Dell G15 issues

Hello, I just wanted to express my extreme disappointment with dell products. I bought my son a g15 for Christmas 2022. Here it is 6 months past warranty expiration, and the motherboard is shot. This is a $1000 laptop that I guess can use for a doorstop. I have been a customer with Dell for almost 30 years but will not purchase another. After reading threads online, this seems like a common issue. So my question is why do you continue to sell junk?
