocking started in the engine and it was loud so I pulled off the side of the road had it towed home. After a few phone calls I had it towed to a kia dealership who said there was a problem with the bottom of the engine and it would need a new engine. I'm pretty pissed about this situation because kia and the dealership want to take no ownership for this vehicle despite all the reports I've read on line about people having the same problem. My car has 84k on it now but faithful oil changes have been done since I've owned the car. Of course it's out of warranty as that ended at 60k. There is a recall for the exact same engine in other kia cars but not this one and I wish I knew why. Mine has a theta ii - 2.4l dual overhead cam with a dohc engine and the recalls are for a the exact same engine except it's called a gdi engine. What the heck is the difference if they all keep blowing - it's the exact same [xxx]engine. Bottom line is that I still owe approximately 12k on the [xxx] car - no one wants to fix it at no cost to me and it could cost me around 8k to fix it. Ridiculous to keep paying for a car you can't afford to fix and or drive. Something needs to be done about this problem. Good luck to all kia owners out there - I will never buy another one.
