I wish I understood more about cars. I don’t know what I’m looking at.

This is the heart of the car - the engine. In the photo there is a cylinder and a piston.
As you can see and understand, scratches / scuffs on one side are not normal. The cylinder wall should be polished like a mirror.
The Koreans already had a recal-company in America and Canada in 2016, about 150k cars with 2 and 2.4 engines.
Why did it happen?
Engineering miscalculation. Aluminum block, short piston stroke, the piston had a short skirt, thin oil lines.
And as a result - Overheating, not lubricated enough, the piston was not cooled properly.
Hyundai / Kia engines began to work loudly and consume oil already from 20K km, as scuffs / scratches appeared in the cylinders. It also caused engine damage.
Kia / Hyundai seems to have solved all the problems, modernized the engines and everything seems to be fine, but already in 2018 a lawsuit was filed in America against Kia / Hyundai. In the US, car owners Hyundai and Kia blame Korean manufacturers for factory defects, which can lead to severe engine damage and, in some cases, spontaneous combustion. Miscalculation again?
And the most interesting thing is that the lawsuit among the list of motors was registered: Lambda II 3.3-l and
Lambda II 3.3-l T-GDI (remember the models).
Could this happen with telluride?
Yes, there is a chance, since the engine is new.
That is why I asked you about the edoscope.
As an engine (aircraft) engineer, I would be very interested to look inside.
Why can this happen in Telluride?
We receive a car with a new heart - the 3.8 L Lambda II V6 GDi. This motor was specially designed for telluride and paliside based on the Lambda II 3.3-l T-GDI motor, which was featured in the lawsuit in 2018.
PS: In my 2017 sedona, I drove from 0 to 35K km.
Having changed it to the 2019 sedona, today I have already covered 30K km. Both are powered by a Lambda II 3.3-l T-GDI engine.
I noticed changes in performance on both cars:
After 10k-15k, when the engine is cold, it works very loudly, like a tractor. It is worth warming up, the sound decreases significantly.
Doesn't eat oil at all. I change every 6k, from replacement to replacement is normal, without topping up.
