> "This leads to widespread failures in the car, typically putting it into limp mode and disabling many features controlled via the touchscreen." eMMC failure does not put the car in "limp mode". It does disable the touchscreen, making things like the air conditioning controls and backup camera unavailable (in older software versions). "Limp mode" is when you have severe power restrictions due to very low battery charge, or some other major powertrain fault in an EV. Sometimes called "turtle mode" because a turtle icon will appear on the instrument cluster.
