Bummer. But also strange that we don't have thousands of other Model 3 owners complaining about this situation. Although the service center said that they saw "no evidence of malfunction" (in my case), a later review of the logs by one of the Tesla engineers did find some evidence of failed communication with one of the sensors.Have the Model 3 Long Range. Driven 6,000 out of 7,000 miles on Auto-Pilot. Problems started about 3 weeks ago. Only happens when moving right - moving left remains normal. Multiple issues. When signaling to go right and no cars anywhere nearby, the car just weaves back and forth towards the right lane before giving up. After trying twice, the right hand signal no longer works. So I have to take the car out of Auto Pilot and then re-initiate the right hand turn signal for it work and for AP to try again.
A related problem is that when passing a large truck on the right, and the truck is leaning left towards me, auto-pilot just slows the car down and refuses to let me pass. So can only pass if I take out of Auto-Pilot. Everything with AP remains normal on the left.
I took the car in for service. They replaced the SCCM and gave me back the vehicle. However, after I received the car back, the same problems were there and I returned the car. They claim that there are no issues with any sensors or cameras on the right hand side. They were able to recreate all my stated problems, capture videos, and now acknowledge there is a problem and that others have the same problem. However, they said they cannot resolve it and have handed this over to central Engineering for a future fix. They told me to pickup the car tomorrow since there is nothing they can do to fix the problem.
They are supposed to be sending an engineer to my house to test and potentially replace the sensor, but we're still working out the scheduling for that. I will post here if they are actually able to fix the problem.
