Non of these Tesla accidents that you have documented occurred during a solar wind or geomagnetic activity strong enough to have ( CME ) caused coronal mass ejection that would have caused any form of single event upsets or soft errors.
Please cross reference your accident list with this website that clearly shows solar wind activity is too low to cause any soft errors. https://www.spaceweather.com
In order for solar winds to cause a single event upsets the speed needs to be at a velocity of 750 km/s and above with a temperature of 800 MK. Nearly matching the composition of the Sun's photosphere.
There for your theory of SUA in Tesla caused by solar winds and geomagnetic unrest is not possible. More importantly scientifically impossible
