Yes. Specifically. I will also repost this to the mentioned thread. As that is where I had the conversation with another owner.
From my 4/4/2019 SC Visit:
Tesla remoted in to my X prior to my visit & seemed to already know what to do.
Here is the SC log, and the part they replaced:
Customer states received update 2019.8.3. New dialog appears constantly while in Drive: “Blindspot detection limited Camera visibility reduced"
Found during service that faults with LH repeater camera were present. Connections were solid to all cameras, replaced repeater camera due to issues. Confirmed during final test drive that blindspot, autosteer and other features are working as expected.
Correction: Blind Spot Warning General Diagnosis
Correction: Lamp - Side Repeater - Front - LH
Parts Replaced or Added
LAMP ASY, SIDE REPEATER (LH) (1034344-00- 1 B)
