I'm holding on to my gas vehicle as long as I can because I really don't like the hybrid sad spaceship noise. I guess I could get it and disable the speaker but then that might void the warranty. The mechanic I go to tells me I can absolutely disable it and they will do it for me but they caution that it will void a warranty. I will continue to drive my old car until it falls apart.

> that might void the warranty

That would be explicitly illegal, it will definitely not void your warranty. It could hypothetically increase your liability if you are involved in an accident where you run over a pedestrian who argues that you were silent when you should have been making noise, but I am not sure this has ever been litigated.
