Engine Clicking And Tapping Noises problems of the 2017 Kia Motor Sportage

I have a 2017 kia Sportage sx turbo my car has not run right ever since I leased it. There were times where it seemed like the car wasn't going to start, cranking, but not turning over. There are times when I hear a loud clicking noise when I accelerate, which sounds like something under the hood of my car is about to break. And then I started having issues with my spark plugs. The spark plug on cylinder 3 has burnt out and caused misfires in my engine 3 times now, starting as soon as 9,000 miles. Before, the dealership I went to blamed it on poor gasoline or too much oil in my vehicle and never fixed the issue after being at the dealership 3 different times because of the misfiring I was experiencing. The first time I went to summit place kia, they put me back into a faulty vehicle without fixing anything. My car then failed while driving on the freeway, misfiring and not properly accelerating. Luckily, I was able to get off the freeway safely and towed to another dealership that replaced the spark plugs. My car started misfiring again, and summit place kia replaced the cylinder 3 spark plug and blamed the issue on "too much oil. " now my car is at the dealership for the fourth time after failing again while driving, severely misfiring, causing the car not to accelerate properly or drive well at all while driving it. Kia motors, inc. And feldman kia in novi have decided to replace the short block of my engine, still not knowing exactly what is going on or causing the 3rd cylinder spark plug to burn out. I am not confident that simply replacing the short block will fix this, unless they know something that is not being disclosed to me. I feel that there is something inherently wrong with the design of the engine of this car, and this problem will affect thousands of others who have purchased this vehicle.
