2021+ Model S and Model S Plaid Refresh Issues Thread

[WilliamG]

@dennis If it was truly a firmware issue, wouldn't we all have the condition (all, meaning those on that same firmware version and configuration)?

Not necessarily. Remember you had a battery mention in your 32.5 update. I hadn’t seen that reported anywhere else. Very strange.

Had the Model S LR since Sept 2nd. have over 80 miles (yes we don't drive far!) and it is still calibrating. When did your car stop Calibrating so I could at least try cruise control of FSD?

also still on 2021.11.102 software, no update. and it won't even find my iphone as a hotspot (but it is connected to my home wifi network).

 

[VM0412]

In my case there's an alert from the BMS.
@VM0412 have you done the "dynotest" mode to see if you have any alerts like mine?

I haven’t done this. Will check when I get a chance though.

 

[MarcG]

Not asking about dyno mode (but thank you) -- rather the Tes Lax view that @MarkG got working. ...I wasn't aware that anyone had gotten CANbus integration working on a MS refresh yet. Is there a video somewhere showing what it takes?

Head over to this thread for all the details (no video but I posted a lot of details & photos):

Diagnostic Port Index

Nope! The diag connector on the 2021+ refresh cars actually turn off the 12v when the car sleeps. This is new behavior and fantastic for our purposes here. (the previous s/x diag 12v was always on) Excellent! @JWardell heads-up, I just ordered a dual-bus canserver from you :)

Yes! Please keep us posed. So far the 3 of us have the exact same issue. We need to keep each other informed on how to get this resolved.

Have any of the three of you taken your cars to the service center? Is Tesla aware that I am not the only one with this issue?

It might be an issue related to how the firmware goes about balancing a cell that is out of spec. In that case only those who had that situation would be affected by the bad code.

My service invoice specifically said that it was not a hardware problem. I know that the service tech ran battery diagnostics and got engineering involved when he was not able to resolve the issue.

My earliest appt is Oct 4th, but I have a friend over the yrs that works at a Service Ctr as a SA. So Im waiting for her to get back in so she can nudge a tech for me. Hopefully tomorrow.

Edit: I actually went to a the Van Nuys SC today in the hopes that I could talk to a tech. The girl I spoke with is a "supervisor" and used to be a tech. She says I should leave it at a relatively low SOC and let it rest there so the pack and balance. (the opposite of every other tech has said of course)
She could/would not let me speak to a tech directly.

I actually have this cable from my other cars! Where does it plug in on the refresh cars?

I think it’s right above the inductive charger. When I had my mysterious hard reset and I couldn’t get anything working again the tech said he plugged in right above the inductive chargers for phones etc. Not sure how that trim piece comes off, mind.

Yes, thanks! Found it!

Think the manual states 50 miles. But it typically needs to be 50 ”straight”, well marked miles for the cameras to calibrate. I would try driving on a freeway (if possible) for 15 - 20 miles. I think the manual has more information on camera calibration.

FYI the Maxwell cable I bought a few yrs back designed for 2015+ does not send data to the ODBII on the 2021 MS. I happen to have another maxwell cable, non-terminated, so I will have a new female ODB in a couple days and wire it up.

Don't be shy about requesting (insisting) the interior and exterior alignment be addressed by a 3rd party Tesla-certified body shop. This is what did the trick for our X trunk alignment issues.

I asked them to refer me to a 3rd party certified shop to address my issues and they came back very confused, saying they do not do that and fix these things in house, but could ask if I had a specific shop in mind. Not quite sure how to proceed now, will keep insisting.

 

[Desert Dave]

Update on this, I canceled my mobile appt after they messaged me (below). Makes sense, I haven’t had any alerts or any real issues. I think I’ve just been in my head about a lot of it. My max miles went up the next day to 367, so seems very variable.

I hope the BMS "unlearns" my earlier aggressive driving style when I first got it and gives me a higher mileage estimate

My Plaid took a little over 200 miles for FSD and I am still at 99% at 350 miles for auto shift into park.

Ooh another issue! This black part of the mirror mount is smacking against the paint when I close the driver’s side door, leaving scuffing on the black plastic and dinging the paint.

I'm having problems finding the problem. Could you circle it?

This question maybe too early to ask but maybe some knows the answer. Since Tesla’s don’t have spare tires What do you do when you get a flat on the road. Get towed? To where? Is there something Sold to temporarily inflate your tire or does Tesla not recommend that?

Roadside. They will either bring you a loaner wheel and put your flat in the trunk and you arrange for a replacement through the service center - returning the loaner wheel. Or you are towed.

They're BS'ing you to save $ or don't know.
Here's the shop that the SC in White Plains, NY uses...

Tedesco Auto Body | Accident Repair | New Rochelle, NY

Welcome to Tedesco Auto Body. New Rochelle's most trusted collision repair facility. We fix everything from dents and dings to large scale accident damage.

www.tedescoautobody.com

They were awesome with communications, diagnosis of many body defects we hadn't even noticed, and repair of the issue that SC couldn't address (4Q20 MX delivery obviously rushed out of the factory because trunk lid hinge bolts weren't tightened down prior to installing glass panel, so it was never going to be aligned without removing the glass, which is incredibly time intensive due to other body parts that require removal).

See on their website they have this logo below...and they are also an approved body shop for Porsche. Maybe you can google locally and find a listing for "Tesla Approved Body Shop"

Thanks. Is it better to use Tesla’s roadside or AAA. I ask this question because I’m taking a 12 day road trip and want to be prepared.
