I've also seen a fair share with a failing third brake light, about half of the LEDs not lighting up. Probably isn't noticed by the driver until regular service, government inspection, etc. It's not a surprise that many things fail on a complex assembly with all new parts. No wonder automakers do their best to share small stuff like buttons, latches, door handles etc. between many makes and models.
