I've noticed recently that several functions from the "Controls" menu in the phone app aren't working:
  • Front (frunk) -- no response (but the app appears to take the input, including the "are you sure?" message)
  • Trunk -- no response (but the app appears to take the input)
  • Start -- the weirdest one: the app takes the input, gives the "are you sure?" message, and starts the 2:00 timer; meanwhile, the car shows the timer with the "started by app" message... but the car ignores any attempts to turn it "on" (shift out of park)--instead, it gives the "key not in vehicle" error. After 2:00 minutes, the timer expires normally.
  • Honk -- normal (horn honks)
  • Flash -- normal (headlights flash)
  • HomeLink -- normal (garage opens/closes, "are you sure?" message appears)
  • Vent -- normal (windows open ~1" or so, "are you sure?" message appears)
  • Lock / Unlock:
    • Lock -- normal (doors lock, lights flash as if keyfob used)
    • Unlock -- no response (but the app takes the input & gives the "are you sure?" message)

Car is a 2020 MSLR+ running 2021.4.12; phone is an iPhone 8 running iOS 14.4.2; Tesla app is ver. 3.10.10. I've tested & used all of these functions in the past, all worked as expected.

EDIT: I should've mentioned, I've done multiple reboots of the phone & the car, no change....


Any ideas??

Try doing a power off reset. Instructions from the manual:

If your vehicle demonstrates unusual behavior or a nondescript alert is present, you can try power cycling the vehicle to potentially resolve the issue.

1. Shift into Park.
2. On the touchscreen, touch Controls > Safety & Security > Power Off.
3. Wait for at least two minutes without interacting with the vehicle. Do not open the doors, touch the brake pedal, touch the touchscreen, etc.
4. After two minutes have passed, press the brake pedal or open the door to wake the vehicle.

Verify that valet mode isn't enabled. Following that, put in a support ticket to Tesla through the app. This isn't going to be end user addressable.

Nope, not in valet mode. I had looked at that (was never on, I've never used it). Based on your post, I enabled & disable valet mode a couple of times--no change. Good idea, but not the solution this time. Thanks!

Will send in a ticket....
