Chronic Chest Cracks On My Kia Cee'd 2012 Model Car

I bought my Kia Cee'd 2012 model (2012-2017 body) vehicle as a second hand vehicle in the 2021/January period. Although I protected the chest area from the sun and kept it in a closed garage, which was not a problem when I first bought the vehicle, as it turns 10 years old as of 2022, cracks began to form and become more visible on a regular basis, as can be seen in the attached image. I didn't pay much attention at first, but as I researched later, I learned that Kia vehicles from 2012-2013 had chronic problems in general after they turned 10 years old. At the service I went to with the thought of airbag damage, it was recommended that nothing could be done to the cracks and that I should have them covered with artificial leather. I need authorized service support regarding this chronic problem. Finger-sized cracks reached gigantic sizes day by day. I request that my problem be resolved because my vehicle has become suspicious (accident, defective) and has lost value.
