I've never seen these errors on track myself, which is why I'd suggest you may have something wrong with your car.
Also, I'm not a proponent of high tyre pressures generally, but your pressures seem a little low for the track.

Track Mode - a day with HOD @ Laguna - my personal observations…

42 psi is the street pressures…I got to 50 psi during the 1st session - I bleed them down to 38 psi "hot" when I came in from 1st session in prep. for session #2…
you consider 38 psi to be "low" for the track? to maximize grip you normally run pressures pretty low at the track - 38 psi is actually pretty high- but I've spoken with other's who have tracked the model 3 and any lower and you lose shoulder integrity on the low profile sports tires…
anyone have any actual experience to share as to proper hot tire pressures for the Model 3 at the track.

I spoke with people who should know (I can't say more) while at the track - and they suggest these errors are a known/common issues but Tesla isn't focusing on the 3 and track mode as the future lies elsewhere for a more appropriate track drive train and overall vehicle…but hey what do I know I'm just some guy on the internet.
Yes, me for a start.
How much camber have you got on the front & rear?
38 hot is too low for a Model 3 IMO. But I'll let others chip in because it seems you don't think I have enough experience. Maybe I'm the one who's got it wrong.

well 42 cold is recommended street pressures - and typically you run a few pounds less on track hot to get more contact patch
@Electric Dream what pressures "hot" do you target on track?
I'm not saying your wrong - I'm just saying I don't know what others are doing...

I run 34 hot on RE71R (with susp, and camber etc) and it has worked out great so far. I believe others here run nearly the same.

The problem you encountered with TrackMode is abnormal. Many of us track our 3 at Laguna Seca and Buttonwillow without any issues from TrackMode.
Would be beneficial for the community to learn from your experience if you care to share more.
Can’t argue about the endurance and lack of supercharging at the track. None the less, still run to rip a few fast lap and passing P cars while doing so.

warning came in 2nd session after I’lower the hot pressures to 38 hot - tire pressures were below 40 psi when are the errors were thrown
tire pressures are on screen in post #99 - pressures were coming up - but I aborted the session by lap #3 dues to the software faults - note the right rear was at 38 psi in the pics - right rear is common heavily loaded at thunderhill so it comes up faster

Did you set the TPMS to use/learn the low pressure? I think it’s under the Service menu.
I've shredded two sets of PS4S though.
Just some more data.
Kind of unrelated, but related question. I am just going over tires at tirerack. It appears the Model 3 has very limited tire options in 18s for the track. Many tires offered are too small, to keep close to stock diameter. You are basically stuck with Bridgestone RE71 or Federal tires. Anyone else have recommendation that are close to the stock diameter? Around 26-26.5
OP, you probably need to bring your car in for a scan. I spoke to a tesla tech. Every message that comes on and goes away do generate a log, Tesla will be able to see it. I had issues similar to that on my Model X, they found a ton of error codes from failed updates

He's not said he's running any camber though. I can't see how 34 hot will work well with no camber and PS4s.
@dortor4ev I've done 20 plus track days running almost every session with my Model 3 and the only time that I saw that many warning at once was when I was sliding back and forth for several seconds. As you mention, after the car reset, everything is back to normal. I finished the following sessions good as new.
Your analysis is spot on for Model 3 as a track car and I understand the hesitation to use it on track when you have a GT3. However, with proper charging, it's still very fun to drive.
I think there is a chademo charger in the Walmart plaza next to Thill, that's probably your best chance for fast charging between sessions.

there are now 3 chademo chargers in willows! yeah! one a walmart and two at black bear diner!
@dortor4ev Thanks for all the great information in this thread! I just bought a Model 3 Performance last month, after somebody rear-ended my BMW M4 and State Farm declared it a total loss.
I used to regularly take my M4 to ThunderHill and Laguna Seca (mainly with HoD) and had been wondered if it was practical to take the Tesla to the track.
