Wiki Model X Refresh Issues Thread
- Thread starter studioloft
- Start date
Model X's have always been criticized for their overly-aggressive camber (wearing the inside of the tire faster than the outside). I've never heard of toe being an issue.
Toe also affects the entire tread. Not just the inside.

Anyone on 2022.12.3 been able to reproduce the rear seat restraint issue?

Based on our MS experience over the last 10 years, as long as toe is correct to Tesla's specs, excessive wear comes from too much factory camber. Nearly everyone does this nowadays because people can't drive and cars have gotten very fast/powerful. Next time you pull up next to a BMW, Audi, Etc, check out the rear wheel camber. It is insane.
The reason is that it minimizes lift-throttle oversteer. When entering a skid, untrained drivers will lift their foot off the accelerator. This will actually increase the skid and cause the car to spin out. The answer is to keep your foot in it and just steer into the skid. But people won't bother to go to a driving school to learn so they dial in crazy amount of rear camber in the rear wheels which will help minimize this behavior.
The inside wear was ridiculous w/ our 2012 MS with 21" wheels. One our 2018 we moved to the 19s and it's a lot better (the taller sidewall squishes more to keep more of the tire in contact w/ the road) so I haven't bothered w/ aftermarket kits.
I went w/ the 20s on the MX for the same reason.

I’ve had a total of 3 drives on 12.3 and no restraint fault yet. But I’m skeptical until I go a week without the error.
That’s encouraging. We’ll see, right?
I have it ready to download, but out of town until Sunday. I am traveling to Nashville next weekend so 2022.12.3 will get a full up test, long distance and super chargers.
People mix-up toe and camber all the time. I've seen it happen numerous times... especially in the context of the MX for some reason.
But yeah this car is cambered aggressively for a reason. It's a high performance "SUV" that is also extremely heavy. Reducing camber will reduce rear cornering grip (generally speaking). Not something I'd ever want to mess with.
I know just enough about car setup to know that I am not smarter than Tesla's engineers. Neither is the guy at your local mom-and-pop shop.
Did they put that in writing? Time to start posting screenshots on social media and sending copies of invoices to the ev pubs.
At any rate, not normal. You need to insist and be pushy about it.
Toe also has a big effect on tire wear.
Of course, but it should affect the entire tread. Not just the inside. It's *camber* that is responsible for asymmetric wear on the inside.
Just noticed 2022.12.3.1 just came out today. I'm out of town and haven't installed 2022.12.3 yet.
Just curious if you have gotten this put in yet? Most sites I've seen refer to the Hansshow version and just wondering how they compare, or is this the same thing?
Just relaying my own experience driving over 100k miles in 6 years. Consider trying it as a test for yourself.
Adjusting camber with aftermarket parts did not improve the excessive asymmetric wear but reducing the toe did. Perhaps because of the camber the toe impact is also asymetric.
According to my shop my tires developed a scalloped wear finding which is attributed to a “chipping” mechanism which is sensitive to toe. This prompted us to minimize the toe and we were pleased to find that not only did the scallop pattern not appear on the new tires but that the asymetric wear was noticeably reduced and tire life prolonged.

Plaid is scary!
So far, my error is gone with this update. Fingers crossed.
I installed 12.3 2 days ago and 12.3.1 yesterday. no rear restraint fault yet. update notes are opaque as usual for the issues we care about.

I had scheduled service with Tesla for the rear restraint issue about two weeks ago with an appointment later in May. They just called me to let me know the most recent update fixed the error and if I was okay canceling the service. I have not had an error since updating, so I canceled.
Agree with everyone here that the restraint error is solved. I’ve had 12 distinct drives without the error. Not sure if the Supercharging glitches are solved as all my drives were shorter and in town.

Happy to report that almost three full months after taking delivery, my SC fully repaired all items identified around delivery time. Car was with the Corte Madera, CA Service Center for a week, and they did an awesome job.
- small fray of the stitching on the dashboard resulted in them replacing the entire dashboard top. That cant be cheap for Tesla.
- misaligned driver door now completely in line
- Falcon wing doors and front doors in perfect alignment
- fixed a rattle/static coming from front speaker grille
For those with issues be patient and persistent!

Good news! Still waiting to see if the long drive/Supercharging issues have been fixed. I had the frozen backup camera/flashing warning light issues on a road trip earlier this month on 2022.8.3. Don’t have any road trips for awhile to test 12.3.1. Car performs flawlessly in town. I only had the restraint error once on 8.2, fixed with wheel size change reboot.
I think I may have this rattle. Can you take a picture of this underbelly cover so I know where to look? TIA
My left turn signal button is sometimes unresponsive. I thought it was some kind of half-assed safety feature, since it seems to happen when I try to signal a lane change from highway middle lane to highway speed lane and the speed lane has little or no shoulder between it and a barrier wall.
I have a service appointment upcoming for the rear seat warning light. I'll see if I can add the turn signal fault to it.
