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.

The car shut off (engine died) when I was driving and it wouldnt restart. The car was in perfect working condition, low miles & well taken care of, no lights on the dash or anything. I had it towed to 2 different mechanics (first was private, 2nd was a Kia dealership) - they both told me I needed a new engine or I needed part of the engine fixed and told me it didn't fall under any of the recalls. From what I've read I feel like it is a manufacturer's defect due to all of the recalls on this model/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.

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.

This past winter (December 2022 ish), my car started ticking whenever I turned it on and the ticking never went away as the car warmed up. I took the vehicle to my mechanic who told me it was piston slap and that the issue was caused by a manufacturing defect in the piston and engine block sizing. I confirmed the issue myself with a borescope camera in April, and anyone who is able can view the damage as well. Since the issue is damaging a vital part of the engine, any time the car is driven puts all individuals in the car at risk. It has been confirmed by an independent mechanic, but has not been inspected by anyone outside of myself. The closest warning light I had came up over 2 years ago, but no warning lights or other symptoms appeared before the sound was audible around December 2022.

I have owned my 2012 Kia Forte EX since 2013 when I purchased used from a car dealership (not a kia dealer). I have kept all oil changes, filters up to date since purchase, plus in Pennsylvania we have annual car inspections, which my car has always passed. In early Jan 2023, I noticed a 'ticking sound' and was not related to low oil, leak, etc. The sound became increasingly loud and took to my mechanic. After he took off the engine cover and was able to put a camera down into the motor, the cylinders are bad. So, here I am with a 2012 Kia, mileage 83,836 and the motor is shot! I want Kia to replace my motor at no cost as I have read that Kia has agreed that all Kia's produced between 2011 through 2015 have engine failure. How do I have my engine replaced by Kia? I currently am without transportation,

On 10/31/20 my 2012 Kia Forte completely died at 49,000 miles while I was traveling at around 45 mph. I lost all power, the engine started smoking badly and I was stuck in the center of a 4 lane road with cars flying past me at around 50 mph. I had to call 911 because I could not get out of the smoking vehicle and I could not get the vehicle out of the middle of the road. The police officers had to do a pit maneuver to get me safely off to the side of the road. The vehicle was towed to the dealership where I originally purchased the vehicle in 9/2017. I was told after inspection that it had a severe knock sensor and catastrophic engine failure. My extended warranty company was charged for the $15000 engine that they replaced And I paid my $100 deductible. Although at the time the service department at Kia knew that this was an engine recall call situation that the manufacturer was responsible for, not my extended warranty company. My Kia forte Was in the shop for 2 months and the 1st engine they replaced did not work properly so they had to put another engine in during that period of time. Kia paid for the 2nd engine that was replaced. On January 27th of 2021 I received a notice from Kia Motors notifying me that my vehicle was part of the fire engine recall. I have had my vehicle in my possession a total of Maybe 380 days out of the last 438 since this happened. Kia corporate and the service parts Manager have been completely uncooperative, deceptive and negligent in their treatment towards me.I have gone through Maybe 25 loaner vehicles, had to bring the vehicle back 30 times, now a 4th engine is in the process of being replaced, I have defaulted on my car payments due to out of pocket expenses charged by Kia, the service department manager has stuck me with a $600 rental bill, a $250 traffic camera ticket, put me in a defective loaner that caused an accident and has now spent probably around 90k on a vehicle that is worth a fraction of that.
