So...joined team Tesla today with a new YL! Picked up from Giga Texas but no tour included unfortunately. Still, for a first time Tesla family it was an easy experience overall and I really like the size the YL provides for huge hockey bags. FSD is of course incredible and easy to use. Not sure if I'm impressed with the Grok AI though.

Supposed to be my 'work' car to the office and trips within Texas, but pretty sure my wife will be stealing it.

Do not keep driving it as the family car. That stack of alerts is a brake-and-stability failure, not a calibration nuisance. Power assist down plus ABS/ESC/TCS off means a hard pedal and much worse stopping in a panic or on wet Houston pavement. Factory-fresh cars with that cascade have gone straight into service; TMC has the same 2026 Y alert list.
What I would do this week
1. Stop treating Oct 15 as the answer.

Open a new service request in the app today. Title it something like:

"UNSAFE TO DRIVE ABS / power brake assist / ESC disabled on brand-new vehicle. Need same-week mobile or drop-off + loaner."

Paste the exact alert text, date/time, Austin-to-Houston drive, that it came back after a reset, and that they told her to wait until Oct 15.
Ask for, in writing in the app:

• Mobile service or an earlier drop-off at a Houston-area center
• A loaner (warranty work over a few hours usually qualifies; availability is the fight)
• Confirmation this is warranty, not customer-pay

If the chat bot or advisor repeats Oct 15, ask for a service manager and the regional service number. Call Tesla Roadside again and say the car is not safely operable and you need a covered tow to the nearest Houston service center. First tow being cancelled does not make a second warrantable breakdown your bill. Tesla's own roadside policy covers towing for a warrantable malfunction to the nearest SC (typically up to 500 miles).
2. Do not "finish the month" on it.

Use another car, a rental, or Uber until it is diagnosed. If you must move it a short distance, go slow, leave huge following distance, and assume the pedal will be heavy and the wheels can lock.
3. Paper the file the same day.

Keep:

• Screenshots of every alert
• App chat / tow request / cancellation
• The Oct 15 appointment screenshot
• A short written timeline (pickup Friday Austin Waller errors reset recurrence Tesla said next tow is on you)

Email Tesla (service + the delivery advisor if you still have one) and say: this is a substantial safety defect on a vehicle delivered days ago; you are requesting immediate repair or a replacement loaner; you will not regularly operate the car with ABS and brake assist inoperative.
4. Lemon-law clock starts now.

Texas treats this as a serious safety hazard. Presumption of a lemon is often 2 failed repair attempts on a safety defect, or 30 days out of service, within the first 24 months / 24,000 miles plus notice to the manufacturer.
You do not need four visits yet. You do need every visit and every "we can't see you until October" note documented. File with TxDMV later if they stall; $35 complaint is the formal last-chance notice.
5. Optional pressure that actually moves Tesla.

• NHTSA vehicle-safety complaint (nhtsa.gov/report-a-vehicle-safety-problem). Same alert list, VIN, "new delivery, recurring, service date a month out."
• If they still refuse an earlier slot or loaner, a short certified letter to Tesla, Inc. (warranty / consumer affairs) restating the safety issue.

What I would not do

• Daily-drive it to October 15
• Accept "you already used roadside once" as a reason to pay for a second tow on a 2-day-old car
• Let them close the ticket as "could not duplicate" without a drive-cycle log and a written diagnosis
• Trade verbal promises; only app messages and emails count later

Likely causes on a days-old Y with that exact alert dump are 12V/low-voltage, a brake-controller / ESP module, a harness/connector from factory, or a sensor pack sometimes a quick part, sometimes not. Either way it is Tesla's problem on a new warranty car.
