Center console/head unit will regularly lock up and eventually reboot when apple carplay is in use, cruise control, lane keep will turn off, and car will warn that adas is not available, backup camera does not work during this time. Hvac controls are not accessible during this time as well.
Since last October when a software update was performed on the vehicle I have had multiple(8-10) instances where the eyesight system caused the emergency braking to activate when no other vehicles were nearby and a crash was not imminent. Usually it has been when entering a left hand gentle curve with a guardrail nearby, but it has also happened going straight ahead. The audible and visual alerts appear and hard braking occurs. The braking is severe enough that on rain or snow covered roads a crash might occur. The dealer inspected the vehicle and claims they found the calibration was off but the problem has occurred 3 more times since the calibration. I have contacted the dealer again but they have refused to acknowledge the problem further.
