Anyone observe odd ambient temperature readings on 2020.48.12.1?
Yesterday, 30F outside and cloudy, I noticed my 2019 Model 3D+ displaying an ambient temperature reading of 102F: imgur.com
After some time parked with climate running, it climbed to 103F, then went down to 90F. A reboot and power off did not change the reading, so I let the car sleep.
After sleeping for a few hours (still ca. 30F outside), the car showed a much more realistic reading of 42F. However, shortly after I got in, the temperature started climbing, a degree every couple of seconds. After 5 minutes, the car was showing an ambient temperature reading of 85F. I went for a drive at highway speed and it gradually dropped to 38F and then fluctuated between 38 and 40F for the next hour. Will take it for another drive today and see if it recurs.
I realize this is possibly a hardware problem and not necessarily related to the update. However, since my nearest SC is a couple hours away and mobile service doesn't appear as an option for any appointment category at the moment, I wanted to see if this may be affecting other cars. Cursory research pulled up some threads about a blank reading due to rodent damage to the front wiring harness, but nothing on severely inflated readings. The ambient temperature sensor attached to the active grille assembly looks clear of salt and debris, the front wiring harness is plugged in and doesn’t have any signs of damage. The only notable event yesterday was the update to .12.1.
Based on how fast the temperature readings climb when the car is first awoken and climate is enabled and then stabilize, it kinda feels like it’s displaying readings from a different temperature sensor that’s somewhere in the HVAC loop.
Hope this is not what Elon meant by the holiday update being :fire: :fire:
