Your LED's will go out whether they're "genuine" or knock-offs...
I don't know if the newer models are different but from what I read on here - someone correct me if I'm wrong - if you have the first version of the lights baking the headlights and taking them apart doesn't give you access to the area of light you need to work on to repair (I believe someone narrowed it down to the soldering points becoming dry and then the wires getting knocked around from day to day driving).
