R2 High Speed Instability.

There were several versions of FDS/AP on my 2018 Model 3 that ping-ponged between the lane markers. If it only happens when using UHF, it might just be bad software that needs to be fixed.

You most likely need an alignment and/or tire balancing.....

Why would this have anything to do with alignment or tire balance IF it only does it when UHF is enabled?

What does UHF mean?

Ultra High Freqeuncy?

but here, most likely Universal Hands Free.

Drove two R2's back-to-back today. Used UHF at 80mph on the same stretch of freeway with zero issues of any kind FWIW.

Interestingly, I only get the wobble between 60-70 MPH, and not consistently. I haven't been able to reproduce it at 75+ or 55-, but I was somewhat limited by traffic during my testing so wasn't able to fully test the whole range. I was able to reproduce it at 65 enough to catch a video of it for the service tech, though he said his first impression is a software bug since there is no actual steering movement, just the wheel. It's in the shop being looked at now though, so we'll see...

Likewise….constant shimmy between 59 and about 67. Very smooth above 72 mph. Certainly not the end of the world but obviously something is amiss.
