There are definitely SSD issues, or more precisely SMC issues when rMBPs are fitted with Sandisk SSDs (as mine is).
It can cause the fans to randomly spin up to full speed despite the temperatures not being high and the cpu load being low.
BTW my display is LG and it's fine.
I seriously like this machine. It has one flaw that is annoying (the SMC issue causing the fan spikes) but it's fixable with a firmware update.
Maybe I'm lucky, I don't know but seriously I am very happy with my rMBP.
