Starting about 3 weeks ago, my 2020 Model Y LR began dropping out of FSD mode and alerting me to take over immediately. Upon taking control, a message on the Nav screen said it failed due to a system error. Additionally, I began to experience FSD randomly slowing down and then momentarily signaling a left or right turn for no apparent reason. In all these cases I never looked closely at the Nav screen as I was busy taking over all driving responsibilities. As the frequency of occurrence began to increase I was able to calmly take over and was able to closely observe the Nav screen. What is showed was that FSD was properly charting a path down the road BUT the GPS was placing the car off the road. Often it looked like I was driving through people's front lawns and several times driving in the river. After a short interval, the GPS corrects itself and properly shows the location of the car. I found that this also happens with just Autopilot or TACC engaged.
Another odd thing I have noticed is that the windshield wipers automatically engage and spray fluid. A message on the Nav says the front cameras are obscured. In both cases the windshield is perfectly clean and it is not raining.
Contacting Tesla Service, they asked me to perform a "scroll wheel reset" which I did but with no improvement. I have a service visit scheduled for next week. I did have the front windshield replaced 14 months ago by Tesla due to a crack. I believe the GPS antenna is located in the same housing as the front cameras. Potentially, the mounting of the housing is at the root of this problem.
Anyone else experience such an issue?
