multiple systems disabled

Sounds like the computer is struggling, if an update hasn't fixed it yet then it's probably extremely rare or hardware related.
Maybe disable as many options as possible to check for improvement?

It started after the cold week we had last week here in ohio. The temperature is around 10°F for couple days. Don't know if it has anything to do with what happen. Im bringing my car on Wednesday for tesla to check.

On my 2023 MXP the service center ended up replacing the steering rack due to a faulty sensor and did realignment. No idea why the entire rack had to be replaced and not just the bad sensor. These issues need immediate service - they relate to safely operating the vehicle on a very basic level.

Yea. I want sooner but the earliest they have is next Wednesday. Hopefully it doesn't do anything crazy before then. We only have one car.

This is so weird.. My MXP just did this for the first time today too and it only happens sometimes when putting it into reverse. I think it's a software issue with the recent update. Traction control disabled, stability control disabled, automatic emergency braking disabled, reduced steering assist, something suspension too. Car can still drive just fine but it maintains it's speed instead of one pedal driving. I have to brake to make it slow down

My car couldn’t switch into gear and just kept rolling as if in neutral until I activated tow mode and that “fixed” it. But yeah I agree there’s some issue with software and sensors involved. You may want to report to service they can pull the car logs.

 

[worldtraveller]

same thing happened four times to my almost new 2023 MS. It's still in for repair, but technician thinks it due to a faulty steering rack. They also checked for loose connections,

 

[Milan Djabirov]

Yes, I ended up having a steering rack replaced for this - no idea how it’s related to this behavior, but it’s “encouraging” there’s commonality so hopefully yours will be fixed by same. Hasn’t happened again in 900 miles and multiple low speed maneuvers since.

Same problem for my '23 X.....service center advises new steering rack needed. I've seen this reported on here a few times already....I wonder if this is a more widespread problem in which Tesla will address with a new part?

 

[Milan Djabirov]

Hasn’t repeated since replacement. But it’s been only 1700 miles. I’m sure they are aware of it as they figured what to do without trying to replicate (just from the car logs.)

Mine did this once. Like better part of a dozen errors. Steering was effed, no regen braking, no arc, no abs. Suuuuper dangerous.

I blame tesla cheapibg out on the wiring harness and daisy chaining everything versus having multiple redundant systems

 

[pwambach]

This happened to me yesterday. All the same error messages. Today I went back to my garage, which is a level surface and put the car in the service mode. While in service mode, I ran 2 tests. “Reset Learned Tire Values” and “Calibrate Steering Column” twice. After these ran I exited service mode and it started working fine. I had full self driving back as well as sentry mode and brake regen.

 

[Milan Djabirov]

well for me putting the car in and out of tow mode “fixed” it but Tesla still seemed the steering rack sensor defective

 

[jokermc5]

Steering rack replaced for same fault model s had 1k on it. I wonder what caused this ? Bad part ?

 

[NewbyMaybe]

Lack of quality control. The racks aren't being tested thoroughly before bolting to the cars.

Today, I was backing out of my driveway and all of a sudden I heard a thunk (didn't hit anything). Right after, I received multiple warnings from my Tesla:
- stability control disabled
- traction control disabled
- steering assist disabled
- adaptive ride control disabled

When I drive her, there's no regenerative braking and I have to brake manually as well. I've sent a service request but the first available appt isn't for another 2 weeks. Kinda scared to drive the vehicle given the above warnings. Any idea what caused it? It's a new 2023 MS that's about 4 months old with 900 miles on it.

Hi, I’m wondering what the diagnosis and fix was? The exact same thing just happened to me even down to the loud thunk.

 

[Milan Djabirov]

Requires steering rack work/replacement in most cases shared here. You can clear these error codes by entering and exiting tow mode (in my case it helped) but I would not trust this not returning. The thump and codes is precisely what happened to me. Tesla said it replaced steering rack - 2023 MXP. No issues since.
