We have an 2015 S85D. A little while ago the Nav started to wander significantly, causing problems with the TACC. My wife would find herself during her commute on 167 and 18 suddenly having the car think she was on a side street, quickly slowing the car from highway speeds to city speeds. We took the car to Tesla and they replaced the Connectivity Board less than a month ago. We'd already had the eMMC replacement done by Tesla, so this part was replaced under warranty.
Most of the time since, it's been better. There still seems to be an issue in the East Pierce County/South King County areas -- along 167/410/18. Traveling along 512/5/710 seems to be pretty consistently accurate, but she drives that route less.
Is anyone else having issues with the Nav/GPS wandering off your actual location in that area? We've owned the car since it was new, and not had any issues until the last couple of months. While she is driving that particular route more often now than before, we've driven 167/410 hundreds, if not thousands, of times, and 18 often enough to know that it hadn't happened until recently.
I've attached a track of this morning's drive from Puyallup to Covington -- or at least that's where she actually drove. The tracked route wanders off of 167 around the 410 interchange, and never makes its way back to her true route from 167 to 18.
