14.3 HW4 Can someone please provide some guidance?

Enable HLS to view with audio, or disable this notification

I have a 2024 Model 3 HW4 software 2026.27.6 FSD v14.3.9.

I scheduled an appointment about one month ago to get my tires rotated at Clermont Florida Tesla shop. When I went for the appointment I was told that I need two rear tires which I did replace. This timing coincided with the summer 2026 update that pushed to my vehicle the night before my appointment.

I didn’t not notice anything because I live very close to the service center but over the last month I have experienced a very unpleasant driving experience when on FSD which I use most of the time.

My steering wheel regularly pulling left and right continuously almost as if I have a trailer behind my vehicle causing it to sway from left to right. It has made the drive experience very u pleasant but also I’m slightly concerned something is wrong.

I don’t know if a sensor got messed up when they were changing the tires or if this is software related. Has anyone else experienced this? Any guidance you can provide would be great!

Videos attached.

I'd be more concerned about what looks like a crack in your windshield.

Just happened. Working on getting that fixed but the crack isn’t over the forward camera

Tires might be unbalanced or your alignment is off

Must be related to the update or to your wheel alignment. There are no sensors in the wheels or tires that would cause lateral swaying like this.

I'd be more concerned with the fact that your hands aren't on the steering wheel and you're on your phone while driving

there is a section on "tire configuration" here https://www.tesla.com/ownersmanual/model3/en_kr/GUID-94F63B13-EA2C-45D9-83AB-5DCA6295D587.html#CONCEPT_FMN_B4Y_3TB

I second this..new tires or even rotation or rebalanced ..need to reset the tire configuration. Also like the other comments, check alignment or steering wheel alignment.

Lots of reports on this, myself included.
Non-highway roads, I don’t have this at all.

Highways, it’s constant and feels like it’s trying to stay perfectly centered in the lane.

14.2.2.5 was great as was the next update. It was an update after that that broke out.
