NHTSA Complaint #11447106 — 2019 TESLA MODEL 3

Tesla implemented a software "update" 2021-12-24 and removed basic functions making driving in everchanging CA weather a hazard. Both Front and Rear defrost buttons were constantly across the bottom bar of the touchscreen in the car before the software update on 2021-12-24. After the software update, the functions have been removed from the ever-present bottom bar. Because the touchscreen is the only way to turn on the defrost, this is a hazard. Now istead of simply pressing a button on the bottom of the screen, you have to press the car, then go to "climate" then turn on defrost. This is now a 2 or 3 step process. The other way to turn on defrost is to "Swipe" up on the temperature, and this (if the climate control is off) will automatically turn ON the climate control. On the new screen, I then have to hit "climate off" and also "defrost on". This is unsafe. Standard functions such as: Volume, Temperature Control, Defrost should be a SINGLE PRESS away, not hidden behind several menus. Attachments Description: OLDUI.PNG this is the OLD User Interface. Notice bottom bar on bottom of "Screen" I have circled the defrost buttons in pink. NEWUI.PNG this is NEW User Interface. Notice the bottom bar now does not have the defrost buttons, but instead a "Toybox", Phone, and other icons that have nothing to do with driving a car.
