Model S P90D w/AP3.0
I've had almost the identical experience if you check my previous post. Tesla clained it's an AP fluke failure that needs a service visit. Our cars are simmilar in 2016 AP 2.0 so I wonder if this is demonstrating a trend.
I've been dealing with the same thing on the highway since 2019.8.5/6. AP deactivates every half mile or so, so using it is entirely useless. I basically can't use AP anymore and I have a road trip down to Florida in 2 weeks. I'm pretty upset about this, as it breaks a major feature of the car.
I had set up a service appointment last week to look at the radar (still on 2019.8.6 at that point), but got a phone call to cancel it. They pulled the logs and claimed it was due to the lane lines being too thin. That doesn't make sense because I'm finding this occurs on freshly paved and painted areas of the highway (I-75 in Atlanta). But I have someone coming tomorrow morning to do the recalled airbag swap, so I'll grill them about it.
Interestingly, I can't reproduce it on surface streets. It only occurs on highways. There seems to be correlation with bridges and overpasses, but it's not consistent. It is quite frustrating!
