1 Engine Knocking Noise problem

Failure Date: 02/23/2021

To whom it may concern: I took my 2012 kia Forte to a local dealership in shreveport, louisiana(orr kia) upon receiving a important safety recall by Kia Motors America, inc. Upon completion of my recall I was notified that the ticking/ knocking noise from the engine that has a odor smell to it was decline by techline because of a outside warranty. I'm not satisfied with this decision because the warranty clearly state vehicle's engine, engine noise, fuel smell, burning smell,etc. That may be related to an engine mechanical issue. At various times the engine light comes on and off.

About a week ago car was running fine except it would shut offf while driveing on occasion and throwing no codes so matt taylor kia could t figure out what to do with it. . The car has developed a very loud knocking noise ,putting off a very bad small and smok e out the exhaust,and recent oil change and we check the dip stick and oil is beyond low wich did not make any sense. The car has the 2. 4 engine wich sadly is not on the recall list despite many reports of the same symptoms that ultimately lead to engine fires.

4 Engine Knocking Noise problem

Failure Date: 09/01/2020

My 2012 kia Forte 2. 0l engine keeps making a ticking, knocking noise. Took it in for service and the dealer said that they could not locate the issue, but that I may just need an oil change. Oil was severely low, even though oil was just changed. There were no leaks identified. Also, my car has a jerking issue when accelerating. The car sometimes gets thrown forward without a check engine light being thrown. This especially happens on the interstate, or if the car has been driven for longer than 20 minutes. This is an extreme safety issue.

March of 2020 we bagan noticing a knocking noise coming from the motor upon cold starts which increases as the idle speed increases. Also makes the same knocking noise while engine is at running temperature. Upon further investigation it has been determined to be a connector rod or connector rod bearing issue. This is a known defect of the theta ii motor. Also around the same time the vehicle had the same problem as recall sc158 brake pedal stopper pad. We were informed that it was not a safety issue and had to pay out of pocket for the repair expense. The vehicle came out of park with engine off and keys not in ignition, almost causing collision when car rolled into street. Again, kia stated that was not a safety issue.

Driving when it stalled along with minor smoking from engine area on sevaeral occasions. I contacted my local kia to see if they may have insight as to what mihjt be the cause only to be told they would need to indspect car along with a hefty hourly fee. And within several days it stalled , the engine came on then died. I towed car home. It woul start and run for appr. 2 minuteswith a very loud knocking noise. I then had to have it towed to mechanic shop to have it checked to be told it was blown due to throwed rods and would need an engine replacement wgich I did have done. It was brought to my attention by the shop to the issues kia had had and was having with the theta engine as thats what my car had.

11 Engine Knocking Noise problem

Failure Date: 03/15/2019

Driving down an interstate around 75mph the engine started making an abnormal loud engine knocking noise so I pulled over to the median and the oil light came on, engine seized, and the car died and would not start. Car had oil. Towed 100+ miles to our local kia dealership and they said #2 rod bearing "severely worn and causing the engine to make noise and stop rotating". They recommended a complete engine replacement at a cost of around $5700 (cost and labor). 2012 kia Forte sx with 2. 4l engine and 106,xxx miles (6,000 outside their 10year/100,000 mile warranty). Car had regular oil changes at the proper times. This is the same type of problem (worn rod bearings) kia/Hyundai had with their other engines which required a recall to address the thousands of grievances. I would like these 2. 4l Forte engines to also be included in a future recall because I believe these engines are either defective in their manufacturing process or just faulty by design. Had I not pulled over when I did there is a possibility the engine would have seized while I was driving interstate speed with the typical interstate traffic (semi trucks all over) with my wife and two small children on board. Kia refuses to acknowledge a problem and so far have offered no satisfaction. A modern car should last more than 7 years, unless it was designed wrong or damaged in the manufacturing process.

15 Engine Knocking Noise problem

Failure Date: 03/23/2017

. I was driving on the freeway on my way to work going about 65 mph when I started a hearing a knocking sounds. At first it wasnt that loud I only had a few miles to get to work so I thought I could make it but then the sound got really loud. I pulled of the freeway and parked it at a friends house and he took me to work. So I go back the next day to try to figure out what was wrong with it I checked the oil to see if it was low it was ok. I had just done a oil change about 2 weeks before I tried to turn it on but the car wouldn't​ crank at all. I had it towed to a shop and the mechanic looked at it and told me that I would a new engine. This is a 2012 kia Forte with around 80xxx miles on it and now it needs a new engine. I have a 2001 Ford focus with 190*** miles on it and the only thing I've had to fix on it was the clutch the went out 2 years ago. I'm still paying this car off and I can't even drive it. I'm looking around online and this seems to be a common problem, people just driving and then they hear a knocking sound and then the engine goes out. I took really good care of this car I went above and beyond to make sure that this car would last long yet it didn't​ matter. Even finding a good engine is hard to do so and expensive when I thought I had one the seller took it apart to see if the engine is worthy of selling it with his warranty promise. He gave me back my money because the engine I bought from him was no good and he didn't want to sell me a a possible faulty engine.

Started with a knocking sound in the engine. Engine light came up and car started to lose speed. The engine seized and my mechanic told me that the car needed a new engine as it was not repairable. The Forte is not on the list of recalls but it has the same engine issues as the ones listed under the recall. I am still paying for this car that is 5 years old!!.
