M3 bumping right on Autosteer

[craigpugsley]

Quick question: has anyone else seen this behaviour? While on Autosteer, maybe one time out of ten, the car will decide to track as close to the right-hand side of the lane you’re in as it can, and ‘bump’ along - constantly doing small steering movements right. It feels like it’s bumping along against some invisible right side wall. If you leave it, it feels like it’ll eventually get so close, it’ll cross the right side of the lane (haven’t tried for obv reasons). It feels both dangerous and uncomfortable.

Disengaging then re-engaging doesn’t change the behaviour. It just seems to magically fix itself after a few more miles. And then magically come back again.

Anyone else experienced this?

Perhaps worth recalibrating your cameras.

What does it show on the display in terms of car position on the road when it’s doing this?

Have you had your tracking adjusted? I had something similar years ago where the car tried to throw me off the road when engaging AP and it was the steering wheel position sensors. They might need calibrating, you can do it via the hidden service menu but given the importance of the steering, I’d let Tesla do it.

Probably someone told the car to favour the right…

Not experienced this. Needs to be reported to Service in my opinion.

Fantastic. Thanks very much for your - as always - super informed responses! Appreciate you taking the time to reply to me
Service centre it is, then!

It shows the car and road limits as normal, and it shows the car as (accurately) too close to the right of the lane. So, it knows it’s doing it.
