ECUs aren't perfect. On my old 2003 Volvo a common problem was solder points in the instruments panel failing after 8 to 10 years, and for the central ECU the connectors could corrode due to moisture. Luckily I wasn't affected by either. Of course Bosch probably doesn't perform "disruptive" software fuck-ups such as Tesla did here, and if they do, chances are good out-of-warranty replacements are free or at least come at a reduced price. (But at least an EV doesn't have issues like VWs "maintenance free timing chain" skipping a link or two after 70kkm/50kmi)
