I assume the speeds are comparable. How about the depreciation speed compared to the refresh MS?
reporting back after a few days with the update. It seems to have minimized the problem if the car is warmed up. But on a full cold start (like sitting outside overnight), I still have that 30-40mph vibration. Suspension height doesn’t matter.

I think that perhaps some of this residual, “I’m not sure if I still feel it after the update” vibrations when it’s cold may be, but what do I know

My car has always done this, since new. I assumed it was just inherent of the AWD system. It is easily replicatable and happens ever time I turn from my garage to the length of my driveway. There are "skidmarks" outside my garage due to the different wheel speeds during the turn.

Nothing to do with the AWD system. Read the replies after that post...

Bad wording... differential effect. I'm overly familiar with the Ackerman effect. My wife has a FWD vehicle and doesn't have this effect. Does Kia have better front differential control than Tesla?

It's nothing to do with it, as mentioned. Switch your summer tires out for all-seasons/winters, and the problem goes away. Think of it as the car letting you know it's not got quite as much traction as it would do if it were warmer out...

Corrected wording so I don't get 100 responses stating the same thing...

I'm trying to remember the "exact" temperatures, but I can say I properly notice it when the temperature is consistently in the low 50s or slightly below that. I don't notice it in the 60s and up.

Depends on the car, but absolutely, yes.
Explaining the "Ackermann Effect" in the 2014 Corvette Stingray - McGrath Auto Blog
If you take the all-new Stingray for a drive, you may notice something before you even leave the parking lot. This little something may seem like a defect, but it’s not. It’s called the “Ackermann Effect”, and although the issue was resolved 200 years ago, Chevy left it alone on the Corvette...

Noted. It rarely drops to 50* around here.
I'll mention it to my Service Center next time I'm there. I suspect something may be wrong. I wish there was another Plaid in my area to take a ride in to validate some of my issues.

2009 Corvette Z06? 2015 Model S P90D? Neither did it. My 2010 Cadillac Escalade AWD did.Depends on the car, but absolutely, yes.

If you're in Lafayette, LA, it can definitely hit those temps, it seems.
Can you have someone record it from outside the vehicle? It sounds normal to me, but if you're seeing these issues in the 60s and 70s and above, something isn't right.
