Holiday software killed FSD!

[Spartan_117]

I am not 100% sure if the update came from the KC Service Center or from Tesla but the Current Software is 2025.44.25.5. Current FSD Software is v14.2.1.25. Everything is working fine so far.

I know this is not critical but the Toy Box Santa Mode "Spread Cheer" does not work

FSD stopped working on my Foundation series Beast after the Holiday update. Matter of fact it stopped working after the previous update

Had to clear the camera calibration, reset the DAS, drive on the highway 30 miles and let it sit overnight. It worked the next morning. This is frustrating!

After my shop visit my rep called saying it might take a few updates to get implemented in software but in the meantime the disconnection of the front light bar fixed my FSD.

I installed the Holiday software last night, and I drove my CT today using FSD. Everything seemed to be working fine. Fingers crossed.

Drove 1,000 miles 97% FSD day of update. Worked perfect.

Do you suggest holding off? I have it scheduled to install tonight at 2am.

I haven’t had any issues with the update. In fact, FSD seems to run much better.

Same issue for me: after the Holiday update, FSD stopped working.

Data point: I have an S92 mirror installed, powered from the left footwell.

Symptoms: I realized that the FSD visualization does not show anything. 2 button reset did not fix the issue. I checked the camera views in the service menu (not service mode) and all of them worked fine except the driver side repeater, but it showed the picture when I was backing up, so it must have been just a software glitch.

What fixed the issue was getting into service mode and reset camera calibration. After exiting service mode I immediate got back the visualization of the environment and after driving a few miles I got back FSD, too.

No issues since then.

After loading the holiday software update my FSD no longer works despite reboots and power off and dr8ving and I have tried button on steering wheel and tapping screen and nothing makes FSD engage. I checked in menu and FSD is selected. Anyone else had this happen?

I have no trouble on my Cybertruck. 14.2.2.2

The first drive after the holiday update FSD would not engage with a message on the display saying poor GPS signal. Only took about 15 seconds of driving then it engaged without issue.

I did have a brief error message, but it cleared up right away. FSD 14.2.2

New updates have fixed all my issues

I am out of the country and cannot check whether or not the recent updates fixed the issue with the wiring harness for the front light bar interfering with the occupant radar or seat sensor that was disabling FSD. I still have the harness removed.

It addresses the issue. I still have the harness installed.

Agreed, I reconnected the harness and now my front bumper light bar works again as does FSD.
