1 Engine Knocking Noise problem

Failure Date: 11/02/2020

The vehicle mileage is currently at 115,446 . At approximately 110,000 miles vehicle started with a very loud cold start. Not only was it loud but it was rough with a high rpm. I know they call it cold start for a reason but this is not common with other vehicles I owned that were 2015s. Now the vehicle started making a ticking or knocking noise. Currently this is my only vehicle and with the other complaints that are matching exactly up to mine why isnt this problem being investigated or recalled? if and when this vehicle seizes on me like every complaint on here I will update. There is supposedly a class action lawsuit for this year make and model but not a single recall. Not even an investigation? please update us and previous owners of the complaints what steps yall are taking to fix this problem.

4 Engine Knocking Noise problem

Hello. My name is kodaah hansen. I drive a 2015 kia Forte5. It's the sx model with right around 91000 miles right now; and as of recently it has fallen ill. I took it to the dealership after I noticed a slight knocking sound as well as some weird misfires I was feeling. After diagnosis they told me and I quote "internal damage to the cylinder head&possibly pistons from what the technician gathers so far. A tear down to visually inspect is the next step. For the diagnosis though the cost is $134. 98". Based on the information received from them I contacted the warrenty company, expecting them to cover the costs but for some reason was turned away. I am now coming aware that the issues listed above have been subject to many recalls for the exact same engine as mine, however I learned this information though a third party technician. Not once did the dealership mention it. I looked further and found several cases on many online kia forums of people claiming to have the same issues with the same engine. I am just looking to have some help getting this situation resolved as I've had many people tell me that I shouldn't be having these kinds of problems with a car this young. Not to mention that my car still falls under the power train warrenty as well as the extended warrenty. Below I have sent copies of all the diagnostic information I received. Please respond as soon as possible. I thank you for your time.

5 Engine Knocking Noise problem

Failure Date: 03/14/2019

The engine began, without warning, consuming the oil. The engine then began making a knocking noise that is now irreparable without replacement. This knocking noise, due to low oil, was not preceded by the "oil light," as I had recently received an oil change. The car now struggles to accelerate and I have to add oil every 2 weeks or so. This is a similar issue with other kia models, with the same engine, that will be involved in a class action lawsuit in January 2021.
