Back in July my car started jerking, stalling, and smoking. There was a recall 20v750 open for engine fires. The dealership check it out and said everything looked good. They installed a knock sensor related to the problem. Last week my car did it again leaving me stalled on the interstate at night. There is now a P1326 code for the knock sensor which confirms that there was a issue. However I'm being told that due to my mileage the warranty had expired and there isn't anything they can do.

The engine started knocking just like all the other fortes and theta engines that blew up or gained the same knocking metal to metal noise. I have since found metal shavings in the oil which tells me that my engine is on its way out the door just like the rest that had this same problem. My engine needs to be recalled and replaced alongside the rest! Kia needs to own up to there engineering mistakes and install a new engine. My car should not be ignored on that recall seeing as it has the same engine as all the other fortes that were given new replacement engines. I refuse to be ignored on this matter and will not put forth my own money to fix something Kia is liable for. Kia is putting my life and others lives in danger. When will they take actions and responsibility for the rest of the Kia’s out there with the same engine symptom. I also haven’t got a recall for a knock sensor upgrade. I refuse to be without a vehicle because of Kia’s terrible engineering and poor production and assembly of these cars. I should not be experiencing an engine rod knock at 100k miles that has only become louder with time. I will be presenting the car to Kia for other recalls to be done and will be complaining about the other issues. Thousands of people have had to pay out of pocket to get a new motor. That’s on Kia to make things right with there customers for selling them a faulty product.
I own a 2012 Kia Forte . My engine started knocking, ticking sound. A mechanic used a mechanics stethoscope and the cylinder is collapsed, bad lifter. I always keep the oil changed regularly since the day I purchased. This is the same problem reported by thousands of Kia owners. I expect Kia to cover a new engine as I know a lawsuit was filed for the same year and model that I have and they covered the replacement of engines.

I saw that 2012-2015 kia fortes had a recall for engines but mine was not a part of it. My car had a ticking/knocking sound and I took it to the mechanic and he said that I needed a new engine, he said the knocking could have started because of low oil which is impossible because I have kept up on my oil changes. So now I don’t have a car, it’s almost $5000 to fix my engine. I would like kia to fix my car
UNKNOWN: 04/11/23 I purchased (as second owner) a 2012 Kia Forte (less than 2 months ago) only had 107,799 miles. Purchased as a Senior Citizen for doctor appointmenta & food shopping....after a short while I noticed a tap/knock from the engine that has gotten louder with every ride....Took the vehicle to Dealer Matt Blatt Kia in Egg Harbor Township for diagnostics. Couldn't believe I was charged $190.82 to receive a paper telling me it has a "knock" which I knew & took it there for & that it NEEDS A NEW ENGINE! The car fax a Kia lady printed out for me, shows vehicle was maintained wonderfully....from the info I've located those engines are bad so the KNOCK, KNOCK, KNOCK that's grown louder would be engine replaced? Can you assist me I purchased a vehicle that now can BLOW UP! Thank You for your time.
Engine described as making a knocking sound and having total engine failure. The car is not covered under the current 2020 Kia engine recall as it is a 2.0 litre engine. It has been inspected by Kia and an independent auto shop. It was not eligible to receive the software upgrade which would register the knock engine failure. No warning signs appeared beforehand besides a knocking sound which started a week or so before I took it in. This engine could have failed while I was driving and caused an accident. This is a common problem across Kia’s that Kia knows about and this should have been covered by them since they manufactured a faulty engine.
While driving on the highway I had the Check Engine light come on. After approximately 5 minutes, while accelerating, all the system lights flashed, and then turned off. The engine stalled and the vehicle was coasting. I pulled the vehicle to the side of the road, and though the vehicle had power, the engine would not start. I towed the vehicle to a mechanic who told me the engine could not be salvaged or repaired. As a replacement engine would cost as much as the vehicle is worth, I am now seeking to sell the car to a junkyard or other interested party. I believe this vehicle's Theta II engine's design is what led to its failure. However, Kia's SC200 recall campaign only covers 2012 Kia Forte's with a 2.4-liter MPI engine, and my vehicle has a 2.0-liter MPI engine. After spending 2 hours with Kia on the phone, they told me I had no recourse with them.
