aftermarket parts only effect the warranty in that they aren't covered themselves and if they impact factory parts those parts may not be covered because of the changed condition. There isn't really much these could impact, they aren't really effecting the seat performance in any way that could strain a seat motor or anything like that. If the dealer breaks something while installing them, that should be on them and is totally separate than a warranty issue.
if you get the heated seat option you might want to make sure its an actual shop that knows how to wire accessories and not some random upholstery guy or something, but any dealership or competent shop will know how to wire them so that it won't impact anything.
