2022 Model S loss of driving controls

[lt2010359]

I've seen a few similar posts to my issue but nothing exact so I thought I would post it. My 2022 long range S sometimes loses autocontrols. I get the following errors:

• Steering Assist Reduced (followed by power steering being disabled mid-drive)
• Park Assist Unavailable
• Lane Departure Avoidance features unavailable
• Regenerative braking temporarily reduced
• Automatic Emergency Braking reduced
• Stability control disabled
• Traction control disabled

I notice this mostly after switching into reverse. (Although not always. sometimes it happens in Drive) I fixed it last time by finishing my reversing, getting out, letting the car lock, then re-entering the car so that it gets a fresh start and going into drive. Then magically everything came back. If I do not do this maneuver the car will stay in manual mode. I have tried a hard reset, had a software update, checked the cameras, etc. No obvious reason it is happening. Thankfully it has never happened mid-drive. It only occurs at the start of a drive and then lasts the entire drive. If I start a drive and am on the freeway or main roads then it is all fine. Only seems to happen on initial start or ending a drive. eg. Backing into a parking stall or pulling out of a parking stall.

Anyone else having this issue?

I've seen that happen at low speeds if you step on both the accelerator and the brakes at the same time. (I used to do that to dry the rotors a bit before parking or clean off corrosion). You also do get a warning about both pedals being pressed.

Maybe you should schedule service to rule out a hardware issue.

Same here, except instead of “steering assist reduced”, I have “cruise control disabled”.
MX 2017 with HW3/MCU2 upgrades.
Tesla service scheduled for July 18, 2022.
I plan to report what Tesla discovers.
Lt2010359 is yours fixed? How? Thanks!

Software bugs. I feel that the engineers are pushed really hard and quality control of the software is being compromised. Many of these systems we rely on and there for safety and we’ve gotten used to it. They can’t risk sending out buggy software. Imagine if Boeing released bugs and other quality control issues.

Turns out it was a bad speed sensor module. I got it replaced and it works now.

Just found your post. I have the same/similar issue and post it here.

8 alerts showing at the same time

Just got my first Tesla ~ Model Y LR 29th, June, 2022. Several alerts showed yesterday and I have reported it to the service centers when it happened the first time on 13, July. The mobile service is coming 27, July. Anyone has experienced such issue? Any feedback/solutions would be much...
