I dont know of any but I dont necesarily see them both being the same brand as being a problem, its unlikely they will both fail at the same time even if they are the same brand. unless you did something like a firmware update on both at the same time and the firmware had an issue, but in that case i wouldnt do them both at the same time anyways
In terms of safety its very likely that they fail on the same time since everything is the same (hardware, software etc.).
But I probably found now one from mtk...
