My laptop y510p has an issue for the third time and i need a replacement

Question

my y510p laptop got an issue for three times and i need a replacement
i bought it in april/2014 and more than 2 and half months wasted for maintenance.
first time:
after few weeks i got problem with screen colors and i sent the laptop and the problem was in the motherboard and they replaced it.
second time:
i got it from maintenance center with 2 issues:
1- camera wasn't working
2- suddenlly  freeze from time to time , sometime a blue screen appear after ,  i need to turnoff laptop from the power button to work again and it takes so long to open after that.
i sent the laptop again.
note: maintenance center claims that there wasn't any issue and even the camera that they told me that they fixed it they didn't wirte it in report. that's what i figured out when i talked with lenovo customer services
third time:
suddenly freeze from time to time again when i tried to enter bios immediatly after freeze happen i found that 
harddisk wasn't  appearing.
so i sent it again and i asked for replacement
maintenance replied that it's a motherboard and hardisk issues.
stayed there for 45 days and i called them for like 7 times to know what is the reply on my request and every time they ask me to wait more.
today i called them and they told me that the request of replacement is refused ...!
and they told me to post a message here if i insist on replacement.
laptop serial no:xxxxxxxxx

It´s crazy how many people have the same kind of problems with this computer.. and what´s even worse is that it seems that the only option is to send it to Lenovo for a motherboard replacement. I have the same problem (mainboard dead) but unluckily for me, my y510p is out of warranty (I only used it for like 4-5 months then it was stored while I was away). Everyday I get on the internet to look for a motherboard replacement myself but I just can´t find any.. Why is that? 
Also, this is a "new" computer, if I´m not wrong it was released around the end of 2013. How is it that they already discontinued it? Do they usually discontinue their products that fast? Or is it perhaps all these Y510P computers had problems from production? How can someone spend over a thousand dollars, use the computer for a few months (normal use, not even gaming..) and one day is dead and the motherboard needs replacement?? Why nobody really complains about this? I really don´t know what to do as that were all my money. I really just want to get rid of this crap and never ever buy Lenovo again and never ever recommend it to anyone. I don´t even feel secure spending the money on a motherboard replacement because it seems to me that the problem will come back. Because as I said this seems to be a problem in their production of this particular model. Again, over a thousand dollars computer and its quality is worst than the cheapest ones.. shame on Lenovo.
