It appears the latest Tesla vehicle software, version 5.11, made changes in the CAN bus messages for turn signals, and perhaps others as well. I just had my vehicle's annual service performed on Wednesday, which included updating the software from 5.9 to 5.11. On the drive home, the MobilEye Lane Departure warning sounded off every time I changed lanes, even with the turn signals on. I checked with the install tech, who checked with MobilEye tech support. This is what he reported: "Looks like a couple weeks minimum for the software update from Mobileye, they have been getting calls today from other dealers with same issue. They also said it may not be receiving brake signals as well. For now you can turn off the lane departure by pushing the center button on the display three times or until it shows the lane departure screen, then use the left button to turn it to zero. That's the best we can do for now, once they release an update we can get the vehicle in to recalibrate the system and adjust the speed as well."
