Front and rear park sensors/warning beeps and lane departure warning stopped working

[BreatheEasier]

While on a trip yesterday, I received a warning that the lane departure warning was unavailable, and would return on the next drive. Well, I've let the car go into a deep sleep overnight, performed a reboot twice, and no change - the lane departure warning, parking sensors, and parking sensor beeps have all stopped working. No errors being shown on the display since the drive yesterday. I haven't performed a firmware update in about a week or so...I'm on 2022.4.5.3. Anyone else experiencing this issue?

If the 12V battery has one of six bad cells (resulting in a voltage reading much lower than 12.0V) that can cause multiple sensor issues. At 2 years of age for the Model Y I would have the 12V battery checked.

Interesting, will check out the 12V battery. I'm getting some strange behavior now. The rear parking sensors work intermittently, and sometimes so does the lane-departure warning. Still nothing at all from the front sensors. I'll be making an SC appointment...
