Well I'm speaking from experience after using them from 2006 to 2018 vs the Bosch unit. I've installed plenty into friends LR's, customers, and my own (when I bought a D2 with a Bosch unit and got a P0441 fault shortly after owning it). Any piece of hardware can and will always fail that's just how it goes, but I have yet to have a single LR come back to me with a dead Hyundai unit in it. It's always a Bosch or cheap Dorman unit that has failed.
