Oh, so an actual reset button like on a PC! Its existence alone is admitting that the firmware is shit. An embedded system should never freeze.
But admittedly, most car infotainment systems freeze/crash occasionally nowadays. Mine as well but it went with the Microsoft BSOD "solution" and restarts automatically.
Yeah, most infotainment systems hide their memory leaks behind the fact that when you turn the car off, you reset the computer. Not so in an always on EV.
My $200 Chinese android system doesn't.
So I'll push back and state that infotainment systems aren't embedded systems, more akin to a phone OS with the wide array of UX applications.
But yeah these infotainment systems are often left running on newer cars for connectivity and other features and just like any other OS, leaving it up and running is going to slow and get unstable over time for to memory usage.
Like I said, mostly not a big deal unless you're a Tesla and critical information is there and you didn't regression test properly.
