software wont brick the phone, especially software thats made for the nexus 5. and google will still replace a phone if its the hardwares issue, even if you are rooted running custom software. that risk that you say everyone should be aware of doesnt really exist if its the hardwares issue. and if its software, it can always be fixed.
That's not entirely true. My One X had to be JTAG'd because of software. Granted it was different circumstances than this, but it certainly wasn't a hardware fault.
If it is a hardware issue then yes, it will still be covered by warranty, but running any type of custom firmware does come with a risk, Nexus phone or not. As it stands, OP doesn't know what the problem is, so calling the seller and demanding a replacement isn't quite appropriate. That's all I was really commenting on.
