While driving 2020 MY Performance with 5,000 miles, lost power assist steering; antilock braking; traction control; regen braking. Tried soft/ hard rebooting, full power down reset, and also leaving vehicle for 30 minutes. Called into Tesla, after they reviewed errors, was instructed to take it to the service center. They have had it for about a week so far and i was updated yesterday they changed out a defective wiring connector, but it only restored the power steering.

While this didn’t happen while I was driving, I had pretty much the same list of errors and after 2 mobile visits and 1 service center visit, I was told that they replaced the ABS module. Been a few months and i believe it is fixed now.

Had something similar happen right after I took delivery of my Model Y. Was at the service center for ~1.5 weeks and turned out to be a broken pin in a wiring harness. Has been fine since.

Update from the service center 1/4/21- They believe the front drive unit is causing the issues, they have ordered a new unit from the factory, but expect it to take a few weeks. The service center rep has been great with updates, but I'm very concerned to have such a major component fail in the first months of ownership.

Hi there,
I have exactly the same symptoms (2021 Model Y took delivery Nov 15, 2020).

The issue with my case was a serious mis-alignment of wheels. They did the alignment and then everything was fine. took a week in SC.

I attached a pic of my display alerts. Scared the *sugar* out of me. I need service. Today was fine but tomorrow it can haunt me again. 2020 model 3- 8.5k miles

Got the 2021 Model Y on May 28, 2021, and first time got the errors: ESP_a053 ABS (anti-lock braking system disabled), UL_a020 Steering assist reduced, DL_a222 Stability control disabled, DL_a039 Regenerative braking disabled, DL_a223 Traction Control disabled on Jun 8, 2021 on the NJTPK. Took in in and they tightened some part that was loose. Again Jul 17, 2021 same errors appeared (tried soft reboot, fun reboot from the Menu) did not work.... Just got it towed away. Any ideas from the community on what might be the issue.
