NHTSA Complaint #11444939 — 2021 TESLA MODEL Y

With Tesla’s new software version 11.0 (Firmware 2021.44.25.2), the enabling of the front and rear window defogger is not readily accessible (they are buried in a menu). In the previous version of the software, there was a dedicated button on the screen to enable each of them. This is a safety issue because of the following scenario that happened to me today, comparing to my experience just the day before: I was driving in the mountains of Colorado, where it was below freezing and snowing. On the 22nd of December, BEFORE the software update, my front window started fogging up VERY quickly. I was able to turn on the front and back window defoggers with one tap. Today, I was driving back and the same thing happened — the window started fogging up. With the new software you had to tap twice, taking away your attention from the road in order to locate the defrost ON button. This is incredibly dangerous. I opted to move to the side and put my flashers on while I did that.
