> When I got my Model S, they did the same thing, the DRL's turned off on the side that the turn signal was flashing. Thought It looked crappy, even had people stop me saying my DRL was acting Flaky. Apparently enough people complained about it, where in a Over the air software update, Tesla changed the behavior so that now instead of turn off, it just dims the DRL by about 50%. Looks much better now. Cant stand when it turned off.
