I’ve received this error 3 or 4 times since taking delivery of my Y 5 weeks ago. It goes away after a few seconds to a minute and I haven’t been able to reproduce it or notice a pattern. The turn signals appear to be working fine according to the display but I haven’t been able to observe the exterior lights as I’m driving. Anyone else experience this? Might just be a software glitch.
I had this exact same message today [11/22/2020] in my December 2018 Model 3 midrange -- the turn signals all work fine, this was on software 44.15; while I was driving last week I had intermittent warnings show up but they were so short that I could not read them while driving, I guess they complained about the same thing. Does anybody have some insight into this?
My wife just got this after a pressure spray type car wash. Next drive she got that message. Turn signals were rapid on the side they worked, and a headlight is kaput and wet inside. I suppose I need a new headlight at least.
